EV Parts - The Growing Demand for Electric Vehicle Thermal Management Solutions
With the rapid growth of the global electric vehicle market, the demand for EVs is rising. and expected to reach $1.4 trillion by 2025. However, as EV adoption increases, the risks of inadequate battery thermal management become apparent. Studies show that every 10°C rise in temperature reduces battery life by about 50%.
Without proper thermal management, overheating and temperature imbalances can occur, reducing efficiency and posing safety risks. In the future, optimizing temperature control is critical for the safety and longevity of next-gen EVs with a higher complex design, energy efficiency, and longer lifespan.
Liquid Cooling Plates Technology
Liquid Cooling Plates work by circulating coolant through internal channels, drawing heat away from the battery pack. As batteries generate heat during charging or driving, excessive heat reduces efficiency and shortens lifespan.
Studies show that battery life decreases by 50% for every 10°C increase in temperature. Liquid Cooling Plates maintain optimal temperatures, preventing overheating, enhancing battery life, and improving overall EV performance.
Blowing Type Heat Cooling Plate
The blowing type heat cooling plate typically works by dispersing heat via airflow or coolant. The plate is designed to maximize surface area for heat transfer. It works in combination with forced air or liquid systems to efficiently spread the thermal load across the battery pack or other electronic components.
Heat Conduction Speed: More faster than 340m/s
Operating Temperature Range: Below -40°C
Heat Conduction Mode: Two or three-dimensional
Material: Aluminum Alloy
Application: EVs, eVTOL
Heat Conduction Temperature: Below 2°C
Flow Rate Control: ±0.5g
Technology: Patented Vacuum Infusion Technology
Hydroformed Liquid Cold Plates
Hydroformed Liquid Cold Plates are created through a hydroforming process, where high-pressure water is used to mold metal sheets (typically aluminum or copper) into complex shapes. This method allows the creation of highly efficient cooling channels within the plate, which are critical for effective heat dissipation. The process also ensures that the cold plates maintain uniform thickness and strength, essential for long-term performance in demanding environments.
Operating Temperature: -40°C and +150°C
Material: Aluminum or Copper
Application: EVs, ESS, Solar, eVTOL
Technology: Hydroforming Technology
Copper Tube Heatsink
Copper tube heatsinks use the aluminum and copper tube to quickly transfer and dissipate heat, ensuring a minimal gap between the heat pipes and the heatsink, reducing conductive thermal resistance caused by any gaps.
Operating Temperature: 0°C to 150°C
Material: Aluminum and Copper
Application: IGBTs, EVs, eVTOL
Technology: Heatpipe Cooling Technology
Extruded Cold Plate
Extruded Cold Plates are made from high-quality aluminum alloys using an extrusion process that creates internal cooling channels. This manufacturing method offers the flexibility for customization with a cost-effective price.
Operating Temperature: -40°C to +150°C
Material: Aluminum Alloy
Application: EV, ESS, Heavy Vehicle
Technology: Aluminum Hot Extrusion
FSW Cooling Plate
Friction Stir Welding Cold Plates is an advanced welding technology that joints different materials, reducing the risk of thermal resistance at the joints and providing excellent strength.
Operating Temperature: -40°C to +150°C
Material: Aluminum Alloy, Copper, or Custom Combinations
Application: Marines, Heavy Vehicle
Technology: Friction Stir Welding Technology
Vapor Chamber Technology: Boost EV Battery Efficiency and Longevity
The vapor chamber heatsink utilizes phase change heat transfer technology. The working fluid inside the cavity evaporates in the heating area and then moves to the cooling through micro-channels, where the steam condenses and releases heat. Phase change heat conduction has good isothermal properties, and the internal temperature can be known by measuring the external temperature of the battery pack using phase change heat conduction technology.
The temperature measurement is simpler and more convenient for detecting faults. Therefore, this solution is particularly suitable for electric vehicle (EV) battery packs, which can extend battery life by 30%-40% and has a high thermal conductivity of up to 8,000-200,000W/m·K.
Soft Pack Battery Liquid Cooling Heat Exchange System
The system consists of a phase change thermal conduction system, liquid cooling plates, coolant circulation pipes, battery modules and housing. The phase change thermal conduction system transfers the heat generated by the battery to the liquid cooling plates, and the coolant circulating within the plates carries the heat away, ensuring stable battery temperature.
The soft pack battery liquid cooling system is designed for EVs battery systems. It provides precise and efficient temperature control, especially under prolonged high-load operation, maintaining the battery’s working temperature between 30°C and 40°C, which significantly extends battery lifespan.
Cylindrical Battery Air Cooling System
The System is a thermal management solution designed for electric vehicle (EV) battery systems, particularly suitable for medium to low power EVs and electric bicycles. The battery cells are mounted between the phase change system slopes, which helps maintain balance during vehicle operation. It consists of cylindrical battery cells, battery housing, heat fins, and a phase change system.
The curved phase change heat fins transfer the heat released by the battery to larger heat fins, which are then cooled by forced convection generated during vehicle movement. This solution provides temperature control through simple air cooling, with a robust structure and low cost, making it ideal for applications where high-precision temperature control is not required.
Extruded Aluminum End Plate - the ideal solution for EV Thermal Performance and Structural support
The aluminum end plate is a crucial component in EV battery packs, designed to provide both structural support and efficient thermal management. Manufactured from high-strength aluminum alloys, the end plate ensures the battery cells are securely housed and protected during vehicle operation.
With high thermal conductivity and precision structure, EV end plate can improve the thermal efficiency of the battery pack by 20%-30%, leading to an extended battery lifespan of 10%-15% because it minimizes thermal stress on the battery cells. Meanwhile, the lightweight design contributes to the overall energy efficiency of the vehicle.
