NHTSA investigates the electric vehicle segment for fire risks

The National Highway Traffic Safety Administration has opened an investigation that is slated to spend the next three years investigating whether modern electric vehicles with lithium ion batteries pose a significant fire risk to consumers from overcharging.

This investigation has been launched by the NHTSA out of a concern for the future safety of consumers and not due to a fire in any electric vehicles. Many vehicles currently featuring electric propulsion or hybrid drive systems are powered by nickel hydride but the NHTSA expects that 70% of these alternative-power vehicles will feature lithium ion batteries in the next 10 years. For instance, Ford Motor Company plans to shift to lithium ion batteries in their entire electric and hybrid fleet within the next two years. This investigation was spurred by the fact that Dell recalled a large group of laptops with similar battery technology when it was found that overcharging could cause overheating and increase fire risks.

Actually I've never thought about this issue before but it makes sense. I HAVE used rechargeable batteries before and they ALWAYS get hot when I'm done; I don't think I'm even overcharging them, just charging normally but they get really hot when done. I can't even imagine charging a battery that can power a car. Sure they are spending a ton of money for the research but it's necessary to ensure the safety of drivers.
Getting hot is a serious misconception for many at NHTSA, one Alabama man made his pick-up truck energy efficient with a wood burner installation so how hot is hot to NHTSA over a sealed battery issue seems to be hot under the collar hot?

Bolton http://blog.al.com/spotnews/2011/09/springville_alabama_inventor_b.html Mr. Wayne Keith of Springville, Alabama drove a total of 7,388 miles to Las Vegas Bonneville Salt Flats a 2,100-mile drive, set a class world-record in his firewood-powered truck. He went 71.18 mph to break the previous record by more than 24 mph. His improved process emits zero emissions from the combustion closed system. What if this idea were used on a large scale to run internal combustion engines for electricity production at your home. No more gas pipeline threat, no more power company billings to erect poles to get their power to your location.
