“Electromagnetic induction to power an EV?”
At first, it might sound a little far-fetched.
But what if this once-imaginary concept is now being actually implemented inside an EV system?
Today, we sat down with an engineer who deciphers the flow of electricity
within a highly complex EV powertrain system—and finds possibility amidst layers of variables.
A journey that began in the lab is now rolling onto real roads.
Shall we dive into this story of technology and transformation?
DAMI
Hi there! Thanks for joining us today. Could you start by briefly introducing yourself?
Engineer DEOMATO
Hello!
I'm DEOMATO, an engineer in charge of the data analysis and simulation part at DEOGAM.
DAMI
Great to meet you, DEOMATO!
Thank you for making the time—let's get started. :)
When you first heard you’d be developing a real product
using electromagnetic induction, what was your initial reaction?
Engineer DEOMATO
“Is this really going to work?”
Back in college, I once did a small experiment with wireless power transfer using a tiny circuit.
The efficiency was so poor—it was a real struggle.
And now, we’re trying to apply that same concept to a much larger and more complex system like an EV.
So honestly, my first thought was, “Is this realistically even possible?”
DAMI
That makes a lot of sense.
If your early experiences were that challenging, doubt probably came before hope.
So, moving from theory to reality—what did you find most challenging about this project?
Engineer DEOMATO
An EV powertrain is a tangled beast.
You’ve got the battery, inverter, motor—all these components interacting.
Then factor in all the variables that shift depending on driving conditions...
The hardest part is
identifying and predicting all these nonlinear elements, then incorporating them into the system design.
DAMI
Sounds like complexity at its peak.
And yet you kept pushing forward with experiments.
Was there a moment when you finally felt, “Yes—this is really going to work!”?
Engineer DEOMATO
We conducted rigorous theoretical reviews and simulations for the HRC design,
along with multiple performance and certification tests.
At first, the results didn’t meet our expectations.
But through repeated refinements and analysis, we eventually saw a meaningful power output.
That’s when I thought, “This is really going to work!”
DAMI
That must’ve been incredibly rewarding—to see clear results after so much persistence.
Let me ask: what was the biggest technical hurdle you had to overcome?
Engineer DEOMATO
Most theories on electromagnetic induction assume static conditions and a single frequency.
But that’s not how EVs behave in real life.
Their operating frequency constantly changes during driving,
so we needed a design that accounted for those dynamic conditions.
That difference is what sets our work apart from traditional magnetic energy harvesting—and
it’s what made it such a tough challenge.
DAMI
I had no idea frequency alone could open up such complexity.
Let’s talk tools—how do you plan to use Maxwell in this process?
Engineer DEOMATO
The biggest benefit is reducing the time and cost of real-world testing.
We’re working to simulate the entire EV drivetrain—including the inverter, HRC, and motor—within Maxwell.
It’s not possible to fully replicate reality, but if we can get high fidelity, we can replace a lot of physical testing.
That would mean faster development and huge savings in time and money.
DAMI
That's the true power of simulation—efficiency without compromising on insight.
How will this Maxwell-based model help you collaborate with external partners or companies?
Engineer DEOMATO
If the simulation platform is well-implemented,
we can present clear, quantitative data on how our product performs.
We can even input the exact inverter or motor that a client uses,
then analyze how our HRC responds and performs.
This allows for faster optimization tailored to client needs—and
improves collaboration with partners overall.

DAMI
So it's more than a technical tool—it’s also a communication bridge.
What kind of testing environments are you currently modeling?
Engineer DEOMATO
We’re modeling based on official driving profiles like UDDS and HWFET,
using a chassis dynamometer environment.
We're basing our setups on real vehicles used in validation tests,
such as the Hyundai IONIQ 5 and the BYD T4K.
We also incorporate components commonly found in EVs, like
three-phase inverters and permanent magnet synchronous motors.
DAMI
Grounding it in real-world use cases must really help bridge the gap between simulation and reality.
Looking ahead, where do you see this technology expanding in the future?
Engineer DEOMATO
As long as the structure allows for electromagnetic induction, the possibilities are endless.
For example, electric buses and ships deal with much higher power and
greater electromagnetic losses—HRC could make a big impact there.
And if we succeed in miniaturizing the HRC,
we could even apply it to drones and micromobility devices.
DAMI
The potential here is huge!
What’s something you personally hope to achieve with this technology?
Engineer DEOMATO
I want to realize electromagnetic induction within highly complex systems like EVs.
And beyond that, I’d love to apply the unique properties of magnetic
materials to create even more refined and advanced EM systems.
DAMI
It’s already an impressive breakthrough, but I can’t wait to see how far it evolves!
Now for a fun one—what’s one message you’d like to share with future users of this tech?
Engineer DEOMATO
“If you use it, you’ll go farther!”
DAMI
(Laughs) Straightforward and powerful—I love it.
Lastly, what kind of engineer do you think you’ll be three years from now?
Engineer DEOMATO
A cool tomato?! (laughs)
“Cool Tomato” isn’t just a silly nickname—it actually means a lot to me.
In the kids’ song, the tomato isn’t perfectly shaped or typical.
But instead of trying to be like everyone else, it dances to its own rhythm.
There’s something strong and cheerful about that, and I want to bring that same spirit to my work.
As a power analysis engineer, the hardest part has always been the gap between models and reality.
It’s a constant challenge to extract meaningful patterns from all the variables.
Sometimes doubt outweighed confidence.
But through consistent analysis and hands-on testing,
I’m learning to predict and respond faster—and more accurately.
I want to be the kind of person who makes complex technology approachable,
who finds harmony in uncertainty,
who stays cheerful—but serious when facing a problem.
That’s what being a Cool Tomato means to me.
And that’s the kind of engineer I hope to become. 😊
Turning electromagnetic induction from theory to product hasn’t been a simple path.
But perhaps it was that unwavering belief—that this could actually work—that powered the journey forward.
We're excited to see how far this technology will grow,
and who it will connect with along the way.
We hope today’s interview
helped you see not just the tech, but the person behind it.
From real-world challenges in the field to a growth story shaping the future of energy —
we’ll be back with the story of <Engineer Ha-WHY> on July 30.👉
