Abstract
To stabilize the supply of power to the outside.SOLUTION: A power supply system 1 includes a charging line pair PL1 to which AC power is supplied from the outside, a power supply line pair PL2, a bidirectional charger 7 capable of switching between a charging mode in which the AC power supplied to the charging line pair PL1 is converted into DC power and supplied to a battery E, and a power supply mode in which the DC power supplied from the battery E is converted into AC power and supplied to the power supply line pair PL2, an AC inverter 9 connected to the battery E so as to be connected in parallel with the bidirectional charger 7, which converts the DC power supplied from the battery E into AC power and outputs it, and a power distribution unit 11 having a switch 37 switchable between a first switching state in which the AC power output from the AC inverter 9 is supplied to an outlet 15 in the charging mode, and a second switching state in which the AC power supplied from the power supply line pair PL2 is supplied to the outlet 15 in the power supply mode.SELECTED DRAWING: Figure 1
