Eatron Technologies from the UK and WMG, University of Warwick, have developed an innovative system that can provide an accurate estimation of the residual battery life in an electric vehicle.
The process combines WMG’s electrochemical models with cloud management capabilities and Eatron’s battery integration. Independently validated and integrated, the VIPER (Battery Remaining Useful Life Estimation Platform) system was developed with financial support from the Faraday Institution.
According to project information, the precision of battery life estimates exceeds 90%.
Traditional battery life estimations are based on basic voltage analysis, which does not take into account complex damage conditions. Other systems are also overly cautious, resulting in a healthy battery being deemed unusable.
Precise prediction of the remaining useful battery life allows for maximum performance and durability, without compromising safety.
The solution developed by Eatron and WMG can be integrated with battery management systems or deployed in the cloud. The latter option is particularly useful for fleet management.
Additionally, when the battery is reused in other applications, accurate information about its health can be provided – a battery passport.
“Unlocking hidden battery capacity has the potential to increase the effective range of an electric vehicle and extend its lifespan,” said Dr. Umut Genc, CEO of Eatron. “There are also benefits for the used electric vehicle market, as potential buyers can be confident about the battery’s condition and its ability to function for many years.”
