In cold weather, some of the stored energy in the battery may not be available on your drive because the battery is too cold. Tesla adds a snowflake icon next to the range indicator to show it might be impacted. Typically, it will cover around 10-20 percent fewer kilometres in cold weather versus beach weather.
To keep good battery health and range during cold times, don’t let the battery get too low — try to make sure you always have a 30 percent charge or so. If you want to power up in subzero temperatures, the car may need that reserve to warm the battery enough to start the process. Precondition the vehicle, for example, warm the interior, we let you do that via the Beast app.
