“…Emerged BMSs have improved recently, but they still rely on complicated algorithms, and new hardware units, like implanted sensors, need to be developed in order to learn about the battery's internal state. The efficiency of management will be further improved by having access to the operating batteries' internal data, which will substantially increase the accuracy of status estimation [84].…”

Rechargeable batteries have recently experienced increases in productivity and the economy, solidifying their dominance in energy-intensive cultures. Regular performance monitoring is required to lessen the adverse environmental effects of batteries in the face of increased demand. The distinctive features of lithium-ion batteries (LIBs) make them an ideal choice for energy storage. Battery management systems (BMSs) are needed to make sure that LIB systems are safe and operate effectively. Critical problems in the existing structure and operation of BMSs are their limited data storage capacity and weak computational power. This paper studies the idea and architecture of cloud-based smart BMSs and offers some viewpoints on their performance, usability, and advantages for upcoming battery applications. While some of the benefits of sensors have been recognized for more than a hundred years, the combination of diverse sensing technologies with novel battery platforms has the potential to revolutionize the sector by changing how both new and old lithium-ion devices are used. This paper also highlights current advances and their associated benefits focusing on electrochemical, mechanical, acoustic, and optical sensors that can potentially boost battery sustainability and longevity.

The continuous increased energy density of lithium-ion batteries has led to growing concern about the safety issues, which has prompted the development of sensing technologies to achieve real-time state monitoring. However, the limited space in the lithium-ion battery pack presents great challenges of physical size and energy consumption for the existing current sensors. In the present work, a PVDF-TrFE/Metglass magnetoelectric laminate sensor with a minimized flexible structure and high temperature resistance was fabricated. By the in situ coating and polarization of the piezoelectric PVDF-TrFE on the magnetostrictive Metglass, the transition layer between them was eliminated to reduce the interfacial stress transfer losses. The well-formed interface resulted in high linearity over 0.981 and an excellent magnetoelectric response with a current sensitivity of 0.058 μV/mA. Additionally, the high Curie temperature of PVDF-TrFE provides the magnetoelectric sensor with high heat resistance over 120 °C. The PVDF-TrFE/Metglass magnetoelectric sensor can monitor the fluctuation of the lithium-ion battery current, enabling real-time detection and early warning of external short circuits and vibration impacts, presenting great value in lithium-ion battery safety monitoring.
