The safety of electric vehicles (EVs) has been a topic of concern for many consumers, with high-profile fire incidents often sparking fears about EV crash safety. However, research on vehicle safety, particularly in terms of impact injuries in motor vehicle crashes, reveals a more nuanced perspective on the safety of EVs. Crash testing procedures for EVs and internal combustion vehicles are similar, with both undergoing evaluations by organizations like the National Highway Safety Administration’s New Car Assessment Program and the Insurance Institute for Highway Safety using crash test dummies to assess occupant protection and fire hazard risks. While media attention on EV fire hazards may be exaggerated, data from crash tests and field injury analysis suggest that EVs offer superior occupant protection compared to internal combustion vehicles.
One of the key reasons for the safety advantage of EVs lies in their design and technology. The weight and placement of battery packs in EVs result in lower centers of gravity and reduce the risk of rollover accidents, which are often fatal. In collisions, the heavier weight of EVs offers an advantage in terms of occupant protection due to reduced deceleration rates. Additionally, newer EV models come equipped with advanced safety features such as energy-absorbing materials, crash avoidance systems, and upgraded seat belts and airbags, further enhancing occupant protection. Crash tests from organizations like the Insurance Institute for Highway Safety consistently show that most EVs are safe for their occupants.
Despite the safety benefits of EVs for their occupants, they also pose challenges in terms of crash compatibility with other vehicles. Heavier EVs can impose a higher crash energy burden on lighter vehicles, increasing the risk of injuries for occupants in the lighter vehicle. The increased energy associated with impacts from heavier EVs, particularly electric pickups, can also pose challenges for highway guardrails. Additionally, the quiet operation of EVs at low speeds can make them a risk for pedestrians, bicyclists, and others who may not hear them approaching. Addressing these safety challenges will require technological advancements in materials, sensing technologies, safety algorithms, seat belts, and airbags.
Technological advancements are expected to play a crucial role in improving the safety of EVs, both for their occupants and for others on the road. Continual advancements in lightweight materials, sensing technologies, safety algorithms, seat belts, and airbags are expected to enhance occupant protection in EVs. The intersection of EVs with rapidly evolving computing capabilities is also likely to spur the development of new safety technologies that address the unique challenges posed by EVs on the road. As the automotive industry continues to shift towards electric vehicles, ensuring the safety of these vehicles will be a key priority for both manufacturers and regulators.
