What does a load calculation involve in EV charging projects?

Load calculation in EV charging projects is about estimating how much electrical load the site will actually draw at peak operation so you can size the electrical system correctly. You forecast how many chargers will be in use at the same time and at what power level, then use that to determine the required service size, feeders, and panel ratings, and plan for capacity now and for future growth. This involves considering different charging profiles (such as Level 2 versus DC fast charging), applying diversity factors so you don’t assume every charger hits peak power simultaneously, and checking potential utility constraints. The goal is to design an electrical system that can support the expected demand without overbuilding or underperforming. It’s not about the total equipment cost, appearance, or which EV models will be charged.
