Batteries in Electric Cars Examined After Chevy Volt Fire Regulators Examine Electric Car Batteries After Fire - NYTimes.com According to TFA, they didn't follow GM's procedure to disable the battery after a crash. Just goes to show though... with a new technology there will be road bumps and perceived safety is a big deal. I hope Tesla is way out in front of this. A 5-star rating won't help much with a reactionary press and a couple isolated incidents. From Tesla website: "In the event of a crash, the battery structure protects cells from impact and automatically disconnects the power supply". Anyone know if the Volt has such a safety feature?
