Abstract

With the increasing deployment of energy storage devices in electric
vehicles and distributed renewable power network, the extensive research on battery charging systems has shown a growing significance. This paper focuses on developing a new charging method which aims at extending the lifespan of lithium-ion battery by using bipolar current pulses. A battery charging system employing a phase-shift controlled dual active bridge and battery elements has been studied and its small-signal average model is established to investigate the dynamic control of the proposed bipolar pulse charging approach. Furthermore, the influence of the negative pulse on eliminating the polarization effect and inhibiting the ageing of the lithium-ion battery has been analyzed in detail. Finally, an advanced four-stage battery charging strategy is proposed to achieve the suppression of the ageing effect and potentially extend the battery life, which also shows a 7.58% reduction of the total charging time compared with the traditional charging method.
