Pond powers;Discharge and recharge detection unit detection mobile phone enters charged state, then cuts off battery powered, directly powered using AC, at the same time
Charge to battery;After exterior AC input removes, which automatically switches to battery powered.
Compared with prior art, the invention has the advantages that:
1) when using battery powered, battery temperature detection unit meeting sampling battery temperature, once battery temperature is higher than setting
Threshold value, charge-discharge control unit will be temporarily switched off battery powered and close system power consumption components, switch to interim energy-storage units
Power supply, when detecting that battery temperature is less than given threshold, reverts to battery powered.Effectively prevent mobile phone in use
Phenomena such as there is battery overheat and causing to occur on fire, explosion;
2) when mobile phone enters charge mode, charge mode detection unit detection mobile phone enters charged state, cuts off battery
Power supply, is directly powered, and charge to battery using AC;After exterior AC input removes, module control switches to battery confession
Electricity.Prevent mobile phone in charging using the battery of appearance while the situation of discharge and recharge, caused battery loss and battery are serious
Fever cause it is on fire, explosion phenomena such as.
