Abstract
A method for optimising the power of an electrified vehicle having at least one electrical energy accumulator, at least one electrical drive and at least one auxiliary unit, the electrical energy accumulator having a maximum discharge power and a continuous discharge power. The power available from the electrical energy accumulator is distributed intelligently in order to make vehicle operation which is acceptable to the driver of the electrified vehicle possible.
Claims12
A method for optimizing power of an electrified vehicle, which comprises at least one electrical energy accumulator, at least one electrical drive, and at least one auxiliary unit, the electrical energy accumulator having a maximum discharge power and a continuous discharge power, the method comprising:
- making the maximum discharge power available to the electrical drive and/or the at least one auxiliary unit in a certain energy contingent;
- reducing the maximum discharge power to the continuous discharge power after the certain energy contingent is used up;
- and
- reducing a power of the at least one auxiliary unit depending on the certain energy contingent of the maximum discharge power that is still available when a limit value is exceeded by a power demand for the electrical drive and the power of the at least one auxiliary unit, the energy contingent that is still available being non-zero,
- wherein the limit value is defined by the continuous discharge power of the electrical energy accumulator.
A vehicle, comprising:
- at least one electrical energy accumulator having a maximum discharge power and a continuous discharge power;
- at least one electrical drive;
- at least one auxiliary unit;
- and
- at least one power control unit,
- wherein the power control unit makes the maximum discharge power available to the electrical drive and/or the at least one auxiliary unit in a certain energy contingent, the power control unit reduces the maximum discharge power to the continuous discharge power after the certain energy contingent is used up, and the power control unit reduces a power of the at least one auxiliary unit depending on the certain energy contingent of the maximum discharge power that is still available when a power demand for the electrical drive and the power of the at least one auxiliary unit exceed a limit value, the energy contingent that is still available being non-zero, and
- wherein the limit value is defined by the continuous discharge power of the electrical energy accumulator.
