Electric car news
Electric car owners often worry about battery longevity. However, a recent case study demonstrates their excellent durability, particularly for LFP (Lithium Iron Phosphate) technology.
Exceptional performance of Tesla LFP batteries
A 2022 Tesla Model 3 equipped with an LFP battery has just crossed the threshold 177,000 kilometers with remarkable results. Used intensively as a VTC vehicle in Texas, this Model 3 displays a degradation of only 5% of its initial capacity. Autonomy has gone from 437 to 415 kilometersa minimal drop considering the intensive use of the vehicle.
Advantages and specificities of LFP batteries
LFP batteries are distinguished from NMC (Nickel Manganese Cobalt) batteries by several essential characteristics:
- Production cost reduced by 30% compared to NMC batteries
- Possibility of recharging at 100% risk-free accelerated degradation
- Significantly longer lifespan
- Less environmental impact thanks to the absence of nickel and cobalt
Intensive use and fast charging
The owner subjected his vehicle to particularly demanding conditions of use. The car consumed 22 megawatt hours in DC fast charging and close to 8 megawatt hours in AC charging. Despite this intensive use, no major repairs were necessary, apart from the traditional replacement of tires and windshield washer fluid.
Comparison of battery technologies
| Features | Batteries LFP | Batteries NMC |
|---|---|---|
| Recommended charging | Up to 100% | Limited to 80% |
| Energy density | Weaker | Higher |
| Production cost | Lower | Higher |
| Sustainability | Excellent | Good |
Impact on the second-hand market
These encouraging results position Tesla Model 3s equipped with LFP batteries as a particularly attractive option on the second-hand market. The low degradation observed reassures about the durability of these vehicles, even after intensive use. Other owners report similar results, with damage to 2% after 32,000 kilometers and approximately 5% after 137,000 kilometers.
Paradoxically, Tesla ceased marketing the Model 3 LFP in the United States in October 2023, now favoring versions equipped with NMC batteries. This strategic decision does not detract from the demonstrated qualities of LFP technology, which remains a relevant option for buyers looking for reliability and durability.
