Operation and maintenance of charging pile

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 risks. Strengthening the infrastructure construction of charging facilities is an important premise to promote the development of domestic electric vehicles.

NTC Noel testing can assist enterprises to regulate the operation, maintenance and management of electric vehicle charging stations and charging piles. To ensure the orderly and stable operation of its various production operations, promote the improvement of its management level, and solve its maintenance and maintenance difficult, long time and a series of problems. Adopt scientific methods to assist enterprises to strengthen operation and maintenance management.

Using the network technology and mobile Internet technology, recharge electric car users with safe and convenient services, manufacturers for charging pile, charging infrastructure operators to provide convenient and reliable operation management, for different types of charging charging pile owners to build ecological Shared service operation platform, realize the "Internet + charging infrastructure" service, effective support wisdom urban infrastructure construction.

Common problems of charging pile operation and maintenance:

1) Power off: The charging pile is disconnected from the power supply system, and the power cannot be obtained.

2) Output failure: Failure to output the correct voltage to the electric vehicle will cause charging obstruction or overload, which will easily cause faults to the electric vehicle.

3) Too high temperature: too high ambient temperature will lead to reduced service life of internal components of the charging pile, which will not give full play to their performance.

4) Too high humidity: Too high humidity environment is easy to lead to internal oxidation phenomenon, resulting in equipment failure.

5) Working status: It is necessary to go to the site to check whether the charging piles are in charging or standby state. There are a large number of charging piles, so it is difficult to quickly understand the running status.

6) Billing setting: Every time the charging fee changes, we have to set it on site for each charging pile, which wastes a lot of time and labor cost.
