Electric vehicles have certainly become an increasing trend. Yet, many potential buyers question whether to switch from a traditional to an electric vehicle. Apart from price and range, the car battery lifespan is the main concern for each buyer of an EV.

Similar to the lithium-ion batteries on your laptop or phone, the battery life of the electric vehicle loses some of its capacity over time. The key issues are how to take care of and maximize the car battery lifespan, increase its capacity and avoid the battery degradation?

Maintain the Optimal Charging State

To extend your EV’s battery lifespan, it is highly recommendable to keep your vehicle charged between 20% and 80%. Even though these numbers may vary, lithium-ion batteries are the most stable and last longest at around 50% charge.

Don’t Fully Charge the Batteries to 100%

Fully charging lithium-ion batteries can reduce their usage. This fact is well-known to the manufacturers, so even when you believe you have charged your batteries to 100%, technology ensures that this number, in reality, is 90%.

But even with 10% left for preventing overcharge, the batteries are still eligible to damage.

In case you don’t need an extra battery for the day, it is always better to leave it up to 80% charged and this will ensure to maximize the car battery lifespan.

Additionally, before taking off for a drive you should always let the batteries cool off after a charge.

Avoid Deep Discharging

Frequently draining your battery has the same effects as overcharging. This can cause permanent damage to the cells and decrease the car battery lifespan.

Leaving the battery life at a low percentage for a longer period also contributes to battery life degradation.

Refrain From Fast Chargers

Nowadays it is inevitable to use a top-up in a hurry, boost your car battery lifespan to 80% in a short period and go on with your daily activities. However, you must avoid fast chargers as much as possible.

Each time you put the battery on a fast charger, a little bit of the battery lifespan is taken away.

Even though this may not seem significant at the moment, using a normal charge could benefit you in the long-run. More specifically, it will add a few years to your EV’s battery lifespan.

Stick to Cooler Temperatures

The lithium-ion batteries are sensitive to high temperatures. Even though electric vehicles are designed with a built-in thermal management system to regulate the temperature and cool the batteries off, sometimes this is just not enough.

Make sure to take additional preventive measures such as parking the vehicle in the shade, in a garage or a carport.

When compared to fossil fuels, lithium-ion batteries are way greener. These batteries also promote many sustainable actions. Yet, they are not classified as “environmentally friendly”.

So, maintaining the optimal car battery lifespan and avoiding battery degradation will not only save you money and protect you as an individual, but it will bring great benefits to the environment as a whole.
