See also Fig. 1, the portable terminal that the utility model embodiment provides is mobile phone, video camera, notebook or MID (Mobile Internet Devices, mobile internet device), it comprises, charging input end mouth 110, voltage sample module 120, switching tube 130, baseband chip 140 and rechargeable battery 150, described rechargeable battery 150 comprises battery pack BAT.
Wherein, the ADC port of described baseband chip 140 (analog-to-digital conversion port) is connected with the dividing point of described voltage sample module 120, the GATEDRIVE port of described baseband chip 140 is connected with the first input end of described switching tube 130, second input of described switching tube 130 is connected with charging input end mouth 110, the output of switching tube 130 is connected with the positive pole of described battery pack BAT, the negative pole of battery pack BAT connects power supply by described voltage sample module 120, and the minus earth of battery pack BAT.
Described rechargeable battery 150 is lithium battery or other rechargeable battery, and described charging input end mouth 110 is used to insert charger or USB (Universal Serial BUS, USB) data wire is given described rechargeable battery charging.
Described voltage sample module 120 is used for the charging voltage of rechargeable battery 150 is sampled, and the sampled voltage that obtains exported to baseband chip, switching tube 130 is used to control the size of portable terminal charging current, baseband chip 140 then is used for the size according to the sampled voltage of voltage sample module acquisition, to switching tube 130 output corresponding driving voltages, thereby control the degree of described switching tube 130 conductings, finally control the size of portable terminal charging current.
See also Fig. 2, described voltage sample module 120 is made of first resistance R 1 and 2 series connection of second resistance R.Wherein, described first resistance R 1 is encapsulated in the described rechargeable battery 150, so rechargeable battery 150 is an integral body that is made of the battery pack BAT and first resistance R 1.
