Electric Vehicles Connecting the 5.9 GHz V2X and Smart Grid Domains

Andras Kovacs, Zoltan Jako

Over the past decade, 5.9GHz cooperative systems have been developed for automotive applications. A major challenge in implementing large-scale vehicle-to-infrastructure communication technology lies in the effort and costs of deploying the necessary 5.9GHz road-side communication units. One straightforward solution involves utilizing electric vehicles plugged in for recharging (or even public recharging stations) as roadside communications units, which maintain broadband connectivity with the infrastructure through the smart grid network. By realizing this idea, it will be possible to maintain vehicle connectivity without the need for a dedicated subscription from a 3G network operator while eliminating roaming issues.
