Flexible Charging with Single-Gun Full Power and Dual-Gun Sharing
The G45 mobile DC fast charger supports two practical charging modes for different operating needs. In single-gun mode, the available rated power is delivered through one charging connector to support faster charging for a single compatible EV.
In dual-gun mode, the charger supports equal power sharing between two connected vehicles. This mode helps commercial operators serve more than one vehicle when maximizing equipment utilization is more important than delivering full power to a single vehicle.
For example, an 80kW configuration can provide up to 80kW to one vehicle in single-gun operation, or distribute available power equally between two vehicles in dual-gun operation. Actual delivered charging power depends on the selected G45 configuration, vehicle battery voltage, battery management system communication and real-time vehicle charging demand.
