Last-Mile Delivery Fleet Charging: Infrastructure for 50 to 500 Electric Vans

# Last-Mile Delivery Fleet Charging: Infrastructure for 50 to 500 Electric Vans

Last-mile delivery is the easiest fleet segment to electrify and the hardest to get wrong. The routes are short, the vehicles return to base every night, and the TCO math already works. But the scale — 50 vans becomes 200, becomes 500 — requires infrastructure planning that most depots weren't built for.

DHL, UPS, and FedEx have committed to a combined 20,000 electric delivery vehicles by 2026. Amazon has ordered 100,000 Rivian EDVs. The last-mile EV transition is not a pilot anymore. [ALICE, 2026; Amazon, 2025].

The Physics of Delivery Van Charging

A last-mile delivery van drives 50-100 miles a day with 100+ stops. By the time it returns to the depot at 6 PM, the battery is often below 30%. It needs to be at 90%+ by 6 AM the next morning.

That's a 12-hour charging window. A van with an 80 kWh usable battery needs about 50-60 kWh overnight, which a 22 kW AC charger can deliver in roughly 2.5-3 hours. Even with 50 vans, staggered charging on 22 kW AC ports works.

But delivery operations are getting tighter. Two-shift operations, same-day delivery, and shorter turnaround windows are pushing the power requirement higher. A van that returns at 2 PM and needs to roll again at 5 PM has three hours, not twelve. That requires 30-60 kW DC.

Power Planning by Fleet Size

The key insight: a single-shift depot needs far less power per vehicle than a two-shift operation. Factor your shift schedule before you buy hardware.

Depot Layout for Delivery Vans

Last-mile depots are tight. Parking is at a premium, and every square foot counts. Best practices from operating depots:

Staggered charging. Don't plug in all 100 vans at 6 PM. The first wave plugs in at 6 PM and finishes by 10 PM. The second wave plugs in at 10 PM and finishes by 4 AM. This halves your demand peak.

Cable management. Overhead cable retractors keep cables off the ground and within reach of the charge port regardless of parking orientation. They cost $500-1,000 per port and prevent trip hazards, vehicle damage, and connector wear.

One-way traffic flow. Separate inbound and outbound lanes. The last thing you want is a new EV driver backing into a charger at the end of a 10-hour shift.

Future-proof conduit. Run empty conduit for double your current charger count during initial construction. Trenching later costs 3-5x more than running conduit now.

Dedicated maintenance bays. At least one bay should have a high-power DC fast charger (120+ kW) for diagnostic charging, software updates, and emergency rapid charging.

AC vs. DC: What Delivery Vans Actually Need

For single-shift operations with a 10+ hour overnight window, AC Level 2 at 7-22 kW is usually sufficient and dramatically cheaper. A 22 kW AC charger costs $2,000-5,000 installed vs. $25,000-50,000 for a 60 kW DC charger.

The decision tree: - Overnight only, 10+ hours: AC Level 2 (7-22 kW) - Overnight + mid-day top-up: Mix of AC and low-power DC (30-60 kW) - Two-shift, 2-3 hour turnaround: DC fast charging (60-120 kW) - Mixed fleet with larger step vans: DC (60-150 kW)

FBK POWER's Wall-Mounted AC Chargers and Pedestal AC Chargers handle 7-22 kW Level 2 for overnight van charging. For faster turnaround, our Split-Type DC Charging Cabinet scales from 30 kW to 480 kW with modular power modules.

Load Management: Essential at Scale

A 500-van depot with unmanaged charging could pull 3+ MW simultaneously and trigger demand charges of $40,000-60,000 per month. Load management caps site draw and sequences charging to stay within limits. See our guide on what load balancing is and why it matters.

The Telematics Piece

Last-mile delivery runs on data: route optimization, package tracking, driver performance metrics. The charging system needs to talk to the same telematics platform. When a vehicle reports its state of charge and the route optimizer knows tomorrow's delivery density, the charging system can prioritize the vans with the longest routes and deprioritize those with light days.

For more on this integration, see our article on fleet charging and telematics integration.

Real Numbers: A 100-Van Depot

Annual operating cost: roughly $200,000-300,000 including electricity, demand charges, and maintenance. For the TCO math comparing this to diesel, see our fleet charging TCO comparison.

Common Mistakes

1. Underestimating the electrical timeline. A 1 MW+ service upgrade takes 12-18 months. Start the utility conversation before you order a single charger.
2. Buying fixed-power chargers. Your fleet will grow. Modular DC chargers let you add power modules instead of replacing cabinets.
3. Ignoring driver training. EV newbies will plug into the wrong charger, forget to plug in, or report a "broken" charger that's just in sleep mode. Training pays for itself in uptime.
4. No redundancy plan. If one charger fails and 10 vans can't charge, you're short 10 vans tomorrow morning. Have spare chargers or swap modules ready.

Bottom Line

Last-mile delivery is the segment where fleet electrification makes the most economic sense right now. The routes are predictable, the dwell time is generous, and the TCO math has already crossed over for single-shift operations. Two-shift operations require more power and more careful planning but still beat diesel within 5 years.

The hard part isn't the technology — it's the electrical infrastructure, the site layout, and the operational integration. Plan for the fleet you'll have in 5 years, not the one you have today.
