Abstract
An energy management system for optimizing low power and short term high power states of a power supply system. A significant feature of the present invention relates to a design of a power supply apparatus based on internal resistances of the power supply components. In an exemplary embodiment, the power supply supplies power for driving a load. The power supply includes a power source having a first internal resistance and includes a capacitor connected in parallel with the power supply and having a second internal resistance. The first internal resistance and the second internal resistance have a predetermined relationship.
Claims6
Apparatus for supplying power comprising:
- a power source;
- a capacitor connected in parallel with said power source;
- means for charging said capacitor to a voltage greater than or equal to said power source;
- a recharging means for recharging said power source stored;
- and
- a switch connected between said power source and said capacitor for blocking a recharging current of said recharging means from charging said power source, but allowing a current from said power source to charge said capacitor.
Apparatus for supplying power comprising:
- a power source having a first internal resistance;
- a capacitor connected in parallel with said power source and having a second internal resistance;
- and
- means for maintaining a voltage of said capacitor equal to a voltage of said power source, and for regulating current from said power source to maintain said current below a predetermined limit during a regenerative mode of operation.
Apparatus for supplying power to a load comprising:
- a power source;
- a capacitor connected in parallel with said power source;
- and
- a switch for selectively restricting regenerative charging current supplied to said power source relative to regenerative charging current supplied to said capacitor, to charge said capacitor to a voltage greater than said power source during a regenerative mode of operation.
