High power bidirectional charging systems with a split battery architecture are disclosed. The bidirectional charging systems can include a bidirectional charger and an integrated battery. The bidirectional charger is bidirectional, providing vehicle-to-grid (V2G) energy transfer capability from an electrical grid to an electric vehicle (EV), as well as electrical energy transfer capability from the integrated battery to the power grid and from EV battery to the electrical grid. The integrated battery is split into two sections. A first battery section is a lower voltage battery, which can feed the output direct current (DC) directly without a converter. A second battery section is a higher voltage battery. The output power provided by the charger can exceed voltage limits of the individual electronic components by adding the output of the first integrated battery section with an output of the second integrated battery section.

Methods and apparatus for controlling frame timing and/or duration in a wireless communications network are described. Recurring interference is monitored for, detected and evaluated. Frame structure to be used in the network is determined based on the detected recurring interference in one or more monitored frequency bands. An implemented frame structure is changed dynamically in response to a detected new pattern of interference. Uplink and downlink timing and frame duration maybe determined separately, e.g., based on interference which affects uplink and downlink communications, respectively. Devices, e.g., base stations, may independently determine frame start times and durations based on detected interference or may communicate with one another to reach a consensus on a frame start time and duration to be used by multiple base stations. Downlink frame start times and durations may be based on interference information reported by one or more devices, e.g., mobile user equipment devices.
