Are the batteries of new energy vehicles safe? Ready to buy a new energy car to head off trouble, ten days ago. A stolen Tesla electric car was split in two after colliding with other vehicles during a police chase, foreign media reported. After several years of development, new energy vehicle power technology has made great progress, the battery, the material itself has flame retardant technology, fire risk is greatly reduced. But Xu Yanhua, deputy secretary-general of the association, said that, like traditional cars, the magnetic poles would not be washed away and burst.

When people think of the power of lithium batteries, they usually think of lead batteries used in electric bicycles, and the substandard recycling has been blamed for heavy metal pollution. So will electric car batteries bring new pollution?

Lithium-ion batteries for new energy vehicles have passed rigorous tests at the national level, and all chemicals can be recalled. Byd auto spokesman Li Yunfei said. Compared with electric bicycle batteries, new energy vehicle batteries have a higher recycling threshold, which is generally recycled by automobile companies, but the standard recycling still needs supporting policies and regulations.

Pure electric cars have a 35 percent lower range than in colder climates. In cold weather, it dropped 57 percent, less than half the normal range. Battery capacity: The battery capacity of an electric vehicle is usually measured in kilowatt-hours (KWH). The larger the battery pack, the greater the car’s energy storage capacity and the greater its pure electric range.

Driving Distance:

Driving distance refers to the maximum driving distance of a fully charged vehicle, and this value is for reference only. Driving mode, climate, the number of electric equipment and other factors will affect the driving distance of electric vehicles. Among them, the driving mode is relatively steep, the use of electric equipment as little as possible, adding a series of electric vehicles is very helpful, which also applies to the traditional power vehicles. But the impact of hot and cold weather on the range of electric vehicles is far greater than that of conventional vehicles. Research tests show that in hot weather, the range of pure electric vehicles is 35% lower than in cool weather. In cold weather, it dropped 57 percent, less than half the normal range.

Battery capacity:

The battery capacity of an electric car is usually measured in kilowatt-hours (KWH). The larger the battery pack, the greater the car’s energy storage capacity and the greater its pure electric range. However, the addition of batteries is bound to improve the quality of vehicles, affect the performance of vehicles, greatly increase production costs. How to strike a balance between distance, battery pack quantity and production cost has become a difficult problem for the development of electric vehicles.
