The present disclosure discloses a temperature adjustment method and a temperature adjustment system for a vehicle. The temperature adjustment method includes the following steps: obtaining a required power used for performing temperature adjustment on a battery; obtaining an actual power used for performing temperature adjustment on the battery; and adjusting an opening degree of an intra-vehicle cooling branch and an opening degree of a battery cooling branch according to the required power, the actual power, an intra-vehicle temperature, and an air conditioner set temperature.

Temperature adjustment method and temperature adjustment system for vehicle

A temperature regulating system of an in-vehicle battery is disclosed in the present disclosure. The system includes: a heat exchanger; an in-vehicle air conditioner, where the in-vehicle air conditioner is provided with an air conditioner vent, a first air duct is formed between the air conditioner vent and the heat exchanger, a semiconductor heat exchange module, where a second air duct is formed between a cooling end of the semiconductor heat exchange module and the first fan, and a third air duct is formed between the cooling end of the semiconductor heat exchange module and a compartment; a battery thermal management module, where the battery thermal management module is 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.

Temperature regulating system of in-vehicle battery

The present disclosure discloses a temperature adjustment method including: obtaining a required power for temperature adjustment on a battery; obtaining an actual power for temperature adjustment on the battery; and adjusting a temperature of the battery according to the required power for temperature adjustment and the actual power for temperature adjustment. The present disclosure may precisely control a temperature adjustment time of the battery, and the actual power for temperature adjustment on the battery is adjustable in real time, so that a heating power and a cooling power of the vehicle-mounted battery may be precisely controlled according to an actual status of the vehicle-mounted battery, thereby adjusting the temperature of the vehicle-mounted battery when the temperature is excessively high or excessively low, maintaining the temperature of the vehicle-mounted battery within a preset range, and avoiding a case of affecting performance of the vehicle-mounted battery because of the temperature.
