Method and device for measuring hydrogen evolution of lead-acid storage battery

The invention relates to a method and a device for measuring hydrogen evolution of a lead-acid storage battery, and belongs to the technical field of lead-acid storage batteries. Comprising the steps of gas collection, correction gas quantity calculation, monomer power storage separated gas quantity calculation, hydrogen content measurement and power storage separated hydrogen quantity calculation. Gas separated out by electricity storage is collected through gas collection, the amount of corrected gas in a standard state is calculated through correction gas amount calculation, and the amount of gas separated out of the outside per ampere hour of each single storage battery in a charging state is calculated through calculation of the amount of gas separated out by electricity storage of the single storage battery; the volume percentage content of hydrogen in the collected gas is measured by measuring the hydrogen content, and the amount of hydrogen separated out of the storage battery per ampere hour is calcu
