Infineon Technologies AG and Eatron Technologies have partnered to bring advanced machine learning solutions and algorithms to the AURIX TC4x MCU. The partnership is aimed at advancing automotive BMS. Thanks to the state-of-the-art machine learning capabilities of the MCU family with integrated PPU, Eatron can maximise the performance and accuracy of its AI-powered battery management software.
Together, the two companies are helping EV manufacturers solve three technological challenges that have hindered increasing customer adoption of EVs: range anxiety, charging speed and battery health.
“Infineon’s AURIX TC4x PPU enables us to offer AI-based battery diagnostics, including lithium plating detection, as well as prognostics, such as state of health (SoH) and ageing trajectory, and remaining useful life (RUL) prediction at the edge,” said Umut Genc, CEO of Eatron. “Coupled with our market-leading state-of-everything (SoX) solution, which provides the most accurate and robust cell-level estimation of available charge, power, and battery health, this gives users of the TC4x the opportunity to have the leading BMS solution enabled by our software and machine learning models.”
The PPU, an on-chip single instruction, multiple data (SIMD) vector DSP, significantly reduces computation time compared to traditional CPUs. For ease of use, Infineon provides an automated toolchain within its ecosystem to provide the most convenient and efficient handling of the PPU. For example, an automated toolchain enables customers to convert existing models into vectorised code automatically.
“Our new AURIX TC4x family is designed to improve the efficiency of many xEV applications. Today, we are proud to announce that AURIX TC4x overcomes previous limitations in computing performance, enabling our customers to fully exploit the value of high-precision models and algorithms,” said Thomas Boehm, senior vice president and general manager, Microcontroller Automotive at Infineon. “The next level of technological advancement in electromobility is now also gaining momentum in BMS. And in addition to providing outstanding hardware, we are pleased to welcome partners like Eatron to serve this market together.”
