The 2.000€ case for dynamic load management

Learn what options there are when it comes to load management, how they differ and how you can benefit from dynamic load management.
There are three ways to deal with loads of charging infrastructure.
Unmanaged
The simplest option - no management. The charging infrastructure is always given the load it requests. This means all charging points can charge with full power at all times. Sounds great? Well, there's a catch. There is no overload protection so high loads can cause blackouts. Furthermore, the high peaks drive up your grid tariffs. So this option is only suited to operate a small number of charging stations.

Static load management
Apply a static cap on the load supplied to your charging infrastructure. Whilst this avoids extreme peaks it also has significant drawbacks. In periods of low base loads static load management limits the charging power even though no new load peak would be caused. Moreover, in periods of high base loads static load management does not protect against overloads.
Dynamic load management
The most advanced option. Dynamic load management considers the load on the grid connection point in real time and adjusts the load supplied to the charging stations accordingly. This has two significant advantages over the other options. First, there is a permanent overload protection and peak loads are limited. Second, the charging power is only limited in periods of high base loads. This ensures that EVs can always charge with the maximum load while no new peaks are caused so you can operate more charge points on your existing infrastructure, save on grid tariffs and don't worry about overloads.

Save money and avoid overloads with dynamic load management
Save upfront on grid extension costs
Without load management charging infrastructure can quickly double your previous peak load. Most likely this exceeds the capacity of your grid connection point. An extension of the grid connection is expensive. Depending on the exact circumstances the costs amount to more than 50,000€.

Save annually on grid tariffs
Your grid operator applies a charge to each kW of the highest peak load you recorded in a year. Usually, around 100€ per kW of peak load are billed. A normal charge point supplies 21 kW. This means without any load management a single charge point can cause around 2,000€ of grid tariffs per year.
