The battery is the heart of the electric car — and also the biggest source of questions for beginners. Contradictory advice circulates, some useful, others exaggerated.
Separating myth from truth helps adopt simple habits, without anxiety and, above all, without giving up safety.
Myth: any fast charging “kills” the battery
Fast charging is not a villain by itself. Wear exists, but it is gradual and anticipated in the vehicle’s design. The problem starts when it becomes the rule in unnecessary situations.
In practice, it makes sense: - Use fast charging on trips or when time is critical. - Prioritize slow charging in daily use, especially at home.
From a safety standpoint, it is worth checking that the charger is in good condition and following the car’s guidance during the session. Interrupting the charge when error messages appear is always the right choice.
Truth: frequent charge extremes accelerate wear
Driving all the time with the battery near 0% or keeping it constantly at 100% is not the ideal scenario. These extremes increase the chemical stress on the cells.
A simple and safe habit is to keep, whenever possible, the charge within intermediate ranges in everyday use. This does not require obsessive precision: it is about avoiding the habit, not eliminating exceptions.
Myth: leaving the car plugged in all night is dangerous
Modern electric cars have systems that automatically stop charging when the defined limit is reached. In proper installations, there is no additional risk from staying connected after charging is complete.
The concern here is different: - Outlets and cables in good condition. - Electrical installation compatible with the power used.
Electrical safety comes before any discussion about degradation.
Truth: temperature matters — a lot
Excessive heat is one of the factors that most impact battery lifespan. This applies both to use and to charging.
Good practices include: - Avoid recharging right after intense use on very hot days, when possible. - Prefer covered or shaded places for parking. - Do not ignore alerts from the thermal management system.
In addition to preserving the battery, these precautions reduce risks associated with overheating.
Myth: driving “harder” always causes more degradation
Acceleration itself is not the problem. What matters is a constant pattern of high demand, especially with the battery very full or very empty.
Predictable driving, making use of regenerative braking and avoiding unnecessary peaks, helps both efficiency and safety. It is not about driving slowly, but about driving consciously.
Truth: vehicle updates and alerts are not a detail
The vehicle’s software manages charging, temperature, and battery protection. Ignoring updates or dashboard messages can mean missing important improvements.
For those just starting out, the rule is simple: if an alert appears, stop and understand it before continuing the trip. This habit protects the battery and avoids risky situations.
What really helps day to day
Without radical measures, some behaviors make a difference over time: - Alternate between slow and fast charging according to real need. - Avoid charge extremes as a routine. - Respect thermal limits indicated by the car. - Prioritize safe electrical infrastructure.
Taking care of the battery does not need to become a constant worry. With correct information and attention to safety, using an electric vehicle becomes more relaxed — from the very first kilometer.
