Abstract: A storage system provides electrical power for driving a vehicle. The storage system has a first and a second storage module for storing electrical energy. The storage system includes a switching unit which is configured for connecting the first storage module and the second storage module in series for a charging operation and in parallel for driving the vehicle. The storage system includes a control unit which is configured to implement measures in order to reduce a difference between a state of charge of the first storage module and a state of charge of the second storage module in preparation for a parallel connection of the first storage module to the second storage module.

Abstract: Methods and apparatus of improving telecommunication network efficiency by increasing user device registration with and use of the network are disclosed. Improved user device registration and use, and thus increased efficiency may be achieved by allocating revenue generated by operation of a telecommunication network between user devices, a network operator device, and a third party device. The allocation of revenue may be based, at least in part, on a hierarchical relationship between user devices registered with the network and information concerning the use of the telecommunication network by the user devices.

Abstract: Methods and apparatus of determining and communicating end user credit for an account associated with a telecommunications network based on delivery of advertising content to telecommunication devices associated with the end user and hierarchically related telecommunication devices are disclosed. The end user credit may be based, at least in part, on a hierarchical relationship between telecommunication devices associated with multiple end users of the network, as well as information concerning the delivery of advertising content over the telecommunication network to the devices associated with the end users.
