METHODS FOR CONTROLLING A POWER LEVEL IN AN ENERGY SOURCE OF A VEHICLE UNIT

A method for controlling an articulated vehicle combination comprising a plurality of self-powered vehicle units, wherein each self-powered vehicle unit comprises a propulsion device and a regenerative braking device connected to an energy source, the method comprising determining a current state of charge associated with an energy source of a target vehicle unit comprised in the plurality of self-powered vehicle units, and if the current state of charge is below a desired state of charge, generating a negative torque by the regenerative braking device of the target vehicle unit, and compensating at least partly for the generated negative torque by generating a positive torque by the propulsion device of at least one source vehicle unit comprised in the plurality of self-powered vehicle units, thereby transferring an amount of energy from the energy source of the at least one source vehicle unit to the energy source of the target vehicle unit.
