Abstract: The adaption of electric vehicle in worldwide is increasing in acceleration fashion while in Malaysia has been a slow hike, especially with the lack of infrastructure development. There are few conventional charging stations of EV are set up in shopping malls and hotels are not enough to initiate the EVs in the country. However, the charging awaiting time is quite longer could be about 5 to 6 hours which makes Malaysia is slowly falling out from EV trend. The development of quick charging system from this study might be considered as the development of electric mobility solutions. A prototype on-board charging system with three different charging modes: the slow charging mode is normally considered for residence, medium charging mode for office parking lots, and fast charging mode for charging station on road. The quick charging mode has been developed to charge the battery in 1.5 – 2.0 hours with maximum charging current 50 A with auto activated quick evaporative battery thermal management system. The performance of the quick charging system has shown that the battery to be charge up to 85% of its rated capacity by constant current mode rather than constant voltage, which has shorten the battery charging time by 16%. However, it might shorten the battery life about 5% due to the fast redox reaction of the electrochemistry of battery.
