This is the first post of my new blog about attempting to use my new Tesla Model Y to travel, camp, and continue to work on the road. I plan to backfill a lot of my previous research into a few new posts to help other who are thinking of buying a Tesla, or a new car in general. My first major questions were answered by the owners manual.
About the Battery
MODEL Y OWNER’S MANUAL
Model Y has one of the most sophisticated battery systems in the world. The most important way to preserve the Battery is to LEAVE YOUR VEHICLE PLUGGED IN when you are not using it. This is particularly important if you are not planning to drive Model Y for several weeks. When plugged in, Model Y wakes up when needed to automatically maintain a charge level that maximizes the lifetime of the Battery.
NOTE: When left idle and unplugged, your vehicle periodically uses energy from the Battery for system tests and recharging the 12V battery when necessary.
There is no advantage to waiting until the Battery’s level is low before charging. In fact, the Battery performs best when charged regularly.
NOTE: If you allow the Battery to discharge to 0%, other components may become damaged or require replacement (for example, the 12V battery). In these cases, you are responsible for repair and/or transporting expenses. Discharge-related expenses are not covered by the warranty or under the Roadside Assistance policy.
The peak charging rate of the Battery may decrease slightly after a large number of DC Fast Charging sessions, such as those at Superchargers. To ensure maximum driving range and Battery safety, the Battery charge rate is decreased when the Battery is too cold, when the Battery’s charge is nearly full, and when the Battery conditions change with usage and age. These changes in the condition of the Battery are driven by battery physics and may increase the total Supercharging duration by a few minutes over time.
