Lithium-ion flow battery（ LFB） is a new type of energy storage battery. It is environmentally friendly,and has the comprehensive advantages of high power density,high energy density,independently designed output power and energy storage capacity,etc.,thus has a huge technological superiority in large-scale energy storage industry. In this paper,the system structure and characteristics of LFB were analyzed,and the hardware and software of the monitoring system were preliminarily investigated and designed,which includes the detection of both the battery module and the drive system. The intermittent driving mode of LFB was also investigated in the present work.It was found that the mechanical loss of the system can be decreased by reasonable setting of the driving time. This ensures the efficient and stable operation of lithium-ion battery.
