The analysis in this report is based on detailed evaluation of data on the market, consumer and regulatory dynamics that work together to drive disruption. We present an economic analysis based on existing technologies that have well-known cost curves and on existing business-model innovations. We extrapolate data where we have credible knowledge that these cost curves will continue in the near future. The disruptions we highlight might happen more quickly due to the acceleration of the cost curves (such as has been happening in lithium-ion batteries, for example) or because of step changes in these technologies (such as has been happening in solid-state batteries and artificial-intelligence processing units). New business-model innovations may also accelerate disruption.
Understanding parasitic energy costs for PHEV conversion packs as we move toward V2G

Building practical plug-in electric vehicles is under way at many car companies around the world, though it is expected that they will not be widely available in the USA for quite some time. The ultimate vehicle cost is controlled substantially by the battery storage capacity required and this, in turn, is governed by the vehicle size and performance expected by consumers. The present paper examines the specific situation where existing hybrid vehicles might be converted to plug-in functionality by adding a supplementary battery pack to extend the driving range while keeping the electric/gasoline hybrid drive-train intact. We examine fuel efficiency from the standpoint of vehicle weight to extract system parameters that quantify the extra fuel consumption associated with driving a slightly heavier vehicle after plug-in conversion has been effected. We show that only modest additional battery capacity is required to meet most commuter needs in a cost-effective manner.

PRIVACY-PRESERVING AUTHENTICATION AND BILLING FOR DYNAMIC CHARGING OF ELECTRIC VEHICLES
Dynamic charging of electric vehicles (EVs) is a promising technology for
future electrified transportation. By installing wireless charging pads under
the roadbed, dynamic charging allows EVs to charge their batteries while
moving through magnetic induction between the wireless charging pad and
the receiving coil attached to the EV’s battery. A pre-requisite for dynamic
charging in practice is the support of cyber infrastructure and protocols. Although
many research efforts aim to increase the charging efficiency and remove
the physical barriers of dynamic charging, protocols in the cyber space
that support dynamic charging is still lacking, especially protocols for digital
authentication and billing. Due to EV’s high mobility, location privacy is
also an important research issue. In this thesis we present three protocols:
FADEC, Portunes, and Janus, that together provide privacy-preserving authentication
and billing framework for dynamic charging of EVs. The protocols
are tailored towards the dynamic charging scenario to reduce real-time
computation and communication overhead, and uses modern cryptography
building blocks to preserve the EV’s location privacy. Simulation results
and implementations indicate that the presented protocols are efficient and
feasible for future dynamic charging applications.
