The electric automatic air-conditioning (EAAC) could provide good performance by the thermostat AAC controller according to the preset temperature and the vehicle environment conditions by varying the operating parameters of the AC system. Therefore, the EAAC system can simultaneously meet the passenger comfort requirement and the energy-saving performance.

1.AC system component specification calculation based on vehicle dimension, environment conditions and system performance requirement.
2.AC system thermal load estimator and thermostat controller(|ΔT|<±2℃)
2.EAAC driver: Operating voltage: 60~400V, Operating current < 20A, System failure protection: Over-current, over-temperature, Other function: 15V DC/DC converter, embedded control chip, CAN

Electric vehicle air-conditioning system, vehicle thermal management system

The thermostat control algorithm could provide energy-saving and stable cabin temperature for the vehicle.
