EV OTA Updates: What They Do and How to Install
Your EV shows an update is ready, or you wonder what these over-the-air updates actually change.
What causes it
EVs update software wirelessly like phones - fixing bugs, adding features and improving range/charging.
What OTA updates change
- Charging curve improvements - faster or more consistent fast charging.
- Range and efficiency tweaks - better thermal management and consumption.
- Bug fixes - infotainment, apps, driving aids.
- New features - music apps, driver assists, UI changes.
How to install
- Connect to Wi-Fi at home or a reliable hotspot for large updates.
- Schedule the update - most cars let you pick a time; many require the car parked.
- Keep the battery above ~20% - updates shouldn't run on a low battery.
- Some updates need a service visit - the app/car will tell you.
Good practice
Install updates within a week. They regularly fix real bugs - delaying them means living with known issues.
