<P>PROBLEM TO BE SOLVED: To enable securing the braking force by storing the braking power in the power storage device and reuse of the stored power without providing an adjustment means of the power and without influencing the operation of room lights and the air conditioning apparatus in the process of storing and reuse in an electric vehicle with the power storage device. <P>SOLUTION: The electric vehicle is operated at power running time by shutting switches 5 and 7, connecting an auxiliary power supply device 3 and an electric vehicle drive device 4 to a current collecting device 1, and supplying power from a trolley wire to an auxiliary power supply device 3 and the electric vehicle drive device 4. The generated power of the electric vehicle drive device 4 is stored in the power storage device 2 and the electric brake power is secured, without influencing the auxiliary power supply device and the trolley wire by opening a switch 7, shutting switches 5 and 6, and connecting a current collecting device 1 and an auxiliary power supply device 3, and a power storage device 2 and the electric vehicle drive device 4 at braking time. When reusing the electric power stored in the power storage device 2, the switch 7 is opened, the switches 5 and 6 are shut and the power is supplied to the electric vehicle drive device 4 without influencing the auxiliary power supply device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
