OPTIMIZING CHARGE/DISCHARGE PLANS FOR ELECTRIC VEHICLES
First Claim
1. A method for determining a charge plan for an electrical energy store of a vehicle, the method comprising the acts of:
- subdividing a charging time interval, which is available for charging the energy store, into a sequence of time segments, such that constant charging power conditions are respectively present in the time segments in the sequence of time segments;
determining, for each time segment in the sequence of time segments, a limited number of possible charging powers with which the energy store can be charged and/or discharged in the respective time segment;
determining a plurality of sequences of charging points, wherein each of the charging points indicates a charging power from the limited number of possible charging powers for a given time segment from the sequence of time segments, and wherein each sequence of charging points from the plurality of sequences of charging points indicates a sequence of charging powers for the sequence of time segments; and
selecting a sequence of charging points from the plurality of sequences of charging points as the charge plan.

Abstract
A method for determining a charge plan for an electrical energy store of a vehicle includes subdividing a charging time interval, which is available for charging the energy store, into a sequence of time segments, such that constant charging power conditions are respectively present in the time segments in the sequence of time segments. For each time segment in the sequence of time segments, a limited number of possible charging powers with which the energy store can be charged and/or discharged in the respective time segment are determined. A plurality of sequences of charging points are determined, where each of the charging points indicates a charging power from the limited number of possible charging powers for a given time segment from the sequence of time segments, and where each sequence of charging points from the plurality of sequences of charging points indicates a sequence of charging powers for the sequence of time segments. A sequence of charging points from the plurality of sequences of charging points is then selected as the charge plan.
