An electrically drivable motor vehicle with at least two parallel connectable vehicle batteries is provided with an electronic circuit arrangement. The electronic circuit arrangement includes a number of electronic load interrupter switches corresponding to the number of vehicle batteries, via which the vehicle batteries can be connected through individually or together to an electrical consumer. The load interrupter switches respectively comprise two power branches arranged anti-parallel to each other.

The invention relates to an apparatus for finding a parked vehicle again. According to the invention, a portable unit is provided with a pressure sensor whose signals can be evaluated by an evaluation and control unit in order to determine the current air pressure, with the evaluation and control unit evaluating the determined air pressure in order to determine altitude, and storing a first air pressure value as a reference value at a predeterminable first time, which reference value represents an instantaneous altitude of a geographic position of the parked vehicle, with the evaluation and control unit estimating a height difference between a current geographic position of the portable unit and the geographic position of the parked vehicle at a second time, and/or continuously from a pressure difference between the determined current air pressure value and the reference value.
