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.
