ABSTRACT:
The brake system having an electrically controllable brake apparatus of a trailer, the brake apparatus includes a control unit which is connected via electrical lines to an electrical energy source of a tractor. In braking, electrical currents are brought about of such a magnitude as to cause severe voltage drops in long lines that the functional safety of the brake apparatus may be threatened. The brake apparatus therefore has an electrical energy storage device disposed on the trailer, which can be charged by an energy source of the tractor and can be discharged upon triggering of the brake apparatus of the trailer. Voltage drops in the relatively short lines between the energy storage device and the control unit are therefore minimum. The lines between the electrical energy source of the tractor and the energy storage device of the trailer are charged by only low charging currents. The voltage drop is therefore low despite the long line length.
