Background technique

With the development and popularization of new energy vehicles, more and more people will use electric vehicles in the future, and the charging problems of electric vehicles will become more prominent. There are two mainstream charging methods, one is Public charging piles or super charging piles that generally charge faster use high-current charging to shorten the charging time, but it takes 80-90 minutes to fully charge a car. The second method is to use the single-phase wall-mounted connection charger that comes with the car in your own garage. It takes about 10 hours to fully charge. If you subtract the current consumption during the peak period of home electricity consumption, it may take longer to fully charge. This method is also the main charging method in most areas without super charging piles.

On the other hand, there are often queues for refueling at existing fuel vehicle gas stations, and sometimes there is even a limited amount of refueling. It mainly appears in the central cities and first-tier cities of several major countries, and electric vehicles will also be developed first in these major cities. In the future, new energy electric vehicles may grow in a blowout manner. When enough electric vehicles appear on the market, each vehicle may be charged at any time. According to statistics, the average refueling time of a fuel vehicle is 2-3 minutes per vehicle. If it is replaced by an electric vehicle, it will take at least one hour to charge more than half of the electricity. At that time, not only the electric vehicle will not be able to charge smoothly, but the traffic will also be paralyzed. Even cities can't function properly.

When people are unable to charge at the charging station, they will naturally choose to go home to charge, and the main groups of people will concentrate on electricity between 18:00 and 22:00 after get off work. When tens of thousands of electric vehicles are charged intensively, the transformers in the area will be overloaded. That time period is also the peak period for residents to use electricity at home. Even if the transformer is not overloaded, it will affect the charging speed of electric vehicles.
