The control circuit of the electric vehicle charging pile (plug) is mainly completed by the embedded ARM processor. Users can swipe their cards to carry out user authentication, balance query, billing query and other functions, and can also provide voice output interface to achieve voice interaction. The user can select four charging modes according to the indication of the LCD screen: charging on time, charging according to the quantity of electricity, automatic charging, charging according to the mileage, etc. The electric vehicle charger controller and concentrator use CAN bus for data interaction, and the concentrator and server platform use wired Internet or wireless GPRS network for data interaction. For security reasons, the electricity billing and amount data are encrypted securely.

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.

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.

As the energy supply device of electric vehicle, the charging performance of electric vehicle charging post is related to the service life and charging time of the battery pack. This is also one of the aspects that consumers are most concerned about before buying electric vehicles. It is the basic principle for the design of electric vehicle charger to realize fast, efficient, safe and reasonable power supply for the power battery. In addition, the applicability of the charger to various power batteries should also be considered. The control system of the fast charger consists of: the control system of the fast charger adopts an intelligent variable pulse charging mode, that is, charging current pulse, including charging pulse T1, intermittent pulse T2 and discharge pulse T3.

Small electric vehicles are different from traditional gasoline vehicles. What should we pay attention to during maintenance? For electric vehicles, the battery acts as its "heart", controlling the forward power of the vehicle. Especially in the charging process, we need to pay special attention! Common sense of electric vehicle charging: batteries should not be overcharged or discharged too much: overcharge and discharge of batteries will reduce their service life. Overcharging will cause the battery to heat up, which may cause spontaneous combustion, explosion and other hazards in serious cases. While driving, if the electricity meter indicates the red light area, the driver needs to stop running and charge as soon as possible, otherwise the battery loss rate will greatly increase in the long run. It is understood that the average charging time of the general battery is about 10 hours. The charging time should be well controlled. If the battery temperature exceeds 65 degrees, the charging should be stopped.

According to the new national standard, the charging plug standard of different models in the future is the same. Xu Xinchao said, "Although there will be differences in voltage and power, theoretically it can be used in the same charging point. In addition, the new national standard attaches particular importance to the safety of the charging pile, which has always been the top priority. The standardized charging pile of new energy vehicles will automatically cut off power after charging, making breakthroughs in insulation and avoiding electric shock in rainy days, so as to avoid unnecessary dangers for new energy owners during charging.
