Pure BEV vs Range Extender: Chevy Volt Owner Weighs In
Ivan Jue from San Jose, CA comments, explaining why he prefers the Range Extender option.
A bit torn on this. Would love to go back to a BEV again. But having experienced battery degradation (20% in 2.5 years on our '11 Leaf), I can't go back to a pure BEV just yet.
All batteries will degrade. While the earlier Leaf batteries take it to the extreme, even a Model S battery will degrade over time and use (though at a much smaller rate--~1-2% a year). Tesla reps have already told me this multiple times.
The PHEV allows for larger buffers and TMS that would hopefully maximize longevity. One Volt owner ("sparkie") has already gone 230k (and counting) on his Volt (88k on battery) with little to no battery degradation. According to VoltStats (using Onstar) quite a few Volt owners are not far behind sparkie (again, no reports of battery degradation).
Yes I don't like having a range extender, as I easily use the battery range on my Volt on most days. But there are a few occasions when having the REx is a real blessing. Such as when the charging destination is occupied or not functional.
If I keep leasing, sure, I'd go back to a BEV. But since I put on too many miles and want the car to be useful for 10 years, I'll go with the range extender for now. The additional maintenance requirements on the Volt's ReX is very minimal--oil change every 2 years is really it.
