Service Background
Low-altitude aircraft such as eVTOL electric vertical takeoff and landing aircraft and drones, due to their aviation application scenarios and the high-efficiency heat dissipation requirements of batteries and motors, also require thermal management systems to accurately regulate the operating environment temperature of batteries/motors. During flight modes such as takeoff and landing, eVTOLs need to provide high power output from the battery for a short period of time, placing extremely high demands on thermal management in various application modes. Furthermore, the aircraft needs to maintain battery operation within its suitable temperature range under various high-temperature or low-temperature application scenarios, requiring the thermal management system to provide corresponding temperature control strategies. Effective performance verification of the thermal management system's thermal management performance, environmental reliability, and control management system is achieved through heat exchange performance testing, high and low temperature cooling and heating performance testing, and environmental reliability testing.
