At the 14th Beijing Expo, various new energy vehicles and electric vehicle charging and changing equipment attracted attention. It is understood that the first batch of 78 newly-developed electric sanitation vehicles will be the first to be put into use in the Haidian and Chaoyang districts.
4 minutes to complete the battery replacement
In Hall 2 of the National Exhibition, the State Grid Beijing Electric Power Company demonstrated the process of replacing the battery of a small sanitation vehicle at the exhibition site. After power is turned on, the robot removes the battery from the 2-ton sanitation truck and installs the battery on the battery rack to the vehicle.
The entire battery replacement process is fully automated and takes only 4 minutes to complete. The mobile charging station can charge 4 to 8 electric vehicles at the same time. The on-site staff stated that Beijing Electric Power Company has built 7 electric vehicle charging and switching stations, including the space bridge, Beitucheng, Majialou, Yanqing, Datun, and Hujialou, and plans to build 4 new electric vehicle replacement stations in Xicheng and Dongcheng. , Providing electric power services for the purely electric classified garbage trucks newly put into operation in the urban area, and two tentatively set up at Drum Tower and Baiyun Temple. 
Thousands of electric sanitation trucks will be invested
The latest electric sanitation cars also appeared on the site of the Zibo Zhongguancun Independent Innovation Achievements Exhibition. From dozens of micrometer dust to ordinary pebbles and leaves can be effectively removed. The dust removal rate is over 98%, and it is better to breathe it over ten times. According to the research and development personnel, compared with ordinary sanitation vehicles, electric sanitation vehicles have zero emissions, low noise, and can be exchanged for electricity. They can run for three hours or more than 100 kilometers in one run.
According to the personnel in the Zhongguancun exhibition area, in June 2011, the first batch of 78 newly-developed electric sanitation vehicles will appear on the streets of Beijing and take the lead in the two districts of Haidian and Chaoyang. By the end of 2011, there will be close to 1,000 electric sanitation vehicles and 300 electric buses.
