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.

Safety requirements (1) The substation shall be equipped with safety bulletin board, warning board, safety signal light and alarm bell. (2) The warning sign of "Stop, High Voltage Danger" shall be hung outside the door of the high-voltage distribution room and transformer room or on the safety column of the substation. The warning signs must face the outside of the fence. (3) There shall be obvious operation instructions on the high-voltage distribution device. The grounding point of the equipment shall have obvious signs. (4) There should be obvious signs of "safe passage" or "emergency exit" in the room. In addition, the layout design of substation and distribution equipment shall facilitate installation, operation, handling, maintenance, test and monitoring. High and low voltage distribution room, transformer room, capacitor room and control room should not have unrelated pipes and lines passing through. New energy vehicles should first focus on cities, but the busy IX region is often short of land, and the cost of land is high. In this regard, the government needs to give preferential policies to promote the construction of charging facilities. The development and operation of electric vehicle charging stations by electric power enterprises have inherent advantages.

Charging or changing? It is difficult to break through the pain points of the construction of power exchange stations: the construction speed of power exchange stations is amazing. From August 2019 to December 2020, the number of power exchange stations has increased from 245 to 734 in more than a year. The top three operators are respectively Aodong, Weilai and Botan, 286, 175 and 94. The electric vehicle power change mode refers to the centralized storage, charging and distribution of a large number of batteries through a centralized charging station, and the battery replacement service for electric vehicles in the battery distribution station or the integration of battery charging, logistics allocation and power change services. However, the pain point of the power exchange mode is still the bottleneck that is difficult to break through.

As a green means of transportation with broad development prospects, the popularization of electric vehicles will be extremely rapid in the future, and the future market prospect is also extremely huge. In the context of the global energy crisis and serious environmental crisis, the Chinese government actively promotes the application and development of new energy vehicles. As an important supporting infrastructure necessary for the development of electric vehicles, the charging/changing station has very important social and economic benefits. A campaign to build an electric vehicle charging/changing station has been launched nationwide. The overall system consists of four parts: electric vehicle charging pile, concentrator, battery management system (BMS), and charging management service platform.

Integrated overview: the fast charging pile (plug) equipment adopts the AC/DC integrated structure. It can realize both DC charging and AC charging. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. Appearance features: 1. Ergonomic design, taking full account of Chinese characteristics, after installation, the height of the whole machine, the height of the screen, the height of the keyboard, and the height of the charging connector slot are suitable for operation; 2. The form of upper outlet saves half of the operator's physical strength; 3. In consideration of people's usage habits and durability, touch and keyboard are mutually backed up. Touch screen and keyboard are designed to be rain proof and dust-proof; 4. Emergency stop switch with emergency stop; The charging connector placement slot is waterproof; 5m long flexible cable.

Charging every day: For many commuters, it may be enough to charge the car once every two or three days. However, some experts suggest that you should not try to save time and charge frequently every day, so that the battery can be in a shallow cycle state, which is more conducive to extending the service life. Pay attention to the phenomenon of poor contact between the plugs at both ends of the charging line: poor contact will lead to the heating of the plug, and once the heating time is too long, short circuit may occur, thus damaging the charger and battery. Therefore, the owner needs to check and replace the connector in time.
