In a world where the demand for electric vehicles is only climbing, the most important component of a functional EV is the battery, and making the battery last as long as possible is the number one priority of many companies. Named one of Clarivate’s Top 100 Global Innovators of 2025, STMicroelectronics offers a comprehensive suite of automotive-grade solutions designed to balance performance, safety, and long-term sustainability in modern electric powertrains.
Precision Powertrain Control for Hybrid Platforms
The SPC56/57 automotive microcontrollers, paired with the L9177A engine control IC, provide highly accurate control over fuel injection, spark ignition, and exhaust after-treatment—key functions in achieving compliance with today’s stringent emissions standards. This high-integration solution is ideal for hybrid vehicles, helping OEMs bridge high performance with environmental responsibility while accelerating the electrification of conventional powertrains.
Smarter Battery Management for Safer, Longer-Lasting EVs
ST’s Battery Management System (BMS), centered around the L9963E battery monitoring and balancing IC and the L9963T isolated transceiver, is built for advanced safety and efficiency. Combined with ST’s 32-bit MCUs, power management ICs, VIPower smart switches, protection devices, and EEPROMs, this ASIL-compliant platform provides:
By supporting up to 14 battery cells and scalable daisy-chain communication, the L9963E also enables flexible implementation in high-voltage battery systems (48V and above), while delivering low-EMI, long-distance, and reliable data transfer via transformer-isolated interfaces.
High-Efficiency Traction Inverters: Unlocking Full Motor Performance
The traction inverter converts energy from the battery to drive motors in the drivetrain. This impacts the vehicle's road performance, driving range, and reliability. Key factors include the inverter's weight and size. Inverters need to be able to handle the intense heat and vibration that they are subject to due to the automotive environment. Some energy is lost during the exchange. A more efficient traction inverter means more of the battery charge is usable. To help OEMs and system integrators design lighter, smaller, and more efficient inverters, ST offers a complete portfolio including:
These components enable system developers to reduce thermal losses, improve power density, and support modular inverter designs for faster development and deployment.
Driving the Electrification Shift with Scalable, Sustainable Solutions
From intelligent battery management to high-performance motor control, STMicroelectronics delivers highly reliable, automotive-grade solutions and ecosystem support that help OEMs bring competitive, next-generation EVs to market faster and more efficiently. Whether it's two-wheelers, passenger EVs, or high-voltage eMobility platforms, ST offers a stable BOM, proven technology, and full lifecycle technical support—powering the path to smarter, safer, and more sustainable mobility.
