Abstract:
1. A method for estimating a range of a vehicle with a rechargeable energy storage system (RESS) for a current drive cycle, the method comprising: obtaining a time of day for the current drive cycle; determining a particular time interval corresponding to the time of day, wherein the particular time interval comprises one of a plurality of time intervals, each time interval generally associated with a respective temperature range relative to other of the plurality of time intervals; determining an amount of energy available from the RESS; calculating an average amount of energy used by the vehicle during a first plurality of previous drive cycles, each of the first plurality of previous drive cycles occurring during the particular time interval of a respective day; and estimating, via a processor, the range for the vehicle based on the amount of energy available from the RESS and the average amount of energy used by the vehicle during the first plurality of previous drive cycles.
