Problems solved by technology
Moreover, different users and different environments have different needs for batteries. Therefore, the current design of mobile terminals can no longer meet the market demand, nor can it meet the different needs of different users and different environments for batteries, and it is even more inconvenient for users to use.

The invention discloses a power source system applicable to batteries in a variety of specifications. The power source system comprises a control unit, a charging unit, a voltage boosting unit and a voltage reduction unit; the control unit is connected with a detection pin of the battery, obtains the rated voltage of the battery through the pin detection, and compares the rated voltage with set voltage; if the rated voltage is smaller than the set voltage, the control unit controls the charging unit to make the charging unit charge the battery; and if the rated voltage is larger than the set voltage, the control unit controls the voltage boosting unit to make the voltage boosting unit perform voltage boosting, and thereafter, charges the battery through the charging unit and controls the voltage reduction unit to make the voltage reduction unit perform voltage reduction on the battery so that the battery can supply power for a load. According to the power source system, the rated voltage of the battery is detected, corresponding actions are performed in the charging and discharging process of the battery, and therefore, the batteries in the variety of specifications can be supported to supply power for the load, and requirements of different users and different environments for the batteries can be satisfied, and thus, the power source system has high compatibility, and the selection and use of the batteries can be facilitated for the users. The invention also discloses an electronic device, a charging method and discharging method of a battery.
Description
technical field [0001] The invention relates to the technical field of charging, in particular to a power supply system, an electronic device, and a battery charging method and discharging method. Background technique [0002] With the development of electronic product technology, users have higher and higher requirements for accessories of electronic products. Such as the battery on the mobile terminal. In the design of mobile terminals, batteries of one specification are generally supported, but there are many batteries of different specifications with rated voltages such as 3-4.2v, 3-4.8v, 3-5.6V, etc. on the market, and different specifications The chemical composition and performance of different batteries are also different. There are lithium batteries, lithium-titanium batteries with better high temperature resistance, and iron batteries with better low temperature resistance. Moreover, different users and different environments have different needs for batteries. T...
