<P>PROBLEM TO BE SOLVED: To further extend the lives of batteries, in a power transmission/reception device mounted to a vehicle. <P>SOLUTION: A drive system 2 drives a vehicle. The batteries 3, 4 are chargeable and dischargeable batteries. A non-contact power transmission/reception part 5 transmits and receives power to/from the outside in a non-contact manner. An inverter 6 with a switch function is switchable in connecting the batteries 3, 4 to the drive system 2 and discharging electricity, or in connecting the batteries 3, 4 to the non-contact power transmission/reception part 5 and charging electricity at each battery. Detection parts 3A, 4A detect residual amounts of the batteries 3, 4. During the travel of a vehicle body 1, a control part 8 connects the battery whose detected residual amount is reduced below a prescribed threshold to the non-contact power transmission/reception part 5 and charges the battery, and controls the inverter 6 so as to discharge electricity by connecting the other battery to the drive system 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
