Structure based on above-mentioned mobile terminal hardware configuration, communication device proposes each embodiment of the method for the present invention.

As shown in figure 3, showing a kind of one embodiment of mobile terminal double-battery charge electric installation of the present invention.The shifting of the embodiment Moving terminal double-battery charge electric installation includes:

First Battery disposal module 10, for charging to the first battery, and obtain after mobile terminal enters charge mode The voltage and current of first battery；

In the present embodiment, there are two battery, the type of mobile terminal can be set according to actual needs for mobile terminal setting It sets, for example, mobile terminal may include the terminal that mobile phone, iPad etc. can be charged with double cell.

Quick charge requirement can either be carried out in order to meet mobile terminal can promote integral battery capacity again, the mobile terminal Quick charging battery and common batteries are used simultaneously, and the characteristics of quick charging battery is to be able to bear larger current and be full of in a short time Electricity, but battery capacity is smaller；The characteristics of common batteries, is that battery capacity is larger, but charging current is small and the charging time is longer.Its In, the first battery is quick charging battery, and the second battery is common batteries.It below will be using the first battery as quick charging battery and the second battery It is described in detail for common batteries.

Mobile terminal insertion charger enter charge mode after, the first Battery disposal module 10 first to quick charging battery into Row charging, when rechargeable battery is full of fastly, for example, being charged to 80% electricity, then respectively to quick charging battery and common batteries point Not Fen Pei charging current charge.Therefore, the first Battery disposal module 10 needs the voltage detection unit by quick charging battery The voltage of quick charging battery is detected, and the electric current of quick charging battery is detected by the current detecting unit of quick charging battery, so as to The charging situation of quick charging battery is known according to the voltage and current of quick charging battery.

Voltage and temperature acquisition module 20 are greater than preset voltage value, and described for the voltage when first battery The electric current of one battery is less than pre-set current value, then obtains the current voltage and temperature of first battery every preset time, with And obtain the second battery current voltage and temperature；

After the voltage and current of quick charging battery obtained above, voltage and temperature acquisition module 20 judge quick charging battery Whether voltage is greater than preset voltage value and whether the electric current of quick charging battery is less than pre-set current value, the preset voltage value and pre- If current value can according to the concrete condition of quick charging battery flexible setting.For example, presetting electricity for the quick charging battery of 4.35V Pressure value may be configured as 4.2V；Pre-set current value can be configured according to the capacity of quick charging battery, may be configured as battery total capacity 20%.

If the voltage for being unsatisfactory for quick charging battery is greater than preset voltage value and the electric current of quick charging battery is less than pre-set current value, Voltage and temperature acquisition module 20 continue to sentence the voltage and current for detecting obtained quick charging battery after waiting preset time It is disconnected.The preset time may be configured as 5 seconds, can also flexible setting as the case may be, do not limit the present invention.If quick charging battery Voltage when being greater than the electric current of preset voltage value and quick charging battery and being less than pre-set current value, show that the electricity of quick charging battery soon fills Man Liao, for example, quick charging battery has been charged to 80% electricity.At this point, in order to obtain the charging of quick charging battery and common batteries Electric current, to charge simultaneously to quick charging battery and common batteries simultaneously, voltage and temperature acquisition module 20 are by quick charging battery The voltage detection unit voltage current to quick charging battery detect, and by common batteries voltage detection unit to common The current voltage of battery is detected, and detects the current temperature of quick charging battery by a temperature sensor, and by another Temperature sensor detects the current temperature of common batteries.

Charging current determining module 30, for according to first battery current voltage and temperature, second battery Current voltage determines the charging current of first battery, according to second battery current voltage and temperature, described The current voltage of one battery determines the charging current of second battery；
