Abstract
A system with a high-voltage battery and a coupling device that couples the high-voltage battery to a high-voltage onboard power supply system of a motor vehicle. The coupling device couples a positive pole and a negative pole with corresponding phases of the high-voltage power supply system. The coupling device includes a current measurement device that measures the current flowing between a first electrically conductive connection and a first interface and/or the current flowing between a second electrically conductive connection and a second interface, an actuating device, and at least one first semiconductor switch, as well as at least one second semiconductor switch, which is coupled between the second electrically conductive connection and the second interface. The first semiconductor switch includes a first control electrode and the second semiconductor switch includes a second control electrode, which are coupled to the actuating device.
