Abstract

The invention discloses a battery pack. The battery pack comprises a plurality of cells and a temperature regulating module, wherein the temperature regulating module comprises a first flow channel, a second flow channel, and a third flow channel communicated with each other; and the third flow channel is vertically arranged between adjacent cells. The battery pack provided by the invention has the advantages of low energy consumption, good internal thermal balance, uniform overall heat dissipation, simple structure, and the like, and can be widely used in the related fields of electric vehicles, energy storage power stations and the like.

Description

technical field [0001] The invention relates to a battery pack, in particular to a battery pack with a temperature regulating module. Background technique [0002] Lithium-ion power battery packs have been increasingly widely used in related fields such as electric vehicles and energy storage power stations due to their high energy density, high specific power, long cycle life, and large capacity. [0003] For a power battery pack, temperature is a major factor affecting its battery performance and life. To address this problem, a temperature regulation module is generally introduced to adjust the internal temperature of the battery pack under discharge conditions, so that the battery can be operated at a suitable temperature. Work. At present, the temperature adjustment of the power battery pack mainly adopts fan forced ventilation or pumping liquid to heat or cool the battery pack. For example, the Chinese patent with the notification number CN201927684U discloses a liqui...
