Problems solved by technology

However, the existing battery series balance technology is limited to the overall balance of the battery pack, and has poor scalability; the battery parallel balance technology only uses wires to directly realize the parallel connection of batteries
[0004] Therefore, there is a need for a new method that can improve the tolerance between unit cells, and protect each unit cell from charging and discharging, so as to avoid damage to the battery due to overcharging or overdischarging, and affect the use of the battery pack.

Abstract

The invention discloses a battery device which comprises a plurality of battery packs connected in series and in parallel, wherein each battery pack comprises a plurality of batteries, a plurality of batteries are connected in parallel to form a battery group, and a plurality of battery groups are connected in series to form a battery pack. By the invention, the voltage and the capacity of the battery device can be freely configured, and the harm caused by the capacity degradation of single battery to the battery device can be prevented.

Description

technical field [0001] The present invention relates to battery technology, in particular, to a battery device. Background technique [0002] Based on the current power battery technology and manufacturing process level, the performance difference between single batteries exists objectively throughout their life cycle, which leads to the unbalanced capacity of one or several batteries in the secondary battery pack. Affect the performance of the entire battery pack, and in severe cases may cause the entire battery pack to collapse. For example, in a large battery pack, many small unit cells are required. Due to the differences in capacity and various performances caused by the power battery technology and manufacturing process level, it is easy for the battery pack to cause damage to certain batteries during use. Overcharge or overdischarge, and some batteries will be undercharged or underdischarged, which will cause the difference between the unit cells to become larger and...
