Elysia - Battery Intelligence from Fortescue

What Elysia - Battery Intelligence from Fortescue does

Elysia is the battery intelligence software division of Fortescue Zero (formerly Williams Advanced Engineering), an Oxfordshire-headquartered subsidiary of Fortescue. Founded as a standalone brand in April 2023, Elysia develops physics-informed, probabilistic battery analytics software that fuses first-principles electrochemical modelling with machine learning to extend battery life, enhance safety, and unlock performance across electric vehicles, battery energy storage systems (BESS), motorsport, and heavy industry. Its dual-product architecture comprises Elysia Cloud (a SaaS analytics platform with lifetime forecasting, safety prognostics, SOC management, and a self-service Simulation Toolkit) and Elysia Embedded (hardware-agnostic BMS algorithms covering SoC, SoH, SoP, always-on balancing, and fault prognosis for OEM integration).

The company operates an enterprise B2B software model with three revenue streams: subscription-based cloud licences to BESS operators, OEMs, fleet operators, and financiers; per-unit or per-agreement embedded algorithm licensing to OEMs and battery system developers; and supporting professional services (commissioning, FAT/SAT). Distribution is primarily through direct enterprise field sales supplemented by a product-led Simulation Toolkit channel and a bespoke API. Elysia serves automotive OEMs (Lotus, JLR), motorsport (Extreme E, LMDh), mining and heavy industry (Fortescue internal deployment on electrified haul trucks), and BESS owners/operators — a customer base materially extended in January 2026 through the acquisition of US-based on-site precision-control specialist Zitara.

Core offering

Elysia develops and sells battery intelligence software that combines physics-informed electrochemical modelling with probabilistic AI to extend battery life, enhance safety, and unlock performance. The company offers two main product lines: Elysia Cloud, a subscription-based SaaS platform providing lifetime forecasting, safety prognostics, and performance insights to fleet operators, BESS owners, and OEMs; and Elysia Embedded, a suite of hardware-agnostic BMS algorithms (SoC, SoH, SoP, Balancing, Fault Prognosis) licensed to automotive OEMs and battery system developers for integration into their own battery management systems.

Product overview

Elysia offers a dual-product architecture comprising Elysia Cloud (cloud-based battery intelligence platform) and Elysia Embedded (hardware-agnostic BMS algorithm suite). Elysia Cloud turns standard telematics data into insights for lifetime forecasting, safety prognostics, and performance optimisation, and includes the Simulation Toolkit with Web App, Bespoke API, and Simulink Integration. Elysia Embedded provides on-device SoC, SoH, SoP, Balancing, and Fault Prognosis (Beta) algorithms deployable to standard automotive-grade hardware. Both products are powered by physics-informed AI and probabilistic statistical methods developed from over a decade of motorsport and real-world battery deployment experience. The portfolio spans automotive (micromobility to mining trucks), energy storage (BESS), and was expanded in 2026 through the acquisition of Zitara (on-site precision control).
