What is the prospect of charging piles for electric bicycles in residential areas?

Should be able to make money, but also depends on the amount of installation. Our unit is called Che Chong 'an downstairs. There are 2 charging piles, and 20 parking spaces are full every day. It takes 1 yuan to charge for 3 hours. According to 40 yuan's calculation, I estimate that the profit can be around 20 yuan, while most rechargeable bicycles are only charged once, 1 day, 20654, 38+0 months, so it is estimated that it should be no problem to pay back in half a year. Installation. There is no maintenance in this later period, just lie down and count the money, mainly depending on the amount of shop.
