Wireless Battery Management Systems (wBMS)
Analog Devices, Inc. wireless battery management system (wBMS) is a purpose-built solution, tailored for high reliability and the low latency requirements of automotive battery management systems. The wBMS network provides robust connectivity for the supervision of battery cells and control of the balancing current in electric vehicles or other large energy storage systems.
The wireless battery management system (wBMS) consists of ADI developed software that resides on a specifically developed system-on-chip. This low power integrated system-on-chip includes a 2.4 GHz ISM band radio and an embedded microcontroller (MCU) subsystem. These devices provide wireless communications between the battery cell monitoring chip and the battery management system controller (BMS controller).

ISO/SAE 21434产品认证
ADI的汽车无线电池管理系统(wBMS) Sentinel wBMS已获得ISO/SAE 21434产品认证，这是一款专为汽车电池管理系统量身定制的安全系统解决方案。ISO/SAE 21434是经过评估的汽车网络安全证书，这是对ADI在安全设计方面出色表现的认可，通过对电池生命周期的系统威胁评估和风险分析，将其纳入Sentinel wBMS中。评估结果证实，ADI在产品开发过程中采取了适当的保障措施，以满足CAL 4的要求。
NIST加密算法验证项目(CAVP)
ADI公司对ADRF88xx/89xx SoC中使用的所有加密算法实现进行认证以符合NIST CAVP计划。这些IC构成了Sentinel wBMS的基础。对使用的所有硬件和混合（硬件+固件）算法进行测试。
ISO 26262概念审查
ADI公司已完成由TÜV SÜD Rail GmbH实施的Sentinel无线电池管理系统(wBMS)通信层的概念审查。基于其概念报告（如果需要可提供）可以得出结论，在特定约束条件下，根据ISO 26262:2018的要求，Sentinel wBMS的安全通信层概念可用于支持高达ASIL D标准的安全通信。若需要wBMS Sentinel系统安全集成指南可以提供。
