Slow charging, more charging, talk about pure electric vehicle charging those things?

For pure electric vehicles, charging is an important way to replenish energy. Currently, there are two types of charging piles, one is fast charging pile and the other is ordinary charging pile. Charging with a fast charging post is relatively short and can effectively improve the convenience of using a car, while charging with an ordinary charging post is relatively long. However, as of now, the number of public **** charging piles in China is still relatively small, and most of them are still dominated by ordinary charging piles, that is, private charging piles.

According to statistics, as of December 2019, the sum of charging piles operated by China's public **** and private charging piles was about 1.219 million units. And as of June 2019, the number of pure electric vehicles in China has reached about 2,810,000 units, and the large difference in the number of vehicle piles has constrained the development of China's pure electric vehicle industry. Another thing to note is that as a car owner, although you can rely on fast charging piles for charging, long-time charging will cause some damage to the battery.

Because the fast charging pile is generally through the increase in current to achieve the purpose of rapid charging, and for the current pure electric vehicles equipped with batteries. Charging with high current for a long period of time can lead to increased chemical reactions, which in serious cases can lead to thermal runaway. And for the power battery, charging and discharging reaction is actually the internal lithium ion movement process, the current increases, the embedded and embedded out of the speed will be affected, then for the corresponding battery service life is also affected.

In addition to the low number of charging piles, as well as the use of fast charging will pose a security threat, the current charging piles in our country still exists in the layout of the situation is not perfect. For example, many charging piles are now located in the first and second tier cities, and for some third and fourth tier cities or small counties, there are no charging piles at all. And charging piles need regular maintenance, many charging piles due to maintenance is not in place, resulting in charging and can not achieve the purpose. And because the layout is not perfect, resulting in low utilization of charging piles, all of these constraints on the development of China's pure electric vehicle industry. I don't know what people think?
