1. A power supply apparatus for supplying electric power from a vehicle body to a slide door slidable mounted on the vehicle body of a vehicle, the power supply apparatus comprising: a primary coil provided to the vehicle body; a secondary coil provided to the slide door, wherein the primary and secondary coils can be brought into proximity to each other upon closing of the slide door to effect a mutual induction operation so as to supply the electric power; a temperature sensor provided in a vicinity of the primary coil; a primary coil control device which is connected to the temperature sensor, and stops excitation of the primary coil in accordance with the temperature of the primary coil or the vicinity of the primary coil detected by the temperature sensor, so as to interrupt a supply of the electric power to the slide door; a slide door-contained battery for supplying electric power to a load driver driving and controlling at least one load on the slide door at least when the slide door is opened or when the supply of the electric power to the slide door is interrupted; and charging means for charging the slide door-contained battery with the electric power supplied to the slide door through the secondary coil. 2. The power supply apparatus according to claim 1 further comprising an alarm unit for warning of abnormality of the power supply judged by the primary coil control device in accordance with the temperature detected by the temperature sensor. 3. A method of supplying electric power from a vehicle body to a slide door slidably mounted on the vehicle body of a vehicle, in which the electric power is supplied to the slide door by a mutual induction operation of a primary coil provided to the vehicle body and a secondary coil provided to the slide door when the slide door is closed, the method comprising the steps of: comparing temperature of the primary coil or temperature of a vicinity of the primary coil detected by a temperature sensor with a threshold value, and stopping excitation of the primary coil when the detected temperature exceeds the threshold value, so that the supply of the electric power to the slide door is interrupted. 4. The method according to claim 3, further comprising the step of warning abnormality of a power supply through an alarm unit when the temperature detected by the temperature sensor exceeds the threshold value.
