Electric vehicle battery management system and method for managing power batteries by using same

Abstract

The invention discloses an electric vehicle battery management system and a method for managing a battery by using the same, which can realize the real-time monitoring of the overdischarge of a storage battery and the temperature of a power battery, ensure the normal power supply of the storage battery and reduce the risk that high-voltage kinetic energy cannot be provided. The system comprise a low-voltage power supply module, a high-voltage power supply module and a direct-current transformer DC-DC; a battery management controller BMS is integrated with a power distribution system PDU, an electric heating device and a cooling device are arranged on the outer surface of the power battery, a temperature sensor is electrically connected with the battery management controller BMS, and the battery management controller BMS controls the electric heating device and the cooling device to adjust the temperature of the power battery according to temperature information of the temperature sensor. The battery management controller BMS is in communication connection with a cloud platform through a vehicle machine TBOX, and the method for managing the battery by applying the system comprises astorage battery control management method and a power battery control management method.

Description
