1. A vehicle charging system for a hybrid electric vehicle, the vehicle charging system comprising:
a connection system coupleable to an external charging source, the connection system configured to utilize a first connection and a second connection;
a plurality of DC converters on-board the vehicle and coupleable to the connection system, the plurality of DC converters configured to operate in combination to step up and step down an input voltage derived from the external charging source;
an energy storage device coupleable to at least one of the plurality of DC converters; and
a controller programmed to:
charge the energy storage device at a first charging rate when the energy storage device is coupled to the first connection;
charge the energy storage device at a second charging rate when the energy storage device is coupled to the second connection; and
operate the plurality of DC converters when charging the energy storage device by:
operating a first DC converter to boost the input voltage to an intermediate voltage; and
operating a second DC converter to buck the intermediate voltage to an output voltage to charge the energy storage device.
