Infineon’s new PSOC 4 integrates local processing for advanced EV battery management
Infineon Technologies AG has launched the PSOC 4 HVPA-SPM 1.0, a new automotive-grade microcontroller designed to bring greater intelligence, precision, and safety to high-voltage Li-ion battery management in electric vehicles. With support for emerging zonal architectures and the shift toward Software-Defined Vehicles (SDV), the device aims to streamline EV system development while improving performance and efficiency.
In the race toward SDVs, how can automotive OEMs decentralize BMS intelligence to accelerate development timelines and unlock greater performance flexibility at the battery edge? For eeNews Europe readers interested in EV power systems, this release underscores an important trend: integrating more intelligence at the battery edge to reduce system complexity and better support next-generation vehicle architectures.
Bringing intelligence to the battery edge
The PSOC 4 HVPA-SPM 1.0 integrates high-precision current, voltage, and temperature monitoring to deliver more accurate State-of-Charge (SoC) and State-of-Health (SoH) calculations. Fully compliant with ASIL D (ISO 26262), the microcontroller is built for the safety-critical environment of xEV high-voltage battery packs. Its Arm® Cortex®-M0+ core provides fast local processing of battery parameters, easing computational demands on the central ECU and helping OEMs architect smarter zonal designs.
Infineon seems to position this edge-intelligent approach as a way to cut development time while enabling greater system flexibility. By distributing intelligence throughout the battery domain, automakers can fine-tune performance, safety strategies, and signal processing without reworking central software stacks. For developers navigating increasingly tight time-to-market pressures, this level of programmability and precision stands to be a notable advantage.
Partnership with Munich Electrification
To accelerate adoption, Infineon is pairing the microcontroller with Munich Electrification’s Smart Edge BMS Software. The collaboration aims to deliver a unified, cost-efficient BMS platform that merges Infineon’s semiconductor hardware with Munich Electrification’s software expertise.
According to the announcement, “Teaming up with Munich Electrification is another example of Infineon’s Drive Core Strategy in action.” As part of this strategy, Infineon notes that it integrates its semiconductor portfolio with Drive Core software bundles co-developed with ecosystem partners to simplify automotive software development.
Munich Electrification contributes deep domain knowledge in battery management algorithms, system optimization, and integration workflows, enabling automakers to more easily meet regulatory targets and accelerate EV development. The joint solution is expected to reduce system complexity, enhance functional safety, and support the global transition toward sustainable electric mobility.
