Document Type and Number:
WIPO Patent Application WO/2018/126901
Kind Code:
A1
Abstract:
A method and device for testing the health status of a battery. The method for testing the health status of a battery comprises: according to a set sampling period, continuously measuring voltage values and capacity values at the same moments of a battery to be tested (S101); calculating the capacity difference and voltage difference respectively according to the voltage values and capacity values measured twice (S102); determining the ratio of the capacity difference to the voltage difference (S103); and obtaining an aging coefficient corresponding to the determined ratio according to preset correspondences between ratios and aging coefficients (S104).
