Wuhan: The top temperature is a "physical examination" for charging piles

At 14:30 on August 8th, in the special car charging station of Hanyang North Parking Lot in Wuhan City, Hubei Province, there was no shade. Guo Wei, Lan Zhetao, Zhao Hui, and Deng Boyang are carrying out compulsory verification of 50 new energy vehicles charging piles. At high temperature, they carefully checked the accuracy of each charging pile.

According to reports, since mid -July, the Wuhan Measurement Institute has visited the "physical examination" of 50 new energy vehicle charging piles in Wuhan City, enterprises, and communities.

The reporter noticed that 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. The verification officer Zhao Hui said: "According to the provisions of the charging pile verification regulations, the charging amount of error 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 between the detection of the vehicle operation is 41 ° C, and the ambient temperature between the vehicle load has reached 71 ° C. In order to solve the problem of automatically stopping the work of the previous standard device and further improving the detection capacity, Wuhan's measurement has increased its investment, purchased a special detection vehicle for charging piles to ensure that the testing can still be carried out normally at high temperature. With the release of the new regulations, the time to detect a charging pile will be shortened to less than 10 minutes.

New energy vehicle charging piles are the category of compulsory inspection. At present, there are more than 40,000 new energy vehicles charging piles in Wuhan. Due to the scattered sites, in order to meet the charging needs of new energy vehicles, the test personnel of the measurement insist on conducting testing at high temperature weather every day to ensure that the charging piles should be measured to ensure that the charging pile measurement can be measured. The accuracy of the service.
