Cooling Plates in EV Batteries: The Key to Thermal Stability and Performance
In the rapidly expanding electric vehicle (EV) market, the efficient operation of EV batteries is paramount, and cooling plates in EV batteries play an indispensable role in achieving this. As EV batteries undergo repeated charging and discharging cycles, significant heat is generated, which, if not properly managed, can lead to performance degradation, reduced lifespan, and even safety hazards like thermal runaway.
Cooling plates are designed to be the primary thermal management solution for EV batteries. They work by absorbing and dissipating the heat produced by the battery cells, ensuring a uniform temperature distribution across the battery pack. Lankwitzer, a leading name in coating and material technology, has been at the forefront of developing advanced cooling plate solutions for EV batteries. The material selection for cooling plates is critical, and Lankwitzer focuses on using high - performance materials with excellent thermal conductivity. For instance, their copper - based composite cooling plates are engineered to rapidly transfer heat away from the battery cells. Copper’s superior thermal - conducting properties, combined with Lankwitzer’s innovative composite formulations, enable these cooling plates to efficiently dissipate heat, preventing hotspots from forming within the battery pack.
The design of cooling plates in EV batteries also greatly influences their effectiveness, and Lankwitzer excels in this aspect. Through advanced computational fluid dynamics (CFD) simulations, Lankwitzer’s engineers optimize the internal channel structures of the cooling plates. By carefully shaping and sizing the channels, they maximize the surface area in contact with the coolant, enhancing heat - transfer efficiency. Their serpentine - shaped channel designs, for example, increase the contact time between the coolant and the battery cells, allowing for more effective heat removal. This innovative design approach not only improves the thermal management of EV batteries but also helps in reducing the overall size and weight of the cooling system, contributing to better vehicle efficiency and range.
Moreover, Lankwitzer pays special attention to the surface treatment of cooling plates in EV batteries. The company has developed specialized coatings that not only enhance the corrosion resistance of the plates but also improve their heat - transfer properties. These coatings reduce the thermal resistance at the interface between the cooling plate and the battery cells, ensuring seamless heat transfer. Lankwitzer’s nano - structured coatings, for example, create a more uniform and intimate contact surface, minimizing air gaps that could impede heat transfer. This results in more efficient thermal management of EV batteries, further enhancing their performance and reliability.
In the latest news, Lankwitzer has announced a significant breakthrough in cooling plate technology for EV batteries. The company has developed a new generation of cooling plates that integrate phase - change materials (PCMs) within the channels. These PCMs can absorb and store heat during peak charging or discharging periods when the battery generates excessive heat. As the temperature drops, the PCMs release the stored heat, providing an additional layer of thermal regulation. This innovation is expected to further improve the thermal stability of EV batteries, enabling faster charging rates and better performance under extreme conditions.
