SUSTAINABILITY
improving the lifetime value of the battery, and the EV’s operational performance. Building on our proven, industry-leading, high accuracy cell monitoring sensing capabilities, ADI’s solution delivers real- time battery data insights, utilising secure intelligence at the edge, embedded software and wireless communication links, which are critical to the development of new systems and services for the entire battery life cycle. The capabilities present
insights to the BMS engine control unit (ECU). ADI provides a production-grade software block from where the insights can be accessed, and the platform can be

transfer the insights to the BMS ECU. Each RF MCU includes a comprehensive security subsystem compliant with ISO 21434 CAL-4. A key feature is the unique secure identity of each IC, which can be leveraged to build an insights history for each battery. Central processing (BMS ECU)—ADI algorithms fuse the processed data from multiple edge nodes to create battery pack and vehicle-level insights.
System value across the entire battery life cycle
OEMs are moving quickly to electrify their opportunities to empower sustained value delivery.
Automated EV manufacturing ADI Recharge eliminates the need for wiring harnesses. This enhances OEM’s robotic manufacturing capabilities so they are able to improve production assembly and manufacturing costs. The system is supportive of all known battery chemistries, including low cost chemistries and the increased modularity it provides scale EV production—from entry level to premium. As the wireless architecture is so robust, the software and network upgrades enable a reduction in battery material requirements. Compared to a wired network, the wireless network can be implemented quickly and easily and this greatly decreases development cycle time. There are also architectural-level savings enabled by ADI’s seventh-generation cell monitoring sensor—the ability to sense up to 24 channels using a single IC reduces coupling requirements, and the superior EMC performance eliminates the need for
structure, and for the manufacturers and suppliers to secure better variable costs with reduced overheads, while achieving faster time-to-market and production line helping create opportunities for a more reliable convergence of electric mobility with the clean energy grid.
So, what does the ADI battery insight platform look like end to end?
Starting at the source of data—Intelligent sensors right at the battery cells gather data wirelessly into a central management platform, which presents the processed
power than its predecessor, and some of that saved energy can be used to process valuable insights at the edge. Finally, just one IC can sense up to 100V stack or 24 series cells making it a highly integrated and Secure radio frequency microcontroller unit (RF MCU)—The IC’s embedded software controls the sensor operation and processes the data to feed ADI’s insights algorithms. These algorithms generate insights that can be used for applications such as fast charging and increased range, by estimating the state of charge (SoC) more accurately. The RF MCU’s ultra-robust radio and embedded network software
Digital twins for battery packs The age of the software vehicle is here. ADI’s system enables highly accurate digital twin services for battery packs. This targets ultra-robust RF performance, long before prototypes are available. This aids with improved battery pack design and planning, allowing for a much higher return on investment when in the development stages.
Improved vehicle reliability Going wireless enables removing the wire harness, which not only saves cost but also removes potential sources of failure in the vehicle. Wires and connectors can weaken or fail over time. Furthermore, the platform can
