Proxy mobile IPv6 for electric vehicle charging service: Use cases and analysis

It is widely acknowledged that the key limitation to a raising market deployment of Electric Vehicles (EV) is correlated to the anxiety related to electric vehicle charging services (EVCS). From a user perspective, the electricity service should provide widely available and easily reachable charging stations with transparent payment options. From electricity operator perspective, charging vehicles should be well scheduled in time and space to avoid sudden burst of requests. Such EVCS should be conducted before reaching a charging station as well as ubiquitous and transparent to the mobility of EVs. An efficient heterogeneous communication system is then required. The centralized nature of the EVCS makes a network-based IP mobility such as PMIPv6 a good choice, first to make
heterogeneous technologies transparent to the EVCS, but also hides the mobility of the EVs to the service. In this paper, we first present the mapping between the charging type and use
cases of the EVCS. We then describe the required extensions to PMIPv6 to be integrated to the EVCS, and finally via a near-toreal testbed show that the EVCS satisfies the data delivery time required by the IEEE 1646.
