Abstract

The invention discloses a detection method of an abnormal temperature-rise module. The detection method is applied to a power battery assembly, and comprises the steps that when it is detected that the power battery assembly is connected with a test system, communication connection between the test system and the power battery assembly is established; temperature-rise data of the power battery assembly under various temperature-rise conditions are obtained through communication connection; and the abnormal temperature-rise module in the power battery assembly is determined according to all thetemperature-rise data. According to the method, the abnormal temperature-rise module in the power battery assembly can be detected accurately, and the service life of the power battery assembly is prolonged. The invention further discloses a detection system of the abnormal temperature-rise module, a computer readable storage medium and electronic equipment, and the beneficial effects are achieved.

Description

technical field [0001] The present application relates to the technical field of new energy vehicles, in particular to a detection method and system for an abnormal temperature rise module, a computer-readable storage medium, and an electronic device. Background technique [0002] The power battery assembly is the core component of new energy vehicles, and its performance determines the intuitive experience of users during use. At present, the main two factors that mainly affect the promotion of new energy vehicles are charging time and driving range. The charging and discharging performance of power batteries under low temperature conditions is poor, resulting in long charging time and low actual charging capacity under low temperature conditions. If the charging current is increased blindly under low temperature conditions, there may even be safety hazards such as explosion and liquid leakage. Accidents happen. At present, most power battery assemblies use PTC heating to ...
