| Abstract |
Electric Vehicles (EV's) are needed in densely populated urban areas to reduce air pollution. Battery chargers are needed to supply dc voltage to charge the high energy battery packs used in EVs. This paper deals with an on-board battery charger arrangement which is fully based on the use of the power components of the EV motor drive. Desired features for EV battery chargers such as minimum volume, low cost, high efficiency and high reliability are fully matched by means of the proposed solution. No additional power components to the motor drive arrangement are required. EV motor drive power devices turn out to be oversized with respect to technical specifications of the charger design resulting in high efficiency of the battery charge system. Moreover, during both monitoring and charging mode of operation of the motor drive arrangement, a small size dc-dc power electronic converter provides the maintenance charge of an auxiliary battery from the propulsion battery. The proposed on-board charger arrangement has been installed on an electric scooter prototype being developed for the Far East markets. Design analysis and experimental results of the on-board charger prototype are presented. |
