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.

Standard Load Balancing (SLB)

Divides available power between vehicles.

Standard Load Balancing example with 1 car

» One vehicle is charging – the maximum amount of power is available

Standard Load Balancing example with two cars

» Two vehicles are charging

» Charge is divided equally between EV’s at a lower power


» Cars are charged at full power, alternating every 15mins

Active Load Balancing (ALB)

Prioritises and regulates transfer of power from the building to the chargers.

Active Load Balancing example

» Max amount of power allocated to charging stations is set

» Electric vehicles are connected for charging

» Available power capacity is evenly distributed between the users

» When an EV is fully charged, other connected vehicles will be supplied with more power

» Power transfer from the building to the charger is regulated

Why load balancing?

EV charging load balancing offers a solution for powerful charging with a cost-efficient connection. Without load balancing, expensive investments in upgrading existing electric installation.

Who is load balancing best suited for?

Load balancing is ultimately suited for:

» Office Buildings

» Retail Parks

» Commercial Buildings

Or anywhere else where multiple EVs are being charged and where it is not feasible to increase the capacity of the electrical installation.
