APPARATUS AND METHOD FOR CHARGING AN ELECTRIC VEHICLE
First Claim
1. An energy storage and management system (ESMS) comprising:
- one or more energy storage devices coupled to a power device and 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, each DC electrical converter configured to step up and to step down a DC voltage, wherein;
each of the plurality of energy ports is coupleable to each of the one or more energy storage devices; and
each of the plurality of energy ports is coupleable to an electrical charging system; and
a controller configured to;
determine a first condition of a first energy storage device and a second condition of a second energy storage device, wherein the first and second energy storage devices are each connected to respective energy ports of the power conversion system;
determine a power split factor based on the first condition and on the second condition; and
regulate power to the first and second energy storage devices based on the power split factor.
