Why do EV batteries need to be charged up to 80 percent?

Owners of electric cars usually wonder how they can extend the life and battery life of their four-wheeler, and one of the most efficient ways is to charge the battery up to 80 percent.

Lithium-ion batteries do not tolerate extremes, so it was extreme heat and low temperatures, whether it is extreme cycles of charging and discharging.

Frequent charging to 100 percent and driving to an almost empty battery will reduce the amount of electricity the battery can store over time, writes Wind Works.

That is why most car companies advise that the batteries of electric vehicles be charged to 80 or 85 percent, but never to 100 percent. This also explains why the manufacturers, when stating the characteristics of the vehicle, take what is needed to charge the battery from 10 to 80 percent during charging.

Also, drivers of battery-powered cars should know that even an extreme discharge of the battery to less than 5 percent accelerates its degradation, especially if we allow the battery to be empty for days or even weeks.

Over time, lithium-ion batteries certainly lose their efficiency, but with these tips, it is possible to drive electric cars for up to 20 years, before the need to replace the battery arises.

In addition, another reason Wind Works cites for charging the battery to 80 percent is consideration for other electric car drivers who are also waiting for a public charger.
