One of the main electrical and mechanical units for electric vehicles (EV) and plug-in hybrid vehicles (PHEV) is battery charger to control the energy balance of entire system. In recent, off-board charger for fast charging and on-board charger for slow charging have been developed. The power rating f battery charger is about more than 50kW for offboard charger and 3.3kW for on-board charger. Therefore, if the primary power of the charger is provided though the utility grid, the entire power rating of existing grid should be increased and several safety and reliability problem should be considered [1]-[2]. With this reason, for EV and PHEV applications renewable energy sources are considered as the alternative solution of limitation of utility grid power capability.
