In her post on Forbes, auto writer Joann Muller says the idea that Chevy Volt batteries are unsafe is pure poppycock... balderdash... hooey... or as she puts it:
Hogwash. GM and its battery partner, LG Chem, have tortured that battery to death. They’ve abused it, mutilated it, jarred it, twisted it, and even punctured it with nails. There’s nothing wrong with the Volt or its battery that can’t be fixed with a couple of minor tweaks.
The minor tweaks are coming after a government safety test found that the batteries can catch fire seven days to several weeks after a crash. No fires were reported in real-world circumstances.
The company announced today that it will add parts to ensure the batteries will not catch fire.
Muller reports that the government has crashed a Volt with the new parts - no fire yet - but they'll give it another week to see if one starts up:
In a statement, NHTSA said it crashed a Volt retrofitted with GM’s newly designed steel reinforcement device in a side-pole impact test on December 22. The results of that crash test showed no intrusion into the vehicle’s battery compartment, and no coolant leakage was apparent. As a precaution, NHTSA has monitored the crashed vehicle since the test and will continue to do so for one more week. But the agency said the preliminary results of the crash test indicate that GM’s fix should solve the problem.
