Abstract: A battery-charging system configured to charge a battery of a device to a nominal voltage includes a load-detection circuit, memory storing controller-executable instructions, and a controller configured to execute the instructions, which cause the controller to detect a load coupled to the battery above a first threshold load using the load-detection circuit, and control the battery-charging circuit to charge the battery to a high voltage in response to detecting the load above the first threshold load, wherein the high voltage is above the nominal voltage. The controller can be configured to execute other instructions, such as outputting a notification that the battery is being charged to a high voltage and/or controlling the battery-charging circuit to discharge the battery in response to detecting a reduced load or a user command.

Abstract: Examples of the disclosure include a battery system comprising an output configured to provide output power to a load, one or more battery cells configured to store electrical energy to provide to the load, and a battery management system configured to receive one or more operational parameters of the battery system, determine whether the one or more operational parameters are less than at least one operational-parameter threshold, modify a discharge threshold of the one or more battery cells responsive to determining that the one or more operational parameters are less than the at least one operational-parameter threshold, and control the battery system to be in a battery-optimization mode responsive to determining that a discharge level of the one or more battery cells is below the discharge threshold.
