Abstract: This application is directed to a battery protection system including a sense resistor, a comparator, a switching component, and a protection integrated circuit (PIC). The sense resistor is electrically coupled in series with one of a plurality of rechargeable battery cells that are coupled in parallel in a battery. The comparator is coupled to the sense resistor and configured to compare a voltage drop across the sense resistor with a reference voltage to determine whether a subset of the rechargeable battery cells is not charging in the battery. The switching component is coupled to the battery, while the PIC is coupled to the comparator and the switching component. The PIC is configured to control charging and discharging of the battery including disabling the battery from being charged in accordance with a determination that a subset of the rechargeable battery cells is not charging in the battery.

Abstract: The present document describes systems and techniques for battery management and optimization using voice integration systems. These techniques include one or more electronic devices defining a voice integration system and having connectivity to a server system. These devices are configured to provide audio data relating to battery operations, including battery charging, to a user of an electronic device. Further, these techniques enable the user of the electronic device to provide additional audio data to the voice integration system and, thereby, instruct the server system to perform one or more actions relating to battery operations associated with the electronic device. In this way, the user can manage and optimize battery operations using the voice integration system.
