At 14:30 on August 8th, there was no trace of sunshade at the special vehicle charging station in Hanyang North Parking Lotor in Wuhan. The charging pile is carried out for compulsory verification. They couldn't care about sweating, and meticulously checked the accuracy of the accuracy of each charging pile.

The staff of the Wuhan Metrology Institute "physical examination" for charging piles at high temperatures

According to reports, since mid -July high temperature weather, the Wuhan Measurement Institute has visited the city's 50 stations, enterprises, and community new energy vehicle charging piles.

Before a charging pile, the examiner charged with a charging gun for 5 minutes at the standard device. The power of the mobile phone payment displayed was 2.065kWh, and the standard for the standard device displayed was 2.0472 kWh. Zhao Hui, an inspectionr, said: "According to the provisions of the charging pile verification regulations, the range of error scope of the charging volume cannot be greater than 2%. After calculation, the error of this charging pile is 0.86%, which is less than 2%.

At this time, the temperature during the charging pile is 41 ° C during the charging detection of the vehicle operation, and the environment in the vehicle load has reached 71 ° C. After continuously tested several charging piles before, the standard device will automatically stop working due to high temperature. After the standards such as shutting down, the standard device will be re -started to check. In order to improve the detection capacity, Wuhan's measurement of the strong inspection of the measurement of the measurement of the strong inspection is still raised, and the special inspection vehicle for the purchase of charging piles has been increased. After the car is insulated, the heat dissipation is better, and it can still be carried out at high temperature. In accordance with the requirements of the previous verification regulations, it takes about 20 minutes to detect a charging pile. With the release of the new regulations, the detection time will be shortened to less than 10 minutes.

It is reported that the charging pile of new energy vehicles is a category of compulsory verification. If consumers find obvious "problems" charging piles, they can complain to the market supervision department 12315.

According to the relevant person in charge of the Wuhan Market Supervision Bureau, there are more than 40,000 new energy vehicles charging piles in the city. Because the site is relatively scattered, in order to meet the charging of new energy vehicles and ensure fair trade, the personnel of the marketing institute still adhere to the front line at high temperature weather. They all insist on conducting testing so that the inspection should be inspected to ensure the accuracy of the charging pile meter measuring service.
