Omega Seiki Mobility Partners With Exicom Tele-Systems

The powertrain business area of Continental, Vitesco Technologies, a leading supplier in the field of vehicle electrification, and ROHM Semiconductor, a leading company in SiC power semiconductors, have recently signed a development partnership, beginning in June 2020. Vitesco Technologies will use SiC components to further increase the efficiency of its power electronics for electric vehicles (EV). Through their higher efficiency SiC semiconductors make better use of the electric energy stored in a vehicle battery. Thus, an EV has a longer range, or the battery cost can be reduced without impacting the range.

“Energy efficiency is of paramount importance in an electric vehicle. As the traction battery is the only source of energy in the vehicle, any losses caused by power conversion need to be minimized. We are therefore developing a SiC option within our modular power electronics system," says Thomas Stierle, Executive Vice President of the Electrification Technology business unit at Vitesco Technologies. “To get the maximum efficiency out of the power electronics and the e-motor we will use SiC power devices from our preferred partner. ROHM has convinced us of its products”

“We are looking forward to the future cooperation with Vitesco Technologies”, says Dr. Kazuhide Ino, Corporate Officer, Director of Power Device business unit at ROHM Co.,Ltd “We are the leading company in SiC power semiconductors and have achieved a significant technological lead in this field along with the provision of power solutions combined with gate driver ICs. Together with Vitesco Technologies we want to further improve the energy efficiency of the electronic system in EVs to use the full potential of the SiC technology for a sustainable mobility.”

Squeezing out the best performance level by SiC
Vitesco Technologies is already developing and testing SiC technology in an 800-volt inverter concept to confirm the efficiency potential of the technology. The approach of this program is to look at the complete system of inverter and motor to identify the best combination of device technology and switching strategy.

In this context SiC semiconductors – e.g. SiC MOSFETs for 800-volt battery systems – offer more efficient switching in the inverter (higher frequency, steeper switching slopes) and cause fewer harmonic losses in the electric motor. Also, SiC technology is a key enabler for super-fast charging technology that uses 800 volts.

In the course of the cooperation ROHM and Vitesco Technologies will work on creating the optimum combination of ROHM’s SiC technology for high volume manufacturing and best fit of inverter design for highest efficiency.

“The SiC option is a very promising future part of our modular power electronics system comprising of software, power output stage, and switching strategy”, says Dr. Gerd Rösel, head of Innovation in the Electrification Technology business unit at Vitesco Technologies. “We will work with ROHM on an 800-volt SiC inverter solution as well as on a 400-volt SiC inverter solution.” Vitesco Technology plans the start of production of the first SiC inverter as of 2025, when the demand for SiC solutions is expected to rise significantly. “In other words, our partnership and development are perfectly on time”, says Rösel.

The preferred partnership will also be benefiting from short distances: Vitesco Technologies and ROHM both have sites at Nuremberg (ROHM Semiconductor Group: SiCrystal GmbH), which in turn is not far from Vitesco Technologies’ headquarters at Regensburg.

Honda Develops In-Motion Wireless EV Charging Technology For Public Road Trials In 2027

Honda Wireless Charging

Honda R&D, a subsidiary of Honda Motor Co., has developed underlying technology for a magnetic coupling wireless power transfer road system in partnership with Taisei Corporation and Taisei Rotec Corporation.

The system enables wireless in-motion charging for electric vehicles, including passenger cars and heavy commercial fleets. The partners plan to initiate demonstration testing on public roads starting in FY2027.

The technology integrates high-power-density receiver and transmitter units from Honda with a high-response direct current power supply system from Taisei and road-embedding construction techniques from Taisei Rotec. By supplying power to electric vehicles while in motion, dynamic wireless power transfer reduces the need for stationary charging infrastructure. The initial commercial focus targets logistics and transport operations, where continuous operation offers economic benefits.

The ground assembly embedded in the roadway combines the inverter and coil into a single unit designed to connect via direct current distribution. This design reduces component counts, simplifies wiring and supports installation into existing road surfaces through standard milling methods. The road pavement structures are engineered to withstand continuous traffic loads from vehicles weighing up to 20 tonnes (20,000kg).

Testing conducted at Taisei Group’s T-FIELD facility in Satte verified system stability and structural durability. Starting in late 2026, the companies will build a test roadway at T-FIELD Tamura to evaluate long-term durability under one million wheel-load cycles, measure power transfer efficiency at outputs up to 150 kW and analyse electromagnetic shielding.

The partnership will also join the Tateyama Expressway demonstration project managed by East Nippon Expressway Company starting in 2027.

Skoda Intros Hybrid Tech In Its Lineup With Octavia

Skoda Octavia Hybrid

Czech automaker Skoda Auto has expanded its powertrain portfolio with the introduction of a full hybrid powertrain for the Octavia, marking the first time the marque has offered this technology. The new powertrain is available for both hatchback and estate body styles in the Selection and Sportline trim levels.

The new Octavia utilises a series-parallel hybrid setup that combines a 1.5 TSI evo2 petrol engine with two electric motors, a single-speed automatic transmission and an automatic clutch that connects the engine directly to the front axle.

The smaller electric motor functions as a generator and starter, whilst the larger motor drives the front wheels and recovers energy during deceleration. The system automatically selects between all-electric, series hybrid, and parallel hybrid operation depending on speed, driver demand and battery charge levels. Electric mode offers a driving range of approximately two kilometres.

The model is offered in two power outputs: a 100 kW variant using a 96 kW petrol engine and a 125 kW version paired with a 110 kW engine. Both variants share identical electric motors and have an electronically limited top speed of 180 kmph. Energy is stored in a 1.6 kWh battery positioned beneath the rear seats, paired with a 40-litre fuel tank. Boot capacity is rated at 460 litres for the hatchback and 485 litres for the estate. Standard features include a 13-inch infotainment display and a 10-inch digital instrument panel. Orders open in October, with customer deliveries scheduled to begin in December 2026.

Johannes Neft, Chief Development Officer, Skoda Auto, said, "The Octavia is the first Skoda model to feature a full hybrid powertrain. Its series-parallel hybrid system combines a combustion engine with the flexibility of electric driving. Operating fully automatically, the system selects the most efficient drive mode according to the current conditions. The traction battery is recharged while driving by the combustion engine or through energy recuperation. With two output levels available for both the hatchback and estate, the full hybrid adds another technically versatile option to our powertrain portfolio giving customers even greater choice to match their individual needs."
