Measuring apparatus and method for measuring remaining coulombs of electrical energy storage device and electronic device
A measuring apparatus includes a storing module, a measuring module, and a processing module. The storing module is used for storing maximum coulombs of the rechargeable electrical energy storage device, and a relation of various standard voltage and percentages of the remaining coulombs to the maximum coulombs. The measuring module is used for measuring an initial voltage of the rechargeable electrical energy storage device, and retrieving initial charged coulombs from the storing module. The processing module is used for calculating charged coulombs and discharged coulombs, and calculating the remaining coulombs of the rechargeable electrical energy storage device based on the charged coulombs or the discharged coulombs and the initial charged coulombs and updating the storing module with the remaining coulombs. A measuring method and an electronic device including a measuring apparatus for measuring the remaining coulombs are also disclosed.
