Abstract

A rechargeable multipurpose power management system has a power management system that can include a plurality of power management units. The power management units sources can be individually activated and deactivated (I think there might be a confusion between power sources and the system. Everything is within one box itself (the image that I sent you). Each unit is a power management system that can be connected to a variety of INPUT power sources. Several power management units can be combined together to create a stack of them but each one can operated individually as well). and each one is configured to be coupled to a variety of inputs. A rechargeable battery is coupled to the (One rechargeable battery is attached to only one power management units). A charging controller provides regulated charging to the battery. A plurality of convertors are (do we need to specify here what kind of converters, like DC-DC converters) coupled to the battery and provide output voltages that are accessible individually. A plurality of sensing circuits sense external signals and provide selective activation or deactivation of the system.
