One of the main challenges in the modern commercialized electric vehicle (EV) is the battery management system. In this paper a novel strategy of EV power management is presented based on direct torque space vector modulation. We used the battery state of charge (SOC) which is the percent of residual capacity by nominal capacity. The proper estimation of SOC of Lithium-ion battery provides an energy management system in EV. The proposed controller provides a good torque control and speed stability improvement.
