Transformer substation for electric vehicle chargers: rating, outgoing feeders, metering and expansion

A transformer substation for EV chargers is sized from the charger list, the simultaneity factor and the power factor, plus site loads and a reserve for expansion. A hub with 4 x 150 kW DC and 6 x 22 kW AC chargers needs about 620 kVA, so 800 kVA is a sensible choice. The guide also covers LV feeders, MV or LV metering and preparing the substation for growth.
