[Abstract]:As a new type of green energy, lithium battery has been used more and more widely, and has gradually replaced lead-acid battery as the power source of electric vehicles. Lithium batteries have four advantages over lead-acid batteries: (1) Lithium batteries do not contain harmful heavy metals such as cadmium, lead, and mercury; (2) Lithium batteries are light and nimble, weighing only about 1 / 4 of the weight of lead-acid batteries: (3) long life. The service life of lithium battery is about twice as long as that of lead-acid battery; (4) Lithium battery can be used normally in low temperature environment, and there is no problem that lead-acid battery can attenuate greatly at low temperature. However, with the extensive use of lithium batteries, the problems of lithium battery management, such as safety protection, fault analysis and diagnosis, anti-theft and life-cycle management, are becoming more and more prominent. In this paper, the lithium battery management system, hereinafter referred to as RFBMS system, is designed and implemented. On the basis of real-time monitoring and security protection of lithium battery status, the system adopts RFID technology to transmit battery information to lithium battery management platform to realize remote monitoring and management of lithium battery. The network layer and the application layer are composed of three parts. The sensing layer completes the functions of lithium battery protection and data acquisition, including the hardware and software design of lithium battery RFID protection board and RFID reader. The network layer completes the data transmission of lithium battery through Internet. The application layer completes the lithium battery remote monitoring and management function. RFBMS system is a school-enterprise cooperation project between Suzhou University and Jeopin Electric vehicle Co., Ltd., the system has been operated in Jeopi Electric vehicle Co., Ltd. The problems such as safety protection, fault analysis and diagnosis, anti-theft and life cycle management of lithium battery are solved.
