How Hyundai Motor Group’s advances in electrification are redefining efficiency and effectivity
Electrical automobiles are remodeling the best way we transfer, however what defines a really nice EV expertise? Prospects at this time count on thrilling efficiency and effectivity – and Hyundai Motor Group’s superior motor expertise delivers precisely that.
Hyundai Motor’s IONIQ 5 N and Kia’s EV6 GT show that EVs can have interaction drivers in methods we’ve not seen earlier than, balancing this with distinctive every-day usability and refinement. The expertise behind this mix of attributes, broadening the working window of the Group’s EVs, is innovation in movement.
On this article, we’ll discover Hyundai Motor Group’s 2-Stage Motor System intimately, explaining how this award-winning expertise delivers each supercar-level efficiency and distinctive power effectivity – one thing that, up till now, has been thought-about unattainable.
What Makes Hyundai’s 2-Stage Motor System a World EV Recreation-Changer?
On the coronary heart of this method are three important elements:
- The inverter – converts DC energy from the battery into AC energy for the motor
- The motor – generates rotational drive
- The reducer – transfers this drive to the wheels
Increasing Voltage Utilization
An EV’s energy output is dependent upon the voltage and present the battery can ship to the motor (or motors) through the inverter. Historically, rising present resulted in heavier propulsion techniques and higher warmth administration challenges. Motor techniques optimized for prime output on this approach usually compromise effectivity throughout on a regular basis driving, however Hyundai Motor Group’s R&D improvements have overcome this problem by rethinking the inverter.
The two-Stage Motor System includes a twin inverter construction outfitted with 12 semiconductor switches in a “6 plus 6” configuration, doubling the traditional depend. One set of six switches makes use of silicon carbide (SiC) semiconductors for prime effectivity, whereas the opposite set makes use of silicon (Si) semiconductors to help high-power circumstances.
This configuration will increase the voltage that may be equipped to the motor by as much as 70 p.c, enabling the next energy output with out compromising effectivity.
The system operates intelligently based mostly on Hyundai Motor Group’s good dual-mode management, cut up throughout the next circumstances:
- Metropolis driving – makes use of a single set of switches for optimum effectivity
- Excessive efficiency – prompts each units of switches to ship most energy
Superior Management Structure
Hyundai Motor Group developed proprietary management algorithms to make sure seamless transitions between these two modes.
Doubling the variety of switches was not only a {hardware} improve – it required a whole redesign of the management system. A standard six-switch inverter operates in eight combos, however with 12 switches, the combos multiply eightfold, demanding way more exact coordination and management.
The proprietary algorithms handle this complexity, smoothing voltage transitions and delivering seamless, uninterrupted and highly effective efficiency. The system makes use of a switch swap to shift seamlessly between modes, making certain robust energy when accelerating and excessive effectivity throughout long-distance driving.
Compact and Excessive-Efficiency Design
Regardless of the added complexity, the inverter stays compact because of Hyundai Motor Group’s in-house energy module design. Every module homes the ability semiconductor switches and offers packaging that ensures warmth dissipation and electrical insulation.
To realize a smaller, lighter inverter, Hyundai Motor Group built-in 9 modules into three, decreasing measurement and weight whereas sustaining sturdiness. The cooling system was additionally enhanced with a double-sided setup, considerably bettering warmth dissipation. This enhancement permits for increased energy density inside a smaller package deal, enabling excessive output with out rising general dimensions. These optimizations imply the 2-Stage Motor System delivers cutting-edge functionality whereas remaining sensible for mass manufacturing.
Why Hyundai Motor Group’s 2-Stage Motor System Improvements Matter
This 2-Stage Motor System is the one setup of its form to attain each excessive efficiency and effectivity – this expertise represents a serious leap ahead in EV engineering, delivering thrilling driving experiences with out compromising sustainability.
This innovation earned the Presidential Award on the 2024 Korea Know-how Awards, the nation’s highest honor for technological excellence – underscoring Hyundai Motor Group’s management in EV innovation.
The two-Stage Motor System is already powering high-performance EVs, such because the Hyundai IONIQ 5 N, IONIQ 6 N, IONIQ 9, and the all-new NEXO FCEV, in addition to the Kia EV6 GT, EV9, and EV9 GT, setting a brand new benchmark for electrical mobility worldwide.
Hyundai Motor Group goals to make superior EV expertise extra accessible and clear – serving to clients recognize the engineering that powers their driving expertise. As electrical mobility continues to evolve, improvements like this 2-Stage Motor System will stay central to delivering each pleasure and effectivity, reinforcing the Group’s dedication to shaping a better, extra sustainable future.
