CHARGE CONTROL OF LITHIUM ION CELL

摘要

PROBLEM TO BE SOLVED: To provide a charge control method capable of extending the service life of a lithium ion cell.SOLUTION: The charge control method includes a process for receiving a potential value of a negative electrode of a lithium ion cell and a process for adjusting a voltage of a constant voltage phase on the basis of at least a part of a potential value of the negative electrode for a cell charging process of the lithium ion cell. The receiving process may include measurement of the potential value of the negative electrode relative to a reference electrode of the lithium ion cell.
