Title:
VEHICLE CHARGE SWITCHING DEVICE AND VEHICLE CHARGING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/170798
Kind Code:
A1
Abstract:
The present invention proposes, in a vehicle charging system equipped with a plurality of charging connectors, a techique capable of preventing conduction between the charging connectors and efficiently performing charging control on a vehicle battery. This charge switching device (1) has: an input-side conductive path group (50) for transmitting the powers from respective output units (12) through first conductive paths (50A to 50F); an output-side conductive path group (51) in which second conductive paths (51A to 51C) form power paths to respective charging connectors (30A to 30C); an intermediate conductive path group (52) in which, at a plurality of branch portions (52A) which correspond to the first conductive paths (50A to 50F) and in which a plurality of third conductive paths (52B) branch, each of the third conductive paths (52B) branches from the first conductive paths (50A to 50F) to the respective second conductive paths (51A to 51C); and a switch group (55) in which a plurality of switches (53) correspond to the respective third conductive paths (52B) and the respective switches (53) switch the corresponding third conductive paths (52B) between an energization permission state and an energization interruption state.
