Why do companies rarely produce extended-range plug-in electric vehicles? How is the power of extended-range plug-in electric vehicles?

Many car enthusiasts may have noticed that there are very few automobile companies producing extended-range plug-in electric vehicles. Compared with hybrid vehicles and pure electric vehicles, extended-range plug-in electric vehicles should consume less fuel. Why do so few companies do this? In fact, it is because the losses caused by the secondary energy conversion of extended-range plug-in electric vehicles are very large and the utilization rate is not high.

Why do companies rarely produce extended-range plug-in electric vehicles?

It is easy for major car companies to make extended-range electric vehicles. There is no technical barrier at all. Even Shandong's elderly mobility scooters have been made into "oil-electric hybrids", which is also a type of extended-range electric vehicles. Even three-wheeled vehicles have "extended-range versions".

Of course, this extended-range electric vehicle is just a simple assembly without a sophisticated control system. Therefore, users report that the fuel consumption is extremely high and the noise is huge. In fact, this is also the weakness of extended-range electric vehicles. Even with a perfect power management program, it cannot change the loss caused by the secondary conversion of energy. It can only reduce the loss, but it cannot achieve the high utilization rate of fuel vehicles!

How is the power of extended-range plug-in electric vehicles?

When the range extender is turned on after the battery is depleted, the vehicle power will also be discounted. After all, the power of the range extender cannot be several times greater than that of the electric motor. When the electric motor starts instantly, the power will increase exponentially. Although there is a battery to assist in discharge, the discharge current will also decrease when the battery power is low. In fact, in order to further reduce the fuel consumption of the range extender and reduce the vehicle's own weight, the power of the range extender will not be too high. It can be seen on several mass-produced models that the power of the range extender is much smaller than the power of the electric motor.

Does the extended-range plug-in electric vehicle consume a lot of energy?

When the engine drives the electric motor to generate electricity, some energy will be wasted. When charging the battery, some energy will still be wasted. When powering the electric motor, some energy will also be wasted. After multiple conversions, energy can only become lower and lower, not more and more. This is the law of conservation of energy. Imagine that the internal combustion engine directly drives the wheels without two conversions. Wouldn't the efficiency be higher? In fact, this is also the case. Hybrid vehicles only use the electric motor drive mode when driving at medium and low speeds, and the engine directly drives the vehicle when driving at medium and high speeds. In this way, the engine utilization rate can be maximized and a lower fuel consumption can be obtained.

Extended-range electric vehicles are pure electric vehicles, electric bicycles, and electric motorcycles that are equipped with ground charging and onboard power supply functions. Their power system consists of a power battery system, a power drive system, a vehicle control system, and an auxiliary power system (APU).

The extended-range electric vehicle uses the vehicle controller to complete the operation control strategy. The battery pack can be charged by a ground charging pile or an on-board charger, and the engine can be fuel or gas-powered.
