Abstract

The invention provides a smart double-battery system. The smart double-battery system comprises a charging unit, a power source management unit, a main battery, an auxiliary battery, a double-battery management unit, an application processor, a first precision resistor and a second precision resistor. The charging unit is connected with the power source management unit and is also connected with the double-battery management unit through the first precision resistor. The power source management unit comprises a lithium battery. One end of the main battery is connected with the double-battery management unit and the application processor. One end of the auxiliary battery is connected with the double-battery management unit and the application processor. The other end of the main battery is connected with one end of the auxiliary battery and then is connected with the ground terminal of the power source management unit through the second precision resistor. The application processor is connected with the double-battery management unit and the power source management unit. The invention further relates to a switching over and charging method of the double batteries. The smart double-battery system and the switching over and charging method of the double batteries have the advantages that the batteries are switched over accurately and the utilization rate of the batteries is improved.

Description

technical field [0001] The invention relates to the field of power supply, in particular to an intelligent dual battery system and a method for switching and charging the dual batteries. Background technique [0002] A common problem with Android phones is that they consume too much power, and users often have to carry power banks when they go out. However, the charging conversion efficiency of power banks is generally not high, and part of the energy is wasted in the form of heat. In the past, some dual-battery solutions were completely operated in the background, and users could not see the usage of the dual-battery on the interface. The traditional dual-battery solution uses voltage as the basis for battery switching. When the mobile phone is turned on, the battery voltage detected by the ADC is a closed-circuit voltage. Due to the internal resistance of the battery and the impedance of the PCB line, and the high power consumption of the Android phone, the voltage measu...
