INL, auto companies complete bench tests on wireless charging systems

At INL’s Electric Vehicle Infrastructure Laboratory, researchers collaborated with six major companies to bench test wireless charging systems for electric vehicles.
Idaho National Laboratory researchers and six companies have achieved a major milestone by completing bench testing for wireless charging systems, a technology that eliminates the need to plug in electric vehicles.

INL researchers collaborated on the tests this past summer with Toyota, Nissan, WiTricity, Jaguar Land Rover, Qualcomm and one other auto company. The results were reported in November to SAE International (formerly known as the Society of Automotive Engineers) to support the SAE Technical Information Report J2954, a wireless charging guideline published earlier this year.

Wireless charging systems use electricity from the grid to generate a magnetic field from a charging pad on the ground that transfers energy to a pad on the bottom of the electric vehicle.  The energy is converted to electricity to charge the battery.

The SAE Technical Information Report J2954™ guideline is designed to allow charging pads from one company to work with the vehicle pads from another company. This “interoperability” is important for safety and performance of wireless charging systems.

“Electric vehicles equipped with a J2954 wireless charger should be able to charge over any J2954 charging pad,” said Richard “Barney” Carlson, the INL engineer who heads up the wireless charging tests.

When it comes to wireless charging, alignment with the ground pad matters. If the gap is too large, or the pads are misaligned, the charging efficiency is significantly reduced. At INL’s Electric Vehicle Infrastructure Laboratory, Carlson and his colleagues have developed a testing system to measure the efficiency of and electromagnetic field around the wireless charging systems.

A computer-controlled motor-driven table can precisely misalign the ground assembly relative to the vehicle assembly so researchers can determine how much energy is lost when cars aren’t perfectly parked. Then, different types of equipment are used to measure factors such as electromagnetic field strength, electrical power quality and charge power efficiency.

“This is the most comprehensive testing of its kind and will help the SAE committee develop the wireless charging guidelines,” Carlson said.

Engineers from the six companies visited the laboratory to collaborate on a series of interoperability tests for their respective wireless charging systems. Data from those tests will be used to further develop the draft SAE guidelines, which will ensure that wireless charging systems entering the market meet minimum interoperability requirements for proper functionality, high efficiency and safe operation.

“Idaho National Laboratory has provided SAE with invaluable bench data that the Technical Committee will use to develop the next phase of standardization,” said Jesse Schneider of BMW, chair of the SAE task force. “Wireless power transfer vehicle data is needed before guidelines can be published. INL offers an ideal combination of expertise and capabilities to assist industry with this effort.”

In addition to the convenience of hands-free charging, wireless charging systems could provide fail-safe vehicle charging for drivers who might occasionally forget to plug in their cars. Plugged in, electric vehicles can take anywhere from 30 minutes to eight hours to reach an 80 percent charge.

Funding for INL's wireless charging testing in support of SAE International comes from the Department of Energy’s Vehicle Technologies Office.

INL, Colorado company announce deal on battery monitoring technology

Eric Dufek, head of Idaho National Laboratory's Energy Stoarge Group, at work in the Energy Systems Laboratory on University Boulevard. INL has been involved with electric vehicle battery research for the U.S. Department of Energy since the 1980s.
The U.S. Department of Energy’s Idaho National Laboratory has teamed with Dynexus Technology of Boulder, Colo., to provide the energy storage industry with first-of-a-kind technology for advanced battery health diagnostics.

Under an exclusive licensing agreement, Dynexus will commercialize INL’s embedded wideband impedance technology for analyzing and forecasting the health, aging and safety characteristics of advanced energy storage devices. The 2011 R&D 100 Award-winning Impedance Measurement Box (IMB) was invented by INL’s Energy Storage Group with support from the DOE Office of Energy Efficiency and Renewable Energy’s Vehicle Technologies Office.

