Abstract
The invention relates to a charging and power supplying two-in-one mobile power supply and a power supply management method capable of allowing a charging mode and a power supply mode to be automatically switched. A common mobile power supply only provides a standard charging voltage and charges a mobile device through a USB interface; due to the problem of energy conversion efficiency of the mobile power supply, the ultimate utilization efficiency of the mobile power supply is only about 60%, and the other energy is converted into heat and is wasted. The mobile power supply can output charging voltages and power supplying voltages according to needs; when a power supply management chip at the mobile device end detects that input voltages are within the range of the charging voltages, a charging mode is started; when the power supply management chip detects that the input voltages are within the range of power supplying voltages, an external power supply mode is started. When the external power supply mode is used, the energy utilization efficiency of the mobile power supply can almost reach 100%, and use time of the device is prolonged much.
Description
Technical field
The present invention relates to portable power source and method for managing power supply.
Background technology
Existing common portable power source is all that output charging voltage is to charging of mobile devices.Boosting, in charging process, energy conversion efficiency is low, and final service efficiency only has 60% left and right, and remaining electric weight all changes into heat and wasted.
Summary of the invention
Generally, the charging voltage of the mobile devices such as mobile phone is 5V, and the supply power voltage of battery is 3.7V.And the mobile devices such as most of mobile phone all do not have external power source input interface.Portable power source of the present invention, can export two kinds of voltages, and one is charging voltage, can give charging of mobile devices.One is supply power voltage, can be used as external power source to mobile power supply equipment.Two kinds of voltages can, in same delivery outlet output, also can be exported by two delivery outlets.At mobile device end, when power management chip detects that the voltage of inputting from portable power source is in charge voltage range, enter charge mode.Detect that input voltage is in the time of power supply voltage range, breaking inner power supply, enters external power source pattern.Under external power source pattern, the service efficiency of power supply almost can reach 100%, and the portable power source of same capacity can use the longer time.
Claims (3)
1. portable power source and the method for managing power supply that charging is two-in-one, it is characterized in that selecting as required to export charging voltage or supply power voltage, the power management chip of mobile device end can enter charging or powering mode according to the voltage of input automatically.
2. portable power source according to claim 1, is characterized in that being chosen in two kinds of voltages of same delivery outlet output by button, also can be by two kinds of voltages of two delivery outlet output.
3. method for managing power supply according to claim 1, it is characterized in that at mobile device end, in the time that power management chip detects that the voltage of inputting from portable power source is in charge voltage range, enter charge mode, in the time detecting that input voltage is in power supply voltage range, enter external power source pattern.
