UC Irvine study concludes intelligent PEV charging can minimize scale of stationary energy storage needed to meet renewable targets

October 24, 2016

A new study by a team at the University of California Irvine highlights the importance of intelligent plug-in vehicle (PEV) charging for minimizing the scale of infrastructure required to meet renewable utilization targets.

In the study, published in the Journal of Power Sources, the UC Irvine team examined how the intelligence of plug-in electric vehicle (PEV) integration impacted the required capacity of energy storage systems to meet renewable utilization targets for a large-scale energy system, using California as an example for meeting a 50% and 80% renewable portfolio standard (RPS) in 2030 and 2050.

SAE J2954 Wireless Charging on track to make decision for WPT 2 (7.7kW) in January; planned commercialization in 2020

October 13, 2016

In a program track on Charging Infrastructure at the World of Energy Solutions Conference in Stuttgart, Germany this week, Jesse Schneider (BMW), SAE Taskforce Chair, Wireless Power Transfer and Alignment Methodology, presented the recently published SAE TIR, Wireless Power Transfer (WPT) for Light-Duty Plug-In/ Electric Vehicles and Alignment Methodology (earlier post) along with plans for standardization by 2018 to support commercialization. The SAE TIR J2954 contains a normative specification for both the vehicle and infrastructure side coils for the power level WPT 1 up to 3.7kW and informative specifications for WPT 2 to 7.7kW.

The current timing plan projects a commercial rollout of Wireless Power Transfer infrastructure by 2020. The SAE J2954 Standardization plan includes coordinated bench and vehicle testing, industry consensus work (standards documents) and three milestones from 2016-2018 in support of commercialization of wireless power transfer.

2017 Mercedes-Benz S550e PHEV will offer wireless charging system built using Qualcomm Halo inventions

October 11, 2016

With the facelift of the Mercedes-Benz S550e plug-in hybrid in 2017, Daimler AG plans to launch a wireless electric vehicle charging (WEVC) system, manufactured by a Tier 1 power electronics supplier, which has licensed Qualcomm Halo inventions. The commercial application of WEVC will be a first among hybrid vehicles. Drivers of the S550e (badged S500 in Europe) equipped with the wireless charging option will simply park atop a special pad and charging will begin.

Qualcomm Halo uses high-power, resonant magnetic inductive wireless energy transfer and supports a relatively wide air gap between base charging unit (BCU) and vehicle charging unit (VCU). The charging pad’s multi-coil design (“Double “D” Quadrature”) delivers high energy-transfer efficiency and high power even if the pads are misaligned. The high degree of tolerance in both the vertical (z) and lateral (x,y) planes means drivers do not have to park accurately or need complex and expensive on-board alignment systems.

ELIX Wireless & Zongshen partner on wireless chargers for China and NA; Magneto-Dynamic Coupling (MDC)

September 21, 2016

ELIX Wireless, a Canada-based startup developing novel wireless power transfer technology, signed a strategic collaboration agreement with Chongqing Zongshen Power Machinery Co Ltd, a listed entity of the Zongshen Group. Zongshen Power also acted as the lead investor in ELIX’s US$5-million Series A funding round.

ELIX began as a spin-out from the University of British Columbia (UBC) in 2013 to commercialize its patented, Magneto-Dynamic Coupling (MDC) technology. ELIX MDC technology uses the interaction between magnetic fields to create a “remote magnetic gear” system with full 360-degree freedom of orientation. MDC operates at a frequency of 80-400 Hz, 1000 times lower than a resonant inductive system.

Columbus, Ohio wins $40M DOT Smart City Challenge; $10M more from Vulcan, $90M from private partners

June 24, 2016

US Transportation Secretary Anthony Foxx announced that Columbus, OH has been selected as the winner of the US Department of Transportation’s Smart City Challenge. (Earlier post.) As winner of the Challenge, Columbus will receive up to $40 million from US DOT and up to $10 million from Paul G. Allen’s Vulcan Inc. to supplement the $90 million that the city has already raised from other private partners to carry out its plan.

Using these resources, Columbus will work to reshape its transportation system to become part of a fully-integrated city that harnesses the power and potential of data, technology, and creativity to reimagine how people and goods move throughout their city.

INEES report shows intelligent integration of EVs reduces power fluctuations, but not currently economically viable

June 16, 2016

Partners Volkswagen AG, Lichtblick SE, SMA Solar Technology AG and the Fraunhofer Institute Wind Energy and Energy System Technology (IWES) have submitted the final report from the INEES research project (Intelligent integration of electric vehicles into the power grid for the provision of system services).

The findings of the report show that it is technically possible to absorb grid power fluctuations by connecting electric vehicles to the power supply. The research results will in future help to link electric mobility with the energy industry.

ORNL achieves 90% efficiency with 20 kW wireless charging for vehicles; looking ahead to 50 kW

March 31, 2016

A 20-kilowatt wireless charging system demonstrated at Department of Energy’s Oak Ridge National Laboratory has achieved 90 percent efficiency and at three times the rate of the plug-in systems commonly used for electric vehicles today.

ORNL’s power electronics team achieved this world’s first 20 kW wireless charging system for passenger cars by developing a unique architecture that included an ORNL-built inverter, isolation transformer, vehicle-side electronics and coupling technologies—all in less than three years. For the demonstration, researchers integrated the single-converter system into an electric Toyota RAV4 equipped with an additional 10 kWh battery.

Group of European electric bus manufacturers agrees on an open interface for charging

March 15, 2016

European bus manufacturers Irizar, Solaris, VDL and Volvo have agreed to ensure the interoperability of electric buses with charging infrastructure provided by ABB, Heliox and Siemens. The objective is to ensure an open interface between electric buses and charging infrastructure and to facilitate the introduction of electric bus systems in European cities.

Common, preferred interfaces will be opened up for all market participants and will be used for electric buses for opportunity charging (fast charging at end stops) and for overnight charging. The group is committed to contribute to European standardization activities and to share experiences with CEN/CENELEC and ISO/IEC in order to establish a common European standard for electric bus systems.

Cal Energy Commission awards $1.5M to Berkeley to advance open-source advanced smart charging technology; OpenVBOSS

February 11, 2016

The California Energy Commission is awarding the University of California, Berkeley $1.5 million to develop an advanced smart charging technology that maintains plug-in electric vehicle consumer needs while reducing charging loads, to achieve electricity grid benefits. The project will focus on controlling the charging of PEVs in residential and small commercial settings using a novel and flexible open-source, open-software architecture charge communication and control platform.

The proposed project addresses the problem of access and signals/controls for local data streams in order to control electricity systems loads for grid management. PEVs are proliferating in California under the Advanced Clean Cars Program, sometimes in geographic clusters; this is creating potential load management issues for electrical utility grids at the feeder and transformer level.
