1. A charging method for charging a battery of a mobile terminal via a power adapter, the method comprising:

  • obtaining current state parameters of the battery, wherein the current state parameters indicate the current temperature of the battery and the current state of charge of the battery;

    determining a mapping relationship from one or more of mapping relationships based on the current temperature of the battery, wherein the one or more of the mapping relationships correspond to the different temperatures of the battery, each of the one or more of the mapping relationships indicates a mapping relationship between the state of charge of the battery and a charging parameter of the battery under a preset temperature of the battery, the charging parameter comprises at least one of a charging voltage from the power adapter, a charging current from the power adapter, and a charging mode of the power adapter, and the charging mode comprises at least one of constant voltage charging stage, constant current charging stage, and pulse charging stage;

    determining the current charging parameter of the battery based on the determined mapping relationship and the current state of charge of the battery; and

    charging the battery of the mobile terminal according to the current charging parameter.
