British scientists: even the oldest electric cars retain 85% battery charge

The UK’s largest study of the condition of used electric vehicle batteries found that the average battery health among cars of all ages was 95%. Auto Express reports this.

Experts studied 8 thousand electric vehicles under 12 years old. It turned out that the average battery health (SoH) regardless of age is 95% – this is significantly higher than the 70% that manufacturers usually indicate in warranties as the threshold for battery replacement.

Even the oldest electric vehicles—those between 8 and 12 years old—had an average battery health of 85%. At the same time, 25% of the cars in this group showed a result of about 82%, and the most well-maintained specimens retained up to 90% of the original capacity.

One of the key findings of the study: mileage does not always determine the condition of the battery. The company noted that electric vehicles with a mileage of more than 160 thousand kilometers often retain 88-95% capacity, which calls into question traditional assessment methods based on age and mileage. It is also noted that a new car with higher mileage can preserve the battery better than an older model that has been driven less.

Earlier it was reported that Mercedes-Benz will present a short one based on the Geländewagen.
