摘要：A charging controller (25) acquires the power loss of a power transmission coil(31) from a power supply device (100) via wireless communication. A temperature
estimation unit (33) estimates the ambient temperature of a power reception coil on thebasis of a preset amount of heat generation of a power reception device (200) and thepower loss of the power transmission coil (31). In this case, when the positional
relationship between the power transmission coil (31) and the power reception coil (41) isshifted from a normal positional relationship, the temperature estimation unit (33)increases, in accordance with the magnitude of positional shift amount, the contributionto a temperature rise due to the power loss of the power transmission coil (31).Accordingly, an abnormal increase in the ambient temperature of the power receptioncoil (41) can be prevented.
