Abstract
This disclosure relates to an electrified vehicle and a method for gradually adjusting a displayed state of charge. An exemplary electrified vehicle includes a battery, a display configured to display a state of charge of the battery, and a controller configured to adjust the displayed state of charge such that the displayed state of charge gradually converges to an estimated state of charge of the battery.
Claims17
An electrified vehicle, comprising:
- a battery;
- a display configured to display a state of charge of the battery;
- and
- a controller configured to continuously or in regular intervals:
- calculate an estimated state of charge of the battery, calculate either a discharge rate of the battery when the battery is discharging or a charge rate of the battery when the battery is charging, and selectively adjust the displayed state of charge,
- wherein, when the battery is discharging and the estimated state of charge exceeds the displayed state of charge, the controller is configured to adjust the displayed state of charge at a rate of less than one times the discharge rate of the battery until the displayed state of charge is equal to the estimated state of charge.

A method, comprising:
- calculating continuously or in regular intervals both an estimated state of charge and either a charge rate when the battery of an electrified vehicle is charging or a discharge rate when the battery of the electrified vehicle is discharging;
- and
- adjusting a displayed state of charge of the battery of the electrified vehicle, wherein, when the battery is discharging and the estimated state of charge exceeds the displayed state of charge, the adjusting step includes adjusting the displayed state of charge at a rate of less than one times the discharge rate of the battery until the displayed state of charge is equal to the estimated state of charge.
An electrified vehicle, comprising:
- a battery;
- a display configured to display a state of charge of the battery;
- and
- a controller configured to continuously or in regular intervals:
- calculate an estimated state of charge of the battery, calculate either a discharge rate of the battery when the battery is discharging or a charge rate of the battery when the battery is charging, and selectively adjust the displayed state of charge,
- wherein the controller is configured to identify a difference between the displayed state of charge and the estimated state of charge,
- wherein the controller monitors for the difference between drive cycles of the electrified vehicle
- wherein the controller is configured to calculate a first estimated state of charge during a first drive cycle;
- wherein the controller causes the display to display the first estimated state of charge;
- wherein the controller is configured to calculate a second estimated state of charge during a second drive cycle different than the first drive cycle;
- and
- when the second estimated state of charge differs from the first estimated state of charge, the controller is configured to adjust the displayed state of charge such that the displayed state of charge converges from the first estimated state of charge to the second estimated state of charge.
