Abstract:

 To enhance the energy conversion efficiency of energy storage system, a hybrid sinusoidal-pulse current (HSPC) charging strategy based on Li-ion battery was proposed. Firstly, this paper discussed the principle of using wide frequency band current to enhance the energy conversion efficiency of Li-ion battery, based on the AC impedance spectrum characteristics of Li-ion battery. Then, the method that paralleled boost converter and phase shifting technology were applied to generate hybrid sinusoidal-pulse charging current was compared with constant current charging method and pulse current charging method. Finally, the simulation and experimental results show the effectiveness of the proposed method.

Key words: Li-ion battery, AC impedance, energy storage, charging method
