Load management
Every building and every site has a limited amount of electricity, so it's important to be strategic about how to use that power optimally. Load management is a smart energy distribution tool that does this job for you.
With the rapid increase in electric vehicles across Europe, the strain on the electricity grid will continue to increase, and with it the demands on the performance of your electrical installations. It is important to balance the available power at all endpoints that require power (e.g. between your charging stations and your building) so that everything can continue to run without interruption.
An unbalanced system can lead to reduced efficiency because electricity is not distributed evenly or optimally, so the risk of circuit breakers tripping is very high. This can lead to failures and damage to your charging stations and electrical equipment over time, significantly reducing their lifespan.
Static load management
Static load management is a setup where the site has a ‘fixed’ (static) load on each charge point. A large number of housing associations and apartment complexes with multiple charge points use static load balancing to distribute the load evenly.
Let's say there is a location with a total of 30 amps and 3 charging points; each charging point receives 10 amps, regardless of whether an electric vehicle is being charged or not. Similar to a fixed price menu. No matter what happens, everything is distributed evenly.
Dynamic Load Management 2.0
With dynamic load management, the power to be distributed to the charging stations is distributed by a mini server and an external meter, a so-called smart meter. The individual components are connected via the MODBUS integration. Thanks to the information from the smart meter, the server always knows how much power the building currently needs and can thus optimally supply the charging stations with the energy that is still available. PV systems and battery storage can also be integrated via the Modbus integration.
Here's an example: if a building has 40 amps available, but 10 amps are used primarily by the building itself (for example for an elevator or other essential services), the meter reports this to our system and the charging points share the remaining amount between themselves. In this example, the charging points share 30 amps, and these 30 amps are "dynamic", meaning that if two cars are charging, they each receive 15 amps, but if there is only one car, that car would receive the full 30 amps.
