Problems solved by technology

However, for series-type and parallel-series battery boxes, the discharge capacity of each level of battery is different during use, so when charging them with the same amount, if they are charged according to the battery with more discharge, discharge will occur. If the battery with less discharge is charged, the battery with more discharge will be undercharged, which will affect the use of the battery box.
Therefore, when using the traditional method to charge the series and parallel battery boxes, it will cause uneven charging, which will affect the service life of the battery box and even damage the battery.

Abstract

An embodiment of the invention provides a cell box charging system and a cell box power system. The cell box charging system comprises switches which are correspondingly connected with each cell pack. The cell box power system comprises a cell box, and switches and binding posts which are correspondingly connected with each cell pack in the cell box. When the cell box charging system is in charging, connection between each switch, the battery pack and an external power supply enables each battery pack which needs charging to form a parallel circuit to carry out charging, battery packs with large and small power consumption can reach uniform charging, and a service life of the cell box is greatly prolonged. Simultaneously, when the cell box power system is in charging, a parallel circuit is formed to carry out charging, charging of the cell box is more uniform, and the service life of the cell box also is greatly prolonged.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a charging system for a battery box and a system for using electricity for a battery pack. Background technique [0002] Whether in daily life or in industrial production, batteries are widely used at present, and single-stage batteries often cannot meet people's needs, so multi-stage batteries are often combined in series, parallel or series-parallel. The form of the battery box, for example, there is a series battery box that connects multi-stage batteries with lower voltage in series to achieve a higher voltage, and there is a parallel-connected battery box that connects multi-stage batteries with a lower current in parallel to achieve a larger required current There are parallel series battery boxes that connect parallel battery packs with lower voltage in series to achieve higher required voltage, and series-parallel battery boxes that connect multiple series battery packs with lowe...
