Tesla Battery Maintenance Tips
Battery Discharge When Parked
While your Tesla is parked, the battery continues to charge the onboard electronics and discharges at a rate of about 1% per day. Your vehicle configuration, weather extremes, and settings will affect how long it lasts. You can control how quickly your vehicle discharges by making sure your car’s settings are optimized for battery efficiency.
Importance of Cabin Overheat Protection
Researchers from the University of California found that, during a simulated shopping trip, vehicles parked in the sun reached an average temperature of 116°F, dashboards reached 157°F, and steering wheels reached 127°F. “Within an hour.”
Cabin Overheat Protection is a safety feature Tesla offers to combat this problem. On a hot day, this feature ensures that your Tesla will remain below a certain temperature inside, even when you are not nearby. It is possible to set Cabin Overheat Protection to 90°F, 95°F, or 100°F. It is possible to reduce your vehicle’s energy consumption by selecting a higher temperature.
Sentry Mode and Energy Usage
When you’re not driving, some of your EV’s customized settings can have a significant impact on its battery consumption. Sentry Mode is an important setting.
By activating Sentry Mode, your vehicle’s cameras are always recording events taking place around it. Nevertheless, due to Sentry Mode’s increased energy consumption, some Tesla owners disable it at frequently visited places like home and work, while enabling it when parked in unfamiliar areas.
Extended Unplugged Period – The 1% Charge Level Rule
It is inevitable that you will occasionally have to leave your EV unplugged for an extended period of time as life is unpredictable. If you don’t plan ahead at the airport, you may find yourself in this situation. Keep your battery charged to avoid any unwanted surprises in such cases.
It is recommended that you follow Tesla’s 1% rule in these situations to ensure the battery has sufficient charge. As an example, an average battery can lose 14% of its charge over 14 days at a rate of approximately 1% per day. Don’t forget to plan ahead.
Low-Power Consumption Mode
When the battery is discharged to 0%, either unplugged or driven, its components can be damaged. The low-power consumption mode on Tesla vehicles protects against this. Your Tesla enters this mode when its charge level reaches approximately 0%. It is at this point that the battery stops supporting the onboard electronics and the auxiliary low-voltage battery.
By phone or through your app, contact Tesla Support if your Tesla enters low-power consumption mode.
