Abstract
A method for battery authentication includes, at a battery controller of a battery subsystem, measuring a test electrochemical impedance spectroscopy (EIS) response of one or more battery cells connected to the battery controller. The test EIS response is compared to a historical EIS response stored in a storage subsystem, wherein the historical EIS response corresponds to one or more authentic battery cells associated with the battery controller. Based at least in part on a measured similarity between the test EIS response and the historical EIS response, the battery controller outputs an authenticity determination for the one or more battery cells connected to the battery controller.
