BroadBit completes its study on the integration of Electric Vehicles with Smart Metering systems

without comments

EV control over SmartGridWith the conclusion of the PowerUp research project, BroadBit has completed its research work share on the integration of Electric Vehicles with Smart Metering systems. The project results demonstrate a complete end-to-end integration of Electric Vehicle control through Smart Grid systems, based on applicable V2G (ISO/IEC 15118) and Smart Metering (DLMS/COSEM) protocol standards. BroadBit’s particular focus has been the research on integration between V2G and Smart Metering interfaces, as well as the interoperability testing of these systems. The project results are summarized in this conference publication.

Space propulsion publication

BroadBit-Space_PropulsionPre-print of an article submitted to the Astrophysics and Space Sciences Transactions journal:

We describe a solution for generating spacecraft on-board electricity in the megawatt power range. The introduced thermo-photovoltaic electricity generation works without magnets or external cooling; it combines operational simplicity with a good power per mass ratio.

Once in orbit, the system shall be capable of powering numerous missions within the inner solar system or a single long range mission.

Space exploration today is limited by the length of time and amount of fuel required for reaching desired destinations. An ideal propulsion design simultaneously features high Isp, high thrust power, and limited engine weight. Recent advances in nano-scale fabrication open up new possibilities for thermo-photovoltaic electricity generator design, and allow a the use of high-trust electric propulsion technologies. High-powered on-board electricity generation is key to reducing travel times to nearby planets and to the the expansion of space exploration horizons. The following sections describe each component of the proposed on-board electricity generator. …

Vehicular communication publications

without comments

publicationsResource Sharing Principles for Vehicular Communications
This paper proposes a suitable scalability principle for each major vehicular communication scenario: periodic safety broadcasts, event-driven safety broadcasts, and unicast message forwarding. Each scenario section investigates an appropriate design of individual congestion control tools for the implementation of related scalability principle.

Estimation of Channel Utilization at the Beaconing Edge
Estimating channel utilization at beaconing edge is important, so that power control feedback can be based on comparing this utilization rate to a target level. The beaconing edge channel utilization estimate presented in the ‘Resource Sharing Principles for Vehicular Communications’ paper is revised with the following aspects;
– taking an estimate of link asymmetry into account,
– interpolating on link attenuation metric instead of distance metric.

GeoMapped Timing of Beacons and Unicast Messages
This paper proposes a timing algorithm for assignment of beacon transmissions. The proposed geographically derived beacon timer solves the problem of ‘hidden-terminal’ packet collisions for periodic broadcasts and certain unicast messages, regardless of particular road network topology details.
