发明名称 BATTERY REMAINING CAPACITY MEASURING DEVICE
摘要 PROBLEM TO BE SOLVED: To reduce the scale of a firmware of a micro-controller provided for prediction of a battery remaining capacity, and to reduce the load for the prediction of the remaining capacity by a main processor. SOLUTION: This battery remaining capacity measuring device integrates a charged current value and a consumed current value flowing in a battery 1 integrated in an electronic equipment having the main processor 9, and predicts the battery remaining capacity by the main processor 9 by utilizing the integration result. The micro-controller 6 including a first integration circuit 4 is provided in order to integrate the detected current value. The main processor 9 is equipped with a second integration circuit 7 in order to integrate furthermore the integration result integrated by the first integration circuit 4 of the micro-controller 6, and predicts the battery remaining capacity based on the result integrated by the second integration circuit 7.
