The system, capable of predicting an EV battery’s remaining life with over 90% accuracy, can be integrated into a car-grade battery management system or utilized via a cloud-based platform.

Eatron Technologies, in collaboration with WMG at the University of Warwick, has made significant strides in the field of electric vehicle battery technology by developing a method to accurately predict the remaining useful life (RUL) of these batteries. This breakthrough, which is a result of their joint efforts, greatly enhances the performance, range, and safety of electric vehicles. The project, funded by the Faraday Institution under the VIPER initiative, merges WMG’s advanced electrochemical models with Eatron’s sophisticated cloud-based battery management system. This integration has yielded RUL estimates with an impressive accuracy rate of over 90%.

Over time, the performance and condition of batteries naturally decline, leading to potential cell failures if they are not adequately monitored. Traditional methods of estimating RUL, which are primarily based on voltage readings, often fail to identify complex failure scenarios. This can result in compromised safety and the unnecessary disposal of batteries that are still in good working condition.

This advancement in accurate RUL prediction is a game-changer. It ensures maximum battery performance and extends battery life, all while maintaining the highest safety standards. The technology is perfectly suited for use in automotive-grade battery management systems or on cloud platforms, making it particularly beneficial for fleet applications. Additionally, when a battery is repurposed, it is accompanied by a comprehensive ‘battery passport’. This feature eliminates the need for expensive testing procedures and expands the battery’s range of applications.

Dr. Umut Genc, the CEO of Eatron, has underscored the importance of this development. He notes that it has the potential to significantly improve the range and lifespan of electric vehicles. This innovation is particularly beneficial for the pre-owned electric vehicle market, providing reliable RUL estimates that can boost consumer confidence in the long-term performance of EV batteries.

Dhammika Widanage, Associate Professor at WMG, has expressed gratitude for the funding provided by the Faraday Institution, which has played a crucial role in accelerating this project. He acknowledges the growing demand for such innovative solutions, especially among automotive original equipment manufacturers (OEMs).

Finally, Professor Pam Thomas, CEO of the Faraday Institution, has emphasized the critical role of UK-based developments in the creation of efficient, fast-charging, and sustainable batteries. These advancements are essential for the rapid increase in electric vehicle usage and for achieving the ambitious net-zero targets. The collaboration between Eatron and WMG is a prime example of the impactful research and innovation fostered by the Faraday Battery Challenge.
