Modern EV Batteries: Resilient and Reliable for the Long Haul
If you’re an electric vehicle (EV) owner, you might find yourself constantly fending off myths from EV detractors, one of the oldest being "you’ll need a new battery every 75,000 miles." As drivers of modern EVs, such as the Tesla Model 3, can attest, this persistent claim is far from the truth.
Evidence Proving Long-Lasting Battery Life
Contemporary data and user experiences reveal that EV batteries significantly outlast the supposed 75,000-mile worry. For instance, a 2018 Tesla Model 3 Performance owner has clocked an impressive 200,000 miles on the original battery pack in under six years, showcasing the durability of EV batteries.
EV Batteries Surpassing Warranty Expectations
Critics often cite isolated cases or early model failures. One example is the first-generation Nissan Leaf, known for its reliability issues due to a small battery pack and lack of thermal management. These early teething issues have since been addressed, especially with manufacturers like Tesla and General Motors, who adopted liquid-cooled lithium-ion batteries. Modern vehicles, such as the Tesla Model S and Chevrolet Volt, routinely achieve 200,000 miles while retaining over 75% of their battery range.
Understanding Battery Degradation
While the initial 75,000 miles might see the most significant range reduction, degradation slows substantially afterward. The Tesla Model 3 owner, after 200,000 miles, reports that his battery still accepts around 66 kWh, signifying only about an 11-12% degradation from its original 75 kWh capacity. However, varying factors like charging inefficiencies can affect these figures.
RecurrentAuto’s analysis gives another dimension, rating the Tesla’s current max range at 85% of its original range. Variables such as driving habits, climate, and location also play a role in the overall range and battery health. Comparing these assessments suggests an estimated 13% capacity loss, bringing the range of this Tesla Model 3 Performance to about 270 miles from the original 310 miles.
Maintenance and Longevity
This Tesla Model 3 owner has faced minimal issues, mainly early control arm noise and a supercharging hardware service after 100,000 miles due to heavy fast-charging use. Tire longevity has been between 40,000-50,000 miles, except in cases of damage, and the brake pads and fluid remain original. The air conditioning system might need servicing soon, although it still functions adequately.
The Road to 200,000 Miles and Beyond
The early generations of EVs like the 2011 Nissan Leaf, with smaller, poorly managed battery packs, would likely need a new battery by now. In contrast, well-maintained modern EVs are setting new benchmarks, reaching 200,000 miles with minimal range degradation.
