場所に設置された専用の充電装置を使用していたため、
充電場所が限られる等、メンテナンスに制約があった。In conventional electric cars, a dedicated charging device installed at a predetermined location was used to charge the drive battery.
There were restrictions on maintenance, such as limited charging locations.

Conventionally, a contactor or switch is provided to disconnect either the ■ side or the e side of the drive battery from the running motor and the running chopper. In order to use the running chopper as a charging chopper, it is necessary to separate the driving battery and the running chopper at two contacts for insulation. One switch was added for this purpose, and a current detector was also required for charging control and running 11J control, so the current detector was placed on the drive battery side so that the charging current could be detected, and the control circuit was Two changeover switches are used to switch between charging control and driving control.

以下、本発明の一実施例を第１図により説明する。An embodiment of the present invention will be described below with reference to FIG.

て駆動バッテリー３の■側とｅ側に接続されている。In FIG. 1, the drive battery 3 is connected to the normally open contact of the main contactor 4 through the entire key switch 1, and the motor armature 5, running chopper 6, and current detector 7 are cut off from the common contact when the main contactor 4 opens and closes. It is configured to be connected to the e side of the drive battery 3 through the switch 2. A freewheel diode 8 is connected between the connection point between the motor armature 5 and the running chopper 6 and the main contactor 4. On the other hand, the DC-DC converter 10
The primary coil of the transformer is connected to the connection point between the cutoff switch 2 and the current detector 7, and the other end is connected to the connection point between the motor armature 5 and the running chopper circuit 6 via the rectifier circuit 12. Further, the secondary coil is connected to the ■ side and e side of the drive battery 3 through the rectifier circuit 11.

- A device for controlling the DC converter 10 will be formed. Therefore, the voltage obtained by rectifying the output of the AC power supply 9 in the rectifier circuit 12 is connected to the primary coil of the transformer through all the transistors of the running chopper 6, and constant current control is performed at the beginning of charging, and constant voltage at the end of charging. The control is performed by the control of the total control circuit 13, and the duty of the chopper 6 for traveling is controlled. By turning on and off the voltage of the primary coil in this manner, a stepped-down or stepped-up voltage is generated in the secondary coil, and the drive battery is charged via the rectifier circuit 11.

Also, by sharing transistors, high-speed switching is possible and the transformer can be made smaller. The charger can be made smaller by sharing transistors, sharing photodetectors, sharing part of the control circuit, etc. Therefore, there are effects such as being able to reduce the overall cost.
