  • Patent number: 11970078
    Abstract: A system in a vehicle includes memory to store values obtained for a battery that supplies current to one or more loads. The values include battery state of charge. A processor obtains a measured battery current from a battery current sensor and a measured total current from a current sensor at a battery center that supplies the current directly to the one or more loads, obtain a generator current or a direct current-to-direct current (DC-DC) converter current from the measured total current and the battery current, determine a maximum available current as a sum of a maximum available battery current and either the generator current or the DC-DC converter current, and stop a supply of the current to one or more of the one or more loads based on a result of a comparison of the maximum available current with current draw by the one or more loads.
