A new approach to estimating remaining EV battery life has been developed, not just to improve range and safety but also EV performance. CAR explains the details.

If the condition of your electric vehicle (EV) battery is keeping you up at night, there’s a new approach in the works to improve accuracy when estimating how much life an EV battery has left. According to those behind the project, not only could the new approach keep EV drivers safer but may also help to maximise the range and performance of their car.

The project, glamorously known as VIPER – Validated & Integrated Platform for battery Remaining useful life – is being carried out by a coalition between the tech outfit Eatron Technologies and the Warwick Manufacturing Group (WMG) of the University of Warwick.

With funding from the Faraday Institution, the two groups have brought the full might of their respective areas of expertise to the table.

By combining WMG’s command of advanced electrochemical models with Eatron’s understanding of cloud battery management and integration, VIPER has produced remaining useful life (RUL) estimates with an accuracy rating of over 90%.
