eBM 5 and FPT Industrial’s battery management

Control logic, this is the genuine electrification challenge that FPT Industrial’s eBM5 system has taken up. In synergy with Potenza Technology, they have developed and marketed the eBM 5 battery management system (Bms) for high-voltage batteries in Turin, which has been awarded ISO 26262 ASIL C certification as a stand-alone system by TÜV SÜD. A FPT battery for marine applications can be found HERE.

This result highlights the qualities of the fifth-generation battery management system, designed and developed entirely in-house by the integrated FPT Industrial and Potenza Technology team, from the circuitry right through to the software base and application layers. This system by a modular design at its core, it is compatible with 400- or 800-volt battery systems, which can be configured at an application level to optimize vehicle efficiency and performance. This enables OEMs to maximize the system’s effectiveness for each use case, right across the mobility spectrum – from commercial vehicles through to hypercars – including multi-pack management (which is not in scope of the certification) without an additional controller. The eBM 5 is currently in volume production for the IVECO eDaily MY24, as well as for other applications.

Pierpaolo Biffali, Vice President Product Engineering at FPT Industrial, commented: “This is an important step forwards in consolidating our electrification roadmap to accelerate decarbonization of the commercial vehicles segment. Each technological innovation we make always translates into tangible value for our customers, and the eBM 5 represents a solid way to ensure the efficient and safe operation of their battery electric vehicles.”

Neeta Khare, Battery and Fuel Cell Director at FPT Industrial, commented: “Throughout the development phase, the team was driven by the principle of making our product robust, reliable, and safe. As a result, we implemented significant improvements across various areas, including processes, testing infrastructure, design documentation, and traceability – from requirements to testing. This enhanced approach has led to the TÜV SÜD ASIL C certification and has also further strengthened our confidence in the reliability and safety of our BMS product.”

Richard Devenport, General Manager & Head of Battery Development at Potenza Technology, an FPT Industrial brand, stated: “This is a true achievement that has been years in the making. The goal was always to produce an OEM standard Battery Management System suitable for a wide range of vehicles. While other BMS suppliers often use the ‘self-certification’ process, where their work products are reviewed within their own company to confirm compliance to the standard, we aimed to have ours assessed by an external body, to guarantee a level of quality and completeness that few others can boast. We backed up that claim by going the extra mile to obtain certification from TÜV SÜD, one of the world’s leading experts on functional safety and a founding participant in the establishment of the ISO 26262 standard.”

ISO 26262 and ASIL

ISO 26262 is an international standard for functional safety in the automotive industry, applied to electrical and electronic systems that consist of hardware and software components in vehicles. This standard defines the requirements for both the safety-relevant functions of the system and the development process, ensuring that an adequate level of safety is maintained throughout the vehicle lifecycle. The standard is based on ASIL (Automotive Safety Integrity Level), a risk classification system that analyzes potential hazards by considering the severity, frequency, and controllability of the vehicle’s operational scenarios.
