Which is better, the electric tricycle range extender, fixed throttle or electronic throttle

You have to change the carburetor, buy an autothrottle carburetor, there is the kind that can't get into the motor, so the controller also has to buy one, and that's it.

<>5kw low-speed electric vehicle range extender.

The fixed throttle of the range extender is the fixed speed (fixed frequency) model, and the automatic throttle is the frequency conversion model, which must be relatively better than the frequency conversion. Just like the difference between the frequency conversion and the fixed frequency of the air conditioner, the power saving of the frequency conversion is better than the fixed frequency, and the fuel saving of the same range extender frequency conversion is more fuel-efficient than the fixed frequency, so it is recommended to choose the frequency conversion. The power generation of the fixed frequency range extender is always kept unchanged, fixed, if it encounters an uphill situation, because it is a fixed frequency, if it can't go up, then it really can't go up.

The power generation of the frequency converter is to determine how much electricity is generated with the actual road conditions of the motor demand for electricity, such as the horizontal road surface when its power generation will be relatively small, when it encounters the uphill need to be driven by large current, it will increase the power generation to meet the driving needs of the motor, to ensure that the electric vehicle can go uphill smoothly.

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.

The throttle is used to control the throttle opening, the larger the throttle opening, the more air intake of the engine, the throttle is not used to directly control the amount of fuel injection in the engine, the throttle is in the front section of the intake manifold, the throttle is called the throat of the engine, and the throttle can control the air intake of the engine.

The electric tricycle collapse range extender has a variety of displacements, we commonly see a 170 top rod gasoline engine here, its circuit consists of a power generation coil, a rectifier and a starter, the start control part, the start and control are mainly divided into a manual control throttle and semi-automatic control throttle and fully automatic control throttle.

The automatic throttle starter is further divided into semi-automatic {semi-automatic mixing} and fully automatic control:

Semi-automatic control is controlled by the signal voltage of the handlebar, the starter has a separate signal line, which needs to be connected to the handle signal, when the handle is rotated, the signal voltage rises and burys, and the starter supplies power to the progressive motor on the carburetor to control the size of the throttle. The turnbar signal is proportional to the motor signal, and the larger the turnbar signal, the bigger the throttle.

This is a fully automatic starter, this must be dedicated to the car, it is automatically controlled by the voltage drop, when starting, when the car is driving, if it encounters a slope or heavy load, the battery voltage drop will automatically increase the throttle to restore the power to the manufacturer's set value. The greater the voltage drop, the greater the power generation.

When the battery pack is in a state of power loss, it is easy to cause insufficient power of the motor or frequent stalling of the generator.

The working principle of the electric vehicle range extender is:

A twin-cylinder engine with a rated power of 8 kW and a torque of 25Nm 3000r(min) at the operating point is used to drive a generator with a rated power output of 7 kW to supply power to the motor in the car. Generally, when driven by pure electric drive, the S18D range extender electric vehicle has a driving range of 100-145 km, and with the help of a range extender, the driving range of the car can be increased to 300 km.

Theoretically, the automatic throttle can control the amount of oil entering the engine according to the voltage and power level of the electric vehicle to avoid waste, so as to achieve the purpose of reducing fuel consumption and saving energy.

Theoretically, this is true, but in fact, because the types of batteries configured by electric vehicles and their working characteristics are very inconsistent, and the intelligence, precision and durability of the control module are not enough, it has a certain effect to achieve, but it is not ideal.

The disadvantage is that when the battery pack is in a state of power loss, it is easy to cause insufficient power of the motor or frequent shutdown of the generator.

Disadvantages: late start (the engine power is less than the motor, should be started early to reduce power consumption), early ignition (to avoid battery overcharge and reduce power generation), small throttle (to reduce noise and protect the range extender), low generator efficiency (the engine works in the non-economic speed zone when the throttle is small).

Advantages: Low sound, low fuel consumption, protection of the battery pack and controller (protection against overcharging, prevention of engine failure and high voltage output).
