A DC-AC converter includes a DC-DC converter providing bi-directional conversion between a first DC power signal and a second DC power signal, the first DC power signal being on a first DC bus and the second DC power signal being on a second DC bus. The DC-AC converter also includes an inverter providing bi-directional DC-AC conversion between a third DC power signal and a first AC power signals the third DC power signal being on the second DC bus and the first AC power signal being on a first AC bus.

An integrated power conditioning unit includes a DC bus, a first terminal for connection to first AC equipment, a second terminal for connection to second AC equipment, a first inverter circuit providing bi-directional AC-DC conversion between a first AC power signal and a first DC power signal, and a converter assembly providing bi-directional AC-DC conversion between a second AC power signal and a second DC power signal. A control module controls the first inverter circuit such that the first DC power signal may flow from/to the DC bus and the first AC power signal may flow from/to the first terminal. The control module also controls the converter assembly such that the second AC signal power signal may flow from/to the second terminal and the second DC power signal may flow from/to the DC bus.

摘要:
Systems and methods for controlling a hybrid power architecture to provide fuel or energy savings. Recharge time of an energy storage device (ESD) is reduced through the application of a controlled potential and ESD recharge time management over the life of the hybrid system through manipulation of the ESD charge state window of operation. Fuel or energy savings is achieved by controlling the partial-state-of-charge (PSOC) window of the ESD based on a recharge resistance profile of the ESD and by controlling a charging potential applied to the ESD based on a recharge current and/or the estimated recharge resistance profile of the ESD.
摘要:
Systems and methods of controlling a dispatch operation of an energy storage system are provided. In particular, a degradation value of a present dispatch state of an energy storage system can be determined. The present dispatch state can specify one or more energy storage units presently coupled to the system. The degradation value can be determined based at least in part on one or more operating parameters, such as temperature, open circuit voltage, charge or discharge current, and/or contactor life. The degradation value can then be compared against one or more degradation values associated with one or more candidate dispatch states. A dispatch state can then be selected based on the comparison. One or more energy storage units can be selectively coupled to the energy storage system based at least in part on the selected dispatch state.
