Abstract

A vehicle on-board electrical system is equipped with a DC voltage charging connection, a non-configurable accumulator, a galvanically isolating DC-DC voltage converter, and an electrical drive. The accumulator is connected to a first side of the DC-DC voltage converter via a switchable connection circuit to which a DC voltage charging connection is connected. The accumulator is connected to the electrical drive and a second side of the DC-DC voltage converter via a drive switch. The connection circuit has a direct connection switch that connects the accumulator to the first side of the DC-DC voltage converter in a switchable manner. The DC voltage charging connection is connected to the direct connection switch via a charging connection switch of the connection circuit.
