Low voltage battery health diagnostics

A system for evaluating a low voltage (LV) battery system, comprising:

• a processing device configured to collect parameters of the LV battery system, the parameters including at least one of a voltage, a current, a temperature and a state of charge (SOC), the processing device configured to determine 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, identify a cause of the unhealthy condition based on a selection of a set of health indicators, wherein the processing device is configured to determine the health by:
• identifying an enabling condition of the battery system, the enabling condition related to charging or discharging of the battery system;
• selecting the set of the health indicators based on the identified enabling condition, and 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.

A vehicle system, comprising:

• a low voltage (LV) battery system configured to power LV components of a vehicle;
• and
• a processing device configured to collect parameters of the LV battery system, the parameters including at least one of a voltage, a current, a temperature and a state of charge (SOC), the processing device configured to determine 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, identify a cause of the unhealthy condition based on a selection of a set of health indicators, wherein the processing device is configured to determine the health by:
• identifying an enabling condition of the battery system, the enabling condition related to charging or discharging of the battery system;
• selecting the set of the health indicators based on the identified enabling condition, and 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.
