Abstract

Embodiments in the invention provide a leak detection apparatus and a battery module. The leak detection apparatus is applied to the battery module. The battery module comprises a battery cell unit and a fixing assembly used for fixing the battery cell unit. The leak detection apparatus comprises a pressure transducer, a processing controller and an alarming unit, wherein the pressure transducer is arranged between the fixing assembly and the battery cell unit; the processing controller receives and processes an electric signal transmitted by the pressure transducer so as to obtain pressure between the fixing assembly and the battery cell unit; and when the pressure exceeds a preset pressure range, the processing controller controls the alarming unit to sound an alarm. Thus, the leak detection apparatus detects whether the fixing assembly has a liquid leak and realizes alarming when the fixing assembly has the liquid leak.

Description

technical field [0001] The invention relates to the technical field of battery heat management, in particular to a leak detection device and a battery module. Background technique [0002] At present, environmental pollution is very serious, and one of the main causes of environmental pollution is the exhaust emission of automobiles. Because pure electric vehicles have less or no exhaust emissions, the research and development and design of pure electric vehicles are increasingly favored by major manufacturers, and the energy of pure electric vehicles mainly comes from battery modules. [0003] As the main energy storage component of electric vehicles, battery modules are key components of pure electric vehicles and directly affect the performance of pure electric vehicles. The current battery modules are generally lithium-ion power batteries. Although lithium-ion power batteries have excellent power output characteristics and long life, the performance of lithium-ion power...
