Energy storage technology battery grouping system

Abstract

The invention discloses an energy storage technology battery grouping system. The system comprises an outer frame, a battery management module, an inner frame and a battery pack module, wherein a bottom plate is fixedly mounted at the bottom in the outer frame; a mounting shell is fixedly mounted at the top end of a detection base; a battery placement groove is formed in the mounting shell; a single battery pack is mounted in the battery placement groove; and the battery management module is fixedly mounted on one side of the outer frame. According to the energy storage technology battery grouping system, the inner frame is arranged in the outer frame, a battery pack module which can be movably taken is arranged in the inner frame, the use is simpler and more convenient, the battery pack module is conveniently matched with a pressing plate and a mounting connector, the wire is enabled to be away from the battery pack during wiring, and safety hazards are reduced. In the charging and discharging process of the battery pack module, a current equalizer is used for equalizing the current of the battery pack, the BMU receives the information of the battery pack, and when the battery pack modules are inconsistent, the battery pack modules are equalized through the equalizer.

Description

technical field [0001] The invention relates to battery grouping, in particular to a battery grouping system of energy storage technology, which belongs to the technical field of battery application. Background technique [0002] Energy storage is one of the most important enabling technologies of the smart grid, and combining it with renewable energy power generation technology can not only improve system stability, improve power quality, but also improve resource utilization, becoming the current energy technology The standard energy storage battery pack is the basic unit of a large-scale battery energy storage system. The service life of the standard battery pack directly determines the service life of the energy storage system. one of the core technologies. [0003] The battery of the existing electric vehicle is generally composed of multiple independent batteries combined in batches, then welded to form a corresponding series and parallel connection to form a battery ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a battery grouping system for energy storage technology to solve the problem that the battery modules proposed in the above background technology are all integrated inside the frame, which is very inconvenient when it needs to be replaced and taken, and the wires are connected to the outside through The top connection of the frame, the lack of dredging devices, is unsafe to use, and the weight of the assembled battery modules is superimposed. If manual handling is used, it is difficult to operate and more dangerous.
