A battery health state evaluation method for evaluating a health state of a battery comprises a charging step, an idling step, a pulse discharging step, an evaluation index calculating step, and an evaluation result yielding step. The evaluation index calculating step retrieves a continuous voltage data and a continuous current data in a charging process, an idling process, and a pulse discharge process and calculates a plurality of evaluation indexed according to the continuous voltage data and continuous current data. The evaluation indexes are associated with the health state of the battery. The evaluation result yielding step evaluates the health state of the battery according to the indexes and yields an evaluation result. Therefore, the battery health state evaluation method is easy, convenient, and effective in performing a test quickly and accurately.
