Abstract: A battery fleet charging system for charging two or more battery packs simultaneously, at independently controlled charge rates. The present invention can intelligently distribute the available charge power among multiple batteries, either symmetrically or asymmetrically, as specified by a controller that specifies and regulates the charge voltage.

Abstract: An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

Abstract: A computer-implemented system for an exercise machine includes a mechanical energy storage device and an apparatus configured to supplement the resistance of the mechanical energy storage device with an added resistance and dissipate the energy of the mechanical energy storage device and an associated athlete. A communication pathway enables the exercise machine to communicate with at least one additional associated exercise machine to duplicate the total resistance in the exercise machine to an associated exercise machine. A central server includes a processor, memory, and a networking interface. A first user device includes a display, a processor, a memory, and a networking interface. The central server receives data from the exercise machine, extracts synchronization performance information from the data, and transmits the synchronization performance data to the first user device where it is used to train an athlete for an athletic endeavor.
