Infineon Launches PSOC 4 HVPA-SPM 1.0 – Bringing Intelligence to Automotive Battery Management Systems to Enable Zonal Architectures

­Infineon Technologies AG introduces the PSOC™ 4 HVPA-SPM 1.0, an advanced microcontroller designed for high-voltage Li-ion battery management in electric vehicles (xEVs). The microcontroller combines precision, safety, and programmability, while supporting zonal architectures and the transition to Software-Defined Vehicles (SDVs). To maximize its impact, Infineon is partnering with Munich Electrification, a leading provider of innovative battery management software. Together, they deliver advanced and cost-efficient Battery Management System (BMS) solutions that accelerate development and reduce costs. 

The PSOC 4 HVPA-SPM 1.0 offers a fully integrated design with key features that bring advanced intelligence, safety, and efficiency to BMS. It provides high-precision monitoring of current, voltage, and temperature, ensuring reliable battery performance and improving the accuracy of State-of-Charge (SoC) and State-of-Health (SoH). Fully compliant with ASIL D (ISO 26262) safety standards, the microcontroller ensures robust and reliable operation in critical high-voltage battery systems. Its built-in Arm® Cortex®-M0+ processor delivers advanced edge intelligence, enabling faster data processing and reducing the load on the central Electronic Control Unit (ECU). This supports zonal architectures and allows OEMs to customize the system for specific requirements, leading to shorter development cycles and faster time-to-market.

“The PSOC 4 HVPA-SPM 1.0 represents a significant leap forward in high-voltage battery management, combining precision, intelligence, and safety for next-generation electric vehicles,” said Ralf Koedel, Vice President of Automotive Microcontrollers at Infineon. “The positive feedback from our first customers reinforces its value in enabling innovative and reliable solutions for electrified mobility”.

Building on the launch of the PSOC 4 HVPA-SPM 1.0, Infineon is partnering with Munich Electrification to deliver the “Smart Edge BMS Software” for smarter and more efficient BMS. The collaboration leverages Infineon’s semiconductor technology and Munich Electrification’s software expertise. Munich Electrification brings advanced know-how in battery management software and system optimization to the partnership, ensuring seamless integration and enhanced functionality. This innovative system reduces costs and complexity while enabling faster and safer development of next-generation electric vehicles. It helps OEMs efficiently meet regulatory requirements and support the global shift toward sustainable electric mobility.

“We are extremely excited to contribute with our deep BMS and software expertise to the next level of cutting-edge technology in this partnership with the global leader in automotive semiconductors,” said Dr. Uwe Wiedemann, Managing Director of Munich Electrification.

Teaming up with Munich Electrification is another example of Infineon’s Drive Core Strategy in action. In this strategy, Infineon combines its advanced semiconductor technologies with Drive Core software bundles, developed to simplify and accelerate automotive software development in collaboration with automotive ecosystem partners.
