Charge & Life
Faster charging. Longer life.
A unique charging
Nobody is remembered for 'best compromise'. Fast charging, high capacity and long life together are the holy grail of the battery world. But stepped charging profiles stand in the way, leaving you, as product leaders and battery experts, forced to choose.

Adaptive charging, which dynamically adjusts the charging current across both the state of charge and state of health windows, indicates the ideal charging current at every moment so you can extract even more from your existing batteries.

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. 

Faster charging.

Volvo case study 30%
Volvo Cars will reduce the time it takes to charge its new generation fully electric cars 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.

Frequently asked questions
How do Breathe products work?
Breathe’s products, Breathe Charge and Breathe Life, are embedded software functions installed on the battery management system that inform the charger what current to supply the system during charging.
Breathe's software works by analysing electrochemical states in real-time to extract maximum performance from the battery system while at the same time protecting its lifetime. 
Do Breathe products require any additional hardware?
No. Breathe’s embedded software functions are hardware agnostic, integrated with the device’s existing microcontroller or the vehicle’s battery management system.
In addition, Breathe’s products do not require any additional sensing hardware, operating using the temperature, current and voltage measurements available in standard systems.
We do, however, need samples of your battery pack to calibrate our product and enable the software for your battery.
Does this work with my microcontroller?
We are continuously adding to the list of microcontrollers that we validate with and currently work with microcontrollers with a range of capabilities. These include small microcontrollers for applications such as audio earbuds up to those used in battery management systems for large automotive battery packs.
Where do you test and qualify your battery software products?
All testing is performed in-house to your qualification standards.
We have a 7,500 sq. foot lab in east London which generates 4,800+ hours of data validation every day.
Why does this technology increase charge speed and safety?
We correlate safety with state-of-health.
We see evidence of lower state-of-health decreasing battery safety, for example, lowering the onset temperature for thermal runaway.
Since both of our products, Breathe Charge and Breathe Life, dynamically adjust charging in response to state-of-health, they actively avoid a damaging positive feedback loop.
Traditionally as the battery ages, charging becomes too aggressive for the state-of-health, which lowers state-of-health further, which in turn widens the gap further between the charging strategy and the state-of-health.
By breaking this positive feedback loop our products enhance both health and safety.
What industry sectors do you work in?
Breathe currently works with top tier OEMs and tier 1 battery system manufacturers, in the automotive and consumer electronics (smartphones, laptops, audio devices) industries.
What does Breathe’s licensing model look like?
Breathe's fee structure is simple and split into two parts.
Product setup and the proof of concept (PoC) requires a fixed fee which includes validation of charge control products on your battery.
Upon completion of PoC, we will provide you with a licensing agreement to give you access to Breathe's products.
Licensing fees consist of a fixed uptake fee and a volume linked royalty fee. Maintenance and support is always optionally available and is charged annually. 
What inputs do you need from us?
To get set-up with our products, we require you to supply us your system battery pack and the data sheet provided by your cell supplier.
We then parameterise our battery model architecture, PHI X2, by performing some light tests on the battery and we calibrate our software products (Breathe Charge or Breathe Life) to deliver the co-agreed performance for you.
What outputs will we get from the software?
Breathe Charge and Breathe Life will provide a real-time recommendation of the ideal charging current for your product. Our products additionally provide diagnostics outputs. For our largest customers where required we can support with custom wrappers and interfaces. 
Does your software satisfy your customer’s safety requirements?
Yes. We comply with our customer’s safety requirements and build our software according to a range of industry standards.
