Abstract

The invention discloses a capacity balancing manager for a storage battery pack, and mainly solves a problem that the voltage real-time changes of the storage battery pack in a power supply process causes the imbalanced power supply of the storage battery pack in the prior art. The manager comprises an STM32 single-chip microcomputer, an ADC collection voltage module connected to the STM32 single-chip microcomputer, an internal resistance measurement circuit connected to the STM32 single-chip microcomputer, a relay switching circuit connected to the STM32 single-chip microcomputer, a display circuit connected to the STM32 single-chip microcomputer, a relay switching circuit connected to the STM32 single-chip microcomputer, and a power supply circuit for supplying power to the STM32 single-chip microcomputer. According to the above technical scheme of the invention, the method achieves the quick and accurate capacity detection and charging and discharging maintenance of the storage battery pack, greatly improves the utilization efficiency of the battery pack, greatly prolongs the service life of the battery pack, and is very high in practical value and popularization value.

Description

technical field [0001] The invention belongs to the field of charging and discharging batteries, and in particular relates to a storage battery group capacity equalization manager. Background technique [0002] With the extensive application of portable power supplies, related detection and maintenance technologies have also been flourishing. Due to the real-time changes in the voltage of the battery pack during the power supply process, the unbalanced power supply of the battery pack is caused. Due to the performance difference of the single cells during the use of the battery pack, the capacity difference in the long-term charge and discharge process continues to increase, which eventually leads to Lead-acid battery pack performance drops dramatically and it shortens cycle life. In many electrical fields, in order to improve battery efficiency and delay battery loss to the greatest extent, a large number of experts and engineers have developed related maintenance technolo...
