Unlocking fast-charge performance in high-energy EV batteries

Managing electrochemical margins to enable faster charging in long-range EVs

Fast charging and long range are now basic customer expectations. Higher energy density batteries make this harder by narrowing safety margins and limiting how fast cells can be charged using conventional BMS strategies.

This technical whitepaper explains how real-time, physics-based control of electrochemical margins enables faster charging from existing battery hardware while maintaining safety and lifetime.

What you’ll learn:

Why many high-energy EV batteries charge more slowly than they need to
Which electrochemical margins actually limit fast charging and cause lithium plating risk
Why lookup-table charging strategies lose performance as batteries age
How closed-loop, physics-based control adapts charging in real time to temperature, state of charge, and ageing
Validated results showing faster 10 to 80% charging and more range added in ten minutes without reducing durability on a vehicle in production……

Introducing Adaptive Charging

Automotive OEM engineers, battery and system engineers, BMS and control developers, platform architects, and R&D teams responsible for charging performance, battery health, and EV platform optimisation.

Designing EV Batteries for Both Long Range and Fast Charging

Battery behaviour is unpredictable, changing with chemistry, condition and age. Traditional testing is costly, slow, and limited. That is why Breathe introduces model distillation, a breakthrough approach that transforms high fidelity physics models into lightweight control ready models. Our distilled ECMs deliver accuracy comparable to traditional methods while cutting lab time and cost. They adapt seamlessly to aged cells and new designs and slot directly into existing control workflows. Discover how to accelerate battery design and control with simulation first.
