In the realm of automotive technology, the future is electric. However, concerns about the safety of electric vehicles (EVs) persist among the general public. These concerns often stem from high-profile incidents of fires involving EVs. Despite this, research suggests that the safety of EVs is actually quite nuanced and requires a closer examination.
Crash-testing procedures used to evaluate the safety of both EVs and internal combustion vehicles are conducted by organizations such as the National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety. These tests assess the crashworthiness and occupant protection of a vehicle using crash test dummies to simulate different scenarios. While the media often sensationalizes EV fires, actual data from crash tests does not support the notion that EVs are more dangerous.
One key advantage of EVs in terms of safety is their weight and center of gravity. With battery packs positioned at the base of the car, EVs tend to have lower centers of gravity and more weight, reducing the risk of rollover accidents. In collisions between vehicles, the heavier one typically sustains less damage and protects its occupants better. Additionally, EVs are equipped with advanced safety systems that further enhance occupant protection.
However, EVs do pose unique safety challenges. Their increased weight means that other vehicles involved in collisions with EVs must absorb more crash energy, potentially causing higher injury risks for their occupants. This concept, known as crash compatibility, also applies to pedestrians and bicyclists who may be at increased risk from quieter EVs operating at low speeds. Addressing these challenges will require advancements in safety technologies and materials.
Technological advancements are likely to play a crucial role in improving the safety of EVs for all road users. Lightweight materials, advanced sensing technologies, and safety algorithms, as well as enhanced seat belts and airbags, will be key in addressing safety concerns. The connection between EVs and rapidly evolving computing capabilities suggests that new safety technologies will continue to be developed and implemented to enhance the safety of EVs on the road.
