Abstract
A battery charging device includes a power supply coupler and a power receiver coupler. The power supply coupler includes a primary coil, a communication unit to communicate the power receiver coupler, a thermistor for detecting the temperature of the power supply coupler, and a communication interruption circuit for interrupting a communication signal when the predetermined value is detected by the thermistor. When the temperature of the power supply coupler exceeds the predetermined value, a signal is produced by the communication interruption circuit to prevent an excessive temperature rise in the power supply coupler. The signal may, for example, stop the supply of electric power to the power supply couple.
