Recently, a citizen in Guangzhou reported that the electric bicycle charging piles in the community are ridiculously expensive. The screenshot of an order for a certain brand of charging pile provided by him shows:A single charge charges 2.08 kilowatt hours, the electricity bill is 2.04 yuan, and the service fee is as high as 6.9 yuan.Based on this calculation, it costs about 9 yuan to charge an electric bicycle once.

The published charging standard after scanning the code shows that the unit price of electricity for the whole period is 0.64 yuan/kWh.
The service fee is calculated according to the power range: 0-100W 0.4 yuan per hour; 100-200W 0.5 yuan per hour; 200-300W 0.7 yuan per hour; 1000-1500W service fee reaches 1.6 yuan per hour.
The power of this citizen's electric vehicle is in the 200-300W range, and the service fee is only at the intermediate stage.
The citizen said that he originally thought that the charging cost was mainly the electricity fee, but he did not expect to find out after charging that the service fee was the bulk of the charge. Charging an electric bicycle would be a big expense in the long run.
