Below in conjunction with Fig. 2 the charging method of the mobile communication terminal of prior art is described.
The control part 90 of above-mentioned mobile communication terminal (MS) is for the charging (CHARGING) of battery portion 20, detection by input current I1 judges whether to have connected adapter 70 (seeing step S10), above-mentioned judgement (seeing step S10) is the result detected input voltage I1 and be judged as when having connected adapter, detects the builtin voltage (seeing step S20) of battery portion 20.
Above-mentioned control part 90 is analyzed detected battery portion 20 builtin voltages of above-mentioned steps S20, judge whether the S30 that charges to battery portion 20, when above-mentioned determining step S30 result can not charge, turn back to the above-mentioned phase I (seeing step S10), when charging simulation (ANALOG) charging control signal is outputed to base stage (B) end of above-mentioned transistor seconds 40, set other electric current of level that is provided with is imported (seeing step S40) as input current I1.
The voltage that above-mentioned control part 90 check and analysis occur in second resistance, 30 two ends descends, judge to continue to import or along with the input current I1 that finishes of charging can not be with set current level input with the set current level that is provided with input current I1, therefore, can judge that having finished charging still continues charging (seeing step S50), above-mentioned judgement (seeing step S50) result does not finish charging and need proceed to charge the time, turn back to above-mentioned second stage (seeing step S20) and repeat charging, finished charging back complete charge step.
In the aforesaid prior art, above-mentioned adapter is 70 that provided, fixedly install according to control part 90, the size of input current I1 by the first transistor 60 inputs.
