Abstract
A battery apparatus estimates a surface SOC representing a potential at an electrode surface of the battery, and predicts an output of the battery during a requested time based on the first surface SOC, a cut-off voltage, and the requested time.
Claims20
A battery apparatus, comprising:
- a battery;
- and
- a processor configured to:
- estimate a surface state of charge (SOC) representing a potential at an electrode surface of the battery as a first surface SOC;
- determine the surface SOC at a time when a terminal voltage of the battery becomes a cut-off voltage as a second surface SOC;
- estimate a current of the battery for allowing the second surface SOC to be estimated from the first surface SOC after a requested time;
- and
- predict an output of the battery during the requested time based on the estimated current;
- and
- manage the battery to output power to an external apparatus based on the predicted output.
