摘要：A method for evaluating a remaining electric charge of a battery that is utilizedfor supplying a single chip system includes: receiving signals from the battery and

outputting parameters corresponding to the received signals; temporarily storing theparameters; and calculating the remaining electric charge, and when the single chipsystem wakes up from a sleep mode, updating the remaining electric charge according tothe temporarily stored parameters. An associated single chip system includes: a powermanagement unit for receiving signals from a battery and outputting parameters

corresponding to the received signals; a storage unit, coupled to the power managementunit, for temporarily storing the parameters; and a control unit, coupled to the storageunit, for calculating a remaining electric charge, wherein when the single chip systemwakes up from a sleep mode, the control unit updates the remaining electric chargeaccording to the parameters from the storage unit.
