Refuelling an Electric Fleet in Under a Minute
Sigma swap cabinets keep charged packs waiting where riders already are. A rider docks a depleted battery, takes a full one, and rides on, while every slot reports charge state, temperature, and revenue back to the platform.
How the system works
The Station
Every Bay Is a Metered Asset
Cabinets ship in 4, 8, and 12 bay configurations and charge packs in parallel with per-slot current control. Each bay knows which pack it holds, its state of charge and health, and who took it last, so operators can plan cabinet placement and pack ratios around real demand rather than guesswork.

Capabilities
Charging Infrastructure That Pays for Itself
Cabinets, packs, payments, and telemetry deployed together so a swap network can be operated as a business from day one.
Modular Swap Cabinets
Standardised bays that accept the same LFP packs used across the Sigma e-bike fleet, expandable as demand grows.
Solar-Powered Stations
PV and storage supply where the grid is weak or expensive, so charging cost per kilometre stays predictable.
App & RFID Access
Riders unlock a bay from the app or with a card, and subscriptions or wallets settle the swap automatically.
Slot-Level Telemetry
Charge state, temperature, cycle count, and fault flags for every pack and every bay, streamed live.
Pay-Per-Swap Billing
Prepaid wallets, daily plans, and per-swap pricing, reconciled with mobile money and card payments.
Safety & Protection
Cell-level BMS enforcement, thermal cut-off, surge protection, and locking bays that only release an authorised pack.
