All battery is charged with the second charge controlling chip 11, and the electric current of the charging of battery is Ibatmax1+Ibatmax2.
For example, the first default maximum current Ibatmax1 of the output of the first charge controlling chip 10 is 3A, and second charges
Second default maximum current Ibatmax2 of the output of control chip 11 is 3A, then now the charging current of battery is maximum
Ibatmax is 6A.

If during threshold value, the first charge controlling chip 10 of control and the second charge controlling chip 11 enter constant voltage charging phase, and control the
One charge controlling chip 10 and the second charge controlling chip 11 are charged to the battery simultaneously with default constant voltage, with
And the voltage of the control output of adapter 13 is gradually lowered according to default rule, till being reduced to the second predeterminated voltage.

≤Ubat<During Uf, the first charge controlling chip 10 and the second charge controlling chip 11 all enter constant voltage charging phase, and first charges
Control chip 10 and the second charge controlling chip 11 output constant voltage Ureg, also, with charge carrying out, adapter 13 by
Decrescence little output voltage Ubus, improves so can the two charge controlling chip work efficiencies.
