Abstract
A method of evaluating a low voltage (LV) battery system includes collecting parameters of the LV battery system, determining a health of the LV battery system based on one or more health indicators of a plurality of health indicators, and based on determining that the battery system is in an unhealthy condition, identifying a cause of the unhealthy condition based on selection of a set of health indicators. Determining the health includes identifying an enabling condition related to charging or discharging of the LV battery system, selecting a set of health indicators from the plurality of health indicators based on the identified enabling condition, estimating a value of each of the set of health indicators, and determining whether the LV battery system is in a healthy condition or the unhealthy condition based on the collected parameters and the value of each of the set of health indicators.
