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.

Frequently Asked Questions

  • No. The approach is software-based and is designed to unlock more fast-charge performance from existing cell, pack, and thermal hardware.

  • Lookup tables predefine charging current based on surface measurements and cannot adapt precisely to ageing or real-world conditions. This approach estimates internal electrochemical states in real time and controls directly to safety margins.

  • No. Charging current is regulated to maintain the same electrochemical safety margins used in conservative strategies, protecting durability and reliability throughout battery life.

  • Yes. The approach has been validated at cell and vehicle level and is deployed in production on a high-energy EV platform across real-world temperatures and states of charge.
