  • Battery life assessment and capacity restoration
    Patent number: 11658354
    Abstract: Described herein are embodiments of methods and apparatus for determining the SoC and SoH a lithium ion battery and for restoring capacity to a lithium ion battery. Some embodiments provide a method and apparatus including an ultrasound transducer designed to measure characteristics of a lithium ion battery in order to determine the SoC and SoH of the lithium ion battery, and to disrupt the SSEI layer inside the lithium ion battery. Several other methods for determination of SoC and SoH and disruption of the SSEI layer are also described. Use of such methods and apparatus may be advantageous in assessing a state of the lithium ion battery, as well as rejuvenating a lithium ion battery and increasing its life span.
