Abstract
An apparatus and method arbitrates bidirectional optical communication across optical link ends of independent controller area network buses. A mobile device has a battery management system and a first controller area network bus having a first optical link end, and a charging station has a second controller area network bus having a second optical link end. When the mobile device aligns with the charging station for charging, the optical links ends align to allow communication between the battery management system and the charging station regarding charging the battery. The arbiter apparatus is operationally interposed between the optical link ends and arbitrates the bidirectional communication by delaying a subsequent communication from one of the battery management system and the charging station until a dominant bit of a prior communication is released, thereby preventing the controller area network buses from transmitting simultaneously across the optical link ends.
