China will scrap ownership limits on foreign automakers by 2022


Traffic in China

Since 1994, China has mandated foreign automakers to create joint-ventures with domestic companies to regulate ownership limits. The foreign companies have been limited to no more than 50 percent ownership. It's led to numerous tie-ups between established (MORE)

REPORTS AND STUDIES

Rethinking Transportation 2020-2030

Irem Kok, Sani Ye Zou, Joshua Gordon and Bernard Mercer

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.

SCIENTIFIC PAPERS

A A performance optimisation-based e-CVT design method and analysis of representative HEV/PHEV powertrains

Leon Zhou; Zuomin Dong
Int. J. of Electric and Hybrid Vehicles
2011 Vol.3, No.4 pp pp 318 – 339

An electronically controlled continuous variable transmission (e-CVT) which consists of planetary gears and electric machines plays a key role in advanced hybrid powertrains of HEV/PHEV/EREVs. Design of these e-CVTs for best performance is a challenging task due to the complexity of these e-CVTs and hybrid powertrain system derived from them. In this work, a performance modelling and optimisation-based design method is introduced to automatically identify the best performance of an e-CVT or other complex hybrid vehicle powertrain system. The complex design optimisation problem for peak powertrain performance is solved using a unique two-stage search method to significantly reduce needed computation and assure the accuracy of the optimisation. Four representative e-CVT powertrain designs of representative HEV/PHEV/EREVs were used as case studies. Test results are calibrated using verified data to reveal the performance characteristics and potential of each powertrain designs. Application of this method to pr oduce new e-CVT and gear-train designs with enhanced performance is demonstrated.

THESIS

PRIVACY-PRESERVING AUTHENTICATION AND BILLING FOR DYNAMIC CHARGING OF ELECTRIC VEHICLES

HONGYANG LI
University of Illinois, USA

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.
