Our solutions
About:Energy supports battery design decisions across a wide range of industries, each with unique performance, safety, and validation challenges. Select your industry to explore the workflows and tools most relevant to your application.
Pack Concept Benchmarking
Compress evaluation timelines
Cut months of physical testing into weeks with validated digital benchmarking of pack performance.
De-risk platform decisions
Compare pack concepts under realistic conditions before gateways to avoid costly mid-development changes.
Reduce testing spend
Eliminate expensive prototyping work on unsuitable cell and pack concepts by screening digitally first.
Accelerate development
Make confident design decisions months earlier, keeping your development schedule on track.
Validate then scale
Test pack-level performance digitally before committing resources to manufacturing and supply chain.
Minimise waste
Focus physical testing only on the conditions and pack concepts that matter.
Use our Model-Based Design products to iterate on cell selection and pack design in seconds
Cell Selection
The right cell selection starts with the right data.
Voltt gives you instant access to validated performance data across the latest commercial cells so you can compare, evaluate and select the right cell for your application before committing to a design.
-
Compare the latest commercial cells side by side
-
Evaluate real-world performance across use cases
-
Make confident early-stage design decisions, fast
Pack Design
Validate your pack design before you build it.
Our simulation-ready pack models deliver high-fidelity electrical, thermal and degradation predictions to optimise fast charge strategies, define warranty limits and validate pack designs before committing to hardware.
-
Model electrical, thermal and degradation behaviour in your pack
-
Integrate directly into existing simulation workflows
-
Validate performance and lifetime at the system level
Compatible with any simulation environment, ready to use from day one.
Case Studies
Our customers are the industry leaders who are exploiting the advantages of model-based-design to bring the best battery systems to market. Read about the handful of customers with whom we have a public relationship.
“This is why having the model from About:Energy is so critical and useful to us. Customers can tell us their duty cycle, their powertrain, and what they want to do with their car. We can then run that information through the About:Energy models and immediately say how the pack will behave.”
Kevin Ukoko-Rongione, Chief Engineer - McMurtry Automotive
"We want to deliver the best drone battery solutions across multiple platforms and give customers a rapid route to market. About:Energy accelerates our cell selection and design processes, helping us quickly find optimal configurations for weight, flight-time and thermal trade-offs."
Tobias Kahnert - CEO of EFT Mobility
Why About:Energy
Built By Engineers, For Engineers
At About:Energy we believe the best engineering decisions come from deep understanding, not black-box outputs. That is why we publish free access to validated cell data, engineering resources and technical reports, giving customers and the wider battery community full transparency into how our models are built, tested and validated.
High-Performance Battery Report
Our High-Performance Battery Report analyses 400+ commercial cells to identify the highest energy and power options for demanding applications. Compiled from our in-house testing and expertise, it gives engineers a free, authoritative reference for understanding the latest cell landscape and making informed early-stage design decisions.
Student Sponsorship
We sponsor over 80 student motorsport teams around the world, providing validated cell data and simulation models to support cell evaluation and pack design. It is how we invest in the next generation of battery engineers and give them the same tools used by industry leaders.
Globally recognised as the worlds third-party verifier of cell technology by both pack designers and cell manufacturers. We combine deep expertise in battery testing and simulation with state of the art model-based-design for battery packs.
In-house state-of-the-art lab
PhD-led team - we become your experts
White-box engineering approach

01
Define your Application
Share your pack requirements, mission profile and design constraints so we can focus the search on what actually matters.
02
Explore the Right Cells
Browse validated performance data across the latest commercial cells, filtered to your use case rather than generic spec sheets.
03
Request any Cell
Don't see the cell you need? Share the spec and we'll add it to the library within 8 weeks, fully tested and validated.
04
Select with Confidence
Compare simulation results across energy density, thermal and degradation performance and make your design decision backed by real data.
How It Works
Frequently Asked Questions
Our models are white-box and come in physics-based and empirical forms, so you get the right model for your use case. Both are built from controlled electrochemical testing rather than fitted to published datasheets, meaning they accurately predict electrical, thermal and degradation behaviour under your real operating conditions, not just nominal ones.
All of our customers have in-house simulation and test capability. What they don't have is the time or resource to characterise every cell, build validated models and maintain those workflows alongside active development programmes. We plug directly into your existing setup so your engineers stay focused on design, not data collection.
If your cell is already in our library, model delivery is immediate. If we need to characterise your cell, we complete full testing and delivery within 8 weeks from receiving samples at our London lab.
Our models are delivered in your platform of choice — MATLAB/Simulink, Python, COMSOL, GT-Suite and more. They drop into your existing workflow without rebuilding from scratch.
Our customers span automotive, aerospace, drones, high-performance motorsport and defence. If your application involves a lithium-ion battery pack and performance, lifetime or safety matter, our models are relevant.
Across cell selection and pack design, customers report up to 70% reduction in time and cost. Rather than spending engineering resource on collecting data, building models and setting up workflows, teams can focus on what actually matters: designing better battery systems and getting to market faster.
