#Chevy volt range degradation full

As the first generation of mass-produced EVs approaches a decade or more on the road, weвЂ™ll soon have far more data about how well they age. Overall, Geotab recommended keeping EVs charged between 20% to 80%, minimizing fast charging, and sticking to temperatures on the cooler side if possible as the ideal way to extend the capacity of your EV battery. As always, correlation is not causation: ItвЂ™s possible other factors associated with hotter climates (not just heat) may play a role in battery degradation. Tesla owners also mentioned that range is not the only factor: how fast it charges may change over time, particularly as carmakers introduced over-the-air software updates designed to protect batteries even if it negatively affects capacity and charging times.

None of the vehicles studied had reached that point, so more analysis will be needed to understand the full EV battery lifecycle. A slow decline for many years can be followed by a steeper drop.

Combined, the two factors led to faster battery degradation: about 10% of the original capacity after six years. Frequent fast-charging (direct current) also took a toll compared to slower Level 1 or 2 charging (alternating current at 120 and 240 volts).

Batteries lost their capacity faster in warm climates. Surprisingly, heavy use (charging many times per week) did not meaningfully accelerate EV battery degradation. All EV are less efficient in colder temps due to several factors. Cold weather is a temporary losss, not so much capacity as range which is an estimate based on recent driving efficiency. You can compare brands with GeotabвЂ™s tool here. Experienced EV owners define degradation as permanent capacity loss.

One Model X, after covering 330,000 miles, saw its original batteryвЂ™s range fall from 260 miles to 200 miles (23%)-for comparison, pooled data from Tesla owners shows batteries losing about 10% of their charge after 155,000 miles.Д«ut not all brands performed the same: The Nissan LeafвЂ™s passive air-cooled batteries were bested by TeslaвЂ™s liquid-cooled versions, suggesting thermal management is a key differentiator for carmakers. A Tesla rental service in Southern California, Tesloop, has driven its vehicles well beyond 300,000 miles, with no plans to remove them from service.
