EV Charging Load Balancing

At Elmtronics, our electric vehicle charging stations allow load balancing for convenience, cost-efficiency and practicality.

What is EV Charging Load Balancing?

Electric car charging load balancing refers to power distribution across multiple vehicles. For instance, an EV charging station with a high capacity will distribute available power to all vehicles currently charging. This means that multiple vehicles can be charged from the same EV charging station.

EV Charging Load Balancing Situations

There are a variety of situations where EV charging load balancing can come into play. For example:

In case of one vehicle

When one vehicle is connected, it will change with the full available capacity that the charging station can deliver. Electric car charging load balancing is not active in this situation.

In case of two vehicles

When two cars are connected that demand in more capacity than the electrical installation can deliver, the charging station will activate EV charging load balancing. This way, the connection is protected against overload while the cars can still be charged. In this situation, the capacity will be divided over the two vehicles equally.

In case of one vehicle with a higher capacity and one with a regular capacity

When two vehicles are connected and one vehicle requires less charging capacity than the other, the charging station will divide the availability energy to charge both vehicles. The charging station will supply the high capacity vehicle with power first and will supply the rest of the available energy to the other vehicle.

In case of two vehicles with high capacity

When both vehicles with high capacity demand more than half of the available power, the charging station will activate ‘Time Sharing’. This means that the vehicles will alternate charging at full power every 15 minutes.

High Charging Capacity with Low Connection Costs

With the increasing range of electric vehicles, charging capacities are increasing as well. Without smart solutions, expensive investments must be made to upgrade the electrical installation. EV charging load balancing offers a solution for powerful charging with a cost efficient connection.


Electric car charging load balancing is ultimately suited for, among others, office buildings, where more than one electric vehicle is being charged and where it is not feasible to increase the capacity of the electrical installation.

Suited Chargers



With an Alfen electric vehicle charging station, you can save money on connection costs. The smart electronics in the charging station are suited for EV charging load balancing. This means that the charger monitors the maximum charging capacity and divides the available energy over the connected vehicles, allowing for flexible division of the charging capacity.
