Electrically drivable motor vehicle with two anti-parallel power branches

摘要

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.
