GB/T 9969 General principles for instructions for use of industrial products GB/T 29840 Terminology for all-vanadium redox flow batteries GB/T 33339-2025 Test methods for all-vanadium redox flow battery systems NB/T 42134 Technical Specifications for All-vanadium Redox Flow Battery Management Systems 3 Terms and Definitions The terms and definitions defined in GB/T 29840 and the following apply to this document. 3.1 Vanadium flow battery; VFB An energy storage device that converts electrical energy into chemical energy through the electrochemical reaction of vanadium ions of different valence states in the positive and negative electrode electrolytes. Note. All-vanadium redox flow battery mainly consists of power unit (stack or module), energy storage unit (electrolyte and storage tank), electrolyte transport unit (pipeline, valve, pump, heat exchanger, etc.), It consists of parts such as a battery management system, but does not include charging and discharging equipment. [Source. GB/T 29840-2013, 2.1] 3.2 The charging energy that a battery can achieve under specified test conditions and methods. Note. The unit of rated charging energy is watt-hour (Wh), kilowatt-hour (kWh) or megawatt-hour (MWh). 3.3 The discharge energy that a battery can achieve under specified test conditions and methods. Note. The unit of rated discharge energy is watt-hour (Wh), kilowatt-hour (kWh) or megawatt-hour (MWh). 3.4 The ratio of the discharged capacity to the charged capacity of the battery under specified test conditions and methods. Note. Rated energy efficiency is expressed in percentage (%). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32509-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 32509-2025_English as soon as possible, and keep you informed of the progress.
