Summary:Abstract Inconsistencies are inevitable in the practical application of battery packs of new energy vehicles, which will reduce the energy utilisation rate and service life and even endanger the safety of the battery system. To reduce the inconsistency of battery packs, this study innovatively proposes an integrated active balancing method for series‐parallel battery packs based on LC energy storage. Only one inductor and one capacitor are used to store energy to achieve the balance of each cell in a series‐parallel battery pack. This design has the characteristics of simple structure, small volume, fast balancing speed and easy expansion. By building an experimental platform, the effectiveness of this novel integrated balancing method is verified.
