NHTSA investigates the electric vehicle segment for fire risks
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.
