Vehicle charging device and vehicle charging system using same

摘要

Disclosed is a vehicle charging device that can perform communication even if the vehicle charging device and a charging instruction device are connected to power line pairs having different phases in a multiple-wire power line. The vehicle charging device includes: a power line communication unit that performs communication over a multiple-wire power line or a power line for vehicles; a power line connection unit that connects a pair of power lines within the multiple-wire power line to the power line for vehicles; and a control unit that controls the connection or the disconnection of the power line connection unit. The power line communication unit selects a signal from a pair of power lines within the multiple-wire power line and communicates with the charging instruction device, and performs communication with the vehicle over the power line for vehicles.
