Air conditioning for new energy vehicles 2023-09-28

(1) Air conditioning system control strategy

The refrigeration system of new energy vehicle air conditioners is basically the same as that of traditional internal combustion engine vehicles. The heating supply has structural differences according to the means of generating heat sources. The biggest difference is that the mechanical air conditioning compressor driven by the engine is replaced by a high-voltage electric one. Driven electric air conditioning compressor.

(2) Air conditioning system and air conditioning controller

The air conditioning controller of new energy vehicles is not much different from that of conventional internal combustion engine vehicles in terms of structure, cooling and heating control strategies. However, due to the use of electric air conditioning compressors and non-water heating devices, some models provide a New function "Parking air conditioning mode".

The driver can control the temperature inside the cabin through the remote control or timer, and the parking air conditioning mode has nothing to do with the selected driving mode. In parking air conditioning mode, the air conditioning cannot be controlled via the operating elements. The LED of the AC key lights up and the keys are temporarily unavailable. When the vehicle is ready for driving, the parking air conditioning mode is switched off and the air conditioning can be controlled via the operating elements in the vehicle.
