Development background of charging pile industryLow-carbon economy has become the main theme of China's economic development. As an important part of new energy strategy and energy Internet, electric vehicles will surely become the focus of the integrated development of China's automobile industry and energy industry. With the rapid expansion of the popularization and application scale of electric vehicles, the demand and construction of supporting electric vehicle charging infrastructur

With the rapid development of electric vehicles, the contradiction between the difficult charging and maintenance and the increasing charging facilities and the small number of existing operation and maintenance personnel, low skill level and lack of relevant experience has been exposed.Charging pile without operation and maintenance is just like a ship without rudder or an aircraft without pilots, which seriously hinders the development of new energy industry and even brings traffic safety risk
