EV Fleet Charging Intelligence

Stop paying peak-rate penalties for morning departure

Celaxis schedules your fleet's charging windows against live utility tariff feeds — shifting load automatically without touching dispatch.

Three steps from tariff feed to departure guarantee

Celaxis connects to your utility's live TOU calendars and your fleet's telematics, then runs an optimizer that places charge windows where rate is lowest — while guaranteeing every vehicle hits its required state of charge before departure.

Built for the complexity of real fleet charging

Real-time Tariff Feeds

Live TOU rate calendars from 200+ US utilities. Demand period windows, ratchet clauses, seasonal rate changes — all ingested automatically so the scheduler always works against current rates.

Dispatch Guarantee

Algorithm enforces state-of-charge floors at each departure window. Optimization never overrides operations — if the grid can't supply off-peak charge in time, the system charges on-peak rather than miss the window.

Demand Charge Shield

Tracks 15-minute interval peaks across all chargers simultaneously. Spreads load to avoid kW spikes that reset your monthly demand billing — the highest-impact lever in commercial utility bills.

Fleet-Scale Scheduling

Handles 5 to 500 vehicle depots, multi-site operations across multiple utility zones. Single pane of glass for your entire charging estate, with per-site optimization running independently.

Command your fleet's energy, not just its schedule

The Celaxis scheduling dashboard shows charge session timelines, live tariff rate overlays, and demand threshold meters — all in one view. See exactly where you're saving and why.

Your fleet's energy cost is a scheduling problem. We solved it.

Demand charges are set by the highest 15-minute draw in your billing period. That window is schedulable. We schedule it.
