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.

The increase of power battery capacity of new energy vehicles: the fast charging performance of the power battery determines the ceiling of the fast charging pile. The development of DC fast charging pile requires the cooperation of the power battery. At present, battery manufacturers such as Ningde Times and BYD are trying to improve the energy density of batteries to enhance the endurance. In 2020, the energy density of new pure electric passenger vehicles has basically exceeded 150Wh/kg, and the average endurance mileage has exceeded 400km. The improvement of the endurance mileage of new energy vehicles has improved the practicability of high-power DC public piles, and accelerated the preference of vehicle owners for DC piles, which is the key reason why DC piles will become the choice direction of public piles in the future.

After the completion of charging piles in some places, operation and maintenance become a problem. On the one hand, the number of urban public charging facilities is small, and the distribution is uneven and unreasonable; On the other hand, the management service platforms of the charging infrastructure construction and operation units have not yet achieved interconnection, nor has there been a unified, open and convenient payment platform, which has caused great inconvenience to charging infrastructure users. In addition, in the development process of new energy vehicle industry, there is a widespread problem of focusing on vehicles rather than charging infrastructure. In addition, the national early support policy is mainly aimed at new energy vehicles and does not cover charging facilities. Except for a few cities, most cities have no local subsidies. "This leads to the coexistence of vehicles without piles and piles without vehicles." Moreover, charging infrastructure construction involves urban planning, construction land, distribution network construction and transformation, property management and other aspects, and it is necessary to coordinate multiple competent departments and relevant units in the implementation process.

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

In fact, in order to effectively develop the new energy vehicle industry, in addition to the problems exposed in the construction of charging piles, such as difficult site selection, power connection and property coordination, the integration of infrastructure resources, the unification of public charging facilities information platform, the standardization of charging interfaces, and the billing and settlement in the charging process also need to be solved. The charging infrastructure of new energy vehicles is a new type of urban infrastructure. Its construction is a systematic project involving land, power grid, electricity price, mechanism and many other links, which is also the reason why the charging infrastructure construction is relatively difficult. However, as long as the relevant parties meet each other and reach consensus, instead of talking to themselves and going their own way, these problems will eventually be solved.
