An EV charging specialist in Indianapolis plans fleet depot charging around shift changes because the time vehicles sit between shifts determines the charger type, the number of chargers, and the size of the monthly utility bill. Counting parking spots tells you where chargers could go. Shift schedules tell you what those chargers actually need to do.
Why Shift Schedules Come Before Site Plans
Most fleet managers start with a lot map. How many stalls, where the panel sits, how far the trench runs. That’s useful. But an EV charging specialist in Indianapolis usually asks a different question first: when does each vehicle leave, and when does it come back?
Two depots with the same 20 parking spots can need completely different setups. One runs a single day shift. The other runs vans around the clock with short breaks between routes. An EV charging specialist in Indianapolis designs for the schedule, because a charger that fits the lot but not the shift pattern leaves vehicles short at dispatch.
Dwell Time Decides the Charger Type
Here is why this matters so much. Level 2 chargers deliver roughly 7 to 19 kW and suit fleets with overnight dwell time of four hours or more. For a van that sits all night, that’s usually plenty.
Multi-shift fleets are a different story. In a 30-minute break, an 11 kW Level 2 session adds only about 5.5 kWh, roughly 20 to 25 miles of range for a delivery van. That may not cover the next route.
So a depot with tight turnarounds often mixes both. Level 2 handles the overnight fill. DC fast charging covers the short gaps between shifts.
Plug-In Timing Shapes the Utility Bill
This part catches many fleet owners off guard. Many commercial utility bills include a demand charge, which looks at your highest average power use in any 15-minute window during the month and bills a fee per kW, ranging from about $3 to $40.
Picture 15 vans rolling in at 5 p.m., each plugging in at once. That single spike can set the demand charge for the entire month. A single 150 kW DC fast charger at full output draws about as much as ten Level 2 chargers running together, which makes the timing even more sensitive.
A specialist usually looks at:
- Arrival waves. Which vehicles return first, and which can wait to start charging.
- Departure deadlines. Which vehicles must leave full, and which only need a partial charge.
- Staggered start times. Managed charging software can spread sessions across the night instead of stacking them.
- Rate periods. Some utilities offer time-of-use or special EV rates worth asking about.
Charger Counts Follow the Schedule Too
One charger per vehicle sounds simple. Sometimes it’s right. With overnight dwell and managed scheduling, though, a depot might share chargers across more than one vehicle per night. Other depots need extra chargers because every vehicle returns within the same hour.
It’s counterintuitive. More vehicles don’t always mean more chargers, and fewer vehicles don’t always mean fewer.
Frequently Asked Questions
How much does fleet depot charging cost to install?
Cost depends on charger type, the number of ports, and whether the site needs a utility service upgrade. DC fast chargers cost far more per port than Level 2.
How long does a depot charging project take with an EV charging specialist in Indianapolis?
A small Level 2 install can wrap up in weeks. Projects that need a utility service upgrade often take months.
What does the planning process usually include?
It starts with shift schedules, routes, and daily mileage, then moves to a site survey and load calculation. Utility coordination, permits, installation, and inspection follow.
Can existing parking stay in use during installation?
Often, yes, with work phased by section of the lot. Trenching near the service entrance may close some stalls for a few days.
Are managed charging tools necessary?
Not for every depot. They help most when many vehicles arrive and plug in at the same time.
Matching Chargers to How the Fleet Actually Runs
A depot’s charging setup works best when it follows the fleet’s real schedule. Dwell time points to Level 2 or DC fast charging, arrival patterns affect demand charges, and departure times set how much each vehicle needs before it leaves. Parking spots come into the picture after you answer those questions.
