ST. LOUIS – Researchers from Missouri S&T along with their industry partners recently demonstrated new battery charging technology to the U.S. Department of Energy that could eventually accelerate the time it takes for electric vehicles (EVs) to be fully charged and back on the road.

The demonstration was held last month in Bitrode Corp.’s St. Louis facilities.

“Charging electric vehicles has become faster over the years, but it still takes more time than most people would prefer,” says Dr. Jonathan Kimball, the Fred W. Finley Distinguished Professor and chair of electrical and computer engineering at Missouri S&T. “Our project aimed to address this issue by developing new charging technology that could one day be more readily available and significantly speed up the charging process.”

During the demonstration, the researchers successfully showed how large amounts of electricity could be transferred to an EV’s battery at a high rate without the power grid collapsing.

“This charger is capable of handling one megawatt, or one million watts, of electricity,” Kimball says. “That is a substantial amount of power, and we successfully demonstrated how this technology can support it and be used for extreme-fast charging .”

To develop this charging technology, the researchers created an algorithm to maximize the potential charge rate, while also reducing lithium plating, which is a reaction that has previously stood in the way of faster energy transfers.

The team also developed a power converter to connect the energy grid with three vehicles and a stationary battery. The stationary battery’s purpose is to take some of the load off the grid when vehicles use the charger. For another aspect of the project, the team also designed a grid interface algorithm to manage the power demands as efficiently as possible.

The initial aim of this multi-year project was to develop a charging system that could operate at 12 kilovolts, but this was later scaled to 480 volts. However, Kimball says the project still explored the same basic issues, and the team made significant progress toward developing a system that could one day charge EV batteries in about 10 minutes.

Cyril Narishkin, president and CEO of Bitrode, says his company was honored to be involved in this project and work toward charging electric vehicle batteries more expeditiously. 

“This type of collaboration between private businesses and researchers from public universities can lead to some amazing results and make the world better for everyone,” he says. “It was fantastic to work closely with multiple partners toward this common goal.”

Bitrode’s primary objective for the project was to develop and build the actual charger that was used. LG Energy Solution constructed battery packs with advanced thermal management features capable of accepting the extreme charge currents used for this project and provided S&T with additional resources. Ameren provided advisory information and studied how the electricity usage would impact the power grid.

S&T faculty members on the team included Dr. Rui Bo, S&T assistant professor of electrical and computer engineering; Dr. Jonghyun Park, associate professor of mechanical engineering; Dr. Mehdi Ferdowsi, Schlumberger Endowed Professor in Electrical and Computer Engineering and associate dean for research for the College of Engineering and Computing; and Dr. Pourya Shamsi, associate professor of electrical and computer engineering. Dr. Robert Landers, a former S&T Curators’ Distinguished Professor of mechanical and aerospace engineering, was previously on the research team before taking a new position at University of Notre Dame.

This project received $2.9 million in funding from the DOE. Missouri S&T received $1.8 million from the DOE and provided the same amount in matching funds. The three corporate partners received a total of $1.1 million and provided equal matching funds as well.

Project partner LG Energy Solution designed, manufactured and validated an 800V vehicle prototype battery pack capable of repeated 350kW extreme charge (XFC) events. The company also provided an energy storage system (ESS) utilized by the XFC station to meet other grid robustness project requirements. The final prototype battery solution included a novel cold plate that incorporated sufficient heat rejection capability, transferring the large amount of heat generated during extreme fast charging to the coolant medium. To accomplish this, LG Energy Solution utilized a non-traditional welding approach, known as friction stir welding, during cold plate fabrication. Additionally, they provided battery cells and battery modules to allow the S&T research team to evaluate the optimal battery charge profile at the cell, module and pack levels.d pack levels.

    I recently replied to a different article from this website regarding federal funding. It is beginning to appear that the entire university is employed by the federal government to confirm it’s own bias. As a taxpayer I telling the you and anyone else there that you should be ashamed of yourselves for taking taxpayer dollars when this country’s federal debt is beyond repayment. Here is my response to the other article:

    While I can appreciate technological advancement I don’t appreciate paying for it as a taxpayer especially when it’s in the venue of ‘climate change’. When espoused with the words ‘smaller carbon footprint’ I can’t help but believe the benefactors of this grant have chosen to forget that carbon, the most common element on the planet, is not harmful in an of it’s own existence. The value of our money is being debased before our eyes yet this university chooses to announce it has bilked the taxpayer our of $5 million USD chasing misguided ‘climate change’ solutions.

    Our federal government employs roughly 1 million people through federal grant system. With a $32 Trillion USD debt coupled with an annual deficit of $2 Trillion…and climbing…this taxpayer is inclined to recommend and insist the entire university grant system be abolished until our federal debt issues are resolved. Economics will no doubt dictate this sooner or later.

    In the future I would much prefer to hear about privately-funded research that was directed towards real issues and problems as opposed to those contrived by the ‘climate-change’ cult.

    This is fascinating and explained so well in this article. My question is, how are we going to safely dispose of all these batteries going forward? And how does the disposal of batteries help our environment?

  • Great to read your article, Greg!
    If this has not already happened, please work with the Missouri S&T public affairs office and request they prepare and send different types of PR releases to various types of media, i.e. TV, radio, newspapers, Tesla, Popular Science, etc. This is revolutionary news and should be used to publicize Missouri S+T!
    This is news that can be used to help publicize Missouri S& T on both a national and international level.
    It should appear in both national and international publications, such as the Wall Street Journal, as well as Popular Science and various other newspapers and magazines.
