Is it illegal to charge 1 yuan 1 kwh for car charging piles in some residential areas of Jiangshan Town, Yinzhou District, Ningbo?

In fact, the charging standard of charging piles consists of two parts, the first part is the basic electricity fee, and the second part is the service fee, but it is hard to say exactly how much, because the standards vary from place to place. After all, the electricity tariff standards in each region are different. But in general, the basic electricity charge is limited to less than one yuan, and most areas should be around 0.8 yuan. If the service charge is added, the cost per kilowatt-hour should be less than two yuan.
