Refer to Fig. 1, Fig. 1 is the flow chart of a kind of method for managing power supply disclosed by the invention.This method for managing power supply comprises:
The electrical parameter of storage battery or batteries in step S11:PDU detected electrons equipment.
When electronic equipment is in the first operational mode, the EC in electronic equipment enters low-power consumption mode thereupon and runs.Be in the process of the first operational mode at electronic equipment, by the electrical parameter of the storage battery in PDU detected electrons equipment or batteries.Electronic equipment power consumption is in the first operating mode less than power consumption in the second operating mode, in enforcement, the first operational mode of electronic equipment includes but not limited to stand-by/sleep mode, sleep pattern and ready mode (ConnectedStandby).
It should be noted that, the operation that PDU detects the electrical parameter of storage battery or batteries can perform according to predetermined period, such as: from the moment that electronic equipment enters the first operational mode, often performs one-time detection operation through 5 minutes.Certainly, PDU also irregularly can perform the operation of the electrical parameter detecting storage battery or batteries, such as: when electronic equipment just enters the first operational mode, sense cycle is set as larger numerical value, when the electricity of storage battery or batteries is lower, sense cycle is set as less numerical value.
Step S12:PDU judges whether the electrical parameter detected meets the charge condition preset.
When PDU detects the electrical parameter of storage battery or batteries, judge whether this electrical parameter meets the charge condition preset, this charge condition can for detecting the electrical parameter that obtain lower than corresponding threshold value, or the difference that current time detects between electrical parameter that the electrical parameter that obtains and electronic equipment entered for the first operational mode moment reaches respective threshold.

When PDU detect the electrical parameter obtained meet default charge condition time, need to charge to storage battery or batteries, now, PDU is to EC output order, and this instruction is used for waking up EC and carries out charging and control.
The instruction that step S14:EC response pdus exports, controls charging circuit and carries out charging operations.
When electronic equipment is in the first operational mode, EC enters low-power consumption mode.When EC is under low-power consumption mode, do not respond inner RTC.EC is after the instruction receiving PDU output, and respond this instruction and be waken up, namely EC reverts to normal operation mode from low-power consumption mode, controls charging circuit and charges to storage battery or batteries.
