When we think of an electric car, we directly relate it to its battery and everything that involves charging the vehicle so that we don’t get stuck. It is true that with the passage of time this technology has evolved very favorably over time, doing so because they last longer and offer higher levels of autonomy . However; It is important to know that we must recharge them from time to time, even if we use it…
The battery of your electric car also changes
With everything, and as we have been observing during all this time in which they have been presenting themselves to stay on our roads, the batteries of the electric car are responsible for all the gear working perfectly and for us to travel kilometers and kilometers without contaminating not waste fuel.
However, few drivers know their battery thoroughly. Yes, we know that these lead the much-needed transition towards mobility that does not use fossil fuels , something that is reflected in the growth in annual sales of this type of vehicle, which are a solution to make roads and cities less polluting. .
But it is important to consider that everything is taken care of in detail, especially when charging this type of electrified car. One of these aspects is well deepened with what is the moment of its recharge. And if; This means that we have to make some modifications in our way of driving, also for the moment in which we are not using the vehicle. This is due to the self-discharge of your batteries.
Cars lose power and affect the system
To find out how long a car battery lasts, we can get the following idea: if we empty and refill it every day, it would last more than eight years .
Of course, this is not typical, as it is recommended that electric car batteries never go completely dead (just as no one would let their internal combustion car run out of fuel), so the cycles of load increase. On the other hand, we find the aforementioned self-discharge, which can cause irreversible damage to the system itself.
We are talking about damage that is a consequence of the gradual drop in voltage in the battery cells , one of the biggest challenges faced by the manufacturers of this component, given that the electronics of new cars are increasingly sophisticated and require high doses of energy.
It is then that a molecule is created that is what causes, even if they are at rest, like the electric car when it is not being used and is not even turned on, they lose energy that should be stored in the battery. This also means that this phenomenon has an important impact on the degradation of battery cells.
What we have to consider
Towards this, we can expect an electric car to lose around 3-5% battery charge every week. It may seem very little… In fact, at that rate, a fully charged battery of an electric car that remains parked would take two years to approach the area where it could begin to deteriorate .
But it may also be the case that, either because it is an older car or because its batteries already have enough use and recharge cycles behind them , this effect could progress more quickly.
In the same way, there are circumstances that can accelerate this discharge, thus reducing the time we have to visit our electrician again before the battery begins to be damaged. Among them is the weather, especially the heat that deteriorates the chemistry of the cells. This is why it is not recommended to leave an electric car parked at a high temperature because the battery will suffer a lot and it will self-discharge a little faster.
