Continental’s New Sensor Tech Measures Heat In EV Motors, Claims To Reduce Rare Earths To Protect Magnet

Continental EV sensor

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.

MathWorks, a leading software tools company, recently concluded MATLAB EXPO 2026 today, hosting over 1,300 engineers, scientists and industry leaders to discuss the transition of generative AI, engineering copilots and agentic AI from experimental phases to production-scale deployment.

The event focused on the integration of AI-assisted design and simulation into Model-Based Design workflows across industries such as automotive, aerospace and semiconductors. Discussions highlighted the importance of maintaining engineering rigour, traceability and safety while utilising automated workflows.

At the event, MathWorks leaders Seth Deland and Avinash Nehemiah demonstrated how agentic AI capabilities in MATLAB and Simulink are accelerating simulation-led decision-making and system deployment.

Savyasachi Srinivas, VP at Collins Aerospace, detailed the use of AI-enabled knowledge systems and digital twins to move aerospace products from initial concept through to formal certification.

The event saw a panel discussion featuring representatives from Boeing, Mercedes-Benz R&D India, TCS, HSBC and the Indian Institute of Science addressing the critical need for human oversight and verification when validating AI-assisted outputs in real-world systems.

Also, the event saw technology demonstration including Raftar Formula Racing from IIT Madras, displayed their competition-winning race car designed using MathWorks tools.

The highlight at the UAV Pavilion saw drone and eVTOL (electric Vertical Take-Off and Landing) platforms from Speedgoat, Zmotion Autonomous Systems and Reude Technologies.

Sunil Motwani, Country Manager – Sales and Service – MathWorks India, said, “This year’s MATLAB EXPO reflected growing industry interest in applying GenAI, copilots and agentic AI to engineering workflows in ways that improve productivity while preserving validation, traceability and safety.”

The conference underscored a consistent industry shift: engineering teams are moving beyond basic AI experimentation toward certification-ready systems where AI agents accelerate design and verification while keeping engineers central to the decision-making process.

Olectra Greentech Adopts Dassault Systemes’ 3DEXPERIENCE Platform For EV Development

India Gets First LiDAR-Based No-Stop Tolling On National Highways

Cron AI - senseEDGE

India has officially commenced its transition to barrier-less tolling with the live deployment of Multi-Lane Free Flow (MLFF) infrastructure at Manoharpur, Rajasthan and Hyderabad, Telangana.

The initiative is powered by Cron AI’s 3D perception platform, senseEDGE, which allows vehicles to pass through tolling points at highway speeds without stopping.

The deployment, a partnership between the National Highways Authority of India (NHAI) and Cron AI, uses LiDAR-based real-time detection to identify and classify vehicles. Unlike traditional toll plazas, the MLFF gantries capture vehicle dimensions and axle counts to determine toll classes while simultaneously using ANPR for number plate recognition and linking to FASTag RFID accounts.

The system currently handles 30,000 to 35,000 vehicles per day at the initial sites. It is designed specifically for Indian road conditions, the platform manages inconsistent lane discipline and ‘occlusion’ (overlapping traffic) with zero false classifications. The LiDAR technology remains accurate during poor visibility, glare, darkness and high-speed traffic.

Tushar Chhabra, Founder & CEO, Cron AI, said, “India is moving from tolling as a checkpoint to tolling as an invisible layer of national infrastructure. That shift requires the road itself to become intelligent. That is what senseEDGE is built to do, and what is now live on some of India’s busiest corridors.”

The move aligns with the Government of India’s mandate to transition over 1,100 toll plazas to MLFF systems. With the National Highway network expanding to 146,204 km as of March 2025 and FASTag penetration reaching 98 percent, the objective is to eliminate idling, reduce fuel consumption, and lower emissions at tolling points.
