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.

There are four main pain points: A. Battery standardization is too difficult. The separation of vehicle and electricity first requires the standardization of power batteries, BMS standardization, interface standardization, and software management standardization. Any vehicle upgrade must be compatible with the previous generation of products. Battery standardization is too difficult. Every car company wants to make its own electricity exchange standard. It is unrealistic for so many car companies to unify. B. The investment is large and the cost is high. The replacement of power needs to lay a large network, and the investment scale is far greater than charging. Build a power exchange network for a city to provide special tram exchange services. The cost can be recovered only after at least 6-8 years or even more. C. The deflagration hazard of the power plant is large, and the safety hazard is huge. D. It is difficult to improve the customer experience.

The charging pile body is mainly composed of human-computer interaction unit, control unit, metering unit and safety protection unit. The human-computer interaction unit mainly includes: pile, LCD touch screen, card reading module and charging plug; The control unit mainly includes: main monitoring and auxiliary module; The metering unit is electric energy meter; The safety protection unit includes: leakage protection switch, anti fall switch, emergency stop switch, overvoltage and undervoltage protection unit.

How to properly charge in the hot link when using the charging pile of new energy vehicles? 1. Take care of your electric donkey and don't let it get sunburnt: in hot summer, you often sweat, and the rechargeable battery often "gets high fever". Here, it is recommended that the owner choose a place with a parking shed or a barrier to cover the electric vehicle as far as possible, and don't let the electric vehicle be exposed to the sun immediately, which will endanger the service life of the vehicle. In addition, fire accidents are very likely to occur under high temperatures. 2. Do not "steam up and cook down": the temperature is already hot. If the electric car is exposed to the sun at the moment, but you are charging the car, the rechargeable battery will generate heat in the whole process of charging. At this time, all cars are in the "steam up and cook down" mode, and you will "deploy" carelessly. 3. The electric vehicle must also take a proper "rest". 4. The charging time must be well controlled.

DC piles are the inevitable choice of public piles in the future: at present, the proportion of public AC and DC charging piles remains around 6:4, and the proportion of AC piles is more, mainly because in the early stage of the industry development, slow charging AC piles are very suitable for manufacturers to seize the market, relying on the characteristics of simple structure, mature technology and low cost, However, after the technology and market of charging piles become mature, DC piles are the inevitable choice for future public charging piles. The average charging time of the DC charging pile is 1 hour and 54 minutes. 85% of the users can finish charging within 2.5 hours, while the average charging time of the AC charging pile is 5 hours and 45 minutes. 66.2% of the users need more than 5 hours of lengthy charging time. The difference between the two nearly 4 hours of time directly determines the obvious use preference of the car owner Z.
