Abstract

The present invention relates to the technical field of power battery management. In order to solve the problem of battery damage caused by the temperature rise of the battery during charging, a battery charging management method is provided, which includes the following steps: S1, voltage detection module detection The voltage of the battery module in the battery box; S2. When the voltage detected by the voltage detection module is less than the minimum threshold value pre-stored in the storage module, the charging module charges the battery module; S3. The voltage detection module detects that the voltage of the battery module is greater than the pre-stored threshold in the storage module. After the highest threshold, the charging module stops the charging operation; S4. In S2, the heat dissipation system performs heat dissipation operation on the battery box.

Description

technical field [0001] The invention relates to the technical field of power battery management, in particular to a battery charging management method. Background technique [0002] Vehicle-mounted lithium batteries are power batteries for hybrid vehicles and electric vehicles. Since some technical properties of nickel-metal hydride batteries, such as energy density and charge-discharge speed, are close to the theoretical limit, lithium batteries have high energy density, large capacity, and no memory. Etc. The cost, performance, and life of power batteries determine the cost and reliability of hybrid electric vehicles and electric vehicles to a large extent. [0003] At present, most of the chargers commonly used by consumers charge the battery with a constant current method. This method has strong adaptability and can be used regardless of the voltage of the battery, but it takes a long time to charge. In addition, there are also chargers with fast depolarization and fas...
