Safety Advances in Electric Cars
According to NHTSA, the Tesla Model S, which protects its battery array with an additional shielding of an external aluminum plate and has a layer of fire protection between the batteries and the passenger compartment, received the highest possible safety ratings in crash tests.
Other electric vehicle manufacturers’ models scored similarly in regard to passenger safety, but not all had the additional levels of fire safety that are standard with the Tesla Model S. However, the evolution and development of fire safety in electric vehicles is moving at a rapid rate. Volvo, a competitor that is well-known for its safety ranking, is designing its latest electric model with the battery array in a location farther from the passenger compartment, while Toyota and Sakti3, a company owned by Dyson Technologies, are pioneering new solid-state batteries that don’t rely on flammable electrolytes to power electric cars.
In all, NHTSA concluded that the likelihood of passenger injuries in crashes involving electric vehicles is actually slightly lower, meaning that they are safer to passengers, than those involving vehicles with gasoline and diesel engines. However, the overall cost of collision repairs and replacements of electric vehicles averaged far higher than their petroleum-powered counterparts.
