The 1kV Lithium-ion battery bank requires a high-power-density maintenance charger with ultra-low ripple charging capability to maximize battery life. This new technology will be able to supply ultra-low ripple charging power for all conditions while maintaining high efficiency. This system uses high bandwidth SiC MOSFET and soft-switching technology to substantially improve the Space, Weight, Power and Cost (SWaP-C). The charger can be integrated into an energy storage system or serve as standalone charger. Galley Power specializes in providing advanced solutions to Lithium-ion battery or battery packs including high voltage banks, 6T and BB2590 within the fields of battery management, 3-phase high efficiency bi-directional power conversion and optimize charging profile based on battery chemistry. Our goal is to integrate and transition this technology into Navy high voltage battery charging systems.
