In the environment of new energy development, why aren’t there many people buying pure electric vehicles as the backbone? In fact, the answer is very simple: the user is not a fool. Compared with fuel vehicles of the same level, electric vehicles have obvious shortcomings. Xiaomu mainly tells you from five directions. Please add to the shortcomings.

. The charging conditions are not popular enough

The favorite electric cars are first- and second-tier license plate restriction cities. These cities have huge parking space gaps. Car owners with independent charging conditions are among the very few, and those without conditions can only rely on public charging stations. Car owners who rely on public charging stations basically bought a father. When they go to a slightly farther place, they have to check in advance whether there are charging stations nearby. If there are charging stations, they have to worry about whether there are parking spaces. If there are parking spaces, they have to find a backup charging station in advance.

, and the charging pile is not cheap either. The electricity bill is basically around 1 yuan/degree, the service fee is between 0.5 yuan/degree and 0.8 yuan/degree, and the overall unit price is between 1.5 yuan/degree and 1.8 yuan/degree. According to the 15-km computer for mainstream electric vehicles with 100 kilometers, it will cost nearly 30 cents per kilometer. If it were winter, it would probably be more than that.

. Battery is greatly affected by low temperature

. Because of its characteristics, the charging and discharging speed of the battery will be significantly affected in a low temperature environment. BMS below 5 degrees will limit the charge and discharge current in order to protect the battery, it is basically half folded. At the same time, the kinetic energy recovery force is also reduced by 50% compared with the normal temperature, and the braking force is significantly reduced.

is prone to cause lithium ion crystallization under the sudden acceleration, causing irreversible battery loss. The most important thing is that the range is greatly shortened. For electric cars, which originally had fewer cruising ranges, low temperatures are really a killer. If the air conditioner and heating air is turned on in the car...

. The charging speed is slow

Electric cars usually have two charging ports: AC slow charging and DC fast charging, which is actually similar to mobile phone charging. Whether it is fast charging or slow charging, when the BMS reaches a certain value point (usually 80%), the charging power will gradually decrease in order to protect the battery. Therefore, even if it is fast charging, it cannot be fully charged in a short time. If you take a step back, it will not be charged at 80% of the battery per fast charging. According to the promotional information of the car company, it will take at least half an hour. If there is an urgent matter, it will really make people desperate. If it is winter, the charging speed will be reduced.

4. Running high-speed is too expensive to operate

Fuel vehicles have a term called economic speed. Economic speed is the speed of the engine under the highest efficiency operating conditions and is also the most fuel-efficient speed. Compared with urban vehicles, running high-speed can bring efficient operating conditions to fuel vehicles. This is because the range of efficient operating conditions of the internal combustion engine is small. However, the motor has a much larger operating range than the internal combustion engine. As the vehicle speed is faster, the greater the energy consumed by motor , and the range of cruising decreases in stages rather than linearly.

In addition, the energy density of the battery is much lower than that of gasoline. The highest energy density of the power battery is only 0.2KWh/kg, while the energy density of the gasoline is 12.8KWh/kg. Under high-speed cruising, the higher the energy density, the more obvious the advantage.

5, high price, low value retention rate,

, you can compare the prices of fuel versions and electric versions of similar cars on the market. You will find that the price of electric cars is tens of thousands more than the fuel version. If you say that these tens of thousands are similar to the fuel version in a few years, then let's take a look at the value retention rate in a few years, which can also be called residual value . According to the 2020 China Automobile Retention Rate Research Report, the average annual retention rate of the TOP10 fuel models of all levels is 48.2%.

Electric vehicle value retention rate is largely limited by battery capacity, which attenuates with the increase in usage time and mileage. According to the data on the value retention rate of pure electric vehicles, taking Tesla as an example, the value retention rates of the three models, Model 3, Model X and Model S, were 46.83%, 41.34% and 34.15% in the fifth year, respectively, but there is still a gap compared with fuel vehicles.
