<p><P>PROBLEM TO BE SOLVED: To provide an auxiliary power source charging/discharging structure for avoiding damage to a harness resulting from an overcurrent and shortening a charging time for an auxiliary power source while suppressing a cost increase. <P>SOLUTION: The auxiliary power source charging/discharging structure comprises the auxiliary power source 5 charged by supplying power from a main power source 3 for supplying power to electronic equipment 4 mounted to a vehicle, a restricting circuit 19 for restricting the power supply from the main power source 3 to the auxiliary power source 5, a change-over means 22 for changing over the state of supplying power from the main power source 3 to the auxiliary power source 5 between the first state of power supply via the restricting circuit 19 and the second state of power supply bypassing the restricting circuit 19, and a control means 1 for controlling the operation of the change-over means 22 in accordance with the charged amount of the auxiliary power source 5. The control means 1 is constituted so that the change-over means 22 selects the first state of power supply when the charged amount of the auxiliary power source 5 does not reach a prescribed voltage, and selects the second state of power supply when the charged amount of the auxiliary power source 5 reaches the prescribed voltage. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
