Sustainable Development Goals

SDG 13 – Climate Action, SDG 7 – Affordable and Clean Energy, SDG 9 – Industry Innovation and Infrastructure

Company Overview

ION Energy is a Mumbai-based battery technology company founded in 2016 by Akhil Aryan and Alexandre Collet. The company was established to improve the performance and lifecycle management of lithium-ion batteries used in electric vehicles and stationary energy storage systems.
In 2018, ION Energy acquired Freemens SAS, a French battery management system provider, which brought Alexandre Collet into the company as co-founder and expanded its advanced electronics capability.

In 2019, the company launched Edison Analytics, a cloud-hosted battery lifecycle management platform that combined battery data, embedded electronics and machine learning to monitor and predict the health of lithium-ion batteries. The platform was subsequently restructured into a dedicated digital twin and data analytics product named Altergo, which continues to serve energy storage and electric vehicle operators.

In May 2022, ION Energy divested its battery management system hardware and advanced electronics business to Endurance Technologies Limited, which now operates that unit as Maxwell Energy Systems. Following the divestiture, ION Energy has continued to develop and operate its software-based battery analytics platform, serving utility-scale battery energy storage system operators and electric mobility companies.

The company has worked with organizations including esVolta, a North American utility-scale battery storage developer, integrating its analytics platform across several hundred megawatt-hours of deployed storage capacity. ION Energy has raised early-stage funding from investors including Amazon’s Climate Pledge Fund, YourNest Venture Capital and Climate Capital. The company remains headquartered in Mumbai, India, with Akhil Aryan continuing to be publicly identified as chief executive officer as of mid-2026.

Why These SDGs Matter

SDG 7 is directly relevant because ION Energy’s analytics platform helps extend the usable life and improve the operating efficiency of lithium-ion batteries that store renewable energy and power electric vehicles, supporting more reliable clean energy systems.

SDG 9 applies because the company develops digital infrastructure, including cloud-based analytics and digital twin technology, that supports the battery energy storage and electric mobility industries as they scale.

SDG 13 is relevant because improving the performance and longevity of batteries used in electric vehicles and grid-scale storage supports the broader transition away from fossil fuel-based transport and power systems, which is central to reducing greenhouse gas emissions.

Approach & Methodology

ON Energy’s current product, Altergo, is a cloud-hosted digital twin and data analytics platform for lithium-ion battery systems. The platform ingests operational data from battery management systems and combines it with machine learning models to estimate state of health, predict degradation patterns and flag anomalies before they affect performance.

The digital twin approach creates a virtual replica of each physical battery asset, allowing operators to compare predicted versus actual performance over time. This is used to support warranty management, since operators can attribute capacity loss to specific usage patterns rather than treating all degradation as unexplained wear.

The platform includes an API layer that allows battery pack makers, OEMs and energy storage operators to integrate Altergo’s outputs into their own operational software rather than adopt a fully closed system. Earlier versions of the company’s technology, developed while it also built battery management system hardware, combined embedded electronics with software analytics. Since the 2022 divestiture of the hardware business, the company’s methodology has centered on the software and data layer, working with battery data supplied by client hardware.

This data-driven approach reflects a broader industry practice in battery energy storage, where predictive analytics and digital twin modeling are used to reduce degradation-related financial losses on multi-year, multi-megawatt storage deployments.

Market Position

ION Energy operates in the battery intelligence and analytics segment of the energy storage and electric mobility markets. Its primary customers are utility-scale battery energy storage system developers and operators, alongside electric vehicle fleet operators and OEMs that require visibility into battery degradation and performance. The company’s positioning shifted in 2022 when it divested its battery management system hardware business to Endurance Technologies, refocusing on software-based analytics and digital twin technology delivered as a subscription service. This differentiates ION Energy from vertically integrated battery hardware manufacturers, positioning it as a data and software layer capable of working across different battery chemistries and hardware providers, serving both energy storage operators and electric mobility companies.

Procurement Considerations
  • Confirm compatibility of the Altergo platform’s API with existing battery management hardware
  • Verify current certifications and compliance standards directly with the company
  • Review subscription-based pricing and contract terms for portfolio-scale deployments
  • Assess data security and cloud hosting arrangements for battery operational data
  • Request reference deployments or case studies, such as the esVolta engagement
  • Clarify current corporate structure and branding relationship between ION Energy and Altergo
  • Evaluate onboarding and integration timelines for large, multi-site battery portfolios
Funding, Recognition & Ecosystem
  • Pre-Series A funding of $3.6 million in 2021 from Amazon’s Climate Pledge Fund, YourNest Venture Capital, Climate Capital, Riso Capital and Venture Catalysts
  • Total disclosed funding of approximately $6.16 million across four rounds, per Tracxn
  • Co-founder and CEO Akhil Aryan named to the Forbes India 30 Under 30 list in 2020
  • 2018 acquisition of Freemens SAS (France), which expanded the company’s electronics engineering capability
Natnavi Analysis

ION Energy’s trajectory illustrates a pattern seen among several deep-tech energy startups: an initial focus on hardware, followed by a strategic narrowing toward the software and data layer where recurring revenue and scalability are easier to achieve. Founded as a battery management system provider in 2016, the company’s 2022 divestiture of its BMS hardware unit to Endurance Technologies suggests a deliberate move away from capital-intensive electronics manufacturing toward analytics and digital twin software, marketed under the Altergo name.

This shift positions the company within a growing niche of battery intelligence software supporting the broader transition to electric vehicles and grid-scale energy storage, a segment expected to grow as more lithium-ion assets reach the multi-year point where degradation becomes financially material. The esVolta engagement, covering several hundred megawatt-hours of utility-scale storage, is a concrete indicator of the platform’s use in commercial settings.

At the same time, publicly available information about ION Energy’s current scale, leadership and its precise relationship to the Altergo brand varies across sources. This variation is a reflection of source availability rather than a judgment on the company itself, and procurement teams should verify current organizational details directly with ION Energy before making decisions.
