The duration of the electric car batteries reported by the manufacturers also reaches 8-10 years, but what can you do to ensure maximum performance over time?
Let’s find out together.
Electric car batteries today
The current (and future) diffusion of electric vehicles will lead them to be very widespread even in a few years: but batteries? If it is true that a Tesla (for example) would be designed to grind even half a million km, the same is not true for its batteries.
In fact, the duration of the accumulators is actually an aspect still shrouded in mystery , and this doubt partly curbs the enthusiasm of the buyers.
Currently, the technologies being developed to optimize the characteristics of automotive batteries aim to reduce their weight, while improving their energy efficiency (and therefore autonomy): moreover, the increase (or at least the guarantee) of the durability of these devices.
The 5 tricks for the electric car battery
What we know for sure is that current lithium batteries are subject to deterioration, both due to the passing of time and the continuous charging cycles.
Here are the 5 tips to preserve (and extend) the life of automotive batteries :
1ST TIP: RECHARGE THE BATTERY WITHOUT EVER REACHING ZERO
Lithium batteries do not react well to continuous depletion of the charge so connect them to the charger when they are at about 40/50% .
The more you lower the starting point of the recharge percentage (for example by connecting it when it is at 30% of remaining charge), the more you will increase the number of possible recharges.
A note: keep in mind that part of this work is already done by the charging systems integrated by the manufacturers, and by the electronic control units, so what you read on the display is not the real state of the battery: you see 99%, but internally it is possible that the recharge is “calibrated” to 90% real to help you preserve the battery charge.
2ND TIP: ALWAYS CHARGE THE BATTERY WITH THE RIGHT VOLTAGE
The correct voltage is about 3V (or a little more): the batteries can, however, also recharge at 4.20V (at full capacity) to increase the absolute total of possible recharging cycles. Never use voltages higher than 4.15V (or lower than 3V), in order not to damage the cells.
3RD ADVICE: DO NOT DRIVE IN AN “AGGRESSIVE” OR ERRATIC WAY
Driving correctly will allow you to avoid fines and make your electric car battery last longer
4TH TIP: REFILL LITTLE AND OFTEN
Do not recharge the battery to 100%, unless you have to make a long journey: it is better to preserve the accumulator by charging it only “the right”.
5TH TIP: BEWARE OF HIGH TEMPERATURES
Try (as far as possible) to avoid exposure to high temperatures , as well as the use of high voltage charging points (such as “fast” charging stations)
To date, these are the right precautions that we advise you to keep in mind and put into practice to preserve your new electric car to the maximum.
