Abstract
A disposable lithium battery pack comprises a plurality of monomer cells connected in series and parallel; each monomer cell is connected in parallel with a diode D1; a cathode of the diode D1 is connected with an anode of the monomer cell; the monomer cell comprises an electric core and a cell cover; a containing space is arranged between the electric core and the cell cover; the diode D1 is arranged in the containing space. The diode D1 is integrated in each monomer cell, so the circuit structure of the battery pack is simplified, thereby solving complex PCB board circuit and series problems when the diodes D1 are integrated on the PCB board.
Description
Technical field
The utility model relates to lithium battery group, especially a kind of disposable lithium cell group.
Background technology
Lithium battery group is generally formed by some cell serial or parallel connections, for disposable lithium cell group, it generally has some cells to be in series, owing to being disposable battery, therefore each cell all be furnished with a diode, for preventing between cell charging mutually.In the circuit of existing disposable lithium cell group, diode is integrated on pcb board, and the cell quantity in battery pack is more, and the quantity of diode is also just also right, can increase the making sheet difficulty of pcb board, makes the circuit structure of pcb board become complicated.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of disposable lithium cell group, can make the circuit structure of battery pack become simple.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of disposable lithium cell group, described battery pack is formed by some cell series and parallel connections, each cell is in parallel with a diode D1, the negative electrode of diode D1 is connected with the positive pole of cell, described cell comprises battery core and battery cover, between described battery core and battery cover, is provided with accommodation space, and described diode D1 is located in described accommodation space.The utility model is integrated in diode D1 in each cell, enough makes the circuit structure of battery pack become simply, solves because diode D1 concentrates on pcb board the pcb board circuit complexity that causes, and a series of problem.
As improvement, described battery pack is connected with a diode D2, and the anode of diode D2 is connected with the positive pole of battery pack.Diode D2 is for preventing the direction charging of whole battery pack.
As improvement, the output of described battery pack is put IC with anti-mistake and is connected, and puts for preventing that battery pack from crossing.
The beneficial effect that the utility model compared with prior art brought is:
The utility model is integrated in diode in each cell, enough makes the circuit structure of battery pack become simply, solves because diode all concentrates on pcb board the pcb board circuit complexity that causes, and a series of problem.
Accompanying drawing explanation
Fig. 1 is battery circuit structural representation.
Fig. 2 is monomer battery structure schematic diagram.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of disposable lithium cell group, described battery pack is formed by some cell 1 series and parallel connections, and the present embodiment describes take four strings two and as example.Each cell 1 is in parallel with a diode D1, and the negative electrode of diode D1 is connected with the positive pole of cell 1.Described cell 1 comprises battery core 11 and battery cover 12, between described battery core 11 and battery cover 12, is provided with accommodation space 13, and described diode D1 is located in described accommodation space.
Described battery pack is connected with a diode D2, and the anode of diode D2 is connected with the positive pole of battery pack, and diode D2 is for preventing the direction charging of whole battery pack.
The output of described battery pack is put IC 2 with anti-mistake and is connected, and puts for preventing that battery pack from crossing.
The utility model is integrated in diode D1 in each cell 1, enough makes the circuit structure of battery pack become simply, solves because diode D1 concentrates on pcb board the pcb board circuit complexity that causes, and a series of problem.
