    摘要： A method for rapidly determining an initial diffusion voltage (Vdiff)initial as a starting point in calculating a diffusion voltage in an electro-chemical cell (e.g., a battery used in an automotive vehicle) includes obtaining a time difference toff between a time when the cell was last turned-OFF and a time when the cell was next turned-ON, selecting a starting diffusion voltage (Vdiff)start based on toff, determining a trial diffusion voltage Vdiff based on a diffusion circuit model and (Vdiff)start, calculating an error voltage Verror=(Vdiff)−|VOFF−VON| where VOFF and VON are cell voltages at turn-OFF and turn-ON respectively, repeating the foregoing determining and calculating steps using for each iteration (Vdiff)start=(Vdiff)previous+Verror until Verror is less than or equal to a first predetermined tolerance amount ε, storing in a memory a value of Vdiff corresponding to the condition Verror≦ε, and setting (Vdiff)initial equal to the just stored value of Vdiff. A further diffusion voltage Vdiff is then determined using the same diffusion circuit model and the just obtained (Vdiff)initial and is advantageously used by a controller in an electric propulsion vehicle to determine a state of charge of the propulsion battery.

    摘要： Methods and systems for determining a state of charge of a battery are provided. A first component of the state of charge is calculated based on a first property of the battery. A second component of the state of charge is calculated based on a second property of the battery. The first component of the state of charge is weighted based on a rate of change of the first property relative to a change of the state of charge. The second component of the state of charge is weighted based on a rate of change of the second property relative to a change of the state of charge. The state of charge is determined based on the first and second weighted components.
