Beschreibung
Zusammenfassung:	The invention relates to an all-vanadium redox flow electric pile internal and external leakage detection method which comprises the following steps: step 1, simultaneously introducing detection gas with preset pressure into a positive electrode cavity and a negative electrode cavity of an electric pile, detecting the pressure of the two cavities, if the pressure of the two cavities is kept stable, determining that the electric pile has no leakage, and if the pressure of at least one cavity is unstable, determining that the electric pile has leakage; and 2, when the electric pile has no external leakage, introducing detection gas with preset pressure into the positive electrode cavity or the negative electrode cavity of the electric pile, detecting the pressure of the cavity into which the detection gas is introduced and the pressure of the cavity into which the detection gas is not introduced, if the pressures of the two cavities are kept stable, determining that the electric pile has no internal leakage, an
