As the number of electric vehicles on the road continues to increase, the demand for EV Charging Infrastructure has also reached an unprecedented level. Low-power slow chargers take a long time to fully charge EVs, limiting the charging experience for vehicle owners, especially for drivers who need to travel long distances. High-power chargers significantly improve charging efficiency, reduce charging time, and enhance the market competitiveness of electric vehicles for long journeys. However, the high heat generated by high-power charging cannot be ignored, as it not only affects charging efficiency but also relates to Electrical Safety. Efficient Liquid Cooling technology has emerged as a solution.   This article will briefly discuss how liquid cooling technology serves high-power charging for EVs, the classification of liquid-cooled charging connectors, and the benefits for businesses.   What is Liquid Cooling? We know that conductors all have resistance and will generate heat due to the thermal effect of current. Under a 250A current, the temperature rise of an ordinary 80 square DC charging plug is about 40K.   As the charging current increases, the heat generated by the current also becomes more significant. To keep charging safe, we must ensure that the temperature of the charging connector terminals and cables is within an appropriate range.   Although increasing the conductor cross-sectional area can solve this problem, it will also increase the weight of the cable and make it more difficult to operate. However, using liquid-cooled high-power charging technology, the Cooling Efficiency is higher, and the weight of the charging cable is lighter.   Liquid-cooled charging uses a liquid cooling medium to circulate under the propulsion of a power pump, carrying away the heat generated by the cable and charging connector, and reducing the temperature at the hot components, allowing the charging plug to withstand a larger current.   The cooling medium is divided into oil cooling and water cooling. Oil cooling is usually immersion cooling, with the medium being dimethyl silicone oil or E4 CCF, which have very high heat exchange efficiency. The water cooling medium is water plus ethylene glycol solution, although the cooling effect is limited due to the physical properties of water, it is more environmentally friendly and degradable.   The commonly mentioned liquid cooling system consists of pumps, fans, oil tanks, and connecting pipes, a compact system with high cooling capacity. It can be divided into automatic control and non-automatic control liquid cooling systems, depending on whether the charger needs to control the operation power of the pump and fan.   Liquid Cooled Charging Connectors According to the standards they meet, liquid-cooled charging connectors can be divided into CCS2/CCS1/NACS (TESLA DC)/GB/T/CHAOJI liquid-cooled charging connectors, which are used in corresponding standard DC Fast Chargers. The CCS2 is a combined AC and DC charging interface, with the standard referring to IEC 62196. It applies to Europe and most regions. The upper part is the AC interface, the lower part is the DC charging interface, and there are no electronic locks or hooks.   The CCS1 is also a combined AC and DC charging interface, with the standard referring to SAE J1772. It applies to the United States and countries such as Japan and South Korea. The upper part is AC and the lower part is DC interface, without electronic locks and with hooks.   NACS is the new charging interface announced by Tesla, and its current standard is defined as SAE J3400. It uses a shared AC and DC interface, without electronic locks and hooks.   The GB/T charging connector is based on Version2015 of the DC charging plug to develop the liquid-cooled plug, with the electronic lock on the charging connector and with hooks.   CHAOJI is a new standard jointly developed by China, Japan, Germany, and other countries, without electronic locks and hooks.   As a leading global professional charging plug solution provider, Workersbee’s CCS1 and CCS2 charging plugs adopt an integrated design, simple generous, and easy to handle. At the same time, they are compatible with natural cooling and liquid cooling.   The charging peak of the CCS2 liquid-cooled charging plug can reach 700A, with a rated current of 500A. With its safe and reliable performance, it has passed CE and TUV certifications and has always been a trusted partner of customers. For high-frequency use plug terminals, from the perspective of maintenance costs of business partners, the terminal quick change design is applied to avoid the high cost of replacing the whole piece. This technology has also received positive feedback from the market.   How Does Liquid Cooling Help High Power Charging? Liquid cooling technology plays a crucial role in High-power Charging. Uses liquid to absorb and transfer heat, achieving efficient heat dissipation, ensuring that charging equipment can maintain an appropriate and stable temperature range during high power operation, thereby safety and reliability of the charging process.   The power pump promotes the circulation of the cooling liquid, which carries away a large amount of heat, significantly improving the current transmission efficiency of the charging cable and reducing the risk of cable damage due to overheating.   Since the liquid cooling technology can effectively reduce the temperature of the charging system, it allows for higher charging currents and voltages, achieving faster charging speeds and improving charging efficiency. It ensures the system's stable operation and extends the service life of the equipment.   Benefits of Liquid Cooling Technology for Businesses 1.

