Thermal Management

Integrated Controller for Electric Compressor and Heater

The industry's first integrated controller solution for compressors and heaters, supporting independent or simultaneous operation of a 12kW compressor and an 8kW heater. The highly compact hardware design enables centralized management of the vehicle's high-voltage thermal management system while achieving maximum cost efficiency. Features low ripple current of less than 6A and EMC performance compliant with CLASS 3 standards. With an operating temperature range of -40°C to 125°C, it is fully adaptable to pure electric, range-extended, and hybrid vehicle models.
