What are the advantages and disadvantages of electric cars?

Advantages: 1, lower cost later. 2, quiet and fast ride experience. 3, electric cars are truly zero-emission. 4, electric cars are more suitable for car rental mode.

Disadvantages: 1, the infrastructure is not perfect. 2, the range is still a problem. 3, power generation is not zero emissions. 4, fewer choices of car models.

The biggest advantage of electric vehicles is that they can greatly reduce fuel costs. Even if drivers don't fully utilize the electricity and mix it with fuel, the average fuel cost per mile is only a few cents. Therefore, the savings in fuel costs would be substantial. The motor operates at a much lower noise and vibration level than a conventional internal combustion engine. At idle and low speeds, electric cars are far more comfortable than conventional cars. As speed increases, tire and wind noise become the main sources of noise and return to the same level, a characteristic of electric vehicles that will undoubtedly help improve the vehicle's NVH performance.

By the limitation of battery capacity, the range of most pure electric vehicles is currently between 100-200 kilometers. In addition, the actual range will be discounted by weather, road conditions, batteries and other factors. Currently, most charging piles are slow charging piles. It takes 5-8 hours to fill up a car. Although it can be charged during the evening break, the disadvantage of slow charging of pure electric vehicles will be highlighted if there is an emergency.

Related information on EV maintenance is as follows:

1. The key to maintaining a pure electric vehicle is to take good care of its three electric systems, especially the power battery. In addition to the three electric systems, other aspects of maintenance and traditional fuel vehicles are not very different.

2, fast charging is harmful to the power battery. After all, it is a high-current charging. Therefore, the replenishment strategy for pure electric vehicles should be based on slow charging, supplemented by fast charging. If there are charging pile installation conditions at home, it is best to charge as you go.

3. Reducing the frequency of fast charging is a way to minimize the occurrence of power cell overcharging, and maintaining good driving habits is a way to try to avoid the problem of power cell overcharging. For example, in normal driving, try not to accelerate and decelerate rapidly, do not high-speed racing, that is, to minimize the problem of power battery over-discharge.
