Background technology
Lithium ion battery has substituted nickel-cadmium cell, Ni-MH battery, lead-acid battery as a kind of new secondary energy sources gradually in fields such as electric motor car (EV), electric bicycle, electric tool, portable type electronic products, and more and more important use is arranged in daily life.Compare with nickel-cadmium cell, Ni-MH battery, lead-acid battery, lithium ion battery has specific energy height, light, the discharge platform advantages of higher of volume, but but exists the over-charging difference and cross the shortcoming of putting poor performance.The Chinese patent balancing energy device of high-capacity lithium battery group " be applied to connect " (patent No. is CN02289111.0) provides a kind of balancing energy device of the high-capacity lithium battery group that is applied to connect, it mainly is to form the high-capacity lithium battery group by the mode of series connection, and between two lithium batteries of series connection, be provided with a balancing energy device, and this balancing energy device can be obtained the voltage of two lithium batteries and compare its accurate position, when the voltage that detects two lithium batteries has vertical parallax, promptly synchronously by this balancing energy device, the electric weight of the lithium battery that voltage is higher is carried toward voltage lower, make the electric weight equilibrium of two lithium batteries, and reach the state that energy even distributes.
Summary of the invention
Goal of the invention of the present utility model provides a kind of safe and reliable, simple lithium-ions battery of assembling procedure.
Goal of the invention of the present utility model is solved by following technical proposals: lithium-ions battery, comprise several monomer lithium ion batteries and the transition wiring board that is connected with battery pole ear in plastic casing, the plastic casing, the transition wiring board is provided with both positive and negative polarity and discharges and recharges pole and pad, the transition wiring board with pad that battery pole ear is connected on have slot, in the positive and negative slot that the lug of the both positive and negative polarity of battery inserts respectively, insulate with insulating material between the lug, and exposed lug partly is welded on the pad of transition wiring board; The transition wiring board is provided with some plug wire holes, and pad is connected with plug wire hole, and plug wire hole is connected with the equalizing circuit module with the protective circuit module; Cell is connected in series by pad and plug wire groove.
In one embodiment of the invention, the transition wiring board is provided with row's plug wire hole, and plug wire hole connects protective circuit module and equalizing circuit module.As preferably, the number of plug wire hole is (cell number+1).The protective circuit module is implemented over-charge protective and crosses to put protection to each cell, and the equalizing circuit module is carried out balanced discharge simultaneously to three cells of detected ceiling voltage wherein, to guarantee the consistency between each cell.
In another embodiment of the present invention, the transition wiring board is provided with two row's plug wire holes, and wherein row's plug wire hole connects the protective circuit module, and other row's plug wire hole connects the equalizing circuit module.As preferably, the number of single plug wire hole is (cell number+1).One row is used for the protective circuit module and gathers the monomer battery voltage signal; each cell is implemented over-charge protective and crosses to put protection; an other row is used for the equalizing circuit module and gathers the monomer battery voltage signal; and three cells of detected ceiling voltage are wherein carried out balanced discharge simultaneously, to guarantee the consistency between each cell.
The protective circuit module is carried out over-charge protective, is crossed and put protection, short circuit (overcurrent) protection and overheat protector each cell.In charging process, when certain joint cell reached over-charge protective voltage, the protective circuit module was moved through after certain time of delay, disconnects charge circuit, avoids battery phenomenon to occur overcharging, thereby avoids occurring potential safety hazard.After overcharging protection action, battery pack still can be discharged, when battery power discharge when this joint monomer battery voltage is lower than the over-charge protective recovery voltage, battery pack can be charged again again.In discharge process, when reaching, certain joint cell put protection during voltage, and the protective circuit module is moved through after certain time of delay, disconnects discharge loop, avoids battery phenomenon to occur putting, thereby avoids battery permanent damage to occur.Served as put protection action after, battery pack still can be charged, and puts when protecting recovery voltage when batteries charging to this joint monomer battery voltage is higher than, battery pack can be discharged again again.Move after short circuit or over-current phenomenon avoidance appear in load, and certain time of delay is passed through in short circuit (overcurrent) protection, avoid battery pack potential safety hazard to occur, after short circuit (overcurrent) phenomenon was got rid of, it is normal that the protective circuit module is recovered again.When the excess temperature phenomenon takes place in charge and discharge process battery pack, the protective circuit module can disconnect charging and discharging circuit according to the temperature of being gathered, and avoid occurring potential safety hazard.
The equalizing circuit module is carried out equilibrium to each cell.In charging process, give the equalizing circuit module for power supply by charger.The equalizing circuit module is divided into two kinds of balanced ways, a kind of is the overall process equilibrium: in charging process, the equalizing circuit module is gathered each monomer battery voltage signal in real time, three batteries discharge to ceiling voltage, when the difference of ceiling voltage in the battery and minimum voltage was lower than certain numerical value, the equalizing circuit module stopped balanced discharge.Another kind of for to decide electric voltage equalization: in charging process, after assembled battery total voltage reaches set point, the equalizing circuit module is gathered each monomer battery voltage signal, three batteries discharge to ceiling voltage, when the difference of ceiling voltage in the battery pack and minimum voltage was lower than certain numerical value, the equalizing circuit module stopped balanced discharge.
Electric bicycle uses the lithium-ions battery product in charging process; after if certain joint cell reaches over-charge protective voltage; charger stops charging; but charger still continues to the equalizing circuit module for power supply; guaranteeing that the equalizing circuit module continues battery balanced, thereby guarantee the consistency between each cell.
That lithium-ions battery product of the present utility model has is safe and reliable, the simple advantage such as efficient of assembling procedure.
