Lead-acid cell monomer consistency evaluation system and method

A lead-acid cell monomer consistency evaluation system and method. The invention belongs to the field of electric vehicles and new energy power generation and energy storage, specifically relates to a battery monomer consistency evaluation technology, and aims to solve the problem that consistency evaluation of a lead-acid cell monomer at present is not comprehensive enough. Output ends of a voltage sensor, an internal resistance sensor, a temperature sensor, charging performance of a current sensor, discharging performance of the current sensor, an electrical charge maintaining tester and a health state tester of lead-acid cell test equipment are connected with input ends of corresponding modules, the output end of each module is connected with the corresponding input end of a monomer consistency comprehensive evaluation module, and finally an evaluation is carried out through a monomer consistency comprehensive evaluation program. The lead-acid cell monomer consistency evaluation system and the method comprehensively consider consistency of the lead-acid monomer cell in seven aspects, ensure scientificity and accuracy of consistency of the lead-acid cell monomer, and are suitable for lead-acid monomer cell consistency evaluation.
