Method of diagnosing lithium-ion battery and diagnostic apparatus for lithium-ion battery |
| abstract |
The first information associated with the charge capacity of the lithium ion battery and the index value is obtained. Using the first information, the index value is expressed as a function [f(x)] of the charging capacity, and the extreme value point at which the second derivative [f''(x)] of the function [f(x)] takes the minimum value is calculated. do. The lithium ion battery is diagnosed using the charging capacity (x e ) of the extreme value point. The lithium ion battery contains at least silicon oxide and graphite in the negative electrode. The index value can be measured from the outside of the lithium ion battery. The index value reflects the volume of silicon oxide and graphite. |
