Abstract: 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.

Abstract: A method of diagnosing a battery and adaptively adjusting charging modes of the battery includes the steps of initially charging the battery using a constant current mode, wherein the battery is charged by a fix current in the constant current mode; monitoring a deterioration index by a battery management system (BMS), the deterioration index including a highest temperature (Tempmax), an instantaneous temperature difference (ΔTemp), an instantaneous voltage difference (ΔV), an instantaneous internal resistance (IRmax), and a state of charge (SoC) of the battery; when Temp exceeds a predetermined temperature threshold, pausing charging the battery; charging the battery by a constant power charging mode when Tempmax becomes smaller than 90% of the predetermined temperature threshold, wherein the battery is charged by a fix electric power in the constant power mode; charging the battery by the constant current charging mode when Tempmax becomes smaller than 50% of the predetermined temperature thresh old.
