Compared with supercharging stations in urban areas, charging piles in high-speed service areas are as expensive as supermarket products in service areas. A few days ago, an electric car owner complained in a post that high-speed charging was so expensive that he couldn't even charge his car for 100 yuan. The charging page posted by the car owner shows,It is currently 84% charged, with 40.13 kWh of electricity charged. The charging fee is 72.23 yuan, and the charging rate is 1.8 yuan/kWh.

For comparison, the charging fee at urban supercharging stations is generally about 1 yuan/kWh. If it is night time, the charging fee at valley power can be reduced to 0.5 yuan/kWh.
The car owner’s complaints also aroused heated discussions among netizens. One netizen replied:"When I refuel, it's 2 or 300 at a time, and I don't see you saying it's expensive."The car owner himself also laughed at this statement, and when he thought about it carefully, it was indeed the case.

Some netizens have calculated the cost of running a tram on the highway. "With 40 kilowatt-hours of electricity, taking the middle value, it can run about 250 kilometers on the highway. The charging fee is 72 yuan, which is equivalent to a formal cost of 0.28 yuan per kilometer. It is still half the cost of a gasoline vehicle."
In fact, charging charges at charging piles in high-speed service areas are generally much more expensive than in urban areas. If you are not in a hurry, you can drive off the highway intersection and charge in the city. In addition to being cheaper, you don't have to queue up for charging stations.
