Mobile energy must behave like infrastructure.
Dispatchable charging is useful only when the network can discover demand, qualify sites and equipment, reserve capacity, support the asset, reconcile measured delivery and preserve an accountable record. FE-OS coordinates those responsibilities without pretending to own every vehicle, charger, site or provider.
Proposal before execution.
Each stage answers a different operational question. A stage may advance the proposal, request better information or stop the workflow with a reason. Passing one stage never bypasses the authority required by the next.
The core does not directly command machinery.
The current architecture cannot issue governor, CAN/Modbus, charging, rerouting, reservation, billing or payment commands. Provider adapters remain separately authorized, scoped, revocable and observable.
One transaction identity across operations.
Every layer refers to the same request, proposed mission and resulting service transaction. Responsibility identifies the operating truth that layer owns. Action describes the controlled work performed with that truth. Evidence is the durable record required to explain, audit, reconcile or correct the result.
| Layer | Responsibility | Action | Evidence |
|---|---|---|---|
| Demand | Fleet need and energy objective | Open and version the charging request; validate consent, timing and the requested energy outcome. | Consented request + baseline telemetry |
| Supply | Asset capability and reserve | Qualify compatible mobile capacity and propose an allocation without overstating availability. | Operator attestation + fresh equipment telemetry |
| Place | Authority, circulation and safety | Validate the site, bay, access path and proposed operating window before matching it to a mission. | Site authority + verified-site policy |
| Execution | Mission and state transitions | Advance an approved mission through authorized adapters and record every accepted, rejected or failed transition. | Signed approvals + state-event audit |
| Commerce | Delivery, tax and settlement | Reconcile metered energy, determine applicable tax and create balanced settlement entries. | Meter evidence + tax determination + ledger |
| Uptime | Technician, parts and support | Open the support case, diagnose and repair the asset, then document its authorized return to service. | Repair order + service evidence + return-to-service approval |
