what is the maximum mileage?

Much more reliable than the thermal car, due to the simplicity of its engine, the electric car depends however on its batteries dictating its lifespan. What is its maximum mileage?

If we seek to answer this question, we must refer to the main part of the car: the battery. Why ? This has a lifespan limited by the number of recharge cycles.

The maximum mileage depends on the battery

Each type of lithium ion battery has its own duration. This varies between 1,000 and 1,500 charge cycles to maintain a satisfactory capacity, i.e. 80% in general. And the larger the battery, the lower the charging frequency.

To simplify, take an average distance traveled of 250 km and 1,000 charges for a BMW i3. You obtain at least 250,000 kilometers. Not bad, knowing that the average mileage does not exceed 200,000 km on a thermal car.

In the extreme case, what can we expect from a car type Volkswagen ID.3 a with a 77 kWh engine? With 1,500 charges and a range of 500 kilometers, the maximum mileage of the electric car climbs to 750,000 kilometers, in theory.

Tesla, reference in the field

In practice, we can cite Tesla having published precise statistics. According to its 2019 environmental report, the battery ofa Model S retains 90% of its capacity after 321,000 km. The American manufacturer even claims to exceed one million miles (1.6 million km) or even more than 3 million on the new “4680” batteries.

For example, the Model S range is 305km to 840km, with a single charge according to the American manufacturer. A German driver even succeeded in October 2020 to exceed the million kilometres!

A feat that deserves congratulations of Tesla CEO Elon Musk. The American firm continues to work on batteries still more reliable and less expensive for future models.

How to increase battery life?

To increase the endurance of the batteries and thus the maximum mileage of an electric car, it is necessary to preserve its battery via two methods.

The first is to don’t go to extremes of the battery gauge. It is highly inadvisable to go under 10%, and to charge beyond 90%, this increases the voltage in the battery. The second wants to use slow charging, at home for example, and reserve fast top-ups for when needed (long motorway journeys for example).

Note that these two points apply to all lithium-ion batteries, i.e. those of your smartphones or your laptop for example!
