| How To Keep Tesla Battery Healthy |
Sub-heading: The 80% Rule for Daily Driving
For everyday use, aim to keep your Tesla's charge level between 20% and 80-90%. Lithium-ion batteries, like those in your Tesla, experience less stress when they're not consistently charged to 100% or drained to 0%. Think of it like this: your battery is happiest living in the middle.
Why 80-90%? Charging beyond 80% slows down significantly, and the last few percentage points put more strain on the battery cells. For most daily commutes, 80% provides ample range. Tesla even recommends setting your daily charge limit to around 80-90%.
How to set it: You can easily set your charge limit using your Tesla's touchscreen or the Tesla app. Just drag the charging limit slider to your desired level.
Sub-heading: When 100% is Okay (and When It's Not)
Long Trips Only: Only charge to 100% when you absolutely need the full range for a long journey. The key is to drive shortly after charging to 100%, rather than letting it sit at full charge for extended periods. This minimizes the stress on the battery cells.
Avoid Deep Discharges: Conversely, try to avoid letting your battery consistently drop below 20%. Constantly operating at very low charge levels can also accelerate degradation.
Sub-heading: Embrace Regular Charging and Plugging In
Plug In Whenever Possible: Tesla itself recommends leaving your vehicle plugged in when you're not using it. This is especially important if you're not planning to drive for several weeks. When idle and unplugged, your Tesla still uses energy for system tests and to maintain the low voltage battery.
No Advantage to Waiting: There's no benefit to waiting until your battery is nearly empty before charging. In fact, the battery performs best when charged regularly.
Sub-heading: Supercharging: Use It Wisely
Convenience vs. Longevity: Supercharging is fantastic for road trips due to its speed, but it also puts significant strain on your battery. Frequent Supercharging can accelerate battery degradation.
Primary Charging Method: Avoid using Supercharging as your primary charging method. Rely more on slower charging options like a Wall Connector at home or public Level 2 chargers for daily top-ups.
Preconditioning: If you do need to Supercharge, use your Tesla's navigation to route to the Supercharger. This allows the vehicle to precondition the battery, bringing it to an optimal temperature for faster and more efficient charging, which also helps reduce stress.
Step 2: Mind the Temperature Extremes ️
Temperature is a silent but significant factor in battery degradation. Lithium-ion batteries are sensitive to both excessive heat and extreme cold.
Tip: Be mindful — one idea at a time.
Sub-heading: Hot Weather Strategies
Seek Shade: Whenever possible, park your Tesla in shaded areas, especially during hot weather. This helps keep the battery cooler and reduces the energy your car needs to expend on thermal management.
Garage Parking: If you have a garage, use it! It provides a more stable temperature environment for your battery.
Preconditioning while Plugged In: In hot climates, precondition your cabin and battery while your car is plugged in. This brings the vehicle to a comfortable temperature using grid power, rather than draining the battery once you start driving.
Avoid Charging in Excessive Heat: High temperatures can strengthen electric currents within the battery, which can erode lithium and affect charging efficiency.
Sub-heading: Cold Weather Strategies
Keep it Plugged In: In cold climates, keeping your Tesla plugged in is even more crucial. This allows the car to use external power to keep the battery warm, preventing capacity loss and improving efficiency.
Preconditioning: Just like in hot weather, precondition your battery and cabin while plugged in before driving in cold conditions. This is essential for optimal performance and range.
Seat Heaters over Cabin Heat: Using seat heaters is generally more energy-efficient than heating the entire cabin, especially for shorter trips.
Step 3: Drive Smart, Drive Efficiently
Your driving style directly impacts your battery's workload and, consequently, its health.
Sub-heading: Embrace Regenerative Braking
Standard Mode: Set your regenerative braking to "Standard" mode. This allows your Tesla to capture and store more energy back into the battery whenever you lift your foot off the accelerator, extending your range and reducing wear on your physical brakes.
Smooth Deceleration: Practice modulating the accelerator pedal to maximize regenerative braking and avoid abrupt braking.
Sub-heading: Moderate Acceleration and Speed
Smooth is Key: Avoid frequent rapid acceleration and hard braking. These aggressive driving habits demand more energy from the battery, generate more heat, and can accelerate wear and tear on the cells.
Maintain Moderate Speeds: Consistently driving at very high speeds increases energy consumption and can reduce battery life. Sticking to moderate speeds is more energy-efficient and kinder to your battery.
Use Chill Mode: Consider engaging "Chill Mode" for smoother acceleration and better energy conservation.
Step 4: Leverage Tesla's Smart Features and Maintenance
Tesla vehicles come equipped with advanced features designed to help you manage battery health.
QuickTip: Read step by step, not all at once.
Sub-heading: Utilize Scheduled Departure and Charging
Optimize Charging Times: Use the "Scheduled Departure" feature in your Tesla to set a time when you want your vehicle to be ready to drive. This allows the car to automatically complete charging and precondition the battery and cabin shortly before you leave, minimizing the time the battery spends at a high state of charge and optimizing efficiency.
Off-Peak Charging: If your electricity rates vary, schedule charging to align with off-peak hours to save money and potentially reduce grid strain.
Sub-heading: Keep Software Up-to-Date
Regular Updates: Tesla frequently releases over-the-air software updates. These updates often include optimizations and improvements for battery management. Ensure your Tesla's software is always up-to-date by regularly checking for and installing updates.
Wi-Fi Connection: For the fastest and most reliable delivery of software updates, keep your Tesla connected to Wi-Fi whenever possible.
Sub-heading: Monitor "Vampire Drain"
Energy Saving Mode: "Vampire drain" refers to the gradual battery discharge when the vehicle is parked and not in use. This can be due to features like Sentry Mode, Summon Standby, or maintaining connectivity.
Disable Unnecessary Features: To minimize vampire drain, consider enabling Tesla's "Energy Saving" mode when the vehicle is parked for an extended period, and disable features like Sentry Mode if not needed.
Step 5: General Vehicle Maintenance
While not directly about the battery, overall vehicle maintenance contributes to efficient operation, which indirectly benefits battery longevity.
Sub-heading: Maintain Proper Tire Pressure
Optimal Efficiency: Proper tire pressure is crucial for maximizing driving range and efficiency. Underinflated tires increase rolling resistance, forcing the battery to work harder.
Regular Checks: Regularly check and maintain the recommended tire pressure specified by Tesla for your model.
Sub-heading: Remove Unnecessary Weight
Lighten Your Load: Carrying excessive weight requires more energy from the battery. Remove any unnecessary cargo to improve efficiency.
Aero Covers and Accessories: If your Tesla has aero covers, keep them installed to reduce wind resistance. Be mindful that aftermarket accessories like roof racks can also increase energy consumption.
