Is this level of battery degradation normal for VW MEB cars (ID.4, Enyaq, Q4)?
I'm considering buying a used EV based on the VW MEB platform. I've been browsing local listings, filtering for cars made in 2022 or later with 280+ hp, a 70+ kWh battery, and an official battery certificate.
Surprisingly, all the cars listed show noticeable degradation. I tracked the data for the first 12 cars I found: the average State of Health (SoH) is just 92.5% at an average mileage of 44,531 km (27,670 miles). One car even lost more than 10% of its capacity in just 43k km.
| Mileage (km) | SoH |
| 36,500 | 92.0% |
| 60,604 | 90.0% |
| 46,213 | 92.0% |
| 66,352 | 90.4% |
| 46,350 | 94.5% |
| 42,900 | 94.0% |
| 54,150 | 94.6% |
| 28,300 | 92.0% |
| 39,354 | 92.0% |
| 41,000 | 95.0% |
| 29,953 | 94.6% |
| 42,700 | 89.0% |
The table is for a Skoda Enyaq, but I also checked the VW ID.4 and Audi Q4 e-tron - all three models seem to show the same trend.
Is this expected capacity loss for MEB vehicles? It really bothers me because if you extrapolate this curve linearly, the battery is losing roughly 1.7% of its capacity every 10,000 km (or 2.7% every 10,000 miles).
