PURPOSE:To continue running even when the residual amount of charge of a capacitor vanishes before arrival at the next charging station, due to traffic jam and the like, in regard to an electric vehicle which is made runnable at a long distance by charging the capacitor, a power source for running, at charging stations as occasion demands. CONSTITUTION:An electric double-layer capacitor 1 feeds a motor-generator 13 for running with electricity, while it is charged, as occasion calls, at a charging station provided at every specified interval on a running route. The motor- generator 13 is designed, on the other hand, to be fed also by a lead accumulator 2 charged beforehand. The running is made normally by feeding from the electric double-layer capacitor 1, and when the residual amount of charge of the electric double-layer capacitor 1 lessens to a prescribed value or below, the running is continued by feeding from the lead accumulator 2. |
