Abstract
The invention relates to a method for determining the end-of-charging condition of a lithium-ion accumulator with a negative electrode formed with at least one alloy, according to which a surface pressure with a determined force from the external portion of the accumulator (A) against an element (2, 2′, 3) is detected, the surface pressure being generated by the thickness increase due to ion insertion at the negative electrode and thereby defining the end-of-charging condition.
