Fleet charging built around the departure schedule
Turn route energy, parking windows and available power into a fleet charging brief, from overnight AC to DC charging between shifts.

Fleet charging starts with the energy vehicles need before their next departure. Record routes and parking windows before selecting power. A mix of overnight AC and DC for shorter stops may be appropriate, but the right combination depends on the vehicles, schedule and available supply.
Build a vehicle-and-shift schedule
| Input | Why it matters |
|---|---|
| Vehicle model and charging inlet | Establishes AC/DC compatibility and charging limits |
| Energy needed before departure | Defines the charging task rather than a nominal battery size |
| Arrival and departure times | Shows which vehicles can share a charger over time |
| Simultaneous vehicles | Reveals the busiest charging window |
| Site demand and energy tariff | Helps compare scheduling options and available capacity |
| Operational reserve | Captures the fleet's own recovery and backup policy |
For example, four vehicles each needing 30 kWh require 120 kWh in total. Spread evenly across a six-hour window, that is 20 kW on average before charging losses and scheduling constraints. This arithmetic is a discussion aid; it does not specify the chargers or electrical installation.
Compare the charging windows
- Long overnight dwell: evaluate managed AC against each vehicle’s AC capability.
- Intermediate stops: consider compact DC where AC cannot meet the required window.
- Shorter turnaround: review higher-power DC against the vehicle’s actual charging curve and site capacity.
DOE’s fleet guidance discusses route needs, charging locations and networked management. It also emphasizes matching infrastructure to the actual fleet. DOE fleet planning.
Plan for interrupted operations
Define what happens when a charger is unavailable, a vehicle arrives late, communications fail or the site limit is reduced. Assign departure priorities and agree how drivers or dispatchers see charging status. Do not assume that adding more outlets adds more utility capacity.
Confirm the system before rollout
Use load management to specify site control and OCPP acceptance to test the management interface. Include DC outlet-sharing tests where relevant.
Ampvoya is reviewing its equipment range and does not currently list AC or DC charger models. Vehicle compatibility, software functions, energy delivery, backup arrangements and service coverage must be agreed for the actual fleet project.
