Is fully charging an electric car good?

In the dynamic world of electric mobility, efficient and optimal charging of electric cars is essential to extend the battery life and ensure consistent performance. One of the topics that often generates debate among electric vehicle owners is whether charging the car to 100% is beneficial or harmful for the battery. In this article, we will discuss fully charging an electric car and provide recommendations on best practices.

The Science Behind Full Charging

Electric cars are equipped with lithium-ion batteries, which have specific charging and discharging characteristics. These batteries have an operational range between a minimum and maximum charge percentage. Full charging, that is, charging the battery to 100%, can influence wear and degradation of the battery over time. Currently, we find state aids in addition to offers from car brands to buy affordable electric cars, so it is essential to thoroughly understand the differences with combustion cars.

Most manufacturers recommend not charging the battery to 100% on a constant basis. This is because lithium-ion cells can experience chemical and mechanical stress when fully charged, which can accelerate degradation. However, it is also important to note that battery technology has advanced significantly, and many electric vehicles come with sophisticated battery management systems that minimize these effects.

Recommendations for Optimal Charging

Keep Charge at Moderate Levels

Instead of charging your electric car to 100% every day, consider keeping it in a range between 20% and 80%. This helps reduce stress on the battery and prolongs its lifespan without significantly sacrificing range.

Full Charge on Special Occasions

If you plan to take a long trip or need maximum available range, charging to 100% occasionally will not cause significant damage to the battery. However, avoid doing this on a constant basis.

Use Scheduling Options

Many electric cars offer charging scheduling options, allowing you to set when you want the battery to be at 100%. At V2C, you can use our free app V2C Cloud to schedule your charges. This is especially useful for planning charging before a trip.

Avoid Charging at Low Temperatures

If you are charging in cold climates, avoid charging the battery to 100%, as low temperatures can increase stress on the battery and thus reduce its lifespan.

Keep the Battery Cool

Conversely, the same applies. Avoid exposing your car to high temperatures while it is connected to charging. A hot environment can accelerate battery degradation.

In conclusion, fully charging an electric car is a practice that should be approached with caution and knowledge. Although modern batteries are designed to withstand a certain degree of full charging, it is advisable to follow the manufacturer’s recommendations and opt for moderate charging on a daily basis. As leaders in the manufacturing of electric chargers, at V2C we recommend adopting a balanced approach that combines moderate charging with full charging on specific occasions when necessary.
