How safe is an EV battery pack?

An EV battery pack contains a series of individual cells and takes up majority of the floor estate in the car. With the significant size of it in the floorboard of the chassis, how safe is the battery of an EV? The main concern is the combustion risk of a battery, and this has to do with the organic liquid electrolyte.

Are battery fires a risk in an EV accident?

While incredibly unlikely, battery fires are still a risk in the event of a collision. Australian emergency services are trained in accident responses for electric vehicles. Many EVs will detach the connections to the battery once airbags are deployed. Emergency responders are trained on how to remove the battery if required.

Are batteries safe to use?

The safety and performance of batteries remains a top concern whatever their use. Conformity assessment, such as testing and certification, plays an important role.
