- Focusing on the problem of serial cell imbalance in lithium-ion batteries applied in electric vehicles (EVs), this paper presents an active battery balancing method based on state-of-charge (SOC). The basic principle of the proposed balancing method is aligning battery cell SOCs to 50% and making sure all the cells are charged and discharges equally, so that good performance in improving capacity and anti-aging can be achieved. In this method, bidirectional Buck/Boost converters are implemented as the balancing nodes (BNs), and constitute a decentralized structure. Each individual BN and its control is independent, which makes the design modular, simple and flexible. The experimental results show the good performance of the proposed method in improving battery capacity and extending cycle life.
