Abstract
Techniques are described for implementing automated control systems that each control or otherwise manipulate, for a target system having one or more battery cells each having internal components that include one or more internal supercapacitor components in parallel with at least one battery component, usage operations for one of the internal components of one of the battery cells, with the usage operations for the internal components of a particular battery cell being synchronized or otherwise coordinated to protect the battery component(s) of the battery cell while satisfying other criteria (e.g., to increase battery cell life and/or reduce power dissipation). In at least some situations, the target system is an electric vehicle, and the automated control systems control the electric vehicle's battery cells to provide electrical power to the motor during acceleration and constant speed driving, and to store electrical power in the battery cells during braking or other deceleration.
