Abstract
Disclosed herein are regulated power supplies. The power source delivers power to a system load and includes battery units. The power source also includes power flow devices coupled to the battery units that are configured to provide power from the battery units to the system load. Each power flow device corresponds to a respective one of the battery units, and includes a one direction current flow device connected in series with a current regulator between the respective battery unit and the system load.
Claims20
A power source for delivering power to a system load when connected, the power source comprising:
- a plurality of battery units;
- a plurality of power flow devices coupled to the plurality of battery units and configured to provided power from the plurality of battery units to the system load when connected, each power flow device corresponding to a respective one of the plurality of battery units, each power flow device including a one direction current flow device connected in series with a current regulator between the respective battery unit and the system load when connected.
A power supply regulation method for supplying power to a system load when connected, the method comprising:
- setting a respective current limit to a respective initial value for each of a plurality of battery units, each of the plurality of battery units including a one direction current flow device connected in series with a current regulator between the respective battery unit and a system load when connected;
- monitoring a state of charge of each of the plurality of battery units;
- and
- individually adjusting the respective current limit of at least two of the plurality of battery units based on the monitored state of charge of each of the plurality of battery units.