In the previous article, we discussed the importance of liquid cooling technology for DC Fast Charging, which enables electric vehicles to achieve excellent charging experiences. This includes enhancing the charging power limit of High-power charger (HPC), achieving more efficient, energy-saving, and reliable charging.   This article will delve further into the key components of liquid cooling charging, providing insights to help you choose suitable products for the Plug-in EV Charging business.   The main components of the liquid-cooled charging plug include the Coupling Part, Enclosure, Liquid-cooling Assembly Part, Terminal Pin, Sealing Part, and Cable Clip.   Among them, the Liquid Cooling Assembly is the key component of the liquid-cooled charging plug. Due to the existence of contact resistance and connection resistance, the charging plug pin terminal heats up more than other parts like the cable conductor during Rapid Charging, necessitating additional forced cooling. This is where the liquid cooling assembly comes in, establishing a cooling connection through its structure and utilizing the coolant circulation to achieve heat dissipation. The design principle of the liquid cooling assembly is to have a simple structure, easy production, and most importantly, to ensure good temperature rise performance. The basic structure includes joints, screws, fixing nuts, thermal conductive materials, and seals. The double-sided joints are responsible for the inflow and outflow of coolant, creating a sealing environment by over-connecting with the liquid cooling tube and meeting the sealing requirements of the coolant. Generally, a simple and easy-to-operate pagoda joint structure is adopted, with a smooth surface to avoid sharp structures causing damage to the liquid cooling tube. For water cooling solutions, the coolant does not directly contact the metal conductor. The thermal conductive material is located between the terminal pin and the coolant to conduct heat, needing to balance thermal conductivity and insulation. Compared to ordinary DC cables, Liquid-cooled Cables not only have conductors but also integrate a coolant channel, i.e., the liquid cooling tube. The liquid cooling tube carries the coolant, the conductor wraps around the liquid cooling tube, and the outer layer is insulated. The structure of the liquid-cooled cable determines the internal structure design of the charging plug.   Public Charging Infrastructure has the following standards when choosing liquid-cooled cables: 1. Good flexibility, avoiding stiffness for convenient handling. 2. Good appearance, avoiding excessively thin outer jacket due to the pursuit of a small cable diameter. 3. Low temperature rise of the outer sheath to ensure a good charging experience and safety. 4. Excellent cable and pin welding quality to ensure the reliability of the Liquid cooling HPC.   The Liquid Cooling tube, as the key component of the liquid-cooled cable, plays a crucial role in transferring the coolant and heat. The inner diameter of the liquid cooling tube affects the overall flow resistance. The smaller the inner diameter, the greater the flow resistance, and the lower the efficiency of liquid cooling.   Electric Vehicle Supply Equipment (EVSE) liquid-cooled cables require limiting charging when beyond a certain length - one reason is that longer cables generate more heat, and another reason is that the longer cables have greater flow resistance. However, it also has to consider the lightweight of the cable. The outer diameter of the liquid cooling tube cannot be too large, which requires a balanced solution. In addition, The liquid cooling tube also needs to have a certain strength, sufficient deformation, and toughness.   In EV Ultra-Fast Charging, another important component is the Liquid Cooling System, which consists of a pump, radiator, oil tank, and connecting pipes. The heated coolant is cooled through the heat exchanger and then returned to the oil tank, and the cooled coolant is pumped back to the liquid cooled charging plug through the coolant pump. Liquid cooling systems can be categorized into automatic control and non-automatic control systems based on whether a charger is needed to control the operation of the pump and heat exchanger. Typically, liquid cooling systems include temperature sensors, liquid level sensors, pressure sensors, and other functional components. For automatic control systems, the charger only needs to provide power and start signals.

