EV Charging Terminology

Configurable current allows the maximum charging current to be set or limited during installation or configuration. It is normally assessed against site capacity, maximum demand, charger grouping and the behaviour expected when electrical demand changes.

A controller is hardware or software that manages charger operation, load control, communication or site-level coordination. In modern controller-worker terminology it can also replace the older term “master” in master-slave configurations, referring to the coordinating device or system that directs one or more worker/client devices.
