Leakage Location System of Electric Vehicle Battery Pack Based on Wavelet Transform

The proposed research study focuses on the leakage location system of the electric vehicle battery pack based on the Wavelet transform. Under the same equalization time, the equalization efficiency of the method that has been tested from the battery pack to the cell to the battery pack is 91.4%, and the overall equalization efficiency of this method is 93.8%. When the battery pack is in a discharging state, the equalization circuit module can complete the migration of the battery pack's power to the battery with the lowest terminal voltage or SOC. With the considerations of the mentioned features, this paper applies the wavelet model to construct the efficient location system. The proposed model is tested on the different scenarios with different data sets. The performance guides us that the accuracy of proposed model is much higher.
