Abstract

The invention provides a leakage detection device and method, and relates to the technical field of battery liquid cooling detection. The device comprises an expansion kettle, a first liquid level detector, a second liquid level detector, and a processor. The first liquid level detector comprises a first float and a first liquid level detection assembly, and the second liquid level detector comprises a second float and a second liquid level detection assembly. The first liquid level detector and the second liquid level detector convert the liquid level heights of the corresponding positions ofthe first float and the second float along with the liquid level in the expansion kettle into electric signals and send to the processor. When the first liquid level height and the second liquid level height obtained by the processor according to the electrical signals are lower than the reference liquid level height value, it is determined that the battery liquid cooling system where the expansion kettle is located leaks. According to the leakage detection device and method, the accuracy of the leakage detection is improved, and the effective temperature management on an automobile power battery is facilitated.

Description

technical field [0001] The present application relates to the technical field of battery liquid cooling detection, in particular, to a leakage detection device and method. Background technique [0002] At present, automotive power batteries, as an emerging clean power energy, are gradually occupying the market with their advantages of low pollution, low energy consumption, and high conversion rate. Automotive power batteries will generate heat during use, and cooling devices or equipment are required to manage their temperature, such as liquid cooling equipment. Liquid cooling equipment may leak due to bumps, collisions, or aging, resulting in loss of coolant. The equipment cannot effectively manage the temperature of the vehicle's power battery, which may damage the vehicle's power battery or even spontaneously ignite, causing serious consequences. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present application is to provide ...
