Quick-change battery and battery case

Abstract

The invention relates to the field of secondary batteries, in particular to a quick-change battery and a battery casing. Wherein, one of the shell walls of the battery shell of the quick-change battery is equipped with a plug for plugging into the charging device or the vehicle body, the plug includes an insulating shell and an electrical contact piece encapsulated in the insulating shell, and the electrical contact The component is electrically connected to the battery core, and the insulating shell and the shell wall where the plug is located are integrally structured. In the quick-change battery of the present invention, the insulating shell of the plug and the shell wall of the battery shell are arranged as an integral structure, so that the connection between the plug and the battery shell is relatively reliable, and secondly, the electrical contact is encapsulated in the insulating shell. , the sealing effect of the plug itself is better, and the integrated structure of the insulating casing of the plug and the battery casing also avoids the connection gap of the detachable connection of the two, and the problem of sealing failure will not occur, so the quick-change battery of the present invention Compared with the batteries in the prior art, the battery has better sealing performance.

Description

technical field [0001] The invention relates to the field of secondary batteries, in particular to a quick-change battery and a battery casing. Background technique [0002] With the rapid development of new energy applications, the proportion of electric bicycles or electric vehicles used for transportation in cities cannot be ignored. Among them, electric bicycles can be divided into plug-in type and power-exchange type according to different charging methods. When charging plug-in electric bicycles, the owner needs to place the whole vehicle in a special charging area for charging, and wait for the charging to be completed before the next ride. The battery-swappable electric bicycle is to ride the whole vehicle with insufficient power to the designated power-swap area, and replace the power battery with insufficient power with the battery that has been charged in the charging cabinet, so the owner can directly download the battery after replacing the battery. One ride sa...
