Abstract
Quick Charger does note only charge Electric Vehicle (EV) rapidly but also mitigate the range anxiety of drivers of EV. The drivers who have experienced the driving of EV often refer to the range of anxiety to use up batteries on EV. Range anxiety tends to be overemphasized than what actually is, considering the usage pattern of EV. There is a report to show that the usage of EV has been promoted after the installation of Quick Chargers. Therefore, the build-up of charging infrastructure utilizing Quick Charger is indispensible for the penetration of EV into market. In this paper, discussed is the system configuration and function of present Quick Charger and prospect of future development of Quick Charger. To encourage the wide use of Quick Charger, Quick Charger is featured by versatility, user-friendliness and safety in the event of charging EV. In order to materialize versatility, Quick Charger complies with CHAdeMO protocol, which ensures the charging of various types of EV, as long as EV complies with CHAdeMO. With regards to the safety and reliability, several measures such as insulation checking, protection and supervision by self-checking are adopted to achieve the high level of safety for general public using Quick Charger. Following the guidance on the LCD display, the entire operation of charging can be completed safely and easily by pushing START button after the connection of the cable.
