[0024] The following will refer to Figures 1 to 9B A first embodiment of the present invention is described. figure 1 is a schematic diagram showing the entire configuration of the charging and discharging system 100 for a vehicle according to the first embodiment of the present invention. Such as figure 1 As shown, the charging and discharging system 100 includes a vehicle 3 and a charging and discharging device (charging / discharging device) 7 . An example of vehicle 3 is an electric vehicle (EV). The electric vehicle 3 includes a battery 1, an inverter 2, and a control unit 3c. The battery 1 stores direct current, and the inverter 2 converts the direct current stored in the battery 1 into alternating current within the electric vehicle 3 . Thus, the electric vehicle 3 also functions as a generator. The electric vehicle 3 also includes an inlet 4 . The electric vehicle 3 is connectable to a charging and discharging device 7 via a charging and discharging cable 6 . The...

Abstract

A charge and discharge system for a vehicle includes an electric vehicle having a battery and an inverter, a charge and discharge device having a first relay and a second relay, and a commercial power source. An interlock mechanism is applied to the first relay and the second relay, and the interlock mechanism prevents one of the first relay or the second relay being closed when a remaining one of the first relay or the second relay is in a closed state. The first relay includes two first electric contacts that are normally open and are connected between a branch point and the commercial power source, and the second relay includes two second electric contacts that are normally closed and are connected to the branch point.

Description

technical field [0001] The present invention relates to a charging and discharging system for a vehicle that converts direct current (DC) power stored in a vehicle battery into alternating current (AC) The converted AC power is supplied to an external device. Background technique [0002] As disclosed in JP2012-070577 (corresponding to US2013 / 0082663A1), a discharge system discharges direct current stored in a battery of an electric vehicle to an external device. The discharge system disclosed in JP2( )12-070577A is for improving discharge safety. [0003] The discharge system described above includes an electric vehicle configured with a battery unit and a discharge device that discharges electric power stored in the battery unit of the electric vehicle. In an electric vehicle, two switches are arranged in the corresponding power line and two switching elements are also arranged in the corresponding power line. Each power line connects a connector to which a discharge de...
