Abstract
In some examples, an electrical power system includes a power source and a load modulator configured to receive power from the power source and to deliver power to a load zone. The electrical power system also includes a controller configured to determine a software-controlled power flow limit for the load zone. The controller is further configured to receive information indicating the power delivered to the load zone and to cause the power delivered to the load zone to remain below the software-controlled power flow limit.
Claims20
An electrical power system comprising:
- a connection to a power source;
- two differential lines along which power from the power source travels to a load zone;
- a first energy storage unit;
- a second energy storage unit;
- a booster energy storage unit with one or more chemistries;
- one or more switches;
- and
- a controller configured to:
- configure the one or more switches to cause the first energy storage unit to be in series with the booster energy storage unit between the two differential lines;
- and
- based on a determination that a voltage drop across the first energy storage unit is less than a voltage drop across the second energy storage unit, configure the one or more switches to cause the second energy storage unit to be in series with the booster energy storage unit between the two differential lines.
An electrical power system comprising:
- a connection to a power source;
- two differential lines along which power is delivered from the power source to a load zone;
- a first energy storage unit;
- a second energy storage unit;
- one or more switches;
- and
- a controller configured to:
- configure, during a discharging phase, the one or more switches to cause the first energy storage unit to be in parallel with the second energy storage unit between the two differential lines;
- and
- based on a determination, during the discharging phase, that a voltage drop across the first energy storage unit or a voltage drop across the second energy storage unit is less than an acceptable voltage level, configure the one or more switches to cause the first energy storage unit to be in series with the second energy storage unit between the two differential lines.
An electrical power system comprising:
- a connection to a power source;
- two differential lines along which power is delivered from the power source to a load zone;
- a first energy storage unit;
- a second energy storage unit
- one or more switches;
- and
- a controller configured to:
- configure, during a charging phase, the one or more switches to cause the first energy storage unit to be in series with the second energy storage unit between the two differential lines;
- and
- based on a determination, during the charging phase, that a combined voltage drop across the first energy storage unit and the second energy storage unit is less than a threshold voltage level, configure the one or more switches to cause the first energy storage unit to be in parallel with the second energy storage unit between the two differential lines.
