Disclosed is a computer-implemented method and system for operating an auxiliary power unit (APU) in a range-extended electric vehicle between a minimum state of charge (SoC) limit and a maximum SoC limit of the battery pack, including predicting expected energy use profile of said vehicle; predicting change in SoC for both “APU off” and “APU on” states at a predetermined power setting corresponding to the desired optimal point (for example, the most efficient, or most powerful, or most comfortable, or lowest noise) for the specific vehicle and APU type in question; setting SoC limits for said battery pack at end of journey to minimum acceptable values based on the design and characteristics of the battery pack; and, working iteratively in reverse order from the end of journey, using “APU on” SoC values to set the minimum-limit of SoC, and “APU off” value to set the maximum-limit of SoC. |
