Warranty and life of batteries of an EV

Electric vehicle batteries

Batteries are basically devices that store chemical energy that is converted into electricity. The modern battery was invented in 1800 by the Italian physicist Alessandro Volta. This amazing invention has enabled advanced devices such as laptops, smartphones, satellites and even electric vehicles to power much of the modern world.

Consumers are often concerned about battery life when considering the purchase of an electric vehicle (EV). The idea of ​​replacing the battery pack is especially daunting, given that the average cost ranges from Rs.3.70,000 to Rs.1.15,000 and does not take labor costs into account.

In this article, we will consider how the battery works and how it works optimally.

How long does an electric car battery last?

Electric vehicle batteries are designed to last a long time. However, electric vehicle batteries gradually begin to lose the amount of energy they can store over time. This phenomenon is known as “battery degradation” and can reduce energy capacity, range, performance, and overall efficiency.

Unfortunately, it’s not easy to predict battery deterioration. Not all brands offer the same level of performance, and each vehicle has a different way of driving, charging, and servicing. On the plus side, it’s not uncommon for modern EV batteries to last for more than a decade, and some go far beyond that before they need to be replaced. The average electric car owner will sell his car long before the battery has to be replaced.

It is important to note that in some scenario’s battery degradation is known to be exacerbated. If the EV battery is repeatedly driven near zero range and then periodically charged from low to full charge, if the EV battery is continuously charged at level 3, also known as DC Fast Charge (DCFC). As a result, some automakers are proposing to limit DCFC and not make it the primary source of charging.

Batteries do not work well, especially when the temperature is below 20 degrees Fahrenheit. It is very cold and using car heaters can temporarily reduce the range by up to 40%.  To maintain the best performance of the battery pack, it is recommended to charge the EV in the range of 60% to 80%, minimize fast charging and avoid extreme temperatures for a long time.