Dynexus, headquartered in Colorado, develops products and services that connect advanced sensor-based enterprise data with decision makers to improve access to embedded intelligence. The wideband impedance technique developed at INL delivers in-depth diagnostic insights not previously available outside the battery research lab, providing tremendous value for safer and more cost-effective commercial implementation of advanced energy storage technologies.

“The whole purpose of the work is to understand the bounds of safety and performance as the battery ages,” said Eric Dufek, INL’s energy storage group lead. “This allows informed decisions about the state of health and battery life.”

The dependability of energy storage devices, mainly batteries, is becoming increasingly important to consumers, industry and the military. As battery end-user expectations increase and the consequences of battery failures become more pronounced, there is a pressing need for timely insights about battery health to ensure predictable performance, personal safety and reduction of waste. INL’s broad-spectrum impedance technology enables embedded continuous monitoring of a battery’s health and remaining life throughout the entire course of its life cycle.

From an environmental standpoint, the INL technology could help find new uses for EV batteries after their capacity fades beyond acceptable power and range performance, usually defined as below 80 percent of initial capacity.

“This technology could help assess the resale value of a used electric vehicle, or provide remaining life and safety insights for repurposing those batteries into secondary applications,” said Dynexus president and CEO, David Sorum. “Monitoring battery health and remaining life will help ensure the safety and reliability of repurposed batteries, and will strengthen their viability, insurability and marketability.”

Although embedded wideband impedance evolved from INL’s participation in automotive battery research and development, Dynexus Technology will explore commercial applications across a broad range of markets, from EVs to drones, from utility energy storage to telecommunications, and from medical devices to military systems. In all cases, the wideband impedance technique delivers operational data not previously available outside a laboratory setting.

“The technology has the potential to add value at all levels across the battery value chain,” said David Lung, Dynexus chief technology officer. “It’s like having an onboard “smart meter” for your electric vehicle battery, providing the owner and the dealership with immediate and easily accessible factual information about battery health throughout its useful life.”

Home prices trend upward

Here is a line graph showing what the price of a $125,000 home in the Idaho Falls area would have done over the last 15 years. After peaking in the first half of 2008, the number slid in mid-2011 and bobbed for a few years, until mid-2014, when it started to climb again.
What a difference 15 years make, although it doesn’t always feel that way.

For lack of any real news breaking today, we decided to go back to our old friend, the Federal Housing Finance Agency House Price Calculator. This is the Web page where you can plug in your numbers and see how home prices have trended in your market.

Arbitrarily, we decided to see what a hypothetical property valued at $125,000 in the third quarter of 2001 would be estimated worth today. The results for all the markets we looked at are good, some really good. Here’s a breakdown.

Idaho Falls: $185,996  +48.7%
Pocatello: $185,252  +48.2%
Boise: $220,150  +76.1%
Reno: $209,754  +67.8%
Las Vegas: $181,459  +45.1%
Seattle: $251,652  +101.3%
Phoenix: $220,705 +76.5%

What’s interesting to look at is the volatility over the past 15 years. There's no question things bottomed out for everyone in 2011. In Las Vegas, your $125k from 10 years earlier would be $95,592 in the Q4 of 2011. In Idaho Falls, on the other hand, the line dipped but never below where it started. But the figure from Q3 of this year is still below the all-time high of Q3 2008, when it peaked at $187,961.

Here's a graph for Boise. Note that Joe Homeowner was underwater from Q1 2011 to Q2 2012, but recovery has been strong since then. 

Go ahead and try your house, but remember these are just numbers. Your house is only going to be worth what someone is willing to pay for it. What the HPI Calculator projects is what a given house purchased at a point in time would be worth today if it appreciated at the average appreciation rate of all homes in the area. The actual value of any house will depend on the neighborhood, house condition and age, home improvements made and needed, and many other factors. Consult a qualified real estate appraiser in your area to obtain a professional estimate of the current value of your home. Title XI of the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 requires that any appraisal used in connection with a federally related transaction must be performed by a competent individual whose professional conduct is subject to supervision and regulation. Appraisers must be licensed or certified according to state law.
