A Blockchain-Based Internet of Things (IoT) Network for Security-Enhanced Wireless Battery Management Systems

Wireless battery management systems (WBMSs) are recently proposed to solve critical wiring-harness issues in conventional BMSs. It is expected that the emerging Internet of Things (IoT) and cloud/edge computing technologies are expected to advance the WBMSs by fully utilizing IoT wireless network, powerful computing and unlimited cloud support, resulting in providing significant value in cost reduction, extended scalability, and greater visibility in the lithium-ion battery energy storage systems. However, the WBMSs present a growing threat from cyber-attacks as the WBMSs are always connected on networks and a lack of cybersecurity perspective is still prevalent in BMS usage and design phase. This paper explores blockchain technology for ensuring the communication and data security of an loT-enabled WBMS from malicious cyber-attacks. The concept of the proposed blockchain-based IoT network for WBMSs is validated by experimental studies.
