With the rapid development of science and technology, lithium-ion batteries have become an indispensable part of our daily lives. From electric bicycles to electric vehicles, from portable electronic devices to large energy storage systems, the widespread use of lithium-ion batteries has brought great convenience to our lives. However, with the surge in the number of lithium-ion batteries, their potential safety risks have become increasingly prominent. Accidents such as fires and explosions occur from time to time, which not only pose a serious threat to people's lives and property safety, but also pose a huge challenge to environmental protection and social stability. In June this year, a fire in a lithium battery factory warehouse in South Korea claimed the lives of 22 people. Recently, a battery in an electric bicycle rental shop in downtown Manhattan caused a fire.
Traditionally, the temperature monitoring of lithium-ion batteries mainly relies on manual inspections and infrared temperature measurement equipment. Manual inspections are not only time-consuming and labor-intensive, but also easily affected by human factors, resulting in inaccurate temperature measurement results. Although infrared temperature measurement equipment can monitor temperature in real time, it is expensive and requires professional operation, which is costly and inefficient for large-scale battery storage and management. In addition, traditional temperature measurement methods can often only intervene after the problem occurs, and cannot provide early warning and prevention of potential safety risks. In this context, Brady Corporation has launched an innovative RFID-based temperature measurement solution, providing new protection for the safe use of lithium-ion batteries.
Advantages of RFID temperature measurement solution
In view of the limitations of traditional temperature measurement methods, Brady Corporation has launched an innovative RFID-based temperature measurement solution. The solution consists of passive UHF RFID sensor tags in the battery, reader antennas in the warehouse and software to identify temperature changes. It has the significant advantages of low cost, high efficiency and high reliability:
Low-cost, high-efficiency automated monitoring
Brady's RFID temperature measurement solution uses passive UHF RFID sensor tags that can be embedded inside or attached to the outside of the battery to quickly detect temperature changes. These tags are low-cost and easy to install, and can be used on a large scale in battery storage and management. At the same time, the solution is also equipped with fixed UHF RFID readers and 16-port multiplexers to limit the number of readers required at the site, further reducing hardware costs. Each reader can manage a storage area of approximately 12 meters by 4 meters high. Depending on the size of the battery, each antenna can interrogate two to three batteries, realizing real-time monitoring and efficient management of battery temperature.

High-precision temperature monitoring and early warning
Brady's RFID temperature measurement solution can not only monitor the temperature of the battery in real time, but also store and analyze temperature data through software. The software can store the latest temperature readings as well as the tag ID and approximate location, and can configure acceptable temperature thresholds according to user needs. When the temperature reaches or exceeds the threshold, the software triggers an alarm to send a warning message to the system user, indicating the tag that detected the temperature rise and its location in the warehouse. This high-precision temperature monitoring and early warning mechanism enables managers to promptly detect and deal with potential safety risks, effectively avoiding accidents such as fires and explosions.
Easy to deploy and expand application scenarios
Brady's RFID temperature measurement solution is easy to deploy and expand. The solution can be applied to battery storage and management scenarios of various sizes, from large warehouses to small production lines, and can easily achieve temperature monitoring and early warning. In addition, the solution can also be integrated with other management systems, such as warehouse management systems, production management systems, etc., to achieve data sharing and collaborative processing. This not only improves management efficiency, but also reduces management costs.
Remarkable results won multiple customer orders
In practical applications, Brady's solution has shown remarkable results. So far, seven companies are testing or deploying the system, and some are already able to identify rising temperatures before fires break out. In an initial pilot of the technology, three customers have successfully transitioned to full installations, including one end user operating a fully automated warehouse. The user used a combination of fixed readers and handheld readers to achieve real-time monitoring of approximately 100,000 batteries in the warehouse. With this technology, they are able to detect problems before they disrupt operations, allowing them to take quick action and reduce labor and operating costs.
In addition, RFID temperature measurement solutions can also be applied to scenarios such as electric vehicle charging stations and electric bicycle rental stores. In these scenarios, there are many batteries and many types, making management difficult. By adopting RFID temperature measurement solutions, real-time monitoring and early warning of battery temperature can be achieved, improving safety and management efficiency.
With the continuous expansion of lithium-ion battery applications and the continuous advancement of technology, RFID temperature measurement solutions will play a more important role in the future. On the one hand, with the continuous development of technologies such as the Internet of Things and big data, RFID temperature measurement solutions will be deeply integrated with these technologies to achieve more intelligent and automated temperature monitoring and management. On the other hand, with the continuous improvement of environmental awareness and the continuous improvement of regulations and policies, the safety and traceability requirements for lithium-ion batteries will become increasingly higher. RFID temperature measurement solutions will play an important role in this regard and provide strong support for the safe use and recycling of lithium-ion batteries.
The RFID-based temperature measurement solution launched by Brady Corporation provides new guarantees for the safe use of lithium-ion batteries. This solution has the significant advantages of low cost, high efficiency, and high reliability. It can realize real-time monitoring and early warning of battery temperature, and effectively avoid accidents such as fires and explosions. In the future, with the continuous advancement of technology and the continuous expansion of application scenarios, RFID temperature measurement solutions will play a more important role in the field of lithium-ion battery management and safety.
