Abstract

The invention provides a leakage detection device and a cell management system. The leakage detection device is applied to a cell module, and comprises a temperature control assembly and a leakage detection piece used for detecting leakage conditions of the temperature control assembly. The leakage detection piece is fixedly connected with the temperature control assembly and is arranged in an easily leaking place of the temperature control assembly. When a leakage occurs in the temperature control assembly, the leakage detection piece is damaged and breaks along with the easily leaking place. By detecting the breaking states of the leakage detection piece, detection of leakage conditions of the temperature control assembly is achieved. Thus, the leakage conditions of the temperature control assembly can be timely detected, hidden safety hazards are reduced and serious 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 management system. Background technique [0002] At present, due to the increasingly prominent problems of energy costs and environmental pollution, new energy vehicles (pure electric vehicles and hybrid electric vehicles) have been raised to the height of national strategies due to their energy-saving, environmental protection, and economical characteristics. However, pure electric and hybrid vehicles still have many technical problems to be solved. The heat-related problems of the battery are the key factors that determine its performance, safety, life and cost. The temperature level of a battery directly affects its energy and power performance in use. 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 l...
