Die 2-Stufen-Motor-Technologie von Hyundai Motor Group ist ein wegweisender Schritt in der Elektromobilität. Sie ermöglicht eine präzise Balance aus Alltagstauglichkeit und Hochleistungs-Performance – bislang ein scheinbarer Widerspruch. Herzstück des Systems ist ein neuartiger Dual-Inverter-Aufbau mit 12 Leistungshalbleitern in einem „6 plus 6“-Design. Diese Kombination aus Silizium- (Si) und Siliziumkarbid-Schaltern (SiC) erhöht die an den Motor lieferbare Spannung um bis zu 70 % und erlaubt so mehr Leistung bei gleichbleibender Effizienz.

Dank intelligenter Softwarealgorithmen wechselt das System je nach Fahrsituation zwischen einem Ein- und Zwei-Inverter-Modus: Im Stadtverkehr wird maximale Energieeffizienz erzielt, bei voller Beschleunigung steht sofort die volle Power zur Verfügung. Die Technologie kommt bereits in Modellen wie dem Hyundai IONIQ 5 N, IONIQ 6 N, NEXO FCEV und Kia EV6 GT zum Einsatz.

Trotz der erhöhten Komplexität bleibt die Bauweise erstaunlich kompakt. Möglich wird dies durch inhouse entwickelte Power-Module, die Kühlung, Gewicht und Platzbedarf optimieren. Die Kühlung erfolgt über ein doppelseitiges System, das die Wärme effizienter ableitet – ein entscheidender Punkt bei hoher Dauerbelastung.

Mit dieser Technologie setzt Hyundai neue Maßstäbe: nicht nur in Sachen Leistung, sondern auch in puncto Effizienz, Nachhaltigkeit und Serienreife. Kein Wunder also, dass das System mit dem „Presidential Award“ bei den Korea Technology Awards 2024 ausgezeichnet wurde.

00:00High Efficiency in Everyday Driving

00:05Instantaneous High Power when Accelerating

00:08That's the kind of EV we dream of

00:11Made possible by the balance of power, efficiency and lasting performance

00:17A challenge no one solved

00:19Until Hyundai Motor Group did with their new Motor Drive System

00:22Let's take a closer look

00:24Sure, sounds great

00:26Electric vehicles don't just move with a motor alone

00:29The Motor Drive System consists of three key parts

00:32The motor, reducer and inverter

00:35The motor generates torque

00:38The reducer transfers that torquer to the wheels

00:41And the inverter, the conductor of the system

00:44Converts the battery's DC power into AC power for the motor

00:48Precisely controlling how and when that power is used

00:51How does it control power exactly?

00:54The inverter consists of semiconductor-based switches

00:57When the switches are closed, current flows

01:00When they're open, it doesn't

01:03Depending on the rhythm and pattern of the switches

01:07The motor rotates and moves the vehicle forward

01:10When AC current flows through the motor's coils

01:14It creates a magnetic field that constantly changes as the current alternates

01:19This shifting magnetic field pushes and pulls the magnetized rotor at the motor's center

01:24Causing it to spin

01:26Wow, so that's how an EV moves

01:29Now, let's talk about power

01:32The power output is determined by voltage and current

01:35To increase the drive motor's power

01:38You can increase the battery voltage or adjust the motor's characteristics to increase current

01:43Usually, it's the latter

01:45But increasing current makes the motor drive system larger and heavier

01:50And heat management becomes more difficult

01:53Also, when designed mainly for high power output

01:57Efficiency drops significantly during everyday city driving

02:01So, how are these limitations solved?

02:05That's where the inverter plays a crucial role

02:07While it doesn't increase battery voltage itself

02:10The way it applies and controls that voltage greatly affects the power

02:14And, we developed an innovative system that expands this usable voltage range

02:21By increasing voltage utilization

02:23Conventional inverters use six switches

02:27Often employing silicon carbide semiconductors

02:30A high-efficiency but costly material

02:33We added six silicon switches

02:36Creating a total of 12 switches in our new system

02:39As a result, the voltage that can be applied to the motor increased by about 70%

02:45How exactly was the voltage range expanded?

02:48By doubling the number of inverter switches connected to a single motor

02:52We were able to apply higher voltage levels

02:54In regular driving, only the silicon carbide switch set is used to maintain high efficiency

03:00In high-speed or high-output power conditions, both switch sets operate together

03:05Is doubling the number of switches really that significant?

03:09It's more than just adding parts

03:11It's a fundamental transformation of the entire control system architecture

03:15When more switches are added, a completely new level of coordination between them becomes necessary

03:21Like two riders on a tandem bicycle who must pedal in perfect sync to move forward

03:27A conventional six-switch inverter divides them into upper and lower sets for three phases

03:32Operating in eight different combinations under strict switching rules

03:37So, what happens when the number of switches doubles?

03:39The combinations increase eightfold, requiring much more precise control

03:44To move precisely, the key must be how the flow of electricity is controlled, right?

03:49Exactly! If you visualize the six-switch combinations as a hexagonal voltage space vector

03:55The maximum voltage that can be applied to the motor equals one side of that hexagon

04:00Now imagine moving a voltage vector along that line

04:04If it moves in steps, how would the car feel?

04:07Uh, like it's jerking or stuttering

04:10Right! That's why advanced control to smooth the voltage vectors is so important

04:16While six-switch control is common, Hyundai Motor Group devised a system that controls

04:2212 switches simultaneously, expanding the usable voltage space

04:27One module fixes six switches in a six-step configuration, while the other controls the remaining six through 64 possible combinations

04:36To manage these two voltage spaces flexibly, Hyundai Motor Group introduced a transfer switch

04:42that shifts to the optimal state depending on driving conditions

04:46So, the car can respond freely depending on the situation?

04:50Precisely! The transfer switch's precise control allows smooth mode transitions, providing

04:57strong power during acceleration and high efficiency during regular and long-distance driving

05:03Saying the whole system was rebuilt from scratch wasn't an exaggeration

05:07It's not just about increasing numbers

05:09It's about orchestrating 12 switches to operate as one through an advanced control strategy

05:15But with all this complexity, doesn't the system get bigger or heavier?

05:19Normally yes, but we solved the size and weight issue with our own in-house designed power modules

05:25The inverter's size depends on its built-in semiconductor power modules

05:30By integrating nine modules into three, we created a simpler structure

05:34And improved cooling from single-sided to double-sided

05:40Thanks to these step-by-step optimizations, we achieved a high-performance yet compact inverter design

05:47Wow! I didn't realize EV motor systems were this advanced!

05:51This is only the beginning

05:54The technology will expand to more vehicle types and soon it will be on roads everywhere

06:00As EVs become part of everyday life, Hyundai Motor Group continues to shape the standards of tomorrow
