Abstract
Electric Vehicle is widely used in passenger service gradually. It is a critical successful factor to have a sufficient electric energy supply. In order to solve the constraint of economical issue, the fast charging method can decrease the charging time such that the service time can be extended without dramatically increasing the battery numbers. This research develops a fast charging system which follows international regulation. The fast charging system includes a charging station simulation system, a battery loading simulation system, and a charging controller mounted on a fast charging vehicle. This system has completed connection tests with charging stations of ABB from Europe and Delta in Taiwan and also finished system verification with Japan HASETEC, which is a major company involving in CHAdeMO association affair. The developing charging controller undergoes several charging/discharging experiments for marine high capacity lithium ion battery module. The cells of the battery module still maintain reasonable balance status after charging process, which proves the developed charging controller of this research can safely and efficiently fast charge a lithium battery module via high voltage direct current. It is the goal for this research that promote adopting electric boat in touring water field for carbon emission reduction and water resource protection can be realized all at once.
