POWER SUPPLY SYSTEM

摘要

A power supply system comprises: PV DC/DC converter which converts power supplied from the solar panel; EV DC/DC converter which can convert power supplied from the house side bus and supply the power to an electric vehicle; an in-house relay; a fast charging and discharging relay; a joint part; and a controller which turns the in-house relay off and at the same time turns the fast charging and discharging relay on to cause an aggregated power of the power converted by the EV DC/DC converter and the power supplied to the joint part via a fast charging and discharging route to be outputted to the electric vehicle via the electric vehicle wiring.

1. A power supply system comprising:
a first power converting part which is connected to a solar cell to convert power supplied from the solar cell and to output the power to an in-house power wiring provided inside a house; a second power converting part which can convert power supplied from the in-house power wiring via a first route and supply the power to an electric vehicle through an electric vehicle wiring; a first relay provided between the in-house power wiring and the first power converting part; a second relay provided between the first power converting part and the second power converting part; a joint part provided to the second power converting part and connected via the second relay and a second route; and a controller which turns the first relay off and at the same time turns the second relay on to cause an aggregated power of the power converted by the second power converting part and the power supplied to the joint part via the second route to be outputted to the electric vehicle via the electric vehicle wiring.
