Abstract
There are several ways to improve the mileage of the electric vehicle (EV). High-efficiency drivetrain and high energy density are the main factors. Energy storage source for EV obtained from the battery, ultra-capacitor (UC) and fuel cells (FC). Each of that has own characteristics and capacity. The battery has a good energy density, UC and FC are superiors on power density. Combining some of the energy storage will improve performance and mileage. On this paper, the topology of combining energy storage are reviewed. In addition, also review the power management strategy of hybrid energy storage. By using a convenient strategy, hybrid energy storage becomes very worth.
