Thermal Management
Maintaining optimal operating temperatures for the battery, power electronics, and cabin is critical for EV performance, safety, and range, but these thermal systems must be highly efficient to avoid draining the battery.
We offer a comprehensive suite of highly integrated, efficient motor controllers for pumps, fans, flaps, valves, e-compressors and PTC Heaters, alongside precise sensors for monitoring system temperature and pressure.
By optimizing thermal performance, our solutions ensure component longevity, enable faster charging, extend driving range, and provide a comfortable, quiet cabin—all without compromising the vehicle's critical energy budget".
