The Study of Insulation Monitoring Method for Power Battery Pack

Abstract:

With the large-scale use of power battery pack, its security issues are attracting more attention, especially insulation faults. Traditional insulation monitoring methods can only detect insulation faults appeared at the most positive and negative ends of the battery pack, which cannot meet the requirements of monitoring the insulation state of an entire battery pack system. This paper analyzed the multi-point grounding insulation model of power battery pack, and obtained an equivalent model. A method of detecting the insulation resistance and locating the insulation fault was given, based on the equivalent model. The results of the simulation on Multisim 10.0 and the experiment test proved the correctness of the simplifying process of the insulation model and the insulation monitoring method.
