SYSTEM AND METHOD FOR DETERMINING A STATE OF HEALTH OF A POWER SOURCE OF A PORTABLE DEVICE

摘要

A method for determining a State of Health (SoH) of a power source of a portable device involves extracting a start voltage value of an examined power source; activating one or more hardware components of the portable device by a software, to increase the current consumption of the device, identifying a voltage drop rate of the examined power source and comparing a calculated voltage drop rate to pre-calculated threshold values stored on a database of a main server. A system for executing the method is also disclosed.

1. A method for determining a State of Health (SoH) of a power source of a portable device, the method comprising:
extracting at least one device parameter from said portable device; obtaining a start voltage value of said power source and a time stamp indicative of the time said start voltage value is obtained; activating hardware components of said portable device to increase current consumption of said device; identifying at least a first voltage drop relative to said start voltage value; calculating, based on pairs of consecutive voltage readings a voltage change value; comparing said calculated voltage change value of said power source to threshold values stored in a database; and determining said State of Health of said power source based on said comparison of said calculated voltage change value and said threshold values.
