Abstract
Electrically driven passenger transport vehicles are supplied with energy by an external electric supply network. If the external energy supply fails, vehicles of this type require special auxiliary devices that do not rely on the supply network, for example rely on auxiliary vehicles, in order to move said vehicles again. A vehicle can move independently during a failure of the external energy supply, by switching the electric drive of said vehicle to a battery drive.
