In the case of the burning batteries of electric cars, the fire is almost impossible to delete. “The battery supplies the oxygen for the fire.

An E-car in an underground garage or a garage fire, the fire brigade is faced with major problems.
“We have advised the competent Authorities on the issue. In the case of charging stations in garages and Parking halls of the preventive fire should be adapted protection,” says Urs baechtold from the Swiss fire brigade Association.

The firefighters poking at the fire protection provisions to the competent Cantonal fire insurance Association (VKF) on deaf ears. “At the Moment, we assume that electric vehicles have a larger danger than of vehicles with internal combustion engine and the corresponding fuel tank,” says Michael Binz of the VKF.