In the previous articles, we have fully understood the important role of liquid cooling technology in DC fast charging and become familiar with some key components. Before the liquid-cooled charging cables are truly put into use in Electric vehicle infrastructure, strict and comprehensive testing is critical, as these tests are closely related to the safety and reliability of liquid-cooled charging. In this article, we will briefly introduce some key tests for liquid-cooled charging plugs/cables to help you face high-power EV charging solutions with more confidence. The following tests may be involved to ensure that the liquid-cooled charging equipment maintains stable performance and safety during high-power transmission and long-term operation.   1. Sealing Test This primarily includes Air Tightness Testing, Leakage Testing, and High-temperature Operation Testing, which are particularly important for Eco-friendly EV charging. Air tightness testing aims to detect the sealing performance of the liquid-cooled tubes and connectors and can be used as an equivalent test method to IP67. Compared to the IP67 submersion test, the air tightness test can be conducted without causing damage. Whether the air tightness meets the standard can be judged by the leakage rate. Leakage testing is a type test used to verify the long-term sealing performance of various components and the compatibility of the coolant. The high-temperature operation test is conducted to verify whether the sealing components remain effective at high temperatures.   2. Temperature Rise Test The Temperature Rise Test is a fundamental test for liquid-cooled charging equipment. In the power-on state, the temperature difference between the charging plug, cable, and other components and the ambient temperature is the temperature rise at each test point. This is an important indicator when using High-power chargers. The liquid-cooled plug test requires the collection of the temperature, flow rate, and pressure values of the inlet and outlet liquid cooling tubes. This includes tests when the liquid cooling system is turned on and off, meaning it has two rated current values. The temperature rise under each current is converted into a derating curve of the charging plug to determine the allowable rated current at different ambient temperatures. Additionally, a Short-term Failure Test of the Liquid Cooling System is necessary to simulate the safety performance of the liquid cooling plug when the system suddenly fails. It is required that after the test, there is no damage or leakage in the cable, liquid cooling tube, and other components of the charging plug. The temperature rise test is an important gatekeeper for achieving Efficient energy management.   3. Liquid Cooled Tube Strength Test As a key component of the liquid-cooled cable, the liquid-cooled tube may not only be frequently bent but also bear the pressure of the coolant. Therefore, it is common to measure the structural strength of the cable through a Bending Test to detect any bulges or breaks in the cable after repeated bending. This ensures that the continuity of the conduct wires and the air tightness of the plug and liquid-cooled tube meet the standard requirements. The Burst Pressure Test of the liquid-cooled tube is conducted to evaluate the pressure resistance of the liquid-cooled pipe under high-pressure conditions, ensuring that it does not rupture or leak during actual use, thus guaranteeing the safety and reliability of the charging process.   4. Mechanical Performance Test This may include the Plug Insertion and Extraction Test (insertion and extraction force, insertion and extraction life, etc.), Impact Resistance Test (side strength test, vibration resistance test, etc.), and Cable Tensile Test (tensile strength, etc.). These tests are used to evaluate the reliability of the charging plug in daily use, ensuring that the mechanical structure is sturdy and durable, and capable of adapting to various harsh operating environments.   5. Durability Test In actual use, charging plugs may undergo multiple insertions and extractions, high temperatures, low temperatures, or other harsh conditions. Therefore, it is necessary to test their performance under these conditions to evaluate their service life and reliability. For example, by simulating the wear of long-term use, the lifespan and aging of the charging plug can be detected to ensure that it has sufficient durability. Additionally, salt spray tests and internal corrosion tests can assess the charging plug’s resistance to harsh environments such as moisture and salt corrosion.   6. Compatibility Test Charging plugs need to have broad compatibility to adapt to different vehicle models’ charging inlets and communication protocol requirements. It is necessary to ensure that the charging connector can properly connect to the charger and the electric vehicle and establish communication according to the predetermined charging protocol to initiate charging, guaranteeing widespread applicability in practical use.   7. Electrical Safety Test This includes insulation performance testing, leakage protection testing, overtemperature protection testing, current-voltage load testing, overcurrent, and overvoltage protection testing, as well as tests for protection against water, dust, and moisture. It ensures that the liquid-cooled charging cables can supply power stably under various operating conditions and will not cause dangerous incidents in possible abnormal or extreme situations, thus safeguarding the safety of users and vehicles.   8. User-Friendliness Test This involves simulating the actual usage scenarios of drivers to assess the comfort of the charging process from the user’s perspective. It includes noise testing, insertion, and extraction force testing, as well as the weight, size, flexibility, and ease of operation of the charging connector. The goal is to ensure a barrier-free and pleasant experience for users during the charging process.   Satisfactory Workersbee CCS2 Liquid Cooled DC Cable Temperature Rise Test Performance As a global leading charging plug solution provider, Workersbee’s product development has always been at the forefront of Sustainable charging technology.

