1. A braking system comprising:
a first input voltage terminal;
a second input voltage terminal;
an electric motor; and
a switchable connection between a first connection point connected to the first input voltage terminal and a second connection point connected to the second input voltage terminal and the electric motor,
wherein the switchable connection is open in normal operation, and
wherein in response to a detected voltage difference between the first input voltage terminal and the second input voltage terminal which is above a first threshold value, the electric motor is configured to operate in a recuperation mode, and in response to a detected voltage difference between the first connection point and the second connection point which is below a second threshold value, the switchable connection is closed.
