The difference between electric trucks and fuel trucks

What is the difference between electric trucks and fuel trucks?

Trucks can be divided into electric trucks and fuel trucks according to different energy types. The main differences between electric trucks and fuel trucks are:

1. Suitable for different application scenarios

Pure electric trucks are mainly used for urban short-distance transportation. The application scenarios are limited mainly by the cruising range that current pure electric truck battery technology can provide when considering the core load and dead weight.

It’s about two to three hundred kilometers, and there’s also the charging time. Fast charging also takes about 1.5 hours. For long-distance transportation, fuel trucks are mainly used.

2. Different internal configurations

For traditional fuel trucks, the engine is the core, the heart of the truck, while pure electric trucks are driven by electricity rather than engines, so there are almost no engine-related parts, such as engines, clutches, fuel tanks, fuel pipes, Fuel pump, fuel injection device, intake and exhaust pipes, intercooler, exhaust gas purifier, muffler, etc. Pure electric trucks have greatly reduced parts, replaced by some electrical components, such as motors that use electricity to generate rotational force, batteries that store electricity, controllers and chargers that regulate electrical input and output, etc.

3. Different noise levels

The engine of a fuel truck works by burning fuel. It compresses a mixture of gasoline or diesel and air and burns it like an explosion. It produces a lot of force, a loud sound, and vibrations. The motor of a pure electric truck rotates using the principle of electricity generating a magnetic field. It can generate rotation force very quietly without burning, and has the advantages of being quiet and less vibration. In actual driving, electric trucks still make a metallic sound, which is the sound made when the controller adjusts the power of the electric motor, but it is smaller than the noise of the engine.

4. Batteries have different functions

Both electric trucks and fuel trucks are equipped with batteries, but the functions of the batteries are different: fuel trucks are generally 12v or 24v lead-acid batteries, which require a starter to start the engine, and it is the lead-acid battery that makes the starter rotate. In addition, lead-acid batteries are used to start various appliances such as headlights, wipers, air conditioners, stereos and power windows in cars. The amount of electricity released by lead-acid batteries is also

It is only enough to start the electrical appliances in the car, but it cannot drive the entire car. What determines the longest distance an electric truck can travel continuously is the capacity of the battery. The electric truck uses the power of the battery to start the vehicle.

The motor drives the car with its rotational force, and the controller regulates the flow of electricity from the battery to the electric motor, allowing it to increase or decrease the speed of the car.

5. Different torque output methods

After the engine is started, the fuel truck will be in an idling state, with a very low speed and a very small torque. When the accelerator pedal is pressed and the speed gradually increases, the torque will also gradually increase. When the speed reaches a certain value,

Torque increases to a maximum value, after which it gradually decreases even as the revs increase. The electric motor does not have an idling state. When the accelerator pedal is depressed and the electric motor starts to rotate, it can generate a large torque, that is, the force generated is the maximum. Because of this, the electric motor can eliminate the need for a transmission that relies on a combination of large and small gears to increase rotational force. It can be said that pure electric trucks can be used without a transmission, but for conventional electric motors, at medium and low speeds, the torque of the motor is very sufficient, but at high speeds, the torque of the motor will drop a lot. When considering the entire vehicle, In view of the power and economy, most pure electric light trucks on the market now tend to use motors plus electric motors.

Upper two-speed transmission. Pure electric trucks have very low gear requirements for transmissions.
