Why Is My EV Showing Incorrect Battery Percentage?
Your EV battery percentage seems wrong — too low, jumping around, or not matching how far the car actually drives. Here’s exactly what causes it and how to fix it.
Range can vary a lot between two identical trips, and the cause is not always the battery. This section covers the real factors behind range changes: temperature, drive mode, driving style, and how each one affects the number on the dashboard. Read why range differs between Sport and Eco mode to see how much of a swing is normal, and why an EV loses charge while parked if the range keeps dropping even when you are not driving. For overall battery condition, see battery health.
