SYSTEMS AND METHODS FOR DETERMINING BATTERY SYSTEM POWER CAPABILITY |
| 摘要 |
System and methods for determining battery system power capability in a vehicle are presented. Peak power capability estimation systems and methods disclosed herein may compensate regressed parameters in a battery system circuit model for an effect of current magnitude. Utilizing the disclosed methods for accurately estimating peak power capability of a battery system may provide for, among other things, improved battery system performance modeling and/or improved battery system control and management decisions. |

1. A method of determining a peak power capability of a battery system comprising:
identifying a peak current of the battery system; determining a regressed ohmic resistance in a battery system model used to model the battery system; scaling the regressed ohmic resistance to calculate a compensated ohmic resistance of the battery system model based on the peak current; and determining a peak power capability of the battery system based on the compensated ohmic resistance and the battery system model. |
