Title:
CURRENT INTEGRATED AMOUNT MEASURING DEVICE, BATTERY REMAINING AMOUNT MEASURING DEVICE, ELECTRONIC APPARATUS, CURRENT INTEGRATED AMOUNT MEASURING METHOD AND INFORMATION COLLECTION SYSTEM
Document Type and Number:
Japanese Patent JP2018059778
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To precisely calculate current integrated amount.SOLUTION: The current integrated amount measuring device includes: a first element the resistance value of which changes depending on integrated amount of the current flowing thereon; a second element in which the degree of change of the resistance value depending on the integrated amount of the current flowing thereon is smaller than that of the first element; and an integrated amount calculation part that calculates the current integrated amount as an integrated amount of current which flows on a current channel inserted between the first element and the second element in series based on the resistance value of the first element and the resistance value of the second element.SELECTED DRAWING: Figure 1
