Embodiment 1

[0037] A removable battery module, refer to figure 1 , which includes a battery 3, and a plurality of batteries 3 are arranged to form a battery pack in a manner that the axes are parallel and the polarity directions are consistent. The busbar 1 and the positive busbar 4 are in contact with the positive conductive end of the battery 3, and the negative busbar 1 is in contact with the negative conductive end of the battery 3, so the 12 batteries 3 of the same battery pack are connected in parallel.

[0038] refer to figure 2 and image 3 , the positive bus piece 4 is provided with an elastic member in contact with the positive conductive end of the battery 3 , the elastic member in this embodiment is a spring 41 or an elastic probe 42 .

[0039] refer to figure 1 and Figure 4 , the negative busbar 1 includes a base plate 11, and the base plate 11 is provided with a plurality of limiting guide seats 12 for contacting with the negative conductive end of the battery 3; If t...

Embodiment 2

[0043] A battery system using the battery module in Embodiment 1, refer to Figure 6 , which includes a battery box 7, and the battery box 7 is provided with a battery slot 8 and a cover that cooperate with each other; wherein, the negative busbar 1 and the battery pack are embedded in the battery slot 8, so that the positive pole of the battery pack faces upward, and the positive pole The busbar 4 is connected to the cover.

[0044] refer to Figure 6 and Figure 7 , the cover includes a cover cover 91 and a cover clip 92 for clamping the positive bus piece 4 therein. There are several position-limiting protrusions 922 that can be embedded in the gaps of the battery pack, and the spring 41 is located in the position-limiting groove 921 after passing through the cover clamp 92; the position-limiting groove 921 cooperates with the position-limiting protrusion 922, and the The positive end acts as a limiter, thereby ensuring the stability of the battery pack.

Abstract

The invention discloses a detachable battery module and a system thereof, and relates to the technical field of chemical energy storage. The invention aims at solving the problem that a battery pack is inconvenient to maintain, replace and replace single batteries in a welding mode. According to the technical scheme, the battery module comprises batteries, and the batteries are arranged in a modethat axes are parallel and polarity directions are consistent to form the battery pack; a positive electrode confluence piece is matched with the battery pack, and an elastic piece in contact with thepositive electrode conductive end of the battery is arranged on the positive electrode confluence piece; a negative electrode confluence piece is matched with the battery pack and is provided with alimiting flow guide seat which is in contact with the negative electrode conductive end of the battery; the battery is connected with the limiting flow guide seat in a clamping and embedding manner; when the battery is reversely inserted, the positive conductive end of the battery is not in contact with the limiting flow guide seat. According to the invention, the single batteries can be quickly disassembled and replaced, the normal work of a battery system is not influenced, and short circuit caused by reverse insertion of the batteries can be avoided.

Description

technical field [0001] The invention relates to the technical field of chemical energy storage, more specifically, it relates to a removable battery module and its system. Background technique [0002] In current energy storage systems, multiple small-capacity batteries are usually combined in series and parallel to form a large-capacity high-voltage battery pack, and the positive and negative electrodes of the batteries are usually connected by welding. However, the welding method is inconvenient for the maintenance and replacement of the single battery. Contents of the invention [0003] In view of the deficiencies in the prior art, one of the objectives of the present invention is to provide a replaceable battery module, which has the advantage of convenient replacement of single cells. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A removable battery module comprising: [0006] A battery, wherein a p...
