Your depot transformer has a limit. Fleetvolts respects it.
For fleet operators managing depot power capacity alongside vehicle charging. Fleetvolts builds a power profile for your site and ensures charging sessions never push the combined load past your transformer capacity or demand threshold.
Three depot power problems that get expensive fast
-
Transformer overload risk
Installing 30 Level-2 EVSE on a depot originally sized for diesel fueling is an electrical capacity problem. The transformer serving your site has a kVA rating that predates your EV program. Fleetvolts models your depot's available headroom and enforces a hard ceiling on combined charging load, so no scheduling run can push the site into overload, even if every vehicle returns at the same time.
-
Demand charge minimization
Utility demand charges are billed on the single highest 15-minute interval draw in a billing period. One evening where 20 vans all start charging at 6:01 PM sets a peak that appears on the bill for the entire next month. Fleetvolts staggers session start times across the return window, smoothing the depot ramp and keeping that 15-minute peak measurably lower.
-
Load shifting to TOU valleys
Time-of-use tariffs vary, often by 2x to 3x between peak evening rates and overnight off-peak rates. Fleetvolts shifts the majority of charging load into the cheapest hours while holding a hard constraint: every vehicle must reach its minimum SOC before its next departure. Cheap overnight kWh plus lower demand peaks is where most of the electricity cost reduction comes from.
Tell Fleetvolts about your site once
Set up your depot profile: transformer kVA rating, number and power level of EVSE stations, connector types on each bay (J1772, CCS), and your utility tariff structure, whether flat rate, time-of-use, or a demand-metered commercial tariff. Fleetvolts holds this profile as the constraint envelope for every scheduling run. When your tariff changes or you add chargers, update the profile and the next run reflects it.
Real-time control, not day-after reports
-
Live power draw monitoring: Current depot load versus the kVA ceiling, updated on each OCPP session heartbeat. Operators see how much headroom remains before the limit at any point in the night.
-
Automatic session throttle: If combined live load approaches the transformer ceiling, Fleetvolts sends a SetChargingProfile command via OCPP to reduce current on lower-priority sessions. No operator action required.
-
Monthly demand charge report: Track your 15-minute interval peak each billing period and compare it against prior months. See directly how schedule decisions moved the peak.
Depot charging questions
Depot power under control. Now get the per-vehicle prediction right too.
Managing transformer capacity is one half of the problem. The other half is knowing exactly how much each vehicle needs before it leaves, so charge windows are sized correctly and nothing departs short. See how the fleet operators solution handles the per-vehicle side.
