Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the lithium battery kit of the utility model embodiment.
Fig. 2 is the electrical block diagram of the lithium battery protection circuit plate of the utility model embodiment.
Embodiment
The utility model proposes a kind of Portable movable printer lithium battery kit, be described in detail as follows in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1, wherein 1 is lithium battery to the overall structure schematic diagram of the lithium battery kit of the utility model embodiment, and 2 is lithium battery protection circuit plate, and 3 is battery box, and 4 is battery case upper cover.Lithium battery protection circuit plate is connected with lithium battery, and lithium battery is placed in battery box, is stamped battery case upper cover above.Lithium battery adopts single-unit lighium polymer battery core, has the advantages such as capacity is large, volume is little, safe.In lithium battery protection circuit plate 2, three small rectangle icon representation three five metals contact output interfaces arranged side by side.
As shown in Figure 2, described lithium battery protection circuit plate comprises two li-ion cell protection IC U1 and U2, two MOS switch U3 and U4, two electric capacity C1 and C2, temperature and resistance R5, five conventional resistance R1, R2, R3, R4 and R6, temperature and resistance output interface T, power supply positive pole output interface P+, power supply negative pole output interface P-to the electrical block diagram of lithium battery protection circuit plate.Wherein, U1 and U3 is connected in series, U2 and U4 is connected in series, U1 and U2 is connected in parallel.In addition, the terminal B+be connected with negative pole with the positive pole of lithium battery respectively with B-of lithium battery protection circuit plate.
The pin position of two li-ion cell protection IC U1 and U2 is described as follows:
The mark of pin number 1 is DO, is control of discharge FET gate pole splicing ear (CMOS output); The mark of pin number 2 is VM, is the voltage detection terminal (overcurrent detection terminal) between VM-VSS; The mark of pin number 3 is CO, is control of discharge FET gate pole splicing ear (CMOS output); The mark of pin number 4 is DP, is measuring delay time for use in said calibrating terminal; The mark of pin number 5 is VDD, is positive supply input terminal; The mark of pin number 6 is VSS, is negative supply input terminal.
Concrete mode of operation is such: the voltage detection terminal VM mouth of li-ion cell protection IC U1 and U2 is for detecting cell voltage, when detecting that cell voltage is greater than 4.28V, show that now battery electric quantity is full of, then charging controls to close U3 or U4 MOS switch with FET gate pole splicing ear CO mouth, thus input is ended, prevent battery from occurring overcharge conditions; Similarly, when detecting that battery is in low electricity (voltage is less than 3.0V), then control of discharge FET gate pole splicing ear DO mouth closes U3 or U4 MOS switch, thus output is ended, and prevents battery from occurring to one's heart's content condition.Two MOS switches U3, U4 form two protection switch circuit together with resistance R6; one of them li-ion cell protection of U1 or U2 IC is only needed normally to work; can normal control MOS switch U3, U4, then the super-charge super-discharge defencive function of whole battery pack just can be protected.Two protect IC concurrent working, the single normal power supply and super-charge super-discharge defencive function that do not affect integral battery door box of breaking down.Contrast traditional single protect IC scheme, improve reliability, reduce failure rate.
Because lithium battery protection circuit plate is also loaded with temperature and resistance R5, connect with temperature and resistance output interface T-phase, T outputs signal to printer, can facilitate the temperature of the real-time monitoring battery group of printer, prevents the too high initiation potential of battery pack temperature and fault.
P+, T and P-tri-output interfaces adopt five metals contact, can mount and dismount easily.
Preferably, li-ion cell protection IC adopts the special single series lithium battery protection IC of NSK, and model is S-8216.
A kind of Portable movable printer of the utility model lithium battery kit, adopts the jumbo lighium polymer battery core of high density, is better than traditional nickel-hydrogen chargeable cell; Output port adopts five metals contact to export, and is easy for installation and removal; The design of lithium battery protection circuit plate adopts two protect IC of original creation, and two chips parallel workings, have ensured battery operated reliability, have reduced failure rate.
