Title:
APPARATUS AND METHOD FOR DETECTING STATE OF HEALTH OF BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/152823
Kind Code:
A1
Abstract:
A method for detecting the state of health of a battery. The method comprises: for a battery that does not supply power to a load for a period of time, determining a detected unit, collecting an open-circuit voltage and temperature of the detected unit, calculating to obtain a state-of-charge value and loss capacity of the battery of the detected unit, and then calculating to obtain a state-of-health value of the battery of the detected unit according to a ratio of the loss capacity of the detected unit to original capacity. An apparatus for detecting the state of health of a battery can accurately monitor a degree of attenuation of battery performance, and avoid impact on service.
