AutoBeta(AutoBeta.net)08/19 Report--

Recently, due to the influence of high temperature weather, the load of several provincial power grids across the country has reached an all-time high. In order to ensure the safe operation of the peak power grid, State Grid has piloted electric vehicles to avoid peak charging in Chongqing, Zhejiang and Hubei provinces with high temperature and high load. The pilot covers nearly 350000 charging piles. During the peak electricity consumption period, from 3 p.m. to 10:00, the charging power will be adjusted appropriately to stabilize the peak load.

In addition, State Grid will also issue 50% discount coupons on charging service fees through mobile phone charging clients to guide electric car owners to recharge at night and other troughs. According to qu Xianjun, deputy general manager of State Grid Smart vehicle networking Technology Co., Ltd., the number of electric vehicles in the three provinces and cities involved in off-peak charging this time is nearly 800000. If they are charged during peak hours, it will increase the load of the power grid by 2 million kilowatts, which is equivalent to the electricity load of more than 300,000 households. If the measures of load regulation and off-peak power consumption are taken, it will ensure the security of the power grid and better protect the electricity demand of the people's livelihood.

It is worth noting that the tight supply and demand of electricity caused by the hot weather has not only brought inconvenience to electric car users to charge, but also forced a number of car manufacturers to stop production. On August 14, the Sichuan Provincial Economic and Information Bureau and the Sichuan Electric Power Company of the State Grid issued an emergency notice on expanding the scope of industrial enterprises to transfer electricity to the people. Factories set up by Toyota Motor, FAW-Volkswagen, Shenlong Automobile and Geely Commercial vehicles in Sichuan have all been affected by this round of power cuts. On August 18, Changan Automobile announced that in order to fully protect people's livelihood, Changan Deep Blue and its major suppliers suspended the production of SL03 vehicles and spare parts on August 15. It is expected that this round of shutdown will last until the 24th, which will have a certain impact on the total production and delivery scale of SL03 this month.

Of course, in addition to car companies, new energy vehicle charging piles have also been affected. According to official information released by Tesla, only two of the 14 overcharging stations in Chengdu remained open as of Aug. 17, while the rest were in a state of limited service or temporary closure. Xiaopeng issued a notice on the power-limited operation of Chengdu-Chongqing charging stations, five of the small overcharging stations in Chengdu and Chongqing are temporarily closed, and the others are partially open. Some netizens said that they had recently received a text message from Xiaopeng. According to the text message, several of Xiaopeng's overcharging stations in Chengdu have recently adopted irregular business or suspended business to ensure residents' electricity consumption due to the extremely high temperature.

In addition, a number of special call public fast charging stations have also been unable to recharge, station staff said, "in response to the Sichuan power restriction policy, the power supply of the special call stations in Sichuan has been suspended from 00:00 on August 15 to 24:00 on August 20, 2022. After the power restriction order contact, the field station will return to normal. Due to the impact of power cuts, a new energy car owner also posted a post saying that he was not charging, but on the way to find a charging pile.

In response to the pilot implementation of electric vehicle peak avoidance charging, some professionals said: "in the summer peak power consumption, it is necessary to take appropriate peak avoidance measures." In addition, Lin Boqiang, director of the China Energy Policy Research Institute of Xiamen University, also said that China's industrial electricity consumption accounts for nearly 70%. As long as industry uses less, it will have no impact on the lives of residents. The high temperature is only for a period of time, and the impact is controllable.
