Problems solved by technology

However, the self-activation performance test and internal resistance test of the battery itself are not involved, and the test can only be performed after the battery is artificially removed from the smart grid.
Manual operation not only affects the stable operation of the smart terminal, but also affects the service life of the battery due to the continuous disassembly and assembly of the battery, which increases the operation and maintenance cost of the smart grid and the workload of the operation and maintenance personnel.

Abstract

The invention discloses a battery management module, method and device of a storage battery and a storage medium, the method is applied to the battery management module of the storage battery, and the method comprises the following steps: acquiring the charging and discharging time of the storage battery in normal work; judging whether the charging and discharging time reaches a preset activation period or not; if yes, controlling the storage battery to perform self-activation and internal resistance detection; obtaining the activation time of self-activation of the storage battery and the discharge current and the discharge voltage of the storage battery at each moment within the activation time; determining the internal resistance of the storage battery according to each discharge current and discharge voltage; and determining the current state of the storage battery according to the internal resistance and the activation time of the storage battery. The self-activation and internal resistance detection of the storage battery can be controlled, the influence of manual detection on the operation of the intelligent power grid is avoided, the management method of the storage battery is simplified, and the working efficiency of operation and maintenance personnel of the intelligent power grid is improved.

Description

technical field [0001] The invention relates to the field of battery intelligent management, in particular to a battery management module of a storage battery, a method, a device and a storage medium thereof. Background technique [0002] With the continuous development of the smart grid, the investment in smart terminal equipment continues to increase. Using smart terminals can effectively monitor the operating status of the entire smart grid. The battery is the main component that provides backup power for smart terminal equipment. [0003] In the prior art, the management and monitoring of the storage battery usually use the battery management module. The management module can set the required voltage and current range of the storage battery, the charging and discharging time of the storage battery, and control the external power supply to supply power to the storage battery. However, the self-activation performance test and internal resistance test of the battery itsel...
