What is Dynamic Load Management in EV charging?

Installing a couple of charging points doesn't typically have a huge impact on the electricity infrastructure of a building. However, larger installations often require a little bit of smart charging magic. This is where load management comes in.

Consider providing charging for 20 electric cars in the garage of a residential or commercial building with 22 kW plugs (3 x 32 A, charging speed 100 km/h). This would require the building to get a 3 x 640 A electricity connection - costing you tens of thousands of euros.

But is it even necessary to charge all of the EV's full speed at the same time? Dynamic Load Management, DLM, ensures that charging can be done at full speed if there's enough capacity, and that charging loads are distributed between cars when there's more demand.

Controlling charging loads from the cloud

Dynamic load managementVirta's Dynamic Load Management solution is relatively straightforward, and requires no extra investments:

 

  1. Create groups of your charging points in Virta's Management System.
  2. Set a maximum total charging load for the selected group of charging stations.
  3. Now the system controls the charging power of each individual charging point automatically based on the maximum load you have set for the group.

 

Protect your local grid and cut your charging costs

Utilizing DLM from the cloud brings the charging infrastructure owner several benefits :

 

  • Restricting the total charging load protects the local grid - eliminate a risk of overloading even when multiple chargers are being used simultaneously
  • Sharing the charging load cuts costs for the required electricity connection
  • No physical wiring between the devices - no extra infrastructure or installation costs

Virta's DLM solution works with almost any smart charging devices. Devices need to be connected to Virta's platform through a GPRS connection using the Open Charge Point Protocol (OCPP).

 

This overview is just a simplified version of the solution: we're constantly working towards bringing new ways to distribute loads between charging cars.
