Abstract

The invention provides a battery cooling liquid linkage detection device, a battery cooling system and an automobile. The battery cooling liquid linkage detection device comprises at least one hydrogen concentration detection unit, a processing unit and an alarm output unit, wherein the hydrogen concentration detection units are arranged inside a battery accommodation space for holding battery modules on the automobile and are electrically connected with the treatment unit; the hydrogen concentration detection units are used for detecting the concentration of hydrogen generated when a coolingliquid leaking from the battery accommodation space and are used for transmitting the detected hydrogen concentration to the processing unit; the processing unit is connected with the alarm output unit; when the hydrogen concentration detected by using the hydrogen concentration detection units meets a first preset concentration threshold, a leaked liquid alarm signal can be output from the alarmoutput unit. Therefore, the leakage situation of a battery module cooling liquid can be effectively monitored, and danger caused by the hydrogen concentration can be avoided.

Description

technical field [0001] The present application relates to the technical field of electric vehicle batteries, in particular, to a battery coolant leak detection device, a battery cooling system and a vehicle. Background technique [0002] Due to rising energy costs and increasingly serious environmental pollution problems, 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. As the main energy storage component of electric vehicles, battery modules are key components of electric vehicles and directly affect the performance of electric vehicles. The battery module will generate a lot of heat when it is working, so it is necessary to cool down the battery module in time. In the prior art, a liquid cooling device is often used to cool down the battery mode, and the liquid cooling device injects cooling liquid into a liqu...
