Abstract

A method for non-invasive characterization of an electrical charge storage device such as a lithium battery, containing lithium ions or lithium metal, the method comprising. The method includes the steps of a) providing at least one electric charge storage device; b) measuring a magnetic field generated by the at least one electrical charge storage device using at least one magnetic field sensor positioned in electromagnetic communication_to the electrical charge storage device; c) acquiring magnetic field data; and, d) determining the condition of the at least one electrical charge storage device using the magnetic field data. The method is operable and effective without magnetic shielding from external magnetic fields, including Earth's magnetic field.
