What is a manufacturer to do about electric car batteries susceptibility to heat? As it turns out, the answer depends on what the warranty says, not so much on what the owner’s manual warns you not to do, Finley writes.
Before the Chevy Volt (a plug-in hybrid) went on sale, Volt Chief Engineer Andrew Farah openly acknowledged that the extreme temperatures found in the Southwest have the potential to permanently reduce the battery pack’s capacity to store energy:
“The Volt may not be right for everyone. If you live in the Southwest, depending on how you use your car, the Volt might not be right for you.”
So what is a manufacturer to do if a given customer’s driving habits consistently exposes his or her battery pack to excessively high temperatures in a place like Tucson, or charges it five times a day, or maybe applies a blowtorch to it? As it turns out, the answer depends on what the warranty says, not so much on what the owner’s manual warns you not to do.
