I just got a Volt. I'm curious to know how well the batteries are holding up on older Volts? Have you seen a significant decrease in range at 2 years, 3, 4?
There is so much buffer built into the programming, leaving some 6kw untapped even if there is capacity fall off from the owners point of view we'd likely never see it because you cannot fully charge nor discharge the Volts traction battery. Capacity loss is much more an issue in BEV's that utilize the battery capacity much more aggressively.I just got a Volt. I'm curious to know how well the batteries are holding up on older Volts?

Yes that's basically correct. The driver doesn't necessarily notice any performance change when the degradation is low enough to get buried in the unused capacity. I think it was a good engineering decision.Look, my car is only six months old, but respectfully I believe the question misses the mark slightly: the battery is a little over 18 kWh, but only 14 of that is usable on a daily basis. The packs are thermally controlled to ensure longevity, but even if they do degrade over time, such that say the total capacity of the battery was only 17 or even 16 or 15 kWh, you still get your 14 kWh for your 53 miles... Do I have that right, fam?
All that said, now that the weather's warmed up, after my 20+ mile commute in to work today, my remaining range was: 53 miles.
Enjoy that new Volt!!!
This is probably the biggest misconception that most people have about electric cars. Everyone gripes about rechargeable batteries in consumer equipment and so it's quite natural to project those same misgivings onto the batteries in electric vehicles. But the EV industry has designed their batteries, charging and power control systems to really baby the batteries so that they'll hold up far, far longer than your typical camera or laptop battery, and do so without loosing very much capacity. They have to do that because they need to offer long battery warranties to allay those negative vibes that the public has.Thanks, that's comforting news, it's also surprising given the experience of cell phones.
