10 Expert Tips to Extend Your EV Battery Life

1. Maintain Charge Levels Between 20% - 80% (Optimal Range)

EV batteries (Lithium-ion) function much like human muscles; they perform best within a specific range. Maintaining a charge between 20-80% reduces chemical stress. Allowing the battery to hit 0% (Deep Discharge) can damage cells to the point where they may no longer hold a charge, while frequently charging to 100% creates high internal pressure and heat.

• Result: Significantly slows down battery degradation and extends the "Cycle Life" by several years.

2. Prioritize AC Charging and Avoid Frequent DC Fast Charging

DC Fast Charging delivers a massive amount of electricity in a short time, leading to significant heat buildup. Frequent use can degrade the battery's electrolyte faster. It is recommended to use AC (Home Charging) as your primary source, as it provides a much gentler current.

• Result: Maintains a high Battery SoH (State of Health) over the long term.

3. Always Park in the Shade or Well-Ventilated Areas

EV batteries have an ideal "Operating Temperature." Parking in direct, intense sunlight forces the Thermal Management System to work overtime even when the car is off, leading to unnecessary energy drain and heat stress.

• Result: Prevents battery swelling and premature degradation caused by heat accumulation.

4. Utilize Scheduled Charging

Leaving a car charged at 100% for many hours overnight puts the battery under high stress. By using the "Scheduled Charging" feature to reach your target (e.g., 80% or 100%) right before you plan to depart, you minimize the time the battery spends in a high-voltage state.

• Result: Reduces unwanted chemical reactions within the battery cells.

5. Practice Smooth Driving & Use Eco Mode

Frequent "Kick-down" acceleration forces the battery to discharge high current instantly, causing rapid heat spikes. Accelerating gradually ensures a stable flow of energy and protects the electrical components.

• Result: Increases driving range per charge and extends the lifespan of the electric motor.

6. Maximize Regenerative Braking

When you lift off the accelerator, the motor acts as a generator, sending energy back into the battery. Mastering this mode instead of relying solely on mechanical brakes converts kinetic energy into electricity rather than wasted heat.

• Result: Increases range by 10-15% and reduces wear on brake pads, lowering maintenance costs.

7. Maintain Optimal Tire Pressure (High Pressure Tires)

Due to the heavy weight of the battery pack, EVs require higher tire pressure than internal combustion cars (typically 36-42 PSI). Even slightly under-inflated tires increase rolling resistance, forcing the motor to work harder.

• Result: Improves energy efficiency by 3-5% and prevents uneven tire wear.

8. Use Pre-conditioning While Plugged In

Cooling or heating the cabin consumes a lot of energy. By activating the climate control while the car is still plugged into the Wallbox, the vehicle draws power from the grid rather than the battery.

• Result: Leaves you with a full battery and an optimized temperature when you begin your journey.

9. Keep Battery at 50% for Long-Term Storage

The battery's chemistry is most stable at half-capacity. Storing a car with a 100% charge causes stress, while storing it at 0% risks a "Deep Sleep" state that can cause permanent damage. 45-55% is the "sweet spot" for storage longer than one week.

• Result: Prevents permanent cell damage during periods of inactivity.

10. Regularly Update Software (Over-the-Air Updates)

Manufacturers frequently release updates for the Battery Management System (BMS) to fix bugs and improve efficiency based on global user data.

• Result: Ensures your vehicle operates "smarter" and stays equipped with the latest safety and efficiency protocols.

 3 Habits to Avoid to Prevent Rapid Battery Decay

• Charging to 100% Daily: Unless you are planning a long trip, 80% is sufficient for city driving and much healthier for the battery.

• Aggressive Driving on Low Battery: When the battery is below 20%, voltage drops. Aggressive acceleration during this state puts extreme strain on the cells.

• Charging in Direct Sunlight: Charging naturally generates heat; adding solar heat forces the cooling system to work unnecessarily hard.

Maintenance Checklist by Mileage

While EVs have no engine, certain components still require regular checks:

• Every 10,000 - 20,000 km: Tire rotation, balancing, and brake pad inspection (EVs are heavier, which can lead to faster tire wear).

• Every 40,000 km: Replace the cabin air filter and check brake fluid condition.

• Every 100,000 km: Inspect the Battery Coolant system and high-voltage wiring.

Myth Busting: "Can EVs Drive Through Floods?"

The Truth: EVs are designed with high-level water and dust protection (IP67 or higher), meaning the battery is hermetically sealed and can technically be submerged in 1 meter of water for 30 minutes. However, it is never recommended to drive through water deeper than the center of the wheels for extended periods to protect other electrical auxiliary systems.
