Breathe Charge
Adaptive charging software.
Real-time performance.
Existing charge control strategies are sub-optimal.
Today, the battery industry is hampered by trade-offs. Competing demands of charge speed, lifespan, range and safety are precariously balanced in a bid to deliver peak performance, at the lowest possible cost.
Development is protracted and costly, dependant on complex empirical tuning and hard-coded lookup tables. Performance can be left on the table, with charging strategies that fail to safely extract the most out of a battery at all stages of its life. While conversely, cells can be pushed too far, leading to unnecessary risk and safety issues.
When we founded Breathe, we were dissatisfied with decades of failed attempts at model order reduction. So we started from scratch and built a unique battery model architecture to solve real-life charging problems, quickly and effectively. Breathe Charge: embedded adaptive charging software that makes batteries better.
Adaptive charging software.
The shaded region represents the replenished range of an EV during a charging session.
Breathe Charge is embedded adaptive charging software that is faster, more flexible and more cost effective to implement than traditional ways of developing charge control.
Operating in real-time and on device, Breathe Charge enhances charge performance with nothing but software. No hardware changes needed.
Extremely lightweight, Breathe Charge introduces physics-based estimation into your existing compute and memory budget.
Making more of atoms, with bits
Volvo ES90
186 miles in 10 minutes and 10-80% in 20 minutes. Breathe Charge is integrated into the Volvo ES90, the fastest and most efficient Volvo charging system yet.
Bang & Olufsen Beo Grace
By embedding Breathe’s software into product development, Bang & Olufsen can design battery systems that last longer, perform more reliably, and reduce environmental impact.
OPPO A5 Pro
Seamlessly integrated into Oppo’s new product development process, Breathe Charge features on over 30 models of OPPO smartphones, to enable ultra-fast charging at up to twice the battery life.
Why Breathe Charge?
Unlock performance
Breathe Charge safely accesses untapped performance by managing charging current using physics-based estimation.
Improve headline metrics and day-to-day user experience, deliver an always optimal charging experience to the end user with Breathe Charge.
Be resilient
Market demands, performance targets, and battery hardware are constantly shifting.
Breathe Charge provides the flexibility to pivot your charging strategy late in the development without leaving performance on the table.
Develop faster, cheaper
Improving fast charging through hardware can cost over $1 million per minute reduced, while adding higher BOM costs into every product. For EVs, this can be upwards of $200 per vehicle.
Breathe Charge delivers the same performance at a fraction of the cost, all through software. Reshape how you work with cell suppliers and take ownership of performance and timeline.
How it works
Estimate
Physics-based estimation of anode potential and electrode overpotential, second-by-second.
Control
Closed-loop control of the charging current to actively manage battery states in real time.
Adapt
Inherently adaptive to battery health, cell-to-cell variability, operating conditions, and degradation pathways. No parameter updates needed.
Key features
See the full picture
Breathe Charge can identify the limits of what charging performance your cell is capable of.
Enabled by control of battery states, this pareto frontier of performance is constructed so you can make informed, product-level decisions about the right charging experience to provide to your end user.
This performance can be deployed with Breathe Charge, as simply as drag and drop.
Calibratable in development
Customisable on device
Direct control of your margins
With Breathe Charge, the internal states of your battery cell are actively controlled for on a second-by-second basis. This means in every instance you are getting the optimal charging for your cell.
Traditional charging strategies have periods of underutilisation, where performance is left on the table, and also over extension, where the cell is pushed beyond its limits, introducing risk of accelerated ageing and safety.
Seamless scaling
Breathe Charge has been designed to be deployed. That means it is effortless to scale to the number of cells in your pack, mindful of the sensors and estimators you already have available.
Partnering with you, we define zones of estimation to make sure every cell, strongest to weakest, is considered.
On a vehicle, this can look like 160 instances of estimators running in real-time, or on a laptop, 3.
An industrialised parameterisation pipeline
In our laboratories, parameters for Breathe Charge can be generated in as little as two weeks. This ensures new cell samples and design updates fit seamlessly into product development, without impeding timelines or delaying launch.
We have parameterised more than 75 cell models, from under 20 mAh to over 200 Ah. That experience spans every major form factor and the mainstream chemistries, including LCO, NMC, LFP, silicon oxide, silicon graphite, and pure graphite. Whatever the roadmap, Breathe Charge keeps progress moving.
Proven in production
Computationally lightweight
Breathe Charge embedded software is delivered as a statically-linked compiled library, which is easy to integrate into your battery management system. Our PHI X2 physics-based model architecture is incredibly computationally light, making it easy to integrate within your existing computation and memory budgets.
Example memory requirements for an automotive pack-level integration of 160 instances are 35 kB of RAM, statically allocated, 40 kB of ROM (program memory) and 0.5 kB of NVM (non-volatile memory).
Compatible with your existing hardware
For automotive applications, Breathe Charge is delivered as AUTOSAR-compliant embedded software, compatible with automotive BMS ECU microprocessors.
For consumer electronics and power tools applications, it is delivered as a compiled, statically-linked C-library compatible with all common 32/64-bit CPU architectures. It works with any fuel gauge/charger ICs, including successful integrations with TI BQZ40z50-R3 and Analog Devices MAX17262.
Quality and standards assured
We pride ourselves on building software according to rigorous automotive quality standards, such as ASPICE level 2, and are committed to providing quality products and continuous improvement.
Enjoy peace of mind knowing you’ll get value for money and high-quality results - on-time and with low risk - through an ISO-certified environment with ISO 9001 (quality management) and ISO 27001 (data security).
Get started with Breathe Charge.
Our performance mapping service shows the best balance of performance your battery can achieve with Breathe Charge. By exploring trade-offs between charge time, degradation, and other performance attributes, we define the optimal charging envelope, maximising charging speed while protecting durability and safety.
Powered by Breathe Charge’s real-time control of internal battery states, the performance map exposes untapped performance margins and highlights where value can be unlocked through smarter charging.
Delivered in as little as 3-weeks, the service includes cell parameterisation and control strategy calibration. With optional degradation testing to link performance with aging, you’ll get a validated performance map, data to prove what’s possible, and a ready-to-use calibration file for deployment with Breathe Charge.
