Connected to the utility data your fleet needs
Celaxis integrates with three critical data categories: utility tariff APIs for live rate intelligence, fleet telematics for real-time SOC and departure data, and EVSE networks for charge command dispatch.

Live rate intelligence from 200+ US utilities
The optimizer is only as accurate as its tariff data. Celaxis maintains live feeds from 200+ US utilities, with each feed modeled at the level of granularity the utility actually uses to bill: 15-minute demand intervals, seasonal TOU window transitions, tiered energy blocks, and ratchet clauses. Rate data is not scraped — it is maintained per tariff schedule, with change tracking on utility rate filings.
Real-time SOC and departure data from your fleet
The optimizer needs two live inputs per vehicle: current state of charge and next departure time. Celaxis pulls these via standard telematics integrations or direct API connections.
What we pull per vehicle
Command dispatch to your charging network
Optimized schedules push to your EVSE network management system via OCPP or REST, authorizing and de-authorizing charge sessions in real time as tariff conditions change.
OCPP 1.6 / 2.0 Support
Standard OCPP 1.6 and 2.0 protocol support covers the majority of commercial EVSE hardware deployed in North American depots today. Celaxis acts as the CSMS (Charge Station Management System) and sends ChargingProfile payloads to each station — including granular setpoint schedules and power limit profiles for hardware that supports Smart Charging.
REST Network Management APIs
Direct API integrations with ChargePoint, Blink Network, and other major EVSE management platforms for fleets already using a specific network provider.
Power Limit Dispatch
Beyond on/off control, Celaxis sends granular power limit setpoints (kW) to chargers that support OCPP Smart Charging — enabling precise demand shaping across the depot.
On-Premise Deployment
For fleets with network restrictions, Celaxis can deploy an on-premise dispatch agent that handles the EVSE communication layer while optimization runs in the cloud.
Dispatch schedule sync keeps charging invisible to operations
Celaxis reads departure schedules directly from your fleet management system, so the optimizer always works against actual route requirements — not static assumptions. Drivers and dispatch operators have no interface with the charging layer. Optimization runs in the background; the result is vehicles with the correct SOC at the start of every shift.
Your utility isn't listed. Your EVSE hardware isn't in the catalog.
We add new utility tariff feeds and EVSE integrations on request. Most new utility feeds are live within 2–3 weeks of the rate schedule filing. Contact us with your utility name, service territory, and the tariff schedule your depot is on.
