Lithium‐ion battery equipped with AC feature for using in electric/hybrid vehicles

In this study, a lithium (Li)‐ion battery equipped with an AC feature suitable for using in electric/hybrid vehicles is presented. The AC feature is implemented based on a proposed single‐phase symmetric pulse‐width modulation technique. Using the proposed Li‐ion battery including both DC and AC features (DC–AC power source) in electric/hybrid vehicles has some advantages such as less electric power consumption compared with a normal Li‐ion battery, no generated harmonics and the capability of choosing the AC voltage frequency. Simulated results obtained by performing in Proteus 6 environment validate the theoretical results presented in this study. An experimental prototype of the proposed DC–AC power source has been built. The experimental results not only verify the simulation and theoretical results but also show that 20% reduction in the electric power consumed by electric/hybrid vehicles is achieved using the proposed DC–AC power source.
