Problems solved by technology

The power battery device will generate a lot of heat during charging and discharging, especially under high rate and harsh working conditions. If the heat is not dissipated in time, the heat inside the battery will rise sharply, seriously affecting the performance of the power battery. Shorten battery life and even lead to thermal runaway and safety accidents

Abstract

The present application provides a power battery device, which includes a phase-change material housing, several battery packs and a box; the phase-change material housing is arranged in the box; the phase-change material housing includes a peripheral plate and A plurality of partition plates, a plurality of the partition plates are evenly arranged inside the peripheral plate, so that the inside of the phase change material casing is in a grid shape; a plurality of the battery packs are arranged in the phase change material casing Each battery cell of each battery pack is separated by the partition plate, so that multiple sides of the battery cells are in contact with the phase-change material casing. The application solves the technical problem of how to design a power battery device with good cooling effect and simple structure.

Description

technical field [0001] The present application relates to the technical field of battery heat dissipation, and in particular to a power battery device. Background technique [0002] As a new type of modern transportation, electric vehicles have gradually become the most commonly used means of transportation for people to travel. Electric vehicles are powered by batteries and do not consume traditional fossil energy. They are incomparable to traditional vehicles in terms of energy saving, emission reduction and environmental protection. The advantages. [0003] The power battery of an existing electric vehicle is generally composed of a square lithium battery or a cylindrical lithium battery through series or parallel connection to form a high-power, large-capacity lithium battery pack. The power battery device will generate a lot of heat during charging and discharging, especially under high rate and harsh working conditions. If the heat is not dissipated in time, the heat ...
