Most AC EV charger “ground fault” errors are misunderstood. An EV charger does not verify whether a PE (protective earth) wire is physically connected; it checks if the ground is electrically valid via N-PE voltage detection. In 99% of 7kW residential/commercial AC chargers, normal operation require

Power distribution in a dual-gun DC charging station is achieved by a central controller, which manages power splitting between the two guns using DC contactors to dynamically allocate power based on demand, often enabling full-power single-gun charging or simultaneous, split-power dual-gun charging
