Temperature regulating system of in-vehicle battery

A temperature regulating method of an in-vehicle battery of a vehicle, wherein the vehicle includes a heat exchanger;

• an in-vehicle air conditioner provided with an air conditioner vent, a first air duct formed between the air conditioner vent and the heat exchanger, and a first fan disposed in the first air duct corresponding to the heat exchanger;
• a semiconductor heat exchange module having both a heating end and a cooling end, provided with a second air duct formed between the cooling end of the semiconductor heat exchange module and the first fan, and a third air duct formed between the cooling end of the semiconductor heat exchange module and a compartment;
• a battery thermal management module connected to the heat exchanger to form a heat exchange flow path;
• and a controller connected to the semiconductor heat exchange module, the battery thermal management module, and the in-vehicle air conditioner, wherein a fourth air duct is formed between the air conditioner vent and the compartment, and the in-vehicle air conditioner further comprises a second regulating valve and a second fan that are disposed in the fourth air duct, the method comprising:
• obtaining, by the controller, a required power of the in-vehicle battery when heat exchange needs to be performed on the in-vehicle battery;
• obtaining, by the controller, an actual power of the in-vehicle battery;
• and
• controlling, by the controller and according to the required power and the actual power, at least one of the in-vehicle air conditioner and the semiconductor heat exchange module to operate to regulate a temperature of the in-vehicle battery.
