The lifespan of the battery is related to many factors. Temperature and charge/discharge cycles are the most important ones.
Try to keep you electric car’s battery cool, temperatures between 20º C and 25º C are recommended.
In the previous article I mentioned that white coloured cars are cooler than dark coloured cars. Have this in mind.
Avoid fast charging when not needed, specially when your car is already hot. Charging an electric car battery in 30 minutes is great, but it rises its temperature if it doesn’t have a TMS (thermal management system). If you have a Nissan Leaf, this is a no-no.
Completely charging and discharging your battery is a bad idea. If you don’t need the extra range, charge your electric car to 80 % and avoid to discharge it below 20 %. Batteries with their state-of-charge (SoC) in extremes (high or low) have an increase in internal resistance and temperature.
More charge/discharge cycles means more battery degradation. If you drive more efficiently you’ll reduce the charge/discharge cycles your battery have to do to drive the same distance.
Anticipating your stops minimizing the use of brakes, will increase your driving efficiency.
Smaller and aero wheels will also improve your car efficiency, specially at highway speed, where aerodynamic influences the energy consumption more important than weight. You can also make sure you have low rolling resistance tires with the correct air pressure.
