Why is isolation and protection important for Ev Charging Station?

2025,08,15

With the growth of new energy vehicles, Ev Charging Station are increasingly being put into use. With the promulgation of the new national standard, which covers charging standards, interface standards, and communication protocols, there is now a unified standard for charging interfaces and communication protocols for new energy vehicles in China.

New Energy Multifunctional Charging Station Smart Complex

To ensure the safety and compatibility of new energy vehicle charging, safety measures have been added, including safety isolation and protection for Ev charging station, temperature control for charging, linkage between mechanical and electronic locks, and overload and short-circuit protection. Furthermore, charging control guidance and timing, fault classification information, and redundant protection have been further refined, enhancing the adaptability and operability of the standard.

Ev Charging Station are often located outdoors and powered by the grid, inevitably encountering abnormal voltage conditions such as lightning strikes and surges. If the control circuits within an Smart Integrated Charging Pile are not isolated, internal circuit failure can occur, leading to dangerous accidents such as short circuits in the vehicle or electrocution.

The internal architecture of an Smart Integrated Charging Pile primarily consists of the control and management unit, which primarily includes the main control unit, voltage control unit, current control unit, display control unit, battery control unit, and printer control unit. Therefore, the safety standard of Ev Charging Station firstly needs to protect the internal card reader, touch screen, electricity meter, and billing control unit from lightning surges. Therefore, it is also necessary to carry out relevant isolation protection at the connection end of the billing control unit, card reader, and electricity meter.
