My Chevy Volt May Outlive Me
Before taking possession of my 2013 Chevy Volt, the least of my worries was the lifespan of the battery.
The Volt battery has an active liquid cooling system. Chevy Volt does not use the full capacity of the battery which is another reason the battery will easily outlast the warranty. The battery warranty is 8 years/100,000 miles.
If the Volt battery has less than 70% of it's original capacity before the end of the warranty, it will be replaced. The worst thing that can happen to a Volt owner is having 71% battery capacity at 8 years/100,000 miles, which equates to 27 miles of all electric range (AER). This is more AER than a brand new Ford Fusion/C-Max Energi and more than two times the AER of brand new Prius plug in.
When the battery capacity is almost completely gone, I could choose to just drive it as if it were a brand new Prius plug in or I could choose to replace the battery. By that time, I could probably get a battery with more capacity for less money than batteries cost today.
The icing on the cake is this: If I'm like the average Volt driver, who only uses the gasoline engine for one-third of miles driven, the effective miles on the gasoline engine will be roughly 33K miles when it's time to replace the battery. When the battery is replaced with a larger capacity pack, I will use the gasoline engine even less.
