The present invention relates to a method and apparatus for measuring the residual capacity of a lithium primary battery. The method for measuring the residual capacity of a lithium primary battery according to the present invention comprises: a step of receiving the measured voltage value of the lithium primary battery for supplying power to a device and the current consumption of the lithium primary battery for a predetermined period, and comparing the measured voltage with a reference voltage; a step of increasing a counter if the measured voltage of the lithium primary battery is smaller than the reference voltage, and calculating the ratio of the current consumption to the current capacity of the lithium primary battery; a step of generating an alarm signal in accordance with the calculated ratio; and a step of transmitting the generated alarm signal to the outside. According to the present invention, the residual capacity of the lithium primary battery can be checked in a more accurate manner complexly using a voltage size and current capacity, and battery consumption status is indicated through an alarm such that the battery consumption status can be checked in advance. |
