Energy storage and control system for a vehicle electrified drivetrain
First Claim
1. A system for supplying electrical energy to a partial or a total electrified drivetrain of a vehicle, the system comprising:
- an energy storage system having an energy storage system output, the energy storage system output having voltage in excess of a operating voltage of the electrified drivetrain;
a first converter having an input coupled to the energy storage system output and a first converter output, the first converter output being at the operating voltage of the electrified drivetrain;
a supplemental storage bank having an input coupled to the first converter output and a storage bank output, the storage bank output comprising the first converter output combined with a supplemental operating current; and
a second converter having an input coupled to the storage bank output and a second converter output, the second converter output being at the operating voltage of the electrified drivetrain and at a peak operating current of the electrified drivetrain.

Abstract
A system for supplying electrical energy to a partial or a total electrified drivetrain of a vehicle, the system may include an energy storage system having an energy storage system output that is excess of an operating voltage of the electrified drivetrain. A first converter having an input coupled to the energy storage system output and a first converter output that is at an operating voltage of the electrified drivetrain. Optionally, a supplemental storage bank may be coupled to the first converter output. A second converter is coupled to the supplemental storage bank to provide an output at an operating voltage of the electrified drivetrain and at a peak operating current of the electrified drivetrain.
