Problems solved by technology

The cells located at the edge of the array dissipate heat faster, while the cells located in the center of the array dissipate heat slowly, or even fail to dissipate heat effectively, so that the central cell of the cell assembly reaches the thermal protection temperature of the cell as soon as possible Value, thereby triggering the protection mechanism of the battery pack, the circuit board controls the battery pack to stop discharging, which affects the normal use of the battery pack and reduces the user experience

Abstract

The invention provides a battery pack, which comprises a cell assembly and a heat dissipation component, wherein the cell assembly comprises a cell array and a gap arranged in the cell array; the cellarray is formed by arranging a plurality of cells in sequence; the gap is enclosed by N cells; N is greater than 2; the heat dissipation component comprises a heat absorption element arranged in thegap; the heat absorption element comprises N side walls; and the N side walls are propped against the side walls of the N cells separately. Compared with the prior art, the battery pack provided by the invention has the advantages that the battery pack assists the cell assembly in heat dissipation through the heat dissipation component, so that the temperature of various regions of the cell assembly can be relatively balanced, the working time of the cell assembly can be effectively prolonged and the decay rate of the cell assembly is reduced, thereby effectively prolonging the service life ofthe battery pack.

Description

technical field [0001] The invention relates to a battery pack. Background technique [0002] A battery pack generally includes a casing, a cell assembly disposed in the casing, and a circuit board for controlling the charging and discharging state of the battery pack. In order to make the battery pack waterproof, the battery cell assembly is usually placed in a closed space. However, during the use of the battery pack, the battery cell assembly will continuously release heat. When the temperature of the battery cell assembly reaches the thermal protection temperature value of the battery cell, the battery pack will stop discharging under the control of the circuit board. [0003] Existing battery cell assemblies usually consist of several battery cells forming an array. The cells located at the edge of the array dissipate heat faster, while the cells located in the center of the array dissipate heat slowly, or even fail to dissipate heat effectively, so that the central ...
