    Abstract: Because a rechargeable battery has an increased number of uses (e.g., cycles), the battery's internal impedance can increase and the efficiency of the battery can become degraded. This internal resistance can cause cutoff voltage thresholds and cutoff current thresholds to prematurely stop a phase of battery charging, as these cutoff values can be based on low-cycle count batteries. New cutoff values can, instead, be based on battery impedance. Use of an adjusted cutoff current threshold during a constant voltage cycle can increase the capacity of high-cycle count batteries. Use of an adjusted cutoff voltage threshold in step charging can increase the charging speed of high-cycle count batteries. These increases in efficiency by using adjusted cutoff values can increase as the battery is further high-cycle count, in comparison with low-cycle count cutoff values used with high-cycle count batteries.

    Abstract: A power-regulating charger is an apparatus used to manage the flow of electrical power to the battery of a mobile computing device. To accomplish this, the power-regulating charger includes an electrical plug, an output terminal, a shutoff switch, a microcontroller, and a wireless communication module. The electrical plug is a male connection terminal used to connect the power-regulating charger to an external power supply. The output terminal is an electrical terminal used to transfer power from the power-regulating charger into the connected mobile computing device. The shutoff switch is electrically connected between the electrical plug and the output terminal and is used to open the circuit between these two components. The microcontroller is a processing device that directs the shutoff switch to enable or inhibit the transfer of power. The wireless communication module receives commands that are wirelessly transmitted to the power-regulating charger from the mobile computing device.
