1 optimization problems
This page is for an SMB fleet operator running 10-100 electric vehicles (courier, delivery, taxi, rental, municipal service) — the question is when and at what power level to charge each vehicle when it returns to the depot. Wrong sequencing triggers three problems at once: every vehicle plugs in at 6 pm and the transformer spikes past the contracted peak (the utility charges a penalty), vehicles fill up on the daytime tariff and miss the cheap night rate, and constant fast charging burns the batteries out in a few years. If those three costs are not managed together, the cheap electricity savings get eaten by the battery OPEX. Manual sequencing becomes mentally exhausting past 30 vehicles.
