Home / Solutions / Fleet Depot Charging
Fleet EV charging infrastructure for depots from 48-vehicle logistics hubs to 200-bus municipal yards. DC fast chargers, dynamic load balancing, OCPP integration and depot design support — built for maximum uptime and lowest total cost of ownership.
Challenges
Most depots were designed for lighting and basic equipment — not 50+ vehicles charging simultaneously. A naive installation can require 3× the available grid capacity, triggering costly utility upgrades that take months and add six-figure costs.
Unmanaged simultaneous charging at shift change creates demand spikes that can double or triple your monthly electricity bill. Without smart scheduling, the cost savings of electrification evaporate into utility demand charges.
Every hour a fleet vehicle spends charging is an hour it is not generating revenue. Legacy AC charging requires 7+ hours per vehicle, forcing single-shift operation. DC fast charging is essential for multi-shift fleet utilization.
Determining the right number and mix of AC and DC chargers for your fleet size, duty cycles, and operating hours is the single most consequential design decision — get it wrong and you face either charger queues or stranded capital.
Chargers must talk to your fleet management system via OCPP. Without real-time SOC data, charge scheduling, and per-vehicle energy reporting, you cannot optimize routes, shifts, or energy costs across an electric fleet.
Depot chargers operate in harsh conditions — tropical heat (42°C+), humidity, dust, and 24/7 duty cycles. Standard commercial chargers fail under these conditions. Depot-grade equipment requires wide-voltage input and industrial protection ratings.
Recommended Chargers
Match your fleet profile to proven DC fast chargers built for 24/7 depot operation — from mid-power units for light-duty vans to liquid-cooled superchargers for bus and mega depots.

Proven Results
A Thai logistics operator electrified 48 delivery vehicles at their Bangkok depot. Dynamic load balancing avoided a THB 2.8M grid upgrade by distributing 200A across all chargers in real time. DC fast chargers served priority refrigerated vans with 45-minute turnaround.

There is no universal number — it depends on fleet size, duty cycle and shift pattern. As a planning guide, the depot configurations costed on this page run 12× AC 7 kW plus 3× DC 60 kW for a 10–30 vehicle last-mile depot, 30× AC 7 kW plus 6× DC 120 kW for a 30–80 vehicle regional logistics depot, and 60× AC 7 kW with 12× DC 240 kW and 2× DC 360 kW for an 80–200+ vehicle multi-shift hub. Matching the AC-to-DC mix to your vehicle duty cycles is what avoids both charger queues and stranded capital.
In most depot projects, yes. Dynamic load balancing distributes the current a site already has across every charger in real time instead of letting all vehicles pull maximum power at once. At the 48-vehicle BrightRoute depot in Bangkok this avoided a THB 2.8M grid upgrade by spreading 200 A across the installed chargers — and the same control prevents the shift-change demand spikes that can double or triple a depot electricity bill.
It depends on the charger class. AC 7 kW units restore most vans and light vehicles overnight, which suits long-dwell parking between shifts. For vehicles that cannot wait, 60–80 kW DC chargers turn a medium-duty van around in 45–90 minutes, and the 120–240 kW dual-gun units deployed at our Accra depot take a commercial EV from 20% to 80% in about 42 minutes — the speed multi-shift operation requires.
