According to the new national standard, the charging plug standard of different models in the future is the same. Xu Xinchao said, "Although there will be differences in voltage and power, theoretically it can be used in the same charging point. In addition, the new national standard attaches particular importance to the safety of the charging pile, which has always been the top priority. The standardized charging pile of new energy vehicles will automatically cut off power after charging, making breakthroughs in insulation and avoiding electric shock in rainy days, so as to avoid unnecessary dangers for new energy owners during charging.

Not only does China attach importance to the development of new energy charging equipment, foreign new energy companies are developing more rapidly, and French oil giant Total is also actively building charging equipment. In the early years, Total acquired Saft, a battery manufacturer. This company originally produced power batteries and provided automotive batteries for many automobile manufacturers. And some foreign companies have even developed wireless charging technology. They transmit wireless energy through magnetic induction between the charging coil and the receiver. The charging coil is buried under the ground. When it needs to be charged, just drive the car to an appropriate position to charge. New energy vehicles are very popular in recent years. Because of the environmental protection of new energy vehicles, many countries advocate new energy vehicles, and many people are interested in new energy vehicles. The New Energy Vehicle Technology Analysis has relevant content. Obviously, the trend of fuel vehicles has gone.

What should be paid attention to when charging electric vehicle batteries? When the electric vehicle starts and goes uphill, it is necessary to avoid emergency braking and acceleration as much as possible, because large current discharge will be formed during this process, which will damage the performance of the battery. There are also two points that need special attention when stopping for a long time. 1. Parking without power supply should be avoided: unlike traditional gasoline vehicles, electric vehicles have their own "unique taste" for the state of vehicle parking. If the "hungry stomach" is used too long, it will "rebel". When the electric vehicle is parked in the case of power loss, the battery is prone to sulfation, blocking the electric ion channel, resulting in insufficient charging and declining battery capacity. 2. Deep discharge shall be carried out regularly: when the electric vehicle is almost out of power, undervoltage protection will automatically occur, but during this process, its voltage is unstable, and it will also be up and down, causing repeated undervoltage protection status

The charging pile industry comes with the development of new energy vehicles. In 2020, the charging pile will be included in the new infrastructure and written into the government work report, which will become the precondition for developing new energy vehicles, stimulating new consumption demand and helping the industry upgrade. Under the exploration of new business model and the guidance of a new round of policies, new channels for the development of charging piles have been opened, ushering in new opportunities. The charging pile industry chain is divided into supply terminals such as equipment manufacturers and power suppliers, operation terminals such as operators and new energy vehicle enterprises, and support terminals such as map navigation and payment functions. The core link is the operation end, which is responsible for the investment, construction and operation management of the charging pile. At present, Chinese funded enterprises, private capital and vehicle enterprises are all involved in the operation.
