Power management in electric Vehicle has been revolutionized since the old power structure introduced with first EVs. Today, it can be powered either by a single or a combination of multiple sources and driven by a single or a combination of multiple algorithms. This enhancement contributes in significantly better results. This paper reviews state-of-art on electric vehicle concept giving description for each sub-category, and then details power management strategies and charging techniques highlighting main problems and solutions. Finally, power management structure and future research direction are also discusse
