Abstract

Lithium ion battery was applied to the running of variable voltage variable frequency (VVVF) inverter-type railcar. A 15 kWh of Mn-type lithium ion battery was used. The relation between running time and voltage, current and integrating watt was investigated. The running test was also carried out using VVVF inverter-type railcar to investigate charge performance due to regenerative energy. Lithium ion battery module was quickly charged for three times at rate of 4.68 C by regenerative braking system. It was estimated that the effect of energy saving was about 22% by the charge of lithium ion battery from regenerative energy. Copyright © 2009 Institute of Electrical Engineers of Japan.
