Are electrical vehicles a greater fire risk than traditional vehicles?

Contrary to popular belief, internal combustion engine (ICE) vehicles are about 20 times more likely to catch fire than EVs, according to 2022 research by the Swedish Civil Contingencies Agency. However, EV fires are more dangerous due to higher temperatures, thermal runaway, and explosions. Fires in underground locations, like car parks, can be especially hazardous.

Mitigating electrical vehicle fire risks in commercial buildings
There are several ways to reduce the risk of EV fires in buildings:

EV charging infrastructure: Position chargers away from combustible materials, use ventilation, and group chargers in one location. Install chargers on non-combustible surfaces and ensure installers are certified.
Fire suppression: For indoor or underground chargers, install sprinklers and fire detection systems, and ensure chargers can be shut off automatically during a fire. Create fire-resistant compartments around charging areas.
Maintenance: Regularly maintain and inspect EV chargers and have processes in place for repairs.

Additional considerations for e-bikes and e-scooters
These vehicles have lower voltage but may use substandard batteries, increasing fire risk. Avoid charging them in hallways or fire escapes, and do not use multi-plug adapters. Managing agents should monitor for safety hazards and ensure repairs are addressed promptly.

Though EV infrastructure presents new risks, regular risk assessments and proactive measures can minimize hazards, lower insurance premiums, and ensure swift claim approval.