The market penetration of electric vehicles has grown so significantly that it can no longer be ignored, accompanied by a huge demand for charging. What troubles the electric vehicle charging industry is not a lack of market, but rather the lack of reliability, complex charging experiences, and unsatisfactory return on investment. To gain more control in the market, we need to start with Electric vehicle infrastructure. AC charging and DC charging are absolutely mainstream. A thorough understanding of their pros and cons and value realization can help us plan and configure the charging network more strategically and embrace electric vehicles more proactively.   First, let's briefly understand the basic concepts of AC and DC charging.  AC Charging uses an alternating current power source to charge an electric vehicle's battery. The AC from the grid is converted to DC by the vehicle’s onboard charger and stored in the battery. This setup means that the efficiency of AC charging is limited not only by the charger but also by the onboard charger（OBC）.    Therefore, AC charging is generally slower. Although some AC chargers are known as "Rapid Charging," they are not in the same league as DC Fast Charging. These faster AC chargers are usually referred to as Level 2 Chargers, while the lower ones are called Level 1 Chargers.    While the Charging Speed of AC charging is slower, the equipment costs are lower, they are easier to install, and the requirements for the surrounding environment and the grid are relatively low. They require minimal electrical upgrades and are easier to maintain and operate. For drivers, the charging cost is also lower. Therefore, AC chargers are well-suited for places where cars are parked for extended periods (more than an hour), such as homes, workplaces, public parking lots, or roadside parking. Since charging usually takes several hours, it is not suitable for long-distance travelers in a hurry.  Common power include 3.5kW, 7kW, 11kW, and 22kW. Some products now offer higher power, but they come with higher costs and electrical requirements.   As a renowned china charging plug manufacturer, Workersbee's AC charging products have always been popular. This includes charging connectors, charging cables, charging sockets, and portable EV chargers.   In particular, portable EV chargers come in a diverse range of products, including those with screens and without, single-phase and three-phase charging products. These products have been extensively validated in the market over the years, boasting very stable reliability, over 99.9% compatibility, user-friendly smart charging management, and outstanding outlook designs. The impressive market performance further confirms their high performance, high standards, and high reliability.    DC Charging uses a High-power charger (HPC) to draw alternating current (AC) from the grid, which is then converted into direct current (DC) by internal inverters and supplied to the EV's battery. Because the power modules handle substantial amounts of energy, DC chargers are typically larger and have higher procurement, installation, and maintenance costs, with greater electrical requirements.  Since DC power can directly supply large amounts of energy to the EV battery, reducing energy conversion losses within the vehicle, DC charging is highly efficient and fast, significantly reducing charging time. These features make DC charging ideal for public charging stations where vehicles have short stays and for highway corridors for long-distance travel, where there is ample space and convenient electrical distribution. Drivers need not worry about long charging times; a quick restroom break or a cup of coffee is usually enough to provide sufficient charge for their journey. But why doesn’t everyone always prefer fast charging? The charging cost is higher.  For charging station operators, the initial investment is substantial, including equipment, electrical upgrades, and site development, along with high ongoing maintenance costs, all of which are passed on to the drivers.  Additionally, frequent use of fast charging may potentially degrade the vehicle’s battery life time. Furthermore, some vehicles might not support fast charging despite the desire for high efficiency.   Consumers still look forward to safe and stable high-power fast charging in the future. Workersbee's STAR product, the CCS2 liquid-cooled charging plug, has achieved a peak current of up to 700A, while the CCS2 naturally cooled plug offers a continuous current output of 375A.

