ZF unveils TempAI, an innovation aimed at enhancing the thermal management of electric vehicle motors.
ZF, a global leader in mobility technologies, has introduced TempAI, an advanced AI-based temperature management technology designed specifically for electric motors in electric vehicles (EVs). This innovative solution offers significant benefits and applications, enhancing the efficiency, sustainability, and reliability of EVs.
**Key Benefits:**
TempAI's self-learning temperature model improves internal motor temperature prediction accuracy by over 15%. This precise temperature insight is crucial as direct measurement inside the motor, particularly of components like the rotor, is extremely difficult. By enabling significantly more precise thermal utilization of the electric motor, TempAI allows up to 6% higher peak power output and measurable efficiency improvements in real-world driving cycles (WLTP). Under dynamic driving conditions like race circuits, the technology reduces energy consumption by 6 to 18% depending on load.
One of the key advantages of TempAI is its cost-effectiveness and rapid implementation. It requires minimal computing resources and works with existing vehicle control units, enabling cost-efficient integration into series production without additional hardware. Moreover, it accelerates development timelines from months to just a few days through AI-driven modeling.
**Applications:**
TempAI models and predicts thermal behaviour within electric motors during vehicle operation and testing, allowing engineers to push motors closer to their thermal limits safely. During motor development, TempAI analyses millions of data points from test benches and test vehicles to generate physics-based models automatically, allowing quick learning of complex internal motor thermal processes that are otherwise costly to measure.
The solution is production-ready and included in ZF’s new electrified powertrain platforms, such as the SELECT drive, supporting industry trends toward AI-driven powertrain optimization and software-defined vehicles.
Dr. Stefan Sicklinger, Head of AI, Digital Engineering, and Validation in R&D at ZF, stated that TempAI increases the efficiency and reliability of drives. He also highlighted that the development process offers substantial time savings, reducing durations from several months to merely a few days via AI-driven modeling.
TempAI demonstrates the potential of data-driven development to be faster, more sustainable, and more powerful. By optimizing thermal design with TempAI, the technology helps reduce the need for heavy rare earth materials, which are costly and environmentally challenging to source.
In conclusion, ZF's TempAI represents a technological breakthrough in EV electric motor temperature control, enabling higher power and efficiency without added sensors or hardware, all while reducing development time and environmental impact.
