Problems solved by technology
However, due to the large functions of buses or buses, when the air conditioner is turned on, the battery will generate a lot of heat. In order to ensure the heat dissipation of the battery, an external heat dissipation device is generally equipped to cool the battery. In addition, when the vehicle is running in a cold environment, The performance of the battery will drop rapidly, and it is necessary to heat the battery to ensure its reliable and stable operation. In the prior art, a heating device is specially added to heat the battery. Unified control, complex equipment and difficult maintenance, therefore, it is necessary to design a new control method for air-conditioning battery heat pumps

Description
technical field [0001] The invention relates to a control method of an air conditioner battery heat pump. Background technique [0002] With the country's promotion of energy saving and emission reduction, more and more cars are driven by power batteries. During the operation of the vehicle, it is necessary to turn on the air conditioner when the temperature inside the car is too high or too low. This is common for ordinary passenger buses or buses. have the function. However, due to the large functions of buses or buses, when the air conditioner is turned on, the battery will generate a lot of heat. In order to ensure the heat dissipation of the battery, an external heat dissipation device is generally equipped to cool the battery. In addition, when the vehicle is running in a cold environment, The performance of the battery will drop rapidly, and it is necessary to heat the battery to ensure its reliable and stable operation. In the prior art, a heating device is speciall...
