AbstractNot Available The project will utilize Electro Energy's bipolar nickel-metal hydride (Ni-MH) battery technology, miniaturized power electronics and different photovoltaic (PV) technologies to introduce a novel integrated power cell (IPC) for space and remote terrestrial power applications. The calculated power density is 17 W/kg - - more than three time the state-of-the-art for the combined weight of the PV array, power electronics and battery subsystems. EEI's patented, low cost bipolar Ni-MH wafer cell and plastic bonded electrodes are unique in their ability to be produced as a thin, large area energy storage device necessary to optimize the IPC concept. As such EEI's wafer cell technology is ideally suited to be assembled directly to the PV cells as a weight and cost saving design. The PV technologies investigated will include conventional, high efficiency crystalline silicon cells, amorphous silicon cells and newer copper-indium-diselenide (CIS) thin film technology. A conventional power circuit will be used to control the charge and discharge of the IPC. Miniaturized power electronics will be selected and an experimental circuit will be developed for testing the integrated power cell and controlling the end-of-charge. An experimental IPC will be produced for laboratory testing on a low-earth-orbit test regime. Electrical and thermal performance data shall be collected using an automated test and data acquisition system.
