Title: Battery charging device

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