Marine Portable Power Unit

A conceptual design of a battery charging station with UPS back-up capability was completed under contract M67854-C-6509. The resulting system can charge up to twelve BB-2590 batteries at the maximum charging current (to minimize charging time) and provide 1000 Watts of back-up power (both AC and DC outputs are provided) for at least one hour. Individual batteries can be hot-swapped for field use in other equipment without interrupting the on-line UPS capability. The system accepts both universal AC and external DC power inputs, allowing use with worldwide power grids, portable generators, and automotive alternators. The system will implement Acumentrics’ field-proven environmentally ruggedized mechanical design and thermal management technology to ensure performance in potentially harsh environments. The objective of this proposal is to complete a detailed design of the conceptual system defined during the Phase I effort. All subsystems will be tested both individually and in a brassboard system configuration prior to completion of the system detailed design. Four prototype systems will be built and tested to ensure all power and functional requirements have been met. Two systems will then be delivered to the sponsor for end-user evaluation and two will be subjected to shock, vibration, environmental and EMI/EMC tests.
