Abstract
Electric vehicle predictive range estimating systems and methods are provided herein. An example method includes determining an initial state of charge (SOC) for an energy source of a vehicle at a first point in time; determining one or more boundary conditions for the vehicle during a time frame extending from the first point in time to a second point in time, the one or more boundary conditions causing a loss in the energy source during the time frame; determining a predicted future SOC for the energy source based on the one or more boundary conditions and the initial SOC; and predicting an availability of a vehicle operating condition based on the predicted future SOC for the energy source.
Claims10
A method, comprising:
- determining a first initial state of charge (SOC) for a low-voltage battery of a vehicle and a second initial SOC for a high-voltage battery of the vehicle at a first point in time, the low-voltage battery and high voltage battery comprising an energy source of the vehicle;
- determining one or more boundary conditions for the vehicle during a time frame extending from the first point in time to a second point in time, the one or more boundary conditions causing a loss in the low-voltage battery and the high-voltage battery during the time frame;
- determining a first predicted future SOC for the low-voltage battery and a second predicted future SOC for the high-voltage battery based on the one or more boundary conditions and the first initial SOC and second initial SOC;
- determining that the first predicted future SOC is below a threshold value and the second predicted future SOC is above the threshold value;
- and
- determining, based on the determination that the first predicted future SOC is below the threshold value and the second predicted future SOC is above the threshold value, a no-start condition of the vehicle.
A method, comprising:
- determining an initial state of charge (SOC) for an energy source of a vehicle at a first point in time;
- determining one or more boundary conditions for the vehicle during a time frame extending from the first point in time to a second point in time, the one or more boundary conditions causing a loss in the energy source during the time frame;
- determining a predicted future SOC for the energy source based on the one or more boundary conditions and the initial SOC;
- predicting an availability of a vehicle operating condition based on the predicted future SOC for the energy source;
- receiving an indication of the second point in time from a user through a human machine interface (HMI) of the vehicle;
- and
- displaying the predicted future SOC on the HMI, wherein the HMI provides a graphical user interface having:
- user inputs corresponding to a duration of the time frame, a current ambient temperature, and an estimated ambient temperature at the second point in time;
- an indication of a number of days until a no-start condition for the energy source is reached based on the initial SOC and the one or more boundary conditions based on the user inputs;
- a selection of a minimum desired range;
- an indication of a time until the minimum desired range has been reached based on the user inputs and the selection of the minimum desired range;
- and
- a toggle allowing charging for a low-voltage battery of the energy source to be selectively activated or deactivated.
