  • Methods, systems, and devices for monitoring state-of-health of a battery system operating over an extended temperature range
    Patent number: 10712396
    Abstract: Disclosed herein are methods, systems, and devices for determining a state-of-health (SOH) of battery systems over extended temperatures. According to one embodiment, a computer implemented method includes (1) receiving measured temperature data and measured ohmic value data associated with a battery cell; (2) determining an estimated battery cell electrolyte temperature based on the measured temperature data; (3) determining a normalized ohmic value based on the measured ohmic value data and the estimated battery cell electrolyte temperature, wherein the normalized ohmic value is related to a normalized temperature; and (4) transmitting, to at least one of a graphical user interface (GUI) and a battery log, an indication of an SOH of the battery cell based upon the normalized ohmic value being greater than a normalized maximum ohmic value, wherein the normalized maximum ohmic value is indicative of an abnormal SOH of the battery cell for the normalized temperature.
