Problems solved by technology

Some of the batteries are directly placed in the battery box. This installation method lacks the necessary fixing of the batteries, making the electrical contact of the batteries unreliable. External vibrations can easily affect the state of the batteries. The working stability is very poor in a vibrating environment; some cells are tightly fixed together. Although this method solves the problem of shock resistance of the battery to a certain extent, but the multiple cells are squeezed together, which is not conducive to battery life. The heat dis

Example Embodiment

[0022] The following is a further detailed description with reference to the preferred embodiment shown in the accompanying drawings.

[0023] Such as figure 1 with figure 2 As shown, the shock-proof and moisture-proof power battery pack of the present invention includes a casing 1, a plurality of cells arranged in the casing 1, a charge-discharge and charge-discharge protection circuit board 3 electrically connected to the cells 2, and a circuit board 3 for placing And fix the bracket structure 5 of the plurality of cells 2. The support structure 5 fixes each battery core 2 in the axial and radial directions, and keeps a certain distance between the battery cores 2 to facilitate the heat dissipation of the battery core 2 during operation.

[0024] Such as figure 2 As shown, the support structure 5 is formed by joining the upper cover 52 and the lower cover 53 to form a box structure. The upper cover 52 has two front and rear side walls and a top surface. A plurality of radial ...

Abstract

The invention relates to a shock-resistant and damp-proof power battery set which comprises an outer shell (1), a plurality of cells (2) arranged inside the outer shell (1) and a charging/discharging protection circuit board (3) in electric connection with the plurality of cells (2), wherein a support structure (5) constraining the positions of the plurality of cells (2) axially and radically is fixed in the outer shell (1), the plurality of cells (2) constrained in the support structure (5) are arranged with a clearance in between. The cells in the battery set can be positioned reliably to keep a sound electric contact, has very good shock-resistant performance and heat dispersion performance and is very suitable to be used on various power battery sets in shaking circumstances.

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 cells connected in parallel or in series to expand the capacity of the battery and increase the voltage of the battery. Some of the batteries are directly placed in the battery box. This installation method lacks the necessary fixing of the batteries, making the electrical contact of the batteries unreliable. External vibrations can easily affect the state of the batteries. The working stability is very poor in a vibrating environment; some cells are tightly fixed together. Although this method solves the problem of shock resistance of the battery to a certain extent, but the multiple cells are squeezed together, which is not conducive to battery life. The heat dissipation w...
