First Gen Chevy Volt Battery Pack
During the recent 2016 Chevrolet Volt ride and drive event in California, Larry Nitz, General Motors' vice president of electrification, commented on the durability of the battery cells in the original first-generation Chevy Volt.
According to Nitz, the cells have been nearly flawless. Nitz confirmed what we already know from real-world experiences, there's virtually no loss of range on Volts, even high-mileage ones.
But it's this comment from Nitz that really caught our attention:
“We’ve seen what I would call pharmaceutical levels of quality in cell production. Of the more than 20 million cells that have been produced for the first generation Chevy Volt, we’ve seen less than 2 problems per million cells produced.”
So, assuming ~20 million cells produced, there's been only ~40 problematic cells. That's extraordinary!
