3 Terms and definitions
For the purposes of this document, the following terms and definitions, as well as those
given in GB/T 29840, apply.
3.1
vanadium flow battery; VFB
vanadium flow battery system
An energy storage device that achieves the interconversion of electrical energy and
chemical energy through the electrochemical reaction of vanadium ions in different
valence states in the positive and negative electrode electrolytes.
Note. A vanadium flow battery is mainly composed of power units (stacks or
modules), energy storage units (electrolyte and storage tanks), electrolyte
delivery units (pipelines, valves, pumps, heat exchangers, etc.), and battery
management systems, but does not include charging and discharging
equipment.
