The battery development
process is unsustainable.
process is unsustainable.
Designing high-quality battery powered experiences requires a delicate balance of great cell design, seamless system integration and optimal control.
Yet today, this process is unsustainable. Iterative, slow, and costly — constrained by ever-more empirical testing, fragmented data and limited supplier transparency. The result? Inefficiencies, suboptimal design decisions, and batteries that don’t reach their full potential.

Extract the power within
As lithium-ion batteries age, their capacity and performance decline due to chemical aging and plating. That’s because traditional battery management relies only on what’s measurable on the outside, terminal voltage, and not the internal components that really matter.
At Breathe, our patented technology provides crystal clear visibility of what is happening on the inside, exploiting this visibility to control the battery in real-time to extract more performance, increasing its safety and longevity in the process.
This is the power behind Breathe Charge and Breathe Life.

Existing simulation tools need significant resource and infrastructure to be effective. Without the right parameters, outputs can be unreliable and of little value. They are unable to give meaningful answers out of the box, often requiring additional wrappers, workflows or environments.
Good simulation software should make life easier. It should abstract you from distracting details to help you deliver results reliably, quickly and at scale.
We’re on a mission to make great simulation tools accessible and affordable. So, we gathered some of the world’s leading experts in battery simulation to build a tool that, as engineers, we wish existed. That's why we developed Breathe Model.
Access all the evidence you need to make more informed battery system decisions. Release yourself from the constraints of empirical testing with abstracted, high-level simulations, or go deep to explore and understand cell physics. Fully parameterised and ready for you.

Revealing the full potential of your battery is a challenge. But do so successfully, and you might find you’re underutilising your battery, that you’ve pushed it too far, or that a more desirable balance of performance was hiding just around the corner.
So, we put our 190 years of experience in electrochemistry, adaptive charging, and modelling to work, to show you just how much your battery is capable of with our interactive performance mapping report.
Produced using our unique method, Breathe Map reveals the balance between your cell’s charging performance attributes by uncovering how these are linked to the battery’s internal states. Gain the visibility you need to effectively rebalance performance, from developing better control strategies to selecting the right cell for your system.

Grounded in physics
Our physics-based approach means we can analyse, control, and experiment with insight into the states that matter most during fast charging.
Through mapping out the different ways each state can be managed during charging, we produce a Breathe Map, where the impact of each internal state on charging performance is revealed.
This physics-based foundation gives you full traceability of why different balances of performance are and are not possible.

Actionable results
Breathe Map is an interactive report that lets you explore how charging performance attributes of your battery – charge time, cycle life, charge time evolution and thermal load - can be balanced, backed by real data.
Performance boundaries will be identified, indicating the limits of your battery and giving you the reference point so you know just how close to the limit your current charge strategy places you.
We give you visibility of how all this performance is achievable through management of the internal states of your battery. This lets you know what factors are limiting, which are underutilised, and how to deploy this performance into your system.

The current tools used to develop a fast charge strategy are convoluted. Look up tables put layers of abstraction between the original design intent and how the battery is ultimately controlled. Iterative and lossy, this approach to controlling batteries is slow, costly, and results in imprecise control.
As a result, the cost of delivering performance rises, as does the risk that the performance delivered doesn’t meet your requirements, or worse, the imprecision means your cell is operating on the edge.
We know this isn’t good enough. So we built Breathe Charge to solve it. Our adaptive charging software controls your battery’s internal states in real time, so you can have confidence you have the optimal charging strategy at every moment.
More precise. More efficient. More informed.

Volvo Cars is reducing the time it takes to charge its new generation fully electric cars - starting with the ES90 - from 10-80% state of charge by up to 30% with Breathe Charge.
“Differentiated, premium user experiences are enabled by the optimal, safe and reliable operation of battery systems. Embedding lookup tables and profiles of charge current as functions of temperature, state-of-charge and even state-of-health is no longer sufficient.
Adaptive charging, enabled through an embedded and real-time physics-based battery model, is now the new standard. We selected Breathe Charge because of its maturity, and we’re delighted to take advantage of the opportunity to lead the transition to adaptive charging.”

Flexible development
Designing a charging strategy with Breathe Charge is intuitive and simple. Instead of trying to populate 100’s of look up table points, you define the threshold each internal state should be controlled to and go.
Changes to market demands, battery design mid-development, or regulations can trigger the need to re-develop a charging strategy. Simple and intuitive solutions enable flexibility. Design a new strategy that manages your battery’s internal states, and see it come to life with Breathe Charge. The result? You can operate with the speed and precision not possible when needing to translate that design through the generation of imprecise look up tables.

Real performance
More range in 10 minutes, more range on a full charge after 8 years of use – fast charging is performance you can feel. But the charging experience is multi-dimensional. Battery temperature, initial state of charge, how the battery ages, how aged the battery is; these factors all dictate how carefully and quickly your battery is charged.
Breathe Charge adapts to the battery in real time, across all these dimensions. No matter what state your system is in when it starts to charge, Breathe Charge will deliver the ideal battery current. No longer will there be sub-optimal ways a battery can start charging. Instead, users will get to experience everything their battery has to offer, no matter the weather.
