Are new energy vehicles suitable for autonomous driving?At present, new energy vehicles are mainly divided into two types: 1 pure electric vehicle and 2 plug-in hybrid electric vehicles: can these two new energy vehicles achieve long-distance autonomous driving?Which is the most suitable?I'm going to analyze it next. The comprehensive cost of using new energy vehicles.
Generally speaking, new energy vehicles consume about 2 to 3 cents per kilometer, and they can travel about 200 kilometers on a single charge. The fuel consumption of the car is about 6 to 7 cents per kilometer. It seems that the savings of new energy vehicles are less than half. The crux of the matter lies in the battery of new energy vehicles.
The batteries of new energy vehicles are mainly ternary lithium batteries or lithium iron phosphate batteries. The number of charging cycles is about 1000-2000 times. If it is a PHEV, it can travel about 100,000 kilometers with pure electric power. Plug-in hybrid passenger cars have a lifespan of 5 to 10 years, while EV batteries have a lifespan of 4 to 6 years.
Let's assume 5 years. After 5 years, new energy vehicles will either need to replace the battery or replace the car. How much does it cost to replace the battery?It's almost more than 40,000 yuan, which is about the same as spending 50,000 yuan to buy a new domestic car. Should I buy a new car or replace the battery?If it is a Stirling electric car, its battery is more expensive and the lifespan is also 5 years.
It is not recommended to use a battery electric vehicle for long-distance autonomous travel. While it's convenient to have charging stations on the road, it's not recommended for long journeys at this time. After all, even if there are many charging stations, how long is the charging time?Although some models advertise fast charging to reach 80% in half an hour, the cost of fast charging is very high and not worth it.
Fast charging will only be an option in case of emergency. Then, if the charging is slow, it can last for about 10 hours. Oh my God, what kind of swimming is this?Who can stand it?I wanted to go out for a walk and have fun, but I was in a bad mood. Rechargeable batteries are actually the main factor limiting the travel of new energy vehicles.
However, in recent years, most places in the country have the charging conditions, which is also more convenient. When we travel long distances, we need to plan our routes in advance and find charging points, as they are not available everywhere. Just like I refuel every time I go out, new energy vehicles must also be fully charged before going out to prevent halfway trucks.
Most hotels now have dedicated charging stations for new energy vehicles, but it's best to make an appointment in advance and check before check-in, because resting at night is also a good time to recharge. If you want to travel long distances, but are on a high-speed arterial road, and the place you are going to is a regular tourist town or a sparsely populated area, it is easier to find a charging station.
The distance between the two destinations can also be controlled at about 70% of the remaining power, which I don't think is impossible. If you like to travel to places where there are fewer people and even gas stations are hard to find, I think you should consider a regular fuel vehicle, or a vehicle that can travel a thousand kilometers with a full tank of fuel. Energy vehicles are more reliable.
New energy plug-in hybrid electric vehicle: It is a hybrid propulsion system that includes a gasoline engine and an electric motor. You can choose between pure electric drive mode or hybrid drive mode. At present, most plug-in hybrid vehicles in the domestic market have a pure electric range of at least 50 kilometers. As soon as the energy is consumed, the fuel engine starts to step in.
It can drive the car while taking care of the need to charge the battery and generate electricity. But it's domestic. Hybrid technology is not mature enough compared to Japanese hybrid technology. Once there is no electricity, the fuel consumption will be very high (depending on the person, the maximum fuel consumption per 100 kilometers can be about 10 liters of oil), so it is compared to new energy plug-in hybrid vehicles. Plug-in electric vehicles are better suited for urban or short-distance transportation and are more economical than gasoline vehicles when powered by electricity.
In general, new energy pure electric vehicles are suitable for autonomous driving travel in terms of range and cost saving. In order to save money, it is definitely right to choose a new energy electric vehicle. For friends who are relatively wealthy and not short of money, the choice depends entirely on personal needs and hobbies.
