Information
Definition
Maximum charging rate is the highest charging power a charger can deliver under its rated conditions, usually expressed in kW. It is normally assessed alongside phase availability, circuit capacity, protective devices, cable sizing and DNO/site constraints.
Why it matters
It helps compare charging speed, but the actual rate also depends on supply capacity, vehicle limits, load management and shared power. For UK users, it affects installation cost, available charging power, protective device selection and how easily a site can be expanded.
