Device for measuring the quantity of electricity stored in a battery.

摘要

A device for measuring the quantity of electricity stored in a battery of a transceiver comprises a voltage detection circuit (2) for detecting the battery voltage, an A/D converter (3) for converting the detected battery voltage into data, and a calculation circuit (4) for calculating the quantity of battery electricity from the voltage data. The A/D converter operates to sample the battery voltage during the period when transmission and reception are off and thus when the battery voltage does not pulsate, whereby the battery electricity can be evaluated accurately. <IMAGE>
