V2G DC Charge Station

Pain Points in the Application Scenario

The AC side is powered by 220V/380V AC, with an externally mounted residual current protection device that requires Type A protection to ensure personal safety. This device also needs reverse-wiring residual current protection. The V2G DC bidirectional charging system requires DC contactors to meet an electrical life of 1000 cycles at a maximum DC1000V and be non-polarized. The contactors are prone to contact burnout.

Value of the Solution

The RCBO product support line from both top and bottom, with Type A protection to solve the problem of ‌harmonic interference misoperation‌. DC contactor has the non-polarized function, match the DC1000V electrical life of 1000 cycles‌ requirement and the contact has strong ‌anti-burning capability to keep the station operation safety.
