Arguing for and against the accusation of EV battery drainage during inactivity.

EV battery drainage during inactivity can be a hot topic among people who own electric vehicles. Some drivers claim that their batteries drain quickly, even when the vehicle is not in use. On the other hand, other drivers say that they have had no such issues.

So, what’s the truth behind these claims? The effects of long-term inactivity can indeed cause some battery drainage. However, the amount of drainage varies, depending on various factors, including the age and capacity of the batteries, ambient temperature, and the duration of inactivity. To understand this better, think of a phone battery.

If you go out of town for a week, and don’t use your phone, the battery will still drain a bit, but not significantly. However, if you leave your phone behind for months, the battery will likely drain more. The same principle applies to EV batteries.

If not used for some time, they undergo a natural self-discharge process, where they lose charge gradually. Also, the ambient temperature has a profound impact on this process. In colder climates, the batteries tend to lose their charge more slowly, while in hotter climates, the opposite is likely to occur.

All said, there’s no denying that inactivity does have an impact on EV batteries. But this impact isn’t as significant as some drivers claim it to be.
