Abstract

The invention relates to the field of hybrid electric vehicle air conditioners and discloses a hybrid electric vehicle air conditioning system. The hybrid electric vehicle air conditioning system comprises a range extender cooling circuit, a heating circuit and a controller. The heating circuit communicates with the range extender cooling circuit through a first electromagnetic valve. The heatingcircuit further comprises an electric heater used for heating cooling liquid of the heating circuit. The system further comprises a temperature sensor. The controller is used for controlling the firstelectromagnetic valve to be opened and closed and the electric heater to be turned on and off according to the temperature detected by the temperature sensor. The invention further discloses anotherhybrid electric vehicle air conditioning system and a control method. An air conditioner controller and a VCU in the system are clear in responsibility, a heat management system effectively operates through a CAN control function, and a compartment and a high-voltage battery are both in the reasonable temperature environment.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicle air conditioning, in particular to a hybrid electric vehicle air conditioning system and a control method thereof. Background technique [0002] According to the development plan of energy-saving and new energy automobile industry, national policies to reduce emissions will affect the development trend of new energy logistics vehicles, and loose local policies will affect the production, sales, promotion and application of new energy logistics vehicles. Light logistics and home delivery have become the largest market for new energy logistics vehicles . [0003] Since the high-voltage battery is the main component of the new energy vehicle, the high-voltage battery is used in a temperature environment of 20-35°C, and the service life and capacity are the largest. How to activate the high-voltage battery with greater activity so that the battery can provide a greater amount of power...
