Document Type and Number:
Japanese Patent JP6825395
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately estimate a time necessary for non-contact external charging.SOLUTION: A vehicle charging system includes a vehicle and power supply equipment outside the vehicle. The vehicle includes: a power storage device; a power reception coil capable of receiving power for charging the power storage device without contact from a power transmission coil of the power supply equipment; a communication device configured to be able to communicate with the power supply equipment; and an ECU for controlling execution of non-contact external charging to charge the power storage device with power received by the power reception coil without contact from the power transmission coil of the power supply equipment. If executable conditions of non-contact external charging are established, the ECU transmits a preparatory power transmission request to the power supply equipment, measures power actually received by the power reception coil from the power transmission coil of the power supply equipment after the transmission of the preparatory power transmission request, and calculates a time necessary for non-contact external charging by using the measured power.SELECTED DRAWING: Figure 3