The electric vehicle revolution has swept the world, and those who are the first to take advantage of it have gained an experience never before experienced in driving a fuel vehicle. Thanks to the instant torque of battery power, electric vehicles start and accelerate faster and are more responsive. Compared with traditional complex internal combustion engines, the electric motors of electric vehicles are simpler, so the control feeling is more stable and precise. In addition, EVs produce almost no noise when driving, making the driving experience more peaceful and comfortable. So, if anyone asks them about the driving experience, these drivers who have switched to EVs will tell you: It’s COOL! However, if you then ask about the unavoidable charging experience, many people may hesitate. That's it, even though electric cars have gained a large number of fans because of their driving experience, electric car charging has always struggled to gain high recognition. This can be sensed from the satisfaction surveys sponsored by many utilities or charger companies. In the final analysis, here are 5 main factors that consumers really consider regarding EV charging.  1.Charging Speed Consumers hope that the speed (time) of charging an EV is as fast as refueling a gasoline car - this is a direction that both charging technology and EV technology need to strive for. We need to understand one fact: charging speed is related to both the charging infrastructure and the charging capacity of vehicles. It's not enough to achieve fast charging with just one of them. High-power DC fast chargers are favored by EV owners because they can output large amounts of power in a short time. Especially during long-distance travel, less waiting time undoubtedly encourages them. As a pioneer China charging cable factory, Workersbee actively caters to market demand.

The number of chargers is far below people's needs, meaning coverage is not ideal. Surveys of electric vehicle charging habits show that charging may occur at High-power chargers (HPC) on highway corridors, curbside chargers in streets, chargers in public or workplaces, and a large portion at home. Workersbee's Portable Electric Vehicle Chargers, whether it's the screen-equipped FLEX CHARGER, ePORT, DuraCharger, or the screenless Soapbox series, have received high praise from car owners due to their high compatibility, lightweight, stylish appearance, and intelligent operation.   In addition to requiring available and accessible chargers, drivers need a platform that can quickly find available chargers when their battery levels are low. This may require the joint efforts of maps or various charging network providers. 3.Charging Safety The safety of the electric vehicle charging process involves multiple aspects. Consumers expect charging equipment to have high safety standards, with the charging system being safe, reliable, and stable. Ensuring that various safety issues such as leakage and fire do not occur during charging. At the same time, it is necessary to ensure communication between vehicles and chargers to monitor battery status at all times, prevent overcharging, and maintain battery health. This also requires regular maintenance checks of charging stations to ensure the normal operation of each charger. Finally, in the payment process, payment security is crucial. Whether it's through card payments or platform deductions, consumers want station operators to ensure the security of their funds. 4.Charging Cost Compared to the rising cost of gasoline, charging costs are a factor that consumers consider when transitioning to EVs. Owners hope to minimize charging costs while maintaining charging efficiency, thereby reducing the cost of daily driving. This cost includes electricity costs related to electricity prices, charger types, and regions, as well as installation costs for those who want more convenient private chargers. However, there are various ways to help consumers reduce costs. For example, at charging stations with a stable customer base, using store value or offering tiered pricing discounts. Or, using utility time-of-use rates to encourage drivers to charge during off-peak hours, avoiding overload pressure during peak periods. You can also provide bonuses to consumers more loyal to the brand, to increase long-term engagement. Shared Chargers can be installed in residential areas with concentrated residents to share installation costs. 5.Compatibility With the continuous growth of the electric vehicle market, various charging standards also have their supporters. Different brands and models of vehicles may require different standards and specifications for charging facilities.

