Japanese Patent JP2019208301
Kind Code:
A
Abstract:
To prevent deterioration of charging efficiency when there is a change in dielectric constant due to ice and snow attached to a power receiving coil.SOLUTION: A power supply device has: a power reception unit that receives power from a power transmission unit in a non-contact manner in order to charge a battery mounted on a vehicle; a foreign matter detection unit that detects foreign matter between the power transmission unit and the power reception unit; and an ambient temperature sensor that measures the ambient temperature. When the foreign matter detection unit detects foreign matter, and the ambient temperature is equal to or lower than a prescribed value, power reception unit warming-up means warms up the power reception unit.SELECTED DRAWING: Figure 1
