BATTERY SENSOR MEASURING AND SAVING THE STANDARD DEVIATION OF AN INTERNAL RESISTANCE OF AN INITIALLY APPLIED BATTERY, RE-MEASURING THE STANDARD DEVIATION OF THE INTERNAL RESISTANCE IN CASE THAT A BATTERY REPLACEMENT IS SUSPECTED, AND AN OPERATING METHOD THEREOF

摘要

PURPOSE: An operating method of a battery sensor is provided to produce information having a relatively high accuracy during a battery replacement.;CONSTITUTION: An operating method of a batter sensor comprises the following steps: A battery sensor(10) comprises a measuring part(120) and a storing part(110). The measuring part measures the internal resistance of a battery when the power source is initially supplied from the battery, and calculates the average. The measuring part calculates the standard deviation of the internal resistance, and determines the standard variation which is a standard for determining the battery replacement by the standard deviation of the internal resistance. The storing part stores the internal resistance, the average, the standard deviation, and the standard variation.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Storing part; (120) Measuring part; (AA) Battery
