A Novel Battery Matching Algorithm Based On Discharge Curve

Aiming at the problems of low battery matching rate and poor battery performance after matching, a battery discharge curve-based matching method is proposed. Specifically, we use the complete battery discharge curve to fit the batteries so that the most similar curves can be divided into a group. Due to the excessive battery curve data, the calculation burden is large. This problem can be addressed by data dimensionality reduction. In this article, the method of principal component analysis is used to reduce data dimensionality. The variance of the battery discharge curve in the battery pack is used to measure the performance of the battery pack. The experimental results prove that the proposed method has improved both the composition power and battery pack performance compared with the existing battery matching schemes.
