Abstract

Loads (53) in a slide door are in a stopped condition, and the charging rate of a slide door-contained battery (38) is below a predetermined value, the slide door-contained battery (38) is charged. When the charging rate of the slide door-contained battery (38) is above the predetermined value, the trickle charging is effected.

Claims

1. A method of charging a slide door-contained battery, mounted in a slide door slidable mounted to a vehicle body of a vehicle, with electric power supplied from the vehicle body to the slide door, the method comprising the step of:

substantially continuously charging the slide door-contained battery with the electric power only when a load in said slide door is in a stopped condition and a charging rate of the slide door-contained battery is below a predetermined value.

2. The method according to claim 1 further comprising the step of trickle charging the slide door-contained battery when the charging rate of the slide door-contained battery is above the predetermined value.

3. The method according to claim 1, wherein the electric power is supplied from the vehicle body 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.

4. A method of charging a slide door-contained battery, mounted in a slide door slidable mounted to a vehicle body of a vehicle, with electric power supplied from the vehicle body to the slide door, the method comprising the step of:

charging the slide door-contained battery with the electric power when a load in said slide door is in a stopped condition and a charging rate of the slide door-contained battery is below a predetermined value; and

trickle charging the slide door-contained battery when the charging rate of the slide door-contained battery is above the predetermined value.

5. A method of charging a slide door-contained battery, mounted in a slide door slidable mounted to a vehicle body of a vehicle, with electric power supplied from the vehicle body to the slide door, the method comprising the step of:

charging the slide door-contained battery with the electric power when a load in said slide door is in a stopped condition and a charging rate of the slide door-contained battery is below a predetermined value, wherein the electric power is supplied from the vehicle body 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.
