Is Fast Charging Bad For My EV Battery?

With increasing adoption of electric vehicles in India, new EV owners are likely to wonder if fast charging their vehicle is bad for the battery. Fast charging technology offers convenience, enabling drivers to quickly recharge their vehicles at charging stations. However, concerns about battery longevity and performance arise, prompting a closer look at this crucial aspect of EV ownership. This is because there are several myths and misconceptions related to EV batteries and their ageing.

As the name suggests, fast charging works by delivering high power to the EV battery, which significantly reduces the charging time compared to standard charging methods. While the technology is beneficial for users who need to charge quickly, it can generate

more heat within the battery. Excessive heat is one of the primary factors that can degrade battery health over time. However, most electric vehicle battery packs are built with thermal management systems that are capable of maintaining the EV battery temperature and protecting it against any major heat-associated degradation. Unlike a smartphone, an EV battery is a lot more resistant to any degradation throughout different types of charge cycles.

Still, experts suggest that the use of fast chargers should be balanced with regular charging practices. For instance, while occasional fast charging is acceptable, regular use can potentially accelerate battery wear over the course of years. In the context of EV charging tips, users should also consider the state of charge (SoC) when using fast chargers. Experts recommend avoiding charging to a high SoC frequently, particularly if it consistently reaches 100% charge. Maintaining the battery between 20% and 80% charge can promote better health over a prolonged time. Hence, switching to a standard charger after the EV reaches 80 percent on a fast charger can help.

While fast charging is not inherently bad for EV batteries, its use should be managed wisely. Balancing fast and regular charging, monitoring battery health, and understanding the implications of charging practices are crucial for optimal EV maintenance. By following these guidelines, EV owners can enjoy the convenience of fast charging without compromising battery longevity. Most importantly, the life and degradation of an EV battery cannot be compared to that of our everyday devices, such as smartphones. Where battery degradation can become noticeable in small devices over a few years, an EV battery is unlikely to display any compromise in performance that quickly.
