Problems solved by technology

After a battery cell placed in the traditional battery box explodes, high-temperature and high-pressure gas is sprayed from the pressure relief valve at the open end and accumulates in the battery box, which is likely to cause a series of explosions in other battery cells.

Abstract

The invention relates to a battery case, a battery cell installation assembly and a battery pack. The battery case comprises: a case body, wherein the case body is provided with an inlet / outlet, at least two through holes are formed in the side wall of the case body at intervals, and the through holes are opposite to nozzles of a pressure release valve of a battery cell installed in the case body; and a waterproof layer, wherein the melting point of the waterproof layer is lower than a pre-set temperature, and the waterproof layer seals the through holes. According to the battery case, the battery cell installation assembly and the battery pack, the problem of serial explosion of other battery cells caused by explosion of a certain battery cell placed in the case can be avoided, and explosion of the whole battery pack is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a battery box, a battery cell installation assembly and a battery pack. Background technique [0002] The battery pack of an electric vehicle generally consists of multiple batteries connected in series + parallel to form the required voltage and capacitance. The multiple batteries are fixed with brackets and placed in a closed battery box to prevent collisions, shocks and waterproofing. . [0003] The battery cell consists of a metal punched cylindrical shell with one end closed and one end open. The shell contains a dielectric medium. The closed end of the battery cell is connected to the negative electrode of the dielectric storage medium. The open end of the battery cell is provided with a pressure relief valve and a positive terminal. When the storage medium in the cell is short-circuited, the high-pressure and high-temperature gas generated can be ejected fr...
