Abstract

The invention provides a battery thermal management system and a battery thermal management method for a vehicle, and belongs to the field of vehicles. The battery thermal management system comprisesthe following parts of a battery; a vehicle control unit for sending a power-on signal when the vehicle is powered on, and sending a power-off signal when the vehicle is powered off; an auxiliary power supply unit, which is electrically connected to the battery and configured to be charged by the battery and store power when the vehicle is powered on; and an auxiliary thermal management system, which is communicatively connected to the vehicle control unit and electrically connected to the auxiliary power supply unit, and configured to be charged by the auxiliary power supply unit and heat thebattery at a preset temperature and a preset time period when receiving the power-off signal. The invention also provides a corresponding battery thermal management method. The battery thermal management system and thermal management method provided by the invention can solve the problems of poor driving experience and short battery life in cold areas.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a battery heat management system and heat management method for vehicles. Background technique [0002] According to research and investigation, the reason why new energy vehicles are not popular in cold regions is because in actual use, if new energy vehicles are parked in the open overnight, the temperature of the high-voltage battery will drop to a temperature close to the room temperature, resulting in a loss of output power of the high-voltage battery. Greatly reduced. [0003] The high-voltage battery system cooled by liquid cooling requires the vehicle thermal management system to heat the coolant first, and then heat the high-voltage battery through the coolant. The disadvantage of this heating is that the heating time is long, and it takes 15 minutes for every 5°C of heating. During the heating process, passengers need to wait in the car, which greatly reduces the driving exper...
