New data showcasing the remarkable advancements in EV battery technology is now out from Generational.

The data shows battery health for EVs produced in 2023 is more than 10% higher on average than those manufactured in 2016 and 2017

Proprietary technology from the battery health certification firm has revealed that battery health for EVs produced in 2023 is more than 10% higher on average than those manufactured in 2016 and 2017, despite covering an equal distance over their lifetime.

In the vehicle set tested, EVs from 2016-2017 had an average battery health of 75.87% at 90,000 miles, with 2023 vehicles recording an average of 86%.

Even at far lower mileages, the differences in battery health – and therefore driving efficiency and real-world range – remain stark. At 50,000 miles, 2023 EVs recorded on average more than 5% higher battery health than 2016-2017 models. 2019-2020 vehicles achieved almost 5% higher than the 2016-2017 EVs at the same mileage.

Generational said the new data highlights the remarkable gains made in battery development, and the minimal relevance of mileage in the electric age.

The results also underline the urgent need for transparent, easy-to-understand information on battery health to be made universally available across the second-hand vehicle market – powering informed decision-making for all stakeholders from automotive dealers and drivers, to leasing companies and financiers.

Generational’s data forms part of its EV battery health database – developed over the past two years and continuously expanding as more vehicles are tested.

The assessments present results as a percentage compared to new, benchmarked against the manufacturer’s original data, and allowing easy comparison across vehicle generations.

Oliver Phillpott, CEO of Generational, said: “In the electric age, battery health provides crucial context to mileage when assessing a used EV’s condition. Our testing provides transparency into the actual performance you can expect.

“As with combustion-engine vehicles, used-EV customers want to be able to determine which vehicle will be the best for their needs; for some buyers, vehicles with moderately lower battery health may offer excellent value – they just need the right information to arrive at that conclusion. That’s what battery health certification provides, and what’s needed to create a healthy, sustainable market for used EVs.”

Generational’s compact device can be plugged into an EV’s OBD port – securely analysing the vehicle’s data to accurately determine its battery’s state of health, before it’s valued or acquired.
