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 of a storage battery and a method, a device and a storage medium thereof. The method is applied to the battery management module of the storage battery, and includes: acquiring the charging and discharging time of the storage battery in normal operation; judging whether the charging and discharging time reaches a preset activation time cycle; if so, control the battery to perform self-activation and internal resistance detection; obtain the activation time of the battery for self-activation, as well as the discharge current and discharge voltage of the battery at each moment within the activation time; according to each discharge current and discharge voltage, determine Internal resistance of the battery; according to the internal resistance and activation time of the battery, determine the current state of the battery. The invention can control the battery to perform self-activation and internal resistance detection, avoids the influence of the operation of the smart grid due to manual detection, simplifies the battery management method, and improves the work efficiency of the smart grid operation and maintenance personnel.

Description

technical field [0001] The present invention relates to the field of battery intelligent management, in particular to a battery management module of a storage battery and a method, a device and a storage medium thereof. Background technique [0002] With the continuous development of smart grid, the investment in smart terminal equipment is increasing. Using smart terminals can effectively monitor the operation status of the entire smart grid. The battery is the main component that provides backup power for intelligent terminal equipment. [0003] In the prior art, the management and monitoring of the battery usually use a battery management module. The management module can set the required voltage, current range, charging and discharging time of the battery, and control the external power supply to supply power to the battery. However, the self-activation performance test and internal resistance test of the battery itself are not involved, and the test can only be perfor...
