What is an extended-range power car？

First of all, let’s take a look at what an extended-range car is.

It is an electric vehicle equipped with on-board auxiliary power generation system (range extender), which consists of engine, generator and controller. There is no transmission connection between the engine and the vehicle drive system, such as a transmission shaft, and it is divided intoPure electricity and extended rangeIn the two working modes, the wheel driving force is independently provided by the motor, and the engine does not directly participate in the power driving, and the driving energy of the automobile is always electric energy.

When the vehicle-mounted rechargeable energy storage system can’t meet the requirements of vehicle endurance, the range extender provides electric energy for the power system, realizing a longer endurance and a more convenient way of energy supplement.

In a sense, the extended-range and plug-in hybrid vehicles are very similar in use, and both can be "oil and electricity" according to the needs of the vehicle.

What’s the difference between it and plug-in hybrid car?

The difference between plug-in hybrid vehicle and extended-range hybrid vehicle mainly lies in power source, engine function, fuel consumption and battery charging method.

Extended range mixingThe motor driven by the power battery drives the vehicle to move forward,The engine only serves to charge the power battery.,Do not directly provide power; butPlug-in hybridUnde that condition that the battery of the vehicle is insufficient, it canPowered directly by the engine.. The extended-range hybrid engine is only responsible for generating electricity for the vehicle, and the generated electric energy directly supplies power to the driving motor and also charges the battery. When the battery is fully charged, the internal combustion engine can stop working, and the battery directly drives the motor to push the vehicle forward; butPlug-in hybridConsists of two power systems,Motor drive and engine drive,The engine not only provides power, but also drives the car when the battery is dead.

Advantages of extended-range mixingIt has the advantages of low driving noise, long battery life, smooth power output, simple maintenance and money saving, butdisadvantage​It is weak power, low energy conversion efficiency, and more oil consumption when running at high speed;

Advantages of plug-in hybridIt can realize the free switching of the three states of "pure electricity, pure oil and oil-electricity mixture",disadvantage​When the power is insufficient, the fuel consumption rate is relatively large.

What are the common extended-range cars?

The fire of new energy vehicles will inevitably lead to the development of new vehicles with extended-range power. Our common extended-range power vehicles include Changan extended-range version, extended-range version, and so on.

Chang ‘an ShenlanSL03 Extended Range Edition

The powertrain composed of 1.5L engine and motor can achieve a cruising range of 200km in pure electric mode, and the comprehensive cruising range is 1200km.

Lantu FREE extended range edition

The 1.5T engine with the maximum power of 80kW is used as the range extender of Lantu FREE, and it is equipped with front and rear dual-motor four-wheel drive system, which can break 100 in 4.3 seconds at the earliest, making it a sports car in SUV. According to different versions, the pure electric cruising range of 140km and 205km can be realized respectively, and the comprehensive cruising range can easily exceed 960km when the energy is sufficient.

Ideality L7

Using 1.5T engine and front and rear dual motors as the hardware assembly of the ideal L7, the acceleration of 5.3 seconds to break 100 meters is still far from that of Lantu FREE, but it can fully meet the power requirements of most consumers. In addition, according to the official statement, the comprehensive cruising range can exceed 1300km.

Regarding ideals, during the past May Day period, a pure electric vehicle owner started the "curse street" mode in the circle of friends: I am really speechless. Do you have money to buy a car and no money to refuel? Every service area has an ideal to charge in the charging pile.

It is undoubtedly a farce for pure electric car owners to "denounce" the ideal car owners for occupying high-speed charging resources.

The dissatisfaction of these pure electric vehicle owners mainly comes from three points:

Whether to say it or not, this speech is still a bit excessive.

First of all, saving is a virtue whether you have money or not. Compared with refueling, charging can reduce the cost of a single trip, and it not only contributes to protecting the earth, but also fully promotes the traditional virtues, killing two birds with one stone; Secondly, it is the owner’s freedom to choose whether to drive by electricity or by burning oil; Finally, neither the law nor the charging pile operator has made any restrictions on the energy types of vehicles that come to charge. As long as it is normal business hours, any vehicle that supports charging enjoys the right to use charging piles equally.

As the most scarce resource during the long vacation, the development of high-speed charging piles is not perfect at present, but the freedom of car owners’ choice should be respected and the first-come-first-served rule should be observed. For example, an ideal extended-range car owner set off at full power, traveled 50 kilometers on pure power, decided to recharge, and willingly waited for a few hours to save dozens of dollars. There must be some pure electric car owners who don’t like it, but first come first served is the rule.

As a kind of new energy vehicle, extended-range power vehicle has obvious advantages under the premise of no great breakthrough in power battery technology. Compared with pure electric vehicles, extended-range electric vehicles are equipped with smaller power batteries, which are naturally less affected by the rising prices of raw materials and production costs of power batteries, which also provides a foundation for covering more consumers. In addition, under the condition that some new energy vehicles feel bad in winter, it fills the gap in the promotion of new energy vehicles in relevant areas, and can also be used in areas where the charging infrastructure is not perfect enough, which can play a positive role in promoting the growth of new energy vehicle consumption market.
