Load balancing means you can install multiple charging stations for electric vehicles with an unchanged connection capacity. In this process, the charging power is distributed equally across all electric vehicles to be charged. Load balancing means you can avoid cost-intensive, one-off increases in connection capacity and prevent peak loads that result in higher demand charges.

Our success stories
An industrial enterprise purchased 15 electric cars for its service employees, which are only used during the day. It wants to install 15 charging stations with 22 kW charging power.
If charging without load balancing, the enterprise would need to expand the grid connection by 180 kW. This would lead to infrastructure costs of approx. € 32,000 that the interconnecting utility will claim. The higher connection capacity means that the demand charges can also increase by up to € 15,000 per year.
The fact that the charging stations are constantly balanced to the building’s power requirement by our dynamic load balancing ensures that the additional charging processes do not cause the available connection capacity to be exceeded. We can therefore save you additional grid expansion and operating costs.
Fleet operation is not restricted by slower charging processes, as the electric vehicles only reach the company site in the afternoon and can be conveniently charged overnight.
A bus operator wants to replace 24 of his buses with electric buses and to build the necessary charging infrastructure. These e-buses charge with up to 150 kW of power. The grid connection needs to be expanded, the size can be reduced with prioritised load balancing, and the design can therefore be made more cost-efficient.
In doing so, the grid expansion can be reduced from 2.3 MW to 500 kW, and the related costs reduced by €320,000. The operator also saves around €140,000 per year with regard to demand charge costs.
Prioritised load balancing charges electric buses depending on their schedules, and ensures that they are fully charged at the next scheduled departure time. The charging processes of the various vehicles are spread over the entire day and not carried out at peak times.
This allows low power to be drawn from the grid throughout the day, rather than creating peak loads. In turn, this creates cost savings in grid expansion and demand charges.
