Company profile
researched Aug 2026ION Energy is an energy-technology company that builds electronics and software for battery-powered systems. Its original flagship product is a smart battery management system (BMS) using proprietary algorithms intended to improve lithium-ion battery life and performance, sold as hardware or licensed as technology to OEMs and battery pack makers in electric vehicles and stationary storage.
In 2019 the company launched a battery analytics product, initially called Edison Analytics and later renamed Altergo, which is a digital twin platform for battery intelligence aimed at owners and operators of deployed battery fleets. Altergo's architecture spans data ingestion (field, lab and transactional data, batch or real time, via API), modeling and instantiation of digital twins representing hierarchical physical systems, clustering of twins into operational groups, prediction and simulation using AI/ML and semi-empirical models, and an application/insights layer. Platform modules include state-of-health and state-of-function estimation, warranty and performance management, reporting and visualisation dashboards, an SDK/API integration layer, and a "Function Manager" that runs standard or custom functions against digital twins on a schedule.
Stated use cases include predictive maintenance and optimisation, real-time performance monitoring and control, design and simulation for new battery technologies, EV range estimation algorithms, motor and powertrain performance analysis, thermal management optimisation, intelligent charging and energy management, grid balancing and demand response, and asset lifecycle management. Current site messaging positions Altergo as an intelligence layer for grid-scale battery assets, claiming recovery of 1.5%+ of usable capacity and 15% longer asset life across fleets operating behind a single dispatch command.
Founding story
ION Energy was founded in 2016 by Akhil Aryan and Alexandre Collet, with a stated mission of accelerating the transition to an all-electric future through advanced electronics and software for new energy companies.
Business model
ION Energy operates two connected lines of business: hardware/firmware sold to manufacturers, and subscription software. Battery management systems are sold either as a product or as a technology license to OEMs and battery pack makers building lithium-ion batteries and electric vehicles. The Altergo battery intelligence platform is positioned as a SaaS-style offering for owners and operators of deployed battery fleets, with enterprise trials, API/SDK integration and dashboard-based reporting. Company statements at the time of its 2021 raise emphasised growing the software (SaaS) side of the business.
Revenue comes from sales of battery management system hardware, technology licensing to OEMs, and software subscriptions/enterprise contracts for the Altergo battery intelligence platform.
Traction
As of July 2021: 75+ OEM/customer relationships across 15 countries, 60,000+ smart BMS units deployed in EVs and stationary storage, 700+ MWh of storage managed via Altergo, a $15M+ order pipeline, and a team of 70 with plans to reach 125+. esVolta committed to deploying Altergo across a 581 MWh storage portfolio. Published case studies cite $112k saved in liquidated damages, 4x faster time to market via automated R&D, and 2x warranted life on intercity electric buses.
Latest developments
The company's website now centres on the Altergo platform as an intelligence layer for grid-scale battery assets, with modules for digital twins, warranty and performance management, reporting, APIs and state-of-health/state-of-function estimation, and references the acquisition of Maxwell Energy by Endurance Group.

Market position
By mid-2021 the company reported serving more than 75 customers across mobility and energy in 15 countries, over 60,000 smart BMS units deployed in electric vehicles and stationary storage, and more than 700 MWh of battery storage managed in the cloud through Altergo, alongside a stated order pipeline of over $15 million. It has been listed alongside energy storage companies such as Recurrent Energy, Zenobe Energy and Eos Energy Storage.
The company positions its proprietary BMS algorithms and the Altergo digital twin layer as a combined hardware-and-analytics approach to battery life and performance, arguing that in large fleets estimation errors compound and the weakest unit constrains system output. Differentiation claims centre on accuracy of state-of-health and state-of-function estimation, digital twins that capture hierarchical relationships in physical systems, and an open API/SDK surface exposing full platform functionality for integration into customer workflows.
Technology
The platform is built on battery digital twins fed by field, lab and transactional data through a batch or real-time ingestion API. Twins can be grouped into operational clusters, and AI/ML plus semi-empirical models drive predictions and simulations, including state-of-health and state-of-function estimation. A Function Manager executes standard or custom functions on twins on configurable schedules, and results are surfaced through customisable dashboards or consumed via APIs and SDKs. On the hardware side, the company's BMS relies on proprietary algorithms intended to improve battery life and performance.
Go-to-market
Sales are enterprise and direct: BMS hardware and technology licenses to vehicle and battery-pack OEMs, and platform engagements with battery fleet owners, storage developers and operators. The company publicises named partnerships and portfolio-wide deployments (for example with Ray Electric Motors and esVolta) and offers an enterprise trial sign-up, case-study downloads and contact-driven inquiry flows on its website.
Original equipment manufacturers developing lithium-ion batteries and electric vehicles, battery pack makers, EV OEMs, and owners and operators of large battery fleets and grid-scale energy storage systems, including energy storage developers.
Geography
Headquartered in India (announcement datelined Mumbai) with operations in France and the United States as of 2021. Customers spanned 15 countries, including India, France, Spain and the U.S., and the 2021 funding was intended in part to expand the software business in North America and Europe.
History
The company was founded in 2016 and by 2021 described itself as headquartered in India (Mumbai) with operations in France and the United States. In 2019, as BMS deployments grew, it launched a dedicated battery analytics product, Edison Analytics, later renamed Altergo. In 2020, U.S. energy storage developer esVolta said it would deploy Altergo across its full 581 MWh battery storage portfolio. In July 2021 the company raised $3.6 million in Pre-Series A funding, with Amazon's Climate Pledge Fund making its first India investment, and added Anup Menon of Bank of America to its board. More recently the company's site presents Altergo as its primary offering, focused on grid-scale battery assets.
