PROBLEM TO BE SOLVED: To provide a quick charger and a quick charging system that are able to quickly charge a capacitor at its acceptable maximum output capacity even if the rated output capacity of a single quick charger is less than the acceptable maximum output capacity of the capacitor.SOLUTION: A quick charger 3 comprises: a DC power supply unit 17; a power supply control unit 19; a command generation unit 21; a communication unit 23; a supply output capacity determination unit 25; a power supply switching circuit 27; an external power reception unit 31 for receiving DC power from another quick charger; an additional power addition circuit 33 that, when the supply output capacity determination unit determines that DC power alone is less than the maximum output capacity, receives additional DC power, adds the additional DC power to the DC power output by the power supply switching circuit, and thereby secures output capacity to be supplied; and an external power feeding unit 29 for outputting DC power to another quick charger. A quick charging system is constructed by electrically connecting the quick charger and a quick charger with the same configuration.SELECTED DRAWING: Figure 2 |
