摘要： 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. In the precharge mode, the first energy storage system charges the second energy storage system via the second DC/DC converter. In normal mode, the second energy storage is coupled to the electrical load via the second DC/DC converter.

摘要： 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.
