Tesla Model 3 owners with lithium iron phosphate (LFP) batteries are sharing their experiences and insights into maintaining optimal battery health. As electric vehicle (EV) enthusiasts seek to maximize their range retention, varying charging patterns, battery age, and other factors come into play. In this article, we delve into the feedback from Model 3 owners, exploring the impact of charging habits and the average degradation percentage of LFP batteries.
Understanding LFP Batteries: LFP batteries are known for their affordability and longer charge cycles compared to nickel-manganese-cobalt (NMC) counterparts. Tesla employs CATL’s LFP batteries for its standard Model 3 and Model Y globally. Despite being less energy-dense, LFP batteries have gained popularity due to their cost-effectiveness and ethical considerations, particularly the avoidance of conflict minerals.
Insights from Model 3 Owners: A Reddit thread became a platform for Model 3 LFP owners to discuss their experiences. While Tesla recommends fully charging to 100 percent at least once a week for optimal battery health, owners shared varying perspectives on charging habits and their impact on degradation.
Charging to 100 Percent Weekly:
Many owners reported minimal degradation (around two percent) even after charging to 100 percent weekly.
Battery age was identified as a more significant factor than the number of miles driven in the initial years.
Daily Charging to 100 Percent:
Some owners experienced slightly higher degradation, with one reporting a 2.2 percent reduction in range after 20,000 miles.
Despite this, positive feedback highlighted the overall performance and battery retention of the LFP battery.
Exceptions and Older Models:
Older models, such as a 2022 RWD LFP with 85,000 miles, showed higher degradation of nearly five percent in two years.
Some owners suggested that the battery management system (BMS) might contribute to inaccuracies in displayed range, with possible recalibration solutions.
Optimizing Battery Health: To ensure accurate range readings, owners suggested recalibrating the BMS by letting the range drop below 10 percent for an hour and then recharging to 100 percent. Additionally, Tessie, a data logging app, was mentioned as a tool for monitoring and optimizing battery health.
Tesla Model 3 LFP owners shared valuable insights into maintaining battery health and minimizing degradation. While individual experiences vary, common themes of battery age, charging habits, and occasional recalibration emerged. Whether you’re a seasoned EV enthusiast or a newcomer, these tips and experiences offer valuable takeaways for maximizing the longevity of your Model 3’s LFP battery. Stick to the basics, follow the manual, and enjoy the ride while ensuring your EV’s battery remains in optimal condition over the long haul.
