How much is a knife and an electric car? Is it expensive?

By September 2020, the price will be around 2000 yuan. Not expensive.

Electric vehicles are relatively simple in structure, convenient to maintain and durable, so their operation is relatively simple, and their natural service life is longer than that of other vehicles using fuel.

After the electric vehicle is used, it can reduce the pollution to the environment and ensure that there is no exhaust gas during the use of the electric vehicle, which is better than the traditional vehicle. For example, the sources of electric vehicles come from all aspects, and hydropower, wind energy, solar energy and nuclear energy can all be converted into electric energy, which can effectively avoid the phenomenon of air pollution.

Precautions:

The battery will be overcharged when it runs in high temperature season. With the increase of temperature, the activity of active substances increases, the reaction is full and intense, and the anode oxygen evolution potential and cathode hydrogen evolution potential decrease. This leads to fast reaction speed, large charging current and low charging voltage. In order to prevent the charging voltage from being too high, the battery temperature should be reduced as much as possible to ensure good heat dissipation and the original charger should be used.

When using an electric car in summer, we should pay attention to the safety of the battery as much as possible, because the weather is hot and the battery is always heating during the use of the electric car, so the safety hazard of the battery is a very big problem, which may easily lead to the spontaneous combustion of the battery. Be sure to pay attention to the ventilation and heat dissipation of the battery to avoid the battery of the electric vehicle being exposed to the sun.
