Phase balancing

Phase balancing distributes electrical load across the phases of a three-phase supply so one phase is not overloaded while spare capacity remains on the others. It is especially relevant where several single-phase EV chargers share a three-phase site supply. A site can be within its overall power limit and still have a problem on one phase. The current in each phase therefore needs to be considered when allocating charging power, rather than treating total site kW as the only constraint. Phase balancing can be designed statically by spreading chargers across phases, or managed dynamically where compatible hardware and control architecture allow charging demand to be adjusted.
