Lightning struck an electric car in China multiple times, but the passengers remained unscathed.
In a remarkable demonstration of safety, an electric vehicle (EV) - the BYD Song EV - remained undamaged and kept its passengers unharmed during a series of lightning strikes in China.
The metal body of the EV functioned as a Faraday cage, directing the lightning current safely around the occupants and into the ground without penetrating the interior. This phenomenon, consistent with the Faraday cage principle, was evident in the incident.
Upon the first lightning strike, the vehicle's power-off protection system immediately activated, safeguarding the EV's electrical components by disconnecting power. This crucial measure prevented damage to the circuitry and ensured passenger safety within the cabin.
Additional safety features include surge protection devices and grounding systems designed for electric vehicles and charging stations. These components manage overvoltages caused by lightning strikes or electromagnetic pulses, shielding the vehicle's onboard electronics from damage.
In summary, the safety of passengers in an EV struck by lightning arises from the vehicle's metal body acting as a Faraday cage, built-in power-off protection systems, surge protection and grounding, and adherence to lightning safety designs integrated into the vehicle's electrical and structural systems.
The occupants of the electric car survived the incident unharmed, and the rest of the vehicle remained undamaged externally after the lightning strikes. A video from China shows the BYD Song EV being struck by lightning three times in a row in Beihai, China.
It is worth noting that electric cars, such as the BYD Song EV, are not more prone to fires than vehicles with internal combustion engines. However, it is advisable to close windows, sunroofs, and retract all antennas during a thunderstorm, as recommended by the automobile club ADAC. Additionally, it is advised to avoid parking at elevated points during a thunderstorm.
In the case of a convertible, the roof should be closed to create an effective Faraday cage. An aluminum outer skin or a plastic paneling on a metal frame also acts as a Faraday cage, according to the ADAC.
Following the incident, the electric car struck by lightning in China was inspected by a dealer and showed no signs of a short circuit in the core components - battery pack, electronic control unit, and motor. This further underscores the safety measures built into electric vehicles.
In conclusion, electric cars offer no less safety than conventional models during a lightning strike. They act as a Faraday cage, protecting their passengers and internal components from the electrical charge.
