Cooling Plates for EV Batteries: Lankwitzer’s Solutions Ensuring Optimal Performance

In the rapidly evolving electric vehicle (EV) industry, cooling plates for EV batteries have emerged as a crucial component. As the demand for high - performance, long - range EVs surges, the effective thermal management of batteries becomes essential. Cooling plates play a pivotal role in dissipating the heat generated during the charging and discharging processes of EV batteries. This not only prevents overheating, which can lead to reduced battery performance and lifespan, but also enhances the overall safety of the vehicle.

Lankwitzer, a well - known company in the field of battery coatings, has been actively involved in developing advanced cooling plates for EV batteries. At the 3rd eic Three - Electric and Energy Storage “Insulation, Flame Retardancy, Heat Insulation, and Sealing” Technology Conference in 2024, Lankwitzer presented its latest solutions for cooling plates in EV batteries. The company’s representatives emphasized their commitment to developing innovative products that meet the stringent requirements of the EV market.

Lankwitzer’s Evoprotect455UV series, initially developed for battery insulation, has also demonstrated excellent performance in the context of cooling plates for EV batteries. The series features a unique formulation that combines high - quality insulation with efficient heat - dissipation properties. For example, Evoprotect455UV (UE55 - 0500/0), which took three years to develop and entered production in 2018, has a production volume exceeding 4,000 tons and an initial operation pass rate of over 98%. It has been widely applied in cooling plate coating processes in Germany and China, covering more than 500 million battery units.

Evoprotect455UV (UE55 - 0500/7), launched in 2023, further showcases Lankwitzer’s technological prowess. Even after 1,000 hours of 85/85 aging tests, it can still meet customized customer requirements. With a shear strength of over 12mpa, low curing energy, an insulation withstand voltage of more than 6kvdc, and a dielectric strength of over 150kv/mm, this product effectively ensures the long - term stability and reliability of cooling plates for EV batteries.

Lankwitzer’s cooling plate solutions for EV batteries offer multiple advantages. The UV - curing technology enables the coating to solidify in less than 5 seconds, with a production cycle that can reach 50 - 60 ppm. This significantly improves production efficiency and reduces time - related costs. In terms of environmental protection and cost - control, the coatings have excellent recycling performance, with a comprehensive utilization rate of up to 95%. They also generate almost no volatile organic compounds (VOCs) during the curing process, meeting strict environmental standards.

In a practical application scenario, a leading EV manufacturer adopted Lankwitzer’s cooling plate coating solutions. The results showed that the EV batteries equipped with Lankwitzer - coated cooling plates maintained a stable operating temperature even during high - speed driving and fast - charging processes. This led to an improvement in the battery’s overall performance, with a capacity retention rate of over 85% after 5,000 charge - discharge cycles, far exceeding the industry average.

Lankwitzer’s Shanghai Testing Center, equipped with a full - process spraying line, provides customized spraying services for cooling plates. This helps customers save the investment in building a trial - production line and accelerates the implementation of new technologies.

Thanks to its continuous innovation, Lankwitzer has provided cooling plate coating solutions for over 450 million commercial EV battery units. As the EV industry continues to grow, Lankwitzer’s advanced cooling plates for EV batteries will play an increasingly important role in driving the industry forward.
