Abstract

The invention provides a leakage detecting device and a leakage detecting system for a battery module. The battery module comprises a heat management assembly; the heat management assembly is provided with a first cavity which is used for accommodating a temperature control material; a gap is reserved between the leakage detecting device and the bottom of the heat management assembly. The leakage detecting device is provided with a leakage detecting assembly which is used for accommodating a conductive material; two ends of the leakage detecting device are connected with an external power supply; the external power supply and the conductive material in the leakage detecting assembly form an electric loop. When the heat management assembly leaks, the temperature control material enters the leakage detecting assembly accommodated with the conductive material along a side wall and the gap, and the electric loop formed by the external power supply and the conductive material in the leakage detecting assembly is disconnected so as to detect the leakage of the temperature control material in the heat management assembly. Therefore, the risk of existence of potential safety hazard is reduced; fateful and irreparable loss is avoided.

Description

technical field [0001] The invention relates to the technical field of battery thermal management, in particular to a leak detection device and a battery module leak detection system. Background technique [0002] The battery thermal management technology solves the problem of heat dissipation or thermal runaway caused by the battery working in an environment with too high or too low temperature, and improves the overall performance of the battery. [0003] However, if the cavity for thermal management of the battery is cracked or damaged, the temperature control material in the cavity will leak, posing a major safety hazard. Once a problem occurs, it will cause fatal and irreparable losses. Contents of the invention [0004] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a leak detection device and a battery module leak detection system, which are additionally equipped with a second cavity filled with conductive mate...
