<p>A mobile terminal, a charging method and a charging system for charging the mobile terminal in different temperatures. When the mobile terminal detects that a battery is being charged, by detecting in real-time voltage values of a charging circuit of the mobile terminal and of a battery temperature monitoring input connected to a thermistor of the battery, a prestored relationship table of voltage values of the battery temperature monitoring input and battery temperatures is queried, and a current battery temperature is acquired. A prestored relationship table of battery temperatures, charging voltages, and charging currents is queried on the basis of the current battery temperature, a charging voltage and a charging current that correspond to the current battery temperature are retrieved from the relationship table of the battery temperatures, charging voltages, and charging currents and are configured correspondingly as the current charging voltage and charging current. Until the battery is fully charged, the charging voltage and the charging current for charging the battery are adjusted on the basis of different battery temperatures, thus the battery is protected and the service life of the battery is extended. This is implemented via software. The method is simple and of reduced costs.</p> |
