As early as the birth of cars, electric cars have already appeared, but due to technical problems, has not been much development.
However, with the increasingly serious environmental problems in recent years, electric vehicles not only re-enter people’s vision, but also attract attention from the government and industry.
By the end of 2017, China had promoted more than 1.8 million new energy vehicles, according to public data.
It sold 32,000 units in January 2018 and 34,000 units in February 2018.
With the help of the policy, China’s new energy vehicle market has gradually become a climate.
So, is new energy electric vehicle good or not?
In the past evaluation of a car is good, we know that the most important thing is to look at the three parts of the car: engine, gearbox and chassis, because these three parts occupy most of the material cost of the car, and a car’s research and development, the three parts of the technical content is the highest.
The old driver can roughly judge the grade of this car through the configuration of engine, transmission and chassis.
For electric vehicles, there is also a crucial “three”, that is we often hear the three electric system, which is the core of electric vehicles, including the battery, motor and electric control system.
Here, consumers are most familiar with batteries.
According to the survey, the first factor that consumers consider when buying an electric car is range, followed by performance and design.
It is not difficult to understand that when a new car comes on the market, the first thing that car companies mark out is the range, but the range of electric cars is not the final word.
Batteries — Power Source Batteries are the electric equivalent of the fuel tank in a conventional car.
As long as it is powered by electricity, the larger the battery capacity, the better the battery life.
Some car companies by increasing the cell size and cell number to achieve the effect of current capacity, but in body structure, the more battery means of physical space is larger, and the wind resistance coefficient of electric cars per 0.01 CD increased, more than 5 km range will reduce, then it is also an important factor restricting the battery capacity battery weight.
