- Eatron and WMG’s collaboration, Project VIPER, produces over 90% accurate EV battery RUL estimates.
- Integration of advanced models and cloud expertise enhances EV performance and safety.
- Faraday Institution-funded project aligns with the mission to develop cost-effective, efficient, and recyclable automotive batteries.
Developing accurate EV battery life estimates with Eatron Technologies, WMG, and the University of Warwick
Eatron Technologies and WMG, University of Warwick, have unveiled an innovative approach to precisely estimate the Remaining Useful Life (RUL) of electric vehicle (EV) batteries. Project VIPER (Validated & Integrated Platform for battery Remaining useful life) received crucial funding support from the Faraday Institution.
VIPER integrates WMG’s advanced electrochemical models with Eatron’s cloud battery management and integration expertise, delivering RUL estimates with a remarkable accuracy exceeding 90%. This development holds significant promise for unlocking enhanced EV performance, extending range, and elevating safety standards.
The traditional methods of RUL estimation often rely on simplistic voltage-based analytics, susceptible to overlooking complex failure conditions. Failure to closely monitor the natural degradation of batteries poses risks of cell failures with severe consequences. The Eatron-WMG solution seeks to mitigate these risks by providing precise predictions of a battery’s RUL.
This collaboration offers flexibility in deployment. The solution seamlessly integrates into an automotive-grade Battery Management System (BMS) or implements across a cloud-based platform. The latter is particularly appealing for fleet applications.
Dr Umut Genc, CEO of Eatron, commented:
“Unlocking the hidden capacity of a battery has the potential to increase an EV’s usable range and extend its lifetime. There are benefits for the used EV market, too; as a result of these highly accurate RUL estimates, buyers could have confidence in the condition of a vehicle’s battery and be reassured about its ability to perform for many years to come.”
An additional benefit arises when EV batteries enter their second life. The solution provides an accurate assessment of a battery’s health. This eliminates the need for costly testing and expanding its operating capabilities.
Dhammika Widanage, Associate Professor, WMG, University of Warwick, added:
“The funding from the Faraday Institution has allowed us to bring the project forward by at least a year, and with innovative approaches such as this now in high demand, particularly among automotive OEMs, we’re delighted to be a part of bringing this technology to the market.”
Professor Pam Thomas, CEO, Faraday Institution said:
“Our support for UK-based efforts to develop cost-effective batteries that are efficient, fast charging, and can be safely and sustainably recycled is crucial to achieving the rapid growth in EVs on our roads that will see us deliver on our net-zero targets. The Eatron/WMG collaboration is a great example of the research and innovation elements of the Faraday Battery Challenge working together to deliver impact.”
