State grid is the one of world's largest public utility enterprise and the largest power grid enterprise in China. It is also one of the most important enterprises in the construction and operation of public EV chargers for electric vehicles in China.At present, about 90,000 public chargers are operated by the state grid in various provinces and expressways, with DC fast chargers as the main and serving as the EV service company of the state grid.By 2020, the state grid corporation of China will have built 120,000 EV chargers, and the inter-city fast charging network will cover 202 cities in the Beijing-Tianjin-Hebei-Shandong and Yangtze river delta regions and in other regions.Since 2018, the state grid has implemented strict product and technical standards for key components such as shunt devices and electricity meters inside fast chargers to ensure accuracy and reliability.
Shanghai hanglong industrial co., LTD focuses on the research and production of shunts
、electrical connections and other electrical components.HL series shunts
are widely used in XuJi all series DC chargers, State grid intelligence DC chargers, HL shunt can adapt to a wider range of temperature, smaller temperature coefficient, more reliable operation, more accuracy, and longer life, effectively helping State Grid chargers to more reliable measurement of electric energy, and establishing the reputation of state grid charging operation.
