Abstract
A control system for charge and output control of a rechargeable thin film microbattery cell comprises a charge control logic component configured to control the level of charge of a thin film microbattery cell, a battery cut-off logic component to cease current draw on the thin battery thin film microbattery cell under predetermined conditions, a mode control logic component operably coupled to the charge control logic component and the battery cut-off logic component to enable operation of the charge control logic component and the battery cut-off logic component under predetermined conditions, and a Switch Capacitor DC-DC Downconverter Component for delivery of voltage external to the system configured to reduce battery output voltage potential by a factor of at least 2:1. Systems operably connected to a rechargeable thin film microbattery cell and powered devices comprising the system and the microbattery cell are also described.
