MULTI-SOURCE ENERGY STORAGE SYSTEM AND ENERGY MANAGEMENT AND CONTROL METHOD

摘要

This invention is 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. 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. This invention is a method for supplying power to an electrical load from multiple energy storage systems.
