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.

The function of the charging post is similar to that of the gas dispenser in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. Generally, the charging pile provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to print the corresponding charging method, charging time, cost data and other operations. The charging pile display screen can display the charging amount, cost, charging time and other data.

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

Model diversification: many people find that there are more new energy vehicles running on the street today, and the models are more abundant. Is that the case? By visiting the stores of the three automobile enterprises mentioned above one by one, the reporter found that the product power of new energy vehicles has been greatly improved, and can intuitively feel the strong development momentum of the industry. In Tesla's Beijing Huamao Store, two Model 3 cars are in the middle, and Model Y and Model X of SUV models are on both sides. The three models have the same style, dynamic and fashionable appearance, and simplified interior. The center console has no other physical buttons except for the center control display. From the appearance, the products of the three new energy vehicle brands all have a prominent feature, that is, the design style is fashionable, which is obviously ahead of fuel vehicles at the same price, close to or even beyond international luxury brands. Under the new consumption feature of "beauty is justice", this alone has greatly enhanced the attractiveness of products.
