Battery box

Abstract

The invention relates to a battery box. The battery box comprises a battery box body as well as a plurality of battery modules, an electric connecting sheet and a collection bus plate which are received in the battery box body; the plurality of battery modules are arranged successively in an abutting manner; each battery module comprises a battery pack formed by arranging a plurality of single batteries in an abutting manner; each single battery comprises a top surface; the electric connecting sheet is arranged on a plane formed by splicing the top surfaces of the plurality of single batteriesof the plurality of battery modules; the electric connecting sheet comprises a plurality of first electric connecting sheets and a plurality of second electric connecting sheets; the plurality of single batteries in the plurality of battery modules are connected in serial to form a whole body by virtue of the plurality of first electric connecting sheets and the plurality of second electric connecting sheets; the collection bus plate is formed by splicing a plurality of collection unit plates; each collection unit plate is arranged above the corresponding battery module; and the collection bus plate is provided with a receiving hole for accommodating the electric connecting sheet. The interior of the battery box has no connection of wiring harness, so that the internal wire connecting wayof the battery box is simplified.

Description

【Technical field】 [0001] The invention relates to the technical field of power batteries, in particular to a battery box. 【Background technique】 [0002] At present, the electric vehicle industry is developing rapidly, and people's demand for electric vehicles is also increasing. As one of the core components of new energy vehicles, the power battery box has the characteristics of high safety, good cycle performance, environmental friendliness, non-toxic and harmless, and relatively low cost of raw materials, which has attracted people's attention. At present, multiple single batteries in the battery box require various wiring harnesses to realize series-parallel connection and information collection, which makes the wiring inside the battery box complicated and difficult to install and maintain, especially in the daily use process. Friction between firmware or wire harnesses can easily cause damage to the collection and monitoring lines, resulting in short circuits and lim...

AI Technical Summary

Problems solved by technology

At present, multiple single batteries in the battery box require various wiring harnesses to realize series-parallel connection and information collection, which makes the wiring inside the battery box complicated and difficult to install and maintain, especially in the daily use process. The friction between the firmware or the wiring harness can easily cause the problem of damage to the collection and monitoring line, which will cause a short circuit and limit the collection signal

At the same time, the assembly of the battery box is more complicated and consumes a lot of manpower and material resources
