Abstract
A method for evaluating a remaining electric charge of a battery that is utilized for supplying a single chip system includes: receiving signals from the battery and outputting parameters corresponding to the received signals; temporarily storing the parameters; and calculating the remaining electric charge, and when the single chip system wakes up from a sleep mode, updating the remaining electric charge according to the temporarily stored parameters. An associated single chip system includes: a power management unit for receiving signals from a battery and outputting parameters corresponding to the received signals; a storage unit, coupled to the power management unit, for temporarily storing the parameters; and a control unit, coupled to the storage unit, for calculating a remaining electric charge, wherein when the single chip system wakes up from a sleep mode, the control unit updates the remaining electric charge according to the parameters from the storage unit.
