German automotive technology giant Continental has developed a new sensor technology that is said to significantly enhance the efficiency and sustainability of electric vehicle (EV) motors.

For the first time, their new e-Motor Rotor Temperature Sensor (eRTS) directly measures the temperature inside permanently excited synchronous motors on the rotor itself.

This innovative approach delivers substantially more precise measurement results than current software-based temperature simulations, drastically reducing the tolerance range from 15deg Celsius to a mere 3deg Celsius. The enhanced accuracy offers a dual benefit for vehicle manufacturers: it enables them to reduce the reliance on costly rare earth elements used to boost magnet heat resistance and simultaneously improve potential motor performance. This, in turn, paves the way for greater sustainability in EV production.

The eRTS is a key development from Continental's E-Mobility Sensors (EMS) product centre, which is dedicated to creating advanced sensor technologies for electric vehicles.

Bin Huo, Head of Passive Safety and Sensorics (PSS) segment, Continental, said, "With less resource consumption and lower costs, eRTS sensor technology is advantageous over current solutions. This innovation shows that investing resources and focusing expertise in our product centre was absolutely the right decision. We will continue to successively expand our EV sensor portfolio."

Higher Measuring Accuracy

The eRTS system comprises two distinct components: a wireless mote temperature sensor unit positioned close to the magnet within the EV motor and a wired transducer element situated outside the motor, connected to the inverter control.

Rotors operate under extreme conditions, with temperatures potentially reaching up to 150deg Celsius. Consequently, precise monitoring and control of heat development in EV motors are paramount. Presently, heat development is not measured directly but is instead calculated based on data from the stator temperature sensor, phase current measurements and environmental variables. This indirect method results in a tolerance range of up to 15deg Celsius. To safeguard magnets from demagnetisation due to excessive heat, expensive rare earth elements are typically used to cover this entire tolerance range and ensure sufficient heat resistance.

The significantly greater measuring accuracy of the eRTS, which reduces the tolerance range to just 3deg Celsius, presents car manufacturers with new design possibilities and freedom in permanent magnet synchronous EV motors.

A considerable proportion of costly rare earth materials, which would otherwise be required to account for the wider tolerance range for safety reasons, can now be saved. Furthermore, the improved accuracy offers the intriguing prospect of enhancing motor performance by pushing the operational limits closer to the actual temperature threshold.

Christoph Busch, Lead – Product Centre, Continental, said, "Our E-Mobility Sensors product centre aims to increase efficiency and sustainability in electric vehicles. The eRTS technology is a prime example of this: reducing the use of rare earths contributes to a more sustainable supply chain, especially given that the number of EVs is expected to greatly increase in the coming years and decades. In combination with other sensor technologies, such as the e-Motor Rotor Position Sensor, it can even act as a system solution to create synergies that can save car manufacturers money and effort."

Ultrasound Technology

The eRTS's two components, the mote element and the transducer element, work in tandem. The mote temperature sensor unit measures the temperature directly at the target area, as close as possible to the magnet. Crucially, the wireless mote draws its energy solely from the wired transducer, which is connected to the Electronic Control Unit (ECU) and simultaneously provides the transducer with its measuring data. The transducer is located outside the EV motor on the chassis and transmits temperature information to the inverter control via a communication interface. Both the mote and transducer communicate using Piezo ultrasound, which also facilitates the energy supply to the mote.

Coretura, a 50:50 joint venture between Daimler Truck and Volvo Group, has entered into an engineering agreement with Accenture to accelerate the development of a software platform for commercial vehicles.

The company, headquartered in Gothenburg, Sweden, currently employs over 100 engineers. It continues to recruit specialists in system architecture, high-performance computing and cloud infrastructure to support its roadmap, which targets the delivery of its first commercialised products towards the end of the decade.

Coretura intends to create a single software platform, language and standard for trucks, buses and other heavy-duty transport vehicles. The platform is designed to support vehicle lifecycles of more than 15 years, moving the industry away from projects that require custom software development for each new vehicle.

As the engineering partner, Accenture will support development across several areas, including:

• Electrical and Electronic (E/E) architecture
• Software abstraction and hardware integration
• Embedded software, middleware, and cybersecurity
• Functional safety and cloud infrastructure

The platform aims to provide a reusable software stack to lower costs and standardise time-to-market for global manufacturers. For fleet operators, the system is designed to allow for continuous software updates and performance upgrades delivered over the air.

Johan Lunden, CEO, Coretura, said, “Our purpose is to advance mobility at the speed of ideas, and that takes depth. Building a full-stack SDV platform demands expertise across embedded software, middleware, cybersecurity, and functional safety, all designed for vehicles with lifecycles measured in decades. Accenture’s reinvention capabilities let us move faster without compromising the standards our customers depend on. This is acceleration, not course correction.”

Rainer Oder, SDV Embedded Software Lead, Accenture, added, “Helping the industry advance software-defined vehicles is a priority for Accenture. Our landmark collaboration with Coretura is designed to change embedded software engineering for automotive platforms. Together, we are looking to solve the challenges of a fully software-defined architecture – addressing critical areas such as hardware abstraction, API management and AI-based engineering optimisations.”

The ePlane Company has announced the completion of its full-scale electric vertical takeoff and landing (eVTOL) aircraft, the e200X. Designated PT-01, the prototype has successfully integrated all core subsystems into a single structure, marking the transition from design and simulation to physical testing.

The e200X is designed as a single airframe versatile enough to serve three distinct markets – Passenger Air Taxi, Urban Cargo Carrier and Air Ambulance.

The company emphasises that the aircraft was designed to be compact, allowing it to integrate into existing urban infrastructure without requiring significant city redesigns.

Developed at the company's own facilities in Chennai, the e200X features in-house development of major components, including propellers, airframe structure, landing gear and battery pack.

This vertical integration provides the company with control over performance, manufacturing costs, and iteration speed, having reached this milestone on approximately USD 21 million in funding.

With assembly complete, the e200X will now undergo ground testing, flight testing and certification.

Prof. Satya Chakravarthy, Founder, The ePlane Company, said, "We set out to build an electric aircraft to a world-class benchmark, engineered and manufactured in depth in India for the World.  We deliberately designed the e200X to be compact, because an aircraft that asks a city to rebuild itself around it will not solve the problem it was built to solve. The same airframe can move people as an air taxi, carry goods as a cargo aircraft, and save lives as an air ambulance, and it can do all three using the infrastructure cities already have. That combination of real capability and capital efficiency is how we intend to compete, and win, in markets around the world.”

The company’s board includes prominent figures such as Vishesh Rajaram (Speciale Invest), Eash Sundaram (JetBlue) and Aditya Ghosh (Homage, Akasa Air). The venture, incubated at IIT Madras, has also received international recognition, including being showcased at Bharat Innovates 2026 and featured in Nvidia Founder Jensen Huang’s GTC keynote.
