BATTERY CELL STATE-OF-CHARGE ESTIMATION AND READJUSTMENT METHOD |
| 摘要 |
A method of detecting a predetermined specific value of the charge contained in a first elementary cell of a battery, including the steps of: measuring the voltage across the cell under reference current at a plurality of times in a phase of cell charge or discharge between first and second state-of-charge levels; and detecting a predetermined specific value of this voltage, corresponding to the specific charge value. |

1. A method of detecting a predetermined specific value of the charge contained in a first elementary cell of a battery, comprising the steps of:
measuring the voltage across the cell at a plurality of times in a phase of cell charge or discharge between first and second state-of-charge levels; and detecting a predetermined specific value of this voltage, corresponding to the specific charge value, said specific charge and voltage values corresponding to the coordinates of a crossing point of at least two curves representative of variation of said voltage according to the charge contained in the cell, for different states of health of the cell. |
