| titleOfInvention | An online life prediction method for lithium batteries based on two-point life characteristics |
| abstract | The invention discloses a lithium battery online life prediction method based on two-point life characteristics. The present invention includes the following steps: 1. collecting the charging voltage, charging capacity and service life of a brand-new lithium battery in different charge-discharging cycles, and obtaining two corresponding voltage-capacity curves; 2. calculating and obtaining the capacity difference curve of the current lithium battery; 3. calculating all charging Two-point life characteristics corresponding to the voltage combination; 4. Repeat steps 1-3 to obtain the life of each lithium battery and the two-point life characteristics corresponding to all charging voltage combinations of each lithium battery; 5. Select the best charging voltage combination and the best two-point life Life characteristics constitute the training set; 6. Obtain the regression model for predicting the life of the lithium battery after training; 7. During online diagnosis, collect and obtain the best two-point life characteristics to be predicted for the lithium battery to be predicted, and the prediction output obtains the current lithium battery to be predicted. life. The invention realizes the accurate prediction of the life of the lithium battery, and improves the reliability, safety and durability of the lithium battery. |
