in the development history of extended-range electric vehicles, "taking off pants to fart" has always been a criticism of this type of new energy vehicles by some people. the reason is very simple, that is, extended-range electric vehicles generate electricity through the range extender, and the generated electricity drives the wheels to rotate. many friends said that the internal combustion engine + gearbox directly generates driving force, which is not much simpler than the extended-range type going around in a circle, so why do we still buy extended-range electric vehicles?

first of all, we need to correct a point of view, that is, the extended-range electric vehicle is essentially an electric vehicle, so the process of burning oil, generating electricity, and then driving is essentially not comprehensive! since the essence of the extended-range electric vehicle is an electric vehicle, the core advantages of this type of new energy vehicle are the same as those of electric vehicles. the smooth operation of electric vehicles is an advantage that almost all fuel vehicles do not have, and the acceleration ability and acceleration sensation of electric drive models are quite good.

on the other hand, as electric drive models, electric vehicles and extended-range electric vehicles are the best carriers for realizing high-level intelligent driving. from the current situation, we can see that truly high-level intelligent driving systems basically appear in pure electric models and extended-range electric vehicles, such as huawei's ads 3.0, ideal ad max, xiaopeng, weilai, and tesla's intelligent driving systems.

the reason is actually very simple, because fully electric drive vehicles are more conducive to the transmission of intelligent driving system signals and power signals, unlike fuel vehicles and plug-in hybrid vehicles, which have to go through multiple processes such as intelligent driving system, engine computer, engine, gearbox, wheel end, etc., which is not conducive to the realization of high-level intelligent driving.

so even if the extended-range electric vehicle has an engine, it only serves as a "power bank" because in addition to the range extender, the extended-range electric vehicle also has a power battery. and because the structure of the extended-range electric vehicle is relatively simple, the size and capacity of the power battery of many extended-range electric vehicles are still relatively large. at present, the pure electric range of many extended-range electric vehicles exceeds 200 kilometers, and some even reach 300 kilometers.

therefore, in many cases, the extended-range electric vehicle is a pure electric vehicle, especially for users who use the vehicle between home and work, who basically use it in pure electric driving mode, and the range extender is not started at all. when driving long distances or at high speeds, in addition to pure electric driving, the range extender can also serve as a "power bank", that is, starting the range extender to generate electricity to drive the vehicle to go further.

so in essence, the engine on the extended-range electric vehicle, that is, the range extender, has never been the protagonist, but only a supporting role. in this case, the extended-range electric vehicle is not a fuel vehicle. in other words, it is not based on burning oil. since it is not based on burning oil, the range extender is only an auxiliary to extend the battery life in occasional situations, and the so-called "taking off pants to fart" criticism does not exist.

in short, many people buy extended-range electric vehicles because they can run on both oil and electricity, have the smoothness of pure electric vehicles, and have the basic conditions of advanced driving assistance capabilities. at the same time, they can also extend the driving range by starting the range extender. few people will drive extended-range electric vehicles as fuel vehicles! of course, electric drive models like nissan e-power that do not have pure electric range can really be said to be "taking off pants to fart".
