Research on The State Evaluation of Lead-acid Batteries Based on Fuzzy Comprehensive Evaluation Method

The state evaluation of lead-acid batteries is a relatively systematic and difficult to quantify work. This article uses Analytic Hierarchy Process (AHP) and fuzzy mathematics related theoretical knowledge, combined with practical situations, to construct a battery state evaluation element system. The expert survey scoring method is used to determine the membership degree of each evaluation element, determine the evaluation model, and verify and analyze through experiments, This evaluation method can comprehensively, objectively, and accurately evaluate the status of batteries.
