A kind of lithium battery charger of many effects comprises charger; Input at said charger is provided with electronic switch, is provided with current detecting unit at the output of said charger; Also comprise comparator and toggle switch, the input of said comparator is connected with toggle switch with current detecting unit respectively, and the output of said comparator is connected with said electronic switch.
Further, said toggle switch is two grades of toggle switches.
Further, said toggle switch inside is provided with built-in power.
A kind of lithium battery charger charging method of many effects comprises the steps:
1) charging modes is set;
2) according to the charging modes that is provided with battery is charged;
3) detect charging current and compare with preset value;
4) according to comparative result whether charger is proceeded charging and make judgement.
Further, said step 1 comprises following two kinds of charging modes: a kind of for partly filling charging modes, a kind of in addition for completely filling charging modes.
Further, the preset value in the said step 3 has two, and one is the preset value that partly fills under the charging modes, and a kind of in addition is the preset value that completely fills under the charging modes.
Further, saidly partly fill preset value under the charging modes greater than the said preset value that completely fills under the charging modes.
Further, a kind of lithium battery charger charging method of many effects comprises the steps:
1) charging modes is set for partly filling charging modes;
2) battery is charged, and with charging voltage and the preset value that partly fills under the charging modes compare;
3) according to comparative result whether charger is proceeded charging and make judgement.
Further, a kind of lithium battery charger charging method of many effects comprises the steps:
1) charging modes is set for completely filling charging modes;
2) battery is charged, and with charging current and the preset value that completely fills under the charging modes compare;
3) according to comparative result whether charger is proceeded charging and make judgement.
Advantage that the present invention has and good effect: one, can realize partly filling and completely charging demand of lithium battery automatically, promptly when needs partly filled lithium battery, charger can partly charge the back auto power off; When needs completely filled lithium battery, charger can completely charge the back auto power off; Two, greatly reduced waste of electric energy; Three, well protected the life-span of lithium battery.

Embodiment
For further understanding technology contents of the present invention, characteristics and effect, enumerate following instance now, and conjunction with figs. specifies as follows:
As shown in Figure 1, the technical scheme that this specific embodiment adopts is: a kind of lithium battery charger of many effects comprises charger 2, comparator 4 and toggle switch 5; Input at said charger 2 is provided with electronic switch 1, is provided with current detecting unit 3 at the output of said charger 2; The input of said comparator 4 is connected with toggle switch 5 with current detecting unit 3 respectively, and the output of said comparator 4 is connected with said electronic switch 1; Said toggle switch 5 is two grades of toggle switches; Said toggle switch 5 inside are provided with built-in power.
A kind of lithium battery charger charging method of many effects comprises the steps:
1) charging modes is set, this specific embodiment has and partly fills charging modes and completely fill two kinds of charging modes of charging modes;
2) according to the charging modes that is provided with battery is charged;
3) detect charging current and compare with preset value, this specific embodiment has the preset value that partly fills under the charging modes and completely fills the preset value under the charging modes, saidly partly fills preset value under the charging modes greater than the said preset value that completely fills under the charging modes;
4) according to comparative result whether charger is proceeded charging and make judgement.
Further, a kind of lithium battery charger charging method of many effects comprises the steps:
1) charging modes is set for partly filling charging modes;
2) battery is charged, and with charging voltage and the preset value that partly fills under the charging modes compare;
3) according to comparative result whether charger is proceeded charging and make judgement.
Further, a kind of lithium battery charger charging method of many effects comprises the steps:
1) charging modes is set for completely filling charging modes;
2) battery is charged, and with charging current and the preset value that completely fills under the charging modes compare;
