US Classification:

320156, 320104, 320136, 903903

Abstract:

A method for rapidly determining an initial diffusion voltage (V)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 tbetween a time when the cell was last turned-OFF and a time when the cell was next turned-ON, selecting a starting diffusion voltage (V)based on t, determining a trial diffusion voltage Vbased on a diffusion circuit model and (V), calculating an error voltage V=(V)−|V−V| where Vand Vare cell voltages at turn-OFF and turn-ON respectively, repeating the foregoing determining and calculating steps using for each iteration (V)=(V)+Vuntil Vis less than or equal to a first predetermined tolerance amount ε, storing in a memory a value of Vcorresponding to the condition V≦ε, and setting (V)equal to the just stored value of V. A further diffusion voltage Vis then determined using the same diffusion circuit model and the just obtained (V)and is advantageously used by a controller in an electric propulsion vehicle to determine a state of charge of the propulsion battery.

Abstract:

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.

International Classification:

G01R 31/36

US Classification:

702 63

Abstract:

A method for estimating vehicle battery parameters that uses two different sampling rates. The method samples a battery terminal voltage and current at a high sampling rate to estimate the battery open circuit voltage and high frequency resistance. The battery state of charge (SOC) is derived from the open circuit voltage. Next, the battery terminal voltage and current are re-sampled at a low sampling rate. Other battery parameters can be extracted from the low-rate sampled signals. Next, all of the battery parameters that were obtained from the two sampling rates are used together to predict battery power.

US Classification:

702 63, 320137, 702 65

Abstract:

A method of determining a state of health of a battery in real time includes estimating a parameter value associated with the state of health of the battery and determining one or more of a terminal voltage, an accumulated charge, a state of charge, and a temperature of the battery. The method further includes determining, via a computing device, a reserve capacity of the battery based at least in part on the estimated parameter value and one or more of the terminal voltage, the accumulated charge, the state of charge, and the temperature of the battery.
