  • SYSTEMS AND METHODS FOR DIAGNOSING FAULTS ASSOCIATED WITH THE USE OF A PRIMARY POWER SUPPLY AND A BACKUP POWER SUPPLY
    Publication number: 20200143609
    Abstract: A power supply diagnostics system is disclosed. The power supply diagnostics system includes a first direct current to direct current (DC/DC) control module configured to change an output of a first variable DC/DC converter and a second DC/DC control module configured to change an output of a second variable DC/DC converter. The first and second variable DC/DC converters are connected to a load. The power supply diagnostics system also includes: a first timer module; a second timer module; a first voltage comparison module configured to (i) store a voltage measured at the load based on an output of the first timer module and (ii) begin sampling a plurality of voltages measured at the load base on an output of the second timer module; and a DC/DC status module configured to change an operating parameter of a vehicle based on a comparison of the voltage and the plurality of voltages.
