Apparatus and method for rapidly charging an electric vehicle
First Claim
1. An energy storage and management system (ESMS) comprising:
- one or more energy storage devices configured to store electrical energy;
a power electronic conversion system having a plurality of energy ports, the power electronic conversion system comprising a plurality of DC electrical converters; and
a controller configured to;
split a source current flowing from an electrical source that is connected to one of the plurality of energy ports into a first current and a second current, wherein the first current flows through a first of the plurality of DC converters and the second current flows through a second of the plurality of DC converters;
alter the first current and the second current by selectively turning on and turning off current flow to the first and second DC converters; and
form a charging current by passing the first current and the second current simultaneously to a first of the one or more energy storage devices that is coupled to a second of the plurality of energy ports.

9. A method of managing an energy storage and management system (ESMS) comprising:
-
coupling a current source to a first port of the ESMS; coupling a first energy storage device to a second port of the ESMS; providing a source current to the ESMS from the current source; splitting the source current into a first current at a first voltage and a second current at the first voltage; directing the first current to a first DC voltage converter of the ESMS; directing the second current to a second DC voltage converter of the ESMS; boosting the first voltage of the first current to a second voltage to form a first modified current by selectively turning on and turning off the first DC voltage converter; boosting the first voltage of the second current to the second voltage to form a second modified current by selectively turning on and turning off the second DC voltage converter; and combining the first modified current with the second modified current to provide a charging current to the first energy storage device at the second voltage. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory computer readable storage medium positioned on an energy storage and management system (ESMS) and having stored thereon a computer program comprising instructions which when executed by a computer cause the computer to:
-
split a source current flowing from a first electrical source that is connected to a first of a plurality of energy ports into a first current and a second current, wherein the first current flows through a first of a plurality of DC converters and the second current flows through a second of the plurality of DC converters; interleave operation of the first and second DC converters such that each of the first and second DC converters boosts from a first voltage to a second voltage; and form a charging current by passing the first current and the second current simultaneously and at the second voltage to a first of one or more energy storage devices that is coupled to a second of the plurality of energy ports. - View Dependent Claims (16, 17, 18, 19, 20)
