Abstract

In an electrically driven vehicle equipped with a battery usable for running, a power generation unit of engine driven type that charges the battery is detachably mounted on the vehicle including a case where at least an engine of the power generation unit is detachably mounted, and the vehicle includes first stop means for bringing the power generation unit in a stopped state when the power generation unit is installed in or removed from the vehicle, and a generation stop switch for making an operation request to the power generation unit. More specifically, the first stop means stops an operation request signal to the power generation unit through low-voltage system wires when the generation stop switch is ON (no operation request is made).

Claims

1. An electrically driven vehicle equipped with a battery usable for running, comprising:

a power generation unit of engine driven type that includes a generator charging the battery and an engine driving the generator, at least the engine out of the generator and the engine being installed in and removed from the electrically driven vehicle;

a source for running supplied with power from the battery;

hold means holding the power generation unit in a state in the power generation unit is installed in the electrically driven vehicle;

stop means for bringing the power generation unit in a stopped state when the hold means stops holding the power generation unit in the state in which the power generation unit is installed in the electrically driven vehicle;

electromagnetic function generation means that is mounted on the vehicle and generates an electromagnetic function in a case where no operation request to the source for running is made; and

means that is installed in the power generation unit and is removable from the vehicle along with the power generation unit, the means bringing the power generation unit into a stopped state when receiving the electromagnetic function by the electromagnetic function generation unit.

2. The electrically driven vehicle according to claim 1, further comprising:

a lock mechanism that locks the hold means in a case where an operation request to the source for running is made and stops locking the hold means in a case where no operation request to the source for running is made.

3. The electrically driven vehicle according to claim 1, further comprising drive means that drives the hold means to hold the power generation unit in the state in which the power generation unit is installed in the electrically driven vehicle in a case where an operation request to the source for running and stops holding the power generation unit in the state in which the power generation unit is installed in the electrically driven vehicle in a case where no operation request to the source for running is made.

4. The electrically drive vehicle according to claim 1, wherein the hold means includes a lever or cover that blocks the power generation unit from passing through an opening of the electrically driven vehicle when the power generation unit is removed from the electrically driven vehicle, and thus holds the power generation unit to be installed in the electrically driven vehicle.

5. The electrically driven vehicle according to claim 1, wherein the hold means includes a bolt that fixes the power generation unit to the electrically driven vehicle, and thus holds the power generation unit to be installed in the electrically driven vehicle.
