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.

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.

At present, solar cells are divided into several types according to the raw materials, structures and manufacturing methods used. Among them, crystalline silicon solar cells mostly refer to monocrystalline silicon solar cells and polycrystalline silicon solar cells using silicon semiconductor substrates as raw materials; In addition, there are amorphous silicon solar cells, which are made by evaporating amorphous silicon on glass substrates rather than silicon substrates based on the same film preparation method as liquid crystal panels. Monocrystalline silicon solar cells form solar cells on monocrystalline silicon substrates, and there are also products with conversion efficiency up to about 20%, which have excellent performance and reliability. However, the price of silicon substrate as raw material is expensive, and the power generation cost per watt is high. Although the conversion efficiency of polycrystalline silicon solar cells is lower than that of monocrystalline silicon solar cells, they have the advantage of relatively low cost.

Why does the new energy vehicle suddenly "break the circle" and make many consumers "turn into fans"? Compared with traditional fuel vehicles, what are the unique attractions of new energy vehicles for consumers? What are the characteristics and differences in products, marketing and services of different automobile enterprises? With these hot topics in mind, the reporter recently selected three enterprises in the high-end field of new energy vehicles, namely Tesla, Weilai and BYD New Energy stores in Beijing for experiential interviews to observe the changes of new energy vehicles in product power, price, marketing and service from the perspective of consumers. I hope to read with readers the reasons behind the unexpected growth of the new energy vehicle industry in the middle and high-end field, which is the "race track" of new energy vehicles.

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.
