Brief description of the drawings
Fig. 1 is electrical block diagram of the present utility model.
In figure, A and B are that DC power access end, C are that pressurizer, D are that charging management chip, E are that charging main circuit, F are that constant-current source, NTC are that temperature sensor, T1 and T2 are that the resistance, the Z that adjust the charging interval is that resistance, the CMOS that adjusts charging capacity is that power switch, G are that stand-by power supply battery, H are load.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Fast and safely charging circuit of a kind of stand-by power supply battery, as shown in Figure 1, comprise DC power supply, stand-by power supply battery G, load H, power switch CMOS, the resistance Z of pressurizer C, charging management chip D, charging main circuit E, constant-current source F, temperature sensor NTC and the resistance T1 in adjustment charging interval and T2 and adjustment charging capacity; DC power supply is connected with pressurizer C with B incoming end by A, by providing working power to charging management chip after pressurizer C voltage stabilizing, the charging main circuit E of DC power supply connection simultaneously and constant-current source F power to them, and the output of charging main circuit E connects described stand-by power supply battery G and power switch CMOS and load H; Between pressurizer C and charging management chip D, connect the resistance T1 and the T2 that adjust the charging interval, between pressurizer C and stand-by power supply battery G, connect temperature sensor NTC, the resistance Z that adjusts charged electrical capacity is in parallel with stand-by power supply battery G.
The utility model is electric current quick charge greatly, and maximum can reach 5A, and charging main circuit E controls with high-power power switch CMOS, and electric current also can reach 5A; In this circuit, add constant-current source F can control power supply makes electric current remain constant current when to stand-by power supply battery G quick charge; In the time that stand-by power supply battery G is charged to 90%, charging management chip D sends instruction and transfers to and supply charging, supplies charging make circuit proceed to trickle charge with 1/18 pair of battery of fast charging current; In the time that stand-by power supply battery G temperature reaches preset value, temperature sensor NTC two ends provide control voltage, make charging management chip D send instruction, reduce charging current, prevent the infringement to stand-by power supply battery G; In the time that the charging interval reaches T1/T2, charging current transfers trickle-charge current to, to prevent from overcharging the generation of phenomenon; This circuit is hard-core to the capacity of battery pack, can change charging capacity as long as the resistance Z of charging capacity is adjusted in conversion.
