The embodiment of the invention provides a charge-discharge control method and a charge-discharge control system. The charge-discharge control method comprises steps that a mobile terminal transmits a preset data instruction to a charging device and the charging device transmits an acknowledgment signal to the mobile terminal according to the data instruction; if receiving the acknowledgment signal, the mobile terminal detects the remaining battery capacity value of each of at least two batteries, determines a charging current value based on the remaining battery capacity values, and controls the charging device to charge the at least two batteries with the charging current value, otherwise, controls a voltage conversion module to convert the voltage input by the charging device into a preset output voltage value and charges the at least two batteries with the output voltage value. Thus, when the charging device charges the mobile terminal, the batteries are selectively charged, thereby increasing the diversity and the compatibility of charging modes.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a charging and discharging control method and a charging and discharging control system. Background technique [0002] With the development of science and technology, the application of mobile terminals has become more and more extensive, and the charging technology related to mobile terminals has also attracted much attention. At present, for different charging devices, the charging method is mainly to use the charging device to output the charging voltage or charging current, and then realize the power supply to the system after being converted by the voltage conversion module. However, due to the difference in the compatibility of the charging device, the charging device The charging efficiency is low, the energy loss is large, and the heating phenomenon is serious. It can be seen that the current charging method is single, and the compatibility between the mobile term...
