Isn’t the extended-range car suitable for running at high speed？

With the coming of the May Day holiday, more and more new energy troops have joined the ranks of long-distance travel, but it is inevitable to replenish energy for long-distance travel, and the lower the energy consumption, the longer the battery life and the fewer times of recharging. Therefore, the lower the energy consumption and fuel consumption of new energy vehicles is also something that must be considered for long-distance travel, and it should be divided into two situations. Pure electric vehicles have low energy consumption and less charging times, which is not only convenient and fast, but also does not need to compete with others for charging guns at high speed. For hybrid vehicles, not only the city should save fuel, but also the high-speed vehicles should save fuel. After all, no one wants their "new energy vehicles" to consume more fuel than traditional fuel vehicles. Today, we will start with the energy consumption of various new energy vehicles and summarize the high-speed energy consumption performance of four types of new energy vehicles.

Pure electric vehicles are also divided into high and low energy consumption

High-speed working conditions are relatively high energy consumption for pure electric vehicles, so the battery life of many electric vehicles under high-speed working conditions will be discounted, and even the loss of some vehicles is more exaggerated, but pure electric vehicles are also divided into high and low energy consumption, so which electric vehicle is more energy-saving? First of all, there are models with advantages in algorithm and electronic control motor. Tesla is an electric vehicle with good high-speed energy consumption performance at present, mainly because its algorithm is excellent and the electronic control motor is advanced. Of course, many domestic models also perform well in this respect, so I won’t give an example one by one.

In addition, there are pure electric vehicles with gearboxes. At present, such electric vehicles are relatively rare. Typical representatives are Porsche taycan, Lotus Eletler+,SAIC MarvelR and Audi e-tronSportback. These vehicles are all high-end models, and they all adopt 2AT gearboxes, which can shift gears at high speed and reduce high-speed energy consumption. In addition, the high-speed energy consumption of new energy vehicles with light weight and low drag coefficient is also excellent.

Plug-in hybrid also has two poles.

At present, there are two technical routes for plug-in and hybrid vehicles in China, one is the E-CVT direct drive scheme headed by BYD, and the other is the multi-gear DHT scheme represented by Great Wall Geely. The high-speed energy consumption performance of these two schemes is also different. The faster the direct drive scheme is, the higher the energy consumption is, especially in the case of heavy vehicles, and the high-speed fuel consumption is much higher than that in urban areas. The more gears in the multi-gear DHT scheme, the lower the high-speed energy consumption, which is the difference between the two schemes.

Extended range hybrid high-speed fuel consumption is the highest

The extended-range hybrid has a simple structure, and the driving quality is almost the same as that of pure electric vehicles. However, due to the lack of direct-drive function, the energy consumption of extended-range vehicles under high-speed conditions is terrible, which is completely opposite to that of conventional fuel vehicles under high-speed conditions. Especially, some extended-range vehicles with relatively large vehicle weight, such as the ideal L series, can achieve high-speed fuel consumption of about 9L kilometers, even higher than that of fuel vehicles of the same size, comparable to some full-size SUVs with V8 engines. This is mainly because the engine does not participate in direct-drive and can only do its best.

Summary: At present, the energy consumption performance of most electric vehicles on the market at high speed is average, while the energy consumption performance of gearboxes in hybrid models is better than that of direct-drive models, while the extended-range models have the highest energy consumption at high speed, which is the least recommended for long-term high-speed use. Therefore, you should be clear about your own use needs and buy cars according to actual needs. (Text/Youshi Automobile Haoyang)
