Claim 0:
1. A method for controlling transfer of electrical energy in a coupling between a first vehicle and a second vehicle of a vehicle combination, comprising:
determining, by a control system comprising processing circuitry, an amount of possible excessive energy from a regenerative braking event of the second vehicle operable in a generator mode for generating electrical energy, each of the first vehicle and the second vehicle having an electric machine and an energy storage system (ESS), at least the electric machine of the second vehicle operable in a traction mode and the generator mode;
determining, by the control system, a total energy level of the second vehicle,
determining, by the control system, a total energy level of the first vehicle,
comparing, by the control system, the determined amount of possible excessive energy with the determined total energy levels of the first vehicle and second vehicle, and
controlling, by the control system, direction of the transfer of electrical energy between the first vehicle and the second vehicle based on the comparison.
