POWER FEEDING SYSTEM AND CONNECTION CONNECTOR

WIPO Patent Application WO/2013/035852

A1

Provided is a power feeding system by which, when a power feeding device and a vehicle on which an electric storage device to which power is fed from the power feeding device is mounted, are connected using a power feeding line used for power feeding, a grounding line, and a control line used to transmit control signals used for controlling power feeding to the electric storage device, occurrence of crosstalk between the power feeding line and the control line and between the power feeding line and the grounding line, within a charging cable enveloping the power feeding line, the control line, and the grounding line, can be suppressed. Also provided is a connecting connector. A winding number ratio between a primary coil (40a (22a)) connected to at least one of the control line (32) and the grounding line (33), and a secondary coil (40b (22b)) connected to a communication unit which transmits/receives communication signals, is set to 1:N (N > 1) in a system wherein VnC > VnL, and is set to N:1 (N > 1) in a system wherein VnC < VnL.
