| titleOfInvention | SYSTEM AND METHOD FOR EVALUATION OF THE STATE OF CHARGE OF A LITHIUM BATTERY CELL IN A VEHICLE |
| abstract | Method and system for estimating the state of charge of a vehicle lithium battery cell. The method includes providing a non-linear function of the lithium battery cell, a normalized lithium surface density, and an actual voltage at current of the lithium battery cell with an internal resistance. The method further includes determining an actual lithium surface density based on the actual voltage versus an inverse of the non-linear function. The method further includes determining a varying parameter based on actual lithium surface density relative to a first diffusion model. The method further includes determining a predicted lithium surface density based on the varying parameter relative to a second diffusion model. The method further includes determining an estimated state of charge of the lithium battery cell when a difference between the predicted and actual lithium surface densities is less than a first threshold. |
