TEMPERATURE REGULATION SYSTEM FOR VEHICLE-MOUNTED BATTERY

A temperature regulating system of an in-vehicle battery is disclosed in this application. 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. The system can regulate the temperature when the temperature of the in-vehicle battery is excessively high, so that the temperature of the in-vehicle battery is maintained in a preset range, thereby avoiding the situation that the performance of the in-vehicle battery is affected by the excessively high temperature.
