Design and implementation of a power packet network protocol for flexible power routing

Abstract

A power packet dispatching system and power packet routers with the power storages have been developed. The system is expected to reduce the number of wires, to provide energy on demand and to be applied to various system working with battery such as electric vehicles, robots and so on. In the previous studies, when a router receives a power packet, it is temporarily charged to the storage and immediately transferred to another router or a load. In this paper, we propose more flexible routing protocol for power packet dispatching systems. We have designed a novel protocol with several commands to operate the routers, to charge power to a storage of a router, to reproduce power packets using the charged power, and so on. We have implemented the proposed protocol on the power packet routers and shown that our protocol can transmit the power packets flexibly.