In Europe, the construction of charging infrastructure never stops. The common ones are non-tethered cable chargers. They are usually shown on charging maps as BYO chargers (Bring Your Own), which means drivers need to use their charging cables. On the surface, it seems like drivers need to prepare more. But in reality, this method is more flexible and free and improves the connection opportunities between the vehicle and the charger (the charger can match the cars with different inlets). For charging station operators, investment and maintenance costs are reduced, allowing more funds to be invested in the new chargers. More importantly, as a key part of sustainable transportation, this method is more environmentally friendly.   Learning more about EV charging cable for public charging stations will go a long way toward actively embracing electric vehicles. EV Charging Cable is designed to safely transport power from the charger to the EV, shouldering the important tasks of communicating, controlling, protecting, and transmitting power. The electric vehicle charging cable has four modes, among which Mode 3 connects the vehicle to the charging port of the AC charger. Some charging stations have tethered cables, and some are untethered--You need to carry a charging cable that matches the vehicle socket.     Depending on the vehicle, the plug types are type 1, type 2, and GB/T.   Type 2 To Type 1 The Type 1 end connects to the vehicle and the Type 2 end connects to the charger, which is suitable for electric vehicles with a Type 1 inlet. Support single-phase AC power can provide power output up to 7.4kW, and the maximum current can reach 32A. For North American, Japanese/Korean models, having such a charging cable means you can freely charge EVs at various public charging stations or wall boxes. Of course, if there is a need for fast charging, then DC charging may be more suitable. Because DC Fast Charging Cables need to transmit larger currents, they are often thicker and heavier than Level 2 Charging Cables (AC), so they are tethered to the charger. When facing a high-power DC charger and only a CCS2 connector is available at the charging station, the driver does not have to be frustrated if a CCS2 to CCS1 adapter is available.     The CCS2 to CCS1 adapter from Workersbee, an EV charging cable supplier, can easily connect different standard chargers and electric vehicles, and meets the needs of fast charging, providing a high current of up to 150A. The terminal temperature rise test is less than 50K, the protection level can reach IP54, and it has passed CE certification. The cable is made of TPU for flexibility and durability, adding more opportunities for charging accessibility.   Type 2 To Type 2 Suitable for type 2 vehicles. Available in single-phase 7.4kW, and three-phase 11kW and 22kW. The charging efficiency of an electric vehicle also depends on its onboard charger's charging capacity and the charger's power. As a classic example, if you use an 11kW (16A) cable and choose a 22kW charger to charge an electric car, but your car is single-phase, you will only get 3.7kW of power. It's more like the Cannikin Law. Therefore, the selection criteria for the power of the cable depends more on your car.   Workersbee has developed multiple generations of type 2 ev charging cable products. From the Gen1.0  to the latest Gen2.3, the R&D team has consistently focused on technological innovation and improving user experience.     From terminal rubber covered to ultrasonic welding, from cable management optimization to dustproof, moisture-proof, and waterproof “Smart Cap” design, each iteration not only improves the looks of the products but also makes a leap in the charging experience. The newly launched EV charging cable 2.3 adopts a double protection design. In addition to the terminal parts, the cable tail sleeve is also rubber-covered. The protection level reaches IP55, waterproof and anti-bending, with a longer service life. The new cable management solution also takes portability and storage friendliness to a new level. It has passed TUV/CE/UKCA certification. The cable length can be customized. We provide 5m, 7m, and 10m ev charging cable options, or customized according to your requirements. With the same cable length, a 22kw ev charging cable is heavier than a 7kW one.   Type 2 To GB/T As China's EVs gradually gain more seats in the market, the demand for GB/T connectors is also increasing. Similarly available in single-phase and three-phase options, with a maximum power of 22kW. Although the GB/T connector is similar to the Type2 connector, they are almost opposite. Therefore, the plugs connecting the car and the charger are both male. This is very different from type 1 and type 2 car models.   Market Insights · Detachable cables are widely used in the European market, which greatly improves the flexibility and reliability of driver charging and reduces the risk of damage to fixed cables. North America is still in the early stages of development and may become the future development direction. · Cable length is a double-edged sword. A longer cable means heavier, making it more difficult to carry and store; but it can also mean more flexible charging. If it is a 10m ev charging cable (or 15m or more), then you may not need to worry about the distance between the car's charging inlet socket and the charger outlet socket when you stop to charge. · As a frequently used charging product, durability is a major feature standard in the market. From plug connectors and cables to often-bent cable tails, it is a major test of the manufacturing capabilities of EV charging cable supplier. · Recommending the right electric vehicle charging cables based on consumer needs to obtain the best charging performance is critical to improving the user experience of EVs. Fully understanding the match between cable length, material, electrical parameters and other information and consumer needs will make your business better.   Conclusion As the main part of the European charging market, EV charging cables connect vehicles and chargers. EV Charging Connector Types at one end of the vehicle depend on the vehicle charging port type. It can be divided into type1, GB/T, and type2, respectively suitable for North American/Japanese/Korean models, Chinese models, and other models in Europe. With a professional R&D team, solid production capabilities, and testing, Workersbe is constantly committed to providing consumers with high-quality and reliable charging cables and promoting the development of the electric vehicle charging industry.
