Abstract

The invention discloses a power circuit which comprises a power detection unit, a control unit and a switching unit, wherein the power detection unit is used for detecting whether a plurality of power supplies, including a green power supply, are provided to the power circuit or not and also detecting a power value provided by the green power supply; in addition, the control unit is electrically coupled to the power detection unit and a load so as to detect the electricity consumption power of the load and output a switching signal to the switching unit according to the electricity consumption power of the load and the detection result of the power detection unit. Therefore, the switching unit can select the green power supply and at least one other power supply to supply the electricity to the load if necessary according to the switching signal.

Description

technical field [0001] The present invention relates to a power management technology, and in particular to a power management technology including green power and commercial power. Background technique [0002] For various current portable electronic products, such as Personal Digital Assistant (PDA), Notebook Computer, electronic dictionary, digital camera, etc., batteries are an essential equipment. And because the rechargeable secondary battery (or rechargeable battery) has an economical and environmentally friendly power supply method, it is increasingly popular in the use of portable electronic products. Among them, lithium batteries are the most widely used rechargeable batteries. [0003] Generally, a battery charger must be used when charging a secondary battery, and the battery charger converts the indoor commercial power into a charging power source with a certain voltage level through a transformer, and uses the charging power source to charge the secondary batt...
