How to wire the range extender of the electric gas car?

Because the cruising range of low-speed electric four-wheeled vehicles is still relatively limited, can not fully meet the daily travel needs of the public, if you want to increase its cruising range, you can install a range extender, in order to increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and realize the freedom of travel, no longer due to the lack of power halfway and difficult.

The range extender can be purchased directly from the manufacturer, and the manufacturer will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a large manufacturer and a big brand to have a comprehensive guarantee of quality, performance, technology, after-sales and so on, otherwise if it is a small workshop-type manufacturer, it is easy to break and there is no guarantee in all aspects.

Recommendations for the use of range extenders:

It is not recommended to start the range extender when the battery is full, and it is generally recommended to start it when the battery is only 30%-40%. There is no particularly good effect when starting when the battery is full, in order to be environmentally friendly, it is recommended to start the range extender when needed, battery pollution is more serious than exhaust gas pollution, and protecting the battery is to protect the environment. It is not recommended to use it when the battery is not a little charged, the range extender is electric when it starts, and it may not catch fire when the battery is not charged at all.

Summary. 1.The range extender start controller start line is the positive pole.

The black and red wires are the power supply lines of the controller, and the thin red line is the boot line, after the voltage is obtained by this line, the controller will be turned on, and the controller will output voltage to start the motor by pressing the start button. The specific physical wiring diagram is as follows:

The red button in the picture above is the flame-out button, which has nothing to do with the controller and comes with the gasoline engine. The green button is the start button, which is directly connected to the controller start cable.

How to connect the range extender starting cable.

1.The starting line of the extended range start controller is the positive black and red two wires for the controller power supply line, and the thin red line is the boot line, the controller is powered on after the voltage is obtained by this line, and the controller will output voltage to start the motor by pressing the start button. The specific physical wiring diagram is as follows:

The red button in the picture above is the flame-out button, which has nothing to do with the controller and comes with the gasoline engine. The green button is the start button, which is directly connected to the controller start cable.

I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

By starting the controller, the direct current is converted into three-phase alternating current, and then the gasoline engine is started through the power generation coil.

1. Remove the rear seat of the electric vehicle.

2. After removing the seat, find the controller.

3. Take out the controller.

4. Disconnect the wire of the electric door lock.

5. Find the negative pole of the controller.

6. Connect the black wire on the range extender with the negative black wire of the controller.

7. Connect the red wire on the range extender with the electric door lock wire of the vehicle, and the operation is completed.

The principle of electronic starting range extender for electric vehicles:

An electric vehicle, electric bicycle, electric motorcycle with ground charging and on-board power supply function. Its power system consists of a power battery system, a power drive system, a vehicle control system and an auxiliary power system (APU).

When the battery is sufficient, the power battery drives the motor to provide the driving power demand of the whole vehicle, and the engine does not participate in the work at this time. When the battery power is consumed to a certain extent, the engine starts, and the engine provides energy for the battery to charge the power battery. When the battery is sufficient, the engine stops working again, and the motor is driven by the battery to provide the whole vehicle drive.

The electric vehicle lecture hall tells you whether the electric vehicle range extender has a range extender function and what is the principle?
