This year's Spring Festival, God really has its own arrangements, rain and snow before the holiday, rain and snow after the holiday, and the weather is sunny in the New Year's Day, so that everyone can rest assured. However, friends who want to go home are like a catastrophe during the New Year, and it is difficult to return to their hometown, and it is difficult to go back to work after the Spring Festival.
In recent years, the Spring Festival, high-speed is busy, and now it is the norm for people to buy cars, but gasoline has soared, and many people say that cars can afford to drive, so more and more people choose to use electric vehicles, after all, electricity is still much cheaper. However, the biggest problem with electric vehicles is that it takes a long time to charge without electricity, and this time is really unaffordable. If you encounter low temperatures, electric vehicles have many disadvantages, the power will be consumed faster than usual, dare not turn on the heating, and are more afraid of gambling on the car.
I can't help but think of a way, if someone can make a battery that can be replaced by ordinary people casually, will this solve the problem of insufficient power of electric vehicles, and also solve the trouble of charging electric vehicles on the road, and also save the money of charging on the road.
I really hope that the scientific and technological personnel can solve this problem as soon as possible, so that everyone can travel with confidence.
