Advanced and Customized Cooling Solutions for New Energy Vehicle Battery Thermal Management  

As lithium-ion batteries are widely used in new energy vehicles (NEVs), effective thermal management systems are crucial for optimizing performance, range, lifespan, and safety. Battery cells generate substantial heat during operation and charging. High temperatures degrade cells irreversibly, reduce efficiency and pose risks of thermal runaway. Precise temperature control and cooling are required, especially for high-energy, high-power battery packs.

Our company is a leader in developing innovative thermal management solutions for NEV power systems. We offer customized cooling plates, cold plates, heat exchangers and circulation systems for maintaining ideal temperatures from -40°C to 65°C in any environment. Leveraging computational fluid dynamics, our solutions optimize coolant flow, temperature uniformity, and pack efficiency.

For high-performance NEVs, we developed ultra-compact laser-welded cooling plates under 20mm thick. Our solution cools over 1,000 lithium cells generating 800kW of heat with under 2°C temperature differential across the pack. The lightweight, corrosion-resistant plates maximize volumetric energy density and powertrain efficiency.

Liquid-based systems enable precise year-round heating and cooling. We provide coolant circulation systems with onboard heaters, pumps, valves, and programmable controllers that can be seamlessly integrated into existing battery designs.

A global leader utilized our technology in their latest electric supercar. Our solution cools a 60kWh battery pack in the confined engine bay, allowing 15-minute fast charging and high-performance discharges with maximum temperature rise of just 5°C.

For an European bus maker, we developed a modular battery cooling system for different vehicle sizes. It maintains temperatures within 1°C of the setpoint in extreme hot or cold weather, enabling their fleet to have the longest range and battery life of any in-service NEV buses.

Our innovative solutions improve vehicle range, battery longevity, and safety. We partner with automakers, Tier 1 suppliers and battery producers worldwide to deliver custom temperature control for next-generation electric mobility.

In summary, advanced thermal management is essential for high-performance NEV battery packs. Customized cooling solutions with optimized system designs can maximize range, efficiency, and safety through precise temperature control. Our technology is accelerating the transition to more sustainable transportation by fully utilizing the potential of lithium batteries. We will continue boosting capacity and shortening charging times with our innovative power system thermal management solutions.
