Title: METHOD AND APPARATUS FOR DETECTING BATTERY TEMPERATURE AND ID
Abstract:
Provided are a method and apparatus for detecting a battery temperature and ID, said apparatus comprising, inside a battery, one end of an NTC resistor and capacitor Cid being connected in series to an NTC/ID pin; the other end of the NTC resistor and capacitor Cid being connected to a GND; the apparatus also comprises a resistor R1, one end of which is connected to an NTC/ID pin extending out from the battery; the other end of the resistor R1 is connected to the IO port of a host controller; the NTC/ID pin extending out from the battery is also connected to the ADC pin of the host controller. The present apparatus has simple circuitry and is low in cost; it occupies only one pin of the battery and one ADC of the host, and effectively improves accuracy in ID detection.
