Abstract

A charging and discharging system includes an electric storage device, a connection port configured to supply electric power between the electric storage device and the outside of a vehicle, a charger configured to receive electric power from the outside of the vehicle via the connection port and to supply the electric power to the electric storage device, a power converter configured to receive electric power from the electric storage device and to output the electric power from the connection port to the outside of the vehicle, a voltage detector configured to detect a voltage across output nodes of the power converter, and a control unit configured to control the power converter. The control unit causes the power converter to output electric power after checking that the voltage across the output nodes is in an inactive state when a command for outputting electric power from the power converter is received.

Dependent claims

A charging and discharging system comprising:

an electric storage device;
a connection port configured to supply electric power between the electric storage device and the outside of a vehicle;
a charger configured to receive electric power from the outside of the vehicle via the connection port, the charger being configured to supply the electric power to the electric storage device;
a power converter configured to receive electric power from the electric storage device, the power converter being configured to output the electric power from the connection port to the outside of the vehicle;
a voltage detector configured to detect a voltage of an output node of the power converter;
and
an electronic control unit configured to control the power converter such that the power converter outputs electric power after the electronic control unit checks that the voltage of the output node is in an inactive state when the electronic control unit receives a command for outputting electric power from the power converter.
