How Is EV Charging Infrastructure Built for Rental Fleets?

The load study is the foundation document. I inventory the fleet electrification plan, assign charger power levels by stall type, and model the charging profiles across the operating day — arrivals, dwell times, departures. The managed peak — what the load-management system will actually allow — sizes the service, the switchgear, and the feeders. I then take that number to the utility early, because a service upgrade or a new transformer has the longest lead time in the project. The one-line diagram shows the full build with the phasing plan, so the utility, the reviewer, and the contractor all see the same project.

Fleet chargers get handled hundreds of times a year, so the physical design is about durability. Pedestals sit on protected islands or walls clear of the vehicle swept path; cables hang on management systems — retractors or holsters — that keep connectors off the pavement; and the parking stalls are striped and signed for EV charging so a gas car never blocks a charger. Lighting at the charging stalls supports nighttime plug-in and camera coverage. The equipment is specified for the outdoor environment with the right enclosure ratings, and every charger location has a clear service access path for maintenance.

A rental fleet EV charging design is ready when it clears this checklist. The fleet's mornings depend on it. • Load study modeling fleet patterns; service sized for the managed peak, not nameplate sum • Charger power matched to stall dwell time: Level 2 for overnight, DC fast for quick turns • Load-management system specified with the hardware, prioritizing earliest rentals • Conduit, duct banks, and switchgear installed for the ultimate charger count on day one • Utility coordination started early; metering separating fleet charging energy
