Eatron, a software company in Warwick, and Warwick Manufacturing Group (WMG) of University of Warwick have developed a new approach to evaluate an EV battery’s remaining useful life, improving performance, range and safety.
VIPER–Validated & Integrated Platform for battery Remaining Useful Life, funded by the Faraday Institution, uses WMG’s advanced electrochemical models and Eatron’s cloud battery management and integration expertise to provide RUL estimates that are more than 90% accurate. Eatron and WMG’s technology may be embedded in an automotive-grade battery management system (BMS) or deployed on a cloud platform, making it ideal for fleet applications. In addition, when an automotive battery is redeployed into its second life, it can be accompanied by an accurate picture of its health in the form of a battery passport that negates the need for expensive testing and increases the breadth of its operating window.
“Unlocking the hidden capacity of a battery has the potential to increase an EV’s usable range and extend its lifetime,” said Dr Umut Genc, CEO of Eatron. “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.”
