Abstract
The safety management of traction battery is important means to ensure the safe operation of new energy vehicles, which directly affects the durability and reliability of vehicle. In this paper, three aspects, i.e. the safety concept, key technologies and futural development trend of traction battery are reviewed, in which the key technologies of battery safety including the mechanism and control measures of thermal runaway and protective structures are expounded respectively, with their achievements and inadequacies comparatively analyzed. Finally aiming at the challenges the current safety management of traction battery faces, the development trend of battery safety management in the future is given - from mechanism analysis to system design optimization and from passive safety protection to active safety prediction.
