Abstract: A multi-source energy storage system, it includes a first energy storage system, a second energy storage system, and a second DC/DC converter and controller and a method for supplying power to an electrical load from multiple energy storage systems. The first energy storage system can be coupled to an electrical load. The second DC/DC converter and controller can be coupled between at least one of the following: a second energy storage system and a first energy storage system or electrical load. The controller settings control the first and second energy storage systems and the second DC/DC converter runs in both precharge mode and normal mode.

Abstract: It is a system for supplying power to at least one load. The system comprises at least one power source, load bank and control device coupled to the at least one load. The load bank is coupled to at least one power source and at least one load. The load bank comprises a controllable voltage source, at least three resistors coupled between an output side of the controllable voltage source and the at least one power source, and at least one storage element. The controllable voltage source comprises more than one switches. And the at least one storage element comprises one or more capacitors, batteries, or combinations thereof. The control device is configured for controlling the switches during a first condition such that, to the extent that an output power of the at least one power source exceeds a requisite power of the at least one load, any excess output power is either supplied to the at least one storage element or consumed by the at least three resistors. This invention also provides a method for supplying power to at least one load.

Abstract: An apparatus includes at least one energy source and a drive system coupled to the at least one energy source. The drive system converts electrical power received from the at least one energy source and provides converted electrical power for driving at least one load. The drive system includes a first converter, a second converter, and a first switch module coupled to outputs of the first and second converters. When the apparatus is operating under a first mode, the first switch module is switched to assume a first state to allow a first output electrical power provided from the first converter and a second output electrical power provided from the second converter to be combined for driving a first load with the combined output electrical power.
