Used car dealer Kvdbil has investigated the electric car batteries of 1,300 electric cars and plug-in hybrids. The batteries are rated according to "State of Health", SoH, which measures the difference between the batteries' current condition compared to their original capacity. In the survey, eight out of ten car batteries received the highest rating, showing that over 90 percent of the capacity remains.
We have seen indications of this before, says Martin Reinholdsson and adds:
We were a bit surprised that there were so many that were this good.
Different models
Kvdbil does not list the car models that performed the worst. Martin Reinholdsson says that the car batteries that performed worse were mainly from cars that were significantly older and had been driven a very long way.
It is not really tied to a typical car or typical car manufacturer. It is more to the wear, that is our analysis of it.
At the same time, there are several factors that affect how well a car battery holds up.
Age, climate, driving style and charging habits. They play in as fairly large factors on the wear.
Take care of the battery
At the same time, there are several ways to preserve the durability of the battery. Among other things, it is important not to charge the car over 80 percent too often, not to expose it to extreme heat or cold and not to fast charge too often.
These things play in, and they are the ones you can influence. Then age and mileage come naturally, it is difficult to influence that.
Kvdbil rated the well-being of the batteries of a total of 723 electric cars and 643 plug-in hybrids.
