Without load balancing, only a handful of charging points fit on a standard connection. Smart distribution makes room for many more.
Three forms
Static - each charging point gets a fixed maximum power allocation. Simple, but inefficient: unused capacity from an inactive point is lost and not available to others.
Dynamic local - charging points communicate directly with each other via the local infrastructure. Unused capacity is automatically made available to an active point. In practice, this is often faster and therefore smarter than cloud-based control. Zaptec works this way using a patented 3-phase balancing method.
Dynamic via cloud - central management software controls all charging points based on live consumption data, prices and green energy mix. Can also take into account the total building consumption.
How it works in practice
When you plug in, you receive an email with the current electricity price, the green mix and a suggestion for the best charging time. The system automatically adjusts your session if more or less capacity becomes available on the connection.
