After the completion of charging piles in some places, operation and maintenance become a problem. On the one hand, the number of urban public charging facilities is small, and the distribution is uneven and unreasonable; On the other hand, the management service platforms of the charging infrastructure construction and operation units have not yet achieved interconnection, nor has there been a unified, open and convenient payment platform, which has caused great inconvenience to charging infrastructure users. In addition, in the development process of new energy vehicle industry, there is a widespread problem of focusing on vehicles rather than charging infrastructure. In addition, the national early support policy is mainly aimed at new energy vehicles and does not cover charging facilities. Except for a few cities, most cities have no local subsidies. "This leads to the coexistence of vehicles without piles and piles without vehicles." Moreover, charging infrastructure construction involves urban planning, construction land, distribution network construction and transformation, property management and other aspects, and it is necessary to coordinate multiple competent departments and relevant units in the implementation process.

On board charging device refers to the device installed on the electric vehicle that uses the ground AC power grid and the on-board power supply to charge the battery pack, including the on-board charger (Figure 1-13), the on-board charging generator set and the operating energy recovery charging device. A AC power cable with a plug is directly inserted into the charging socket of the electric vehicle to charge the battery. On board charging devices usually use contact chargers with simple structure and convenient control, or inductive chargers. It is designed completely according to the type of on-board battery, with strong pertinence. Off board charging device, i.e. ground charging device, mainly includes special charger, special charging station, general charger, charging station for public places (Figure 1-14), etc. It can meet various charging modes of various batteries. Generally, the off board charger has large power, volume and weight to adapt to various charging modes.

Over the past few years, China's new power vehicles have entered a new stage of development. Compared with the previous two years, its functions have entered a new stage. The environmental trend of new power vehicles has become more mature. Since the launch of new power vehicles, the national policy has been continuously supported, and friends have gradually taken over the new power vehicles, But do friends inquire about new power cars? The following editor will explain to friends what the policy of charging pile for new power vehicles is! Description of new power vehicle charging pile policy - brief introduction The threshold of awards for the city of atmospheric pollution in 2016-2020 The number of new power vehicles promoted is divided into no less than 30000, 35000, 43000, 55000, 70000, and the number of new power vehicles promoted accounts for no less than 3%, 4%, 5%, 8%, and 10% of the total number of new and updated vehicles in the inland area.
