Leakage inspection device and battery module

Abstract

The invention relates to the technical field of leakage inspection equipment and a battery, in particular to a leakage inspection device and a battery module. The leakage inspection device is applied to a liquid cooling device of the battery module; the liquid cooling device comprises a component to be tested for containing cooling liquid; the leakage detection device comprises a liquid detection element, a central controller and a warning device; the central controller is electrically connected with the liquid detection element and the warning device; when detecting the liquid leakage of the component to be detected, the liquid detection element sends triggering information to the central controller; the central controller is used for controlling the warning device to warn when receiving the triggering information. The leakage inspection device and the battery module can feed back the cooling liquid leakage condition to a user in time, so that the user can take corresponding leakage blockage measures in time; the problems of battery rustiness, battery short circuit, battery damage, battery explosion, roadside breakdown and the like due to cooling liquid leakage can be solved; the service life of the battery is prolonged; the personnel safety of the user is protected.

Description

technical field [0001] The invention relates to the field of leak detection equipment and battery technology, in particular to a leak detection device and a battery module. Background technique [0002] In recent years, due to the increasingly prominent problems of energy costs and environmental pollution, pure electric vehicles and hybrid vehicles have attracted the attention of the government and various automobile companies because of their advantages of greatly eliminating or even zero-emission vehicle exhaust. The power battery is the core of pure electric vehicles and hybrid vehicles, and the heat dissipation of power batteries is a key issue restricting the development of pure electric vehicles and hybrid vehicles. [0003] The large size of the power battery module makes the ratio of its surface area to volume relatively small, and the internal heat of the battery is not easy to dissipate, resulting in accelerated battery attenuation and shortened battery life.
