Problems solved by technology

Some of the multiple batteries are directly placed in the battery outer box. Due to the lack of necessary fixing of the battery in this installation method, the electrical contact of the battery is not reliable, and the external vibration can easily affect the state of the battery. The entire battery pack is in a high vibration environment The work stability is very poor; some batteries are tightly fixed together, although this method solves the problem of battery shock resistance to a certain extent, but the multiple batteries are squeezed together, which is not conducive to the heat dissipation of the battery core when it is working. , which also affects the working stability of the battery pack

Abstract

Disclosed is a shakeproof power battery pack device. A bracket structure which limits the positions of a plurality of battery pack units(2) is arranged inside a shell(1); the bracket structure comprises a lower bracket(51), an upper bracket(55) and at least one middle bracket(52) arranged between the upper bracket(51) and the lower bracket(55); a plurality of locating holes(53)or locating semi-holes(56)which are respectively used to clamp the batteries are arranged on the brackets; one battery pack unit(2) is arranged between the lower bracket(51)and the middle bracket(52) and one battery pack unit(2) is arranged between the middle bracket(52)and the upper bracket(55); the battery pack units(2) are vertically stacked into a whole body and are encased in the shell. The batteries of the battery pack are reliably positioned and are of good shake resistance, so the electric cores can have good electric contact and good heat dissipation; therefore the shakeproof power battery pack device is suitable for power battery pack device under vibration conditions.

Description

technical field [0001] The invention relates to a rechargeable power supply device, in particular to a lithium ion battery pack for providing vehicle power supply. Background technique [0002] Existing rechargeable power sources, such as power batteries used in electric bicycles, generally use multiple batteries connected in parallel or in series to expand the capacity of the battery and increase the voltage of the battery. Some of the multiple batteries are directly placed in the battery outer box. Due to the lack of necessary fixing of the battery in this installation method, the electrical contact of the battery is not reliable, and the external vibration can easily affect the state of the battery. The entire battery pack is in a high vibration environment The work stability is very poor; some batteries are tightly fixed together, although this method solves the problem of battery shock resistance to a certain extent, but the multiple batteries are squeezed together, whi...
