Abstract
The utility model provides a lithium ion battery voltage dynamic verification of group and accent weighing apparatus device, includes voltage collector, protection shield and battery charging outfit, voltage collector's the charge -discharge terminal of voltage acquisition terminal and lithium cell link to each other, the charge -discharge terminal positive negative pole that passes through protection shield and battery charging outfit link to each other, the positive negative pole of charge -discharge terminal and battery charging outfit between establish ties and be provided with the alligator clip, the utility model discloses following beneficial effect has: the method is established ties anchor clamps in the circuit ingeniously, has solved the problem that can't see battery real -time status in the group battery fills the discharge process through voltage collector, can see in real time that which group battery appears for the topic, and for the maintenance group battery provides accurate reliable data, this testing arrangement easy operation is convenient, data display clarity directly perceived to can observe real -time data, the invention of this equipment makes the dynamic electric core each item index down of observation realize.
Description
Technical field
The utility model relates to a kind of Li-ion batteries piles voltage check device, is specifically related to a kind of voltage check device lithium ion battery battery being compressed into Mobile state display.
Background technology
Along with the development of science and technology and the raising of people's environmental consciousness, lithium ion battery is more and more applied in the Working Life of people, due to the characteristic of Li-ion batteries piles, be assembled into high-tension battery pack to need to use branched battery core connection in series-parallel to use, but lithium ion battery production technology is also immature now, be difficult to the consistency ensureing product, therefore to carry out combo to battery core before connection in series-parallel assembling is carried out to single battery core and (namely select voltage, the battery core that internal resistance is consistent or close), but several the even indices of tens battery cores selecting through combo are not completely the same, in use, through charge and discharge cycles repeatedly, still there will be the phenomenon that voltage is inconsistent, after ceiling voltage in a Battery pack and minimum voltage difference reach certain numerical value, protection can be protected automatically, stop Li-ion batteries piles work, this will use inconvenience for causing user.For extending battery pack useful life and making it be in optimum Working, voltage need be carried out to battery pack and adjust weighing apparatus (namely higher to voltage in Battery pack battery core is discharged, and the battery core lower to voltage carries out benefit electricity).The tune weighing apparatus device of current use is most adjusts weighing apparatus for static (battery pack is neither charged and also do not discharged); but battery pack is all be in dynamic (battery is in charge or discharge) during Li-ion batteries piles baffle protection battery; voltage numerical value under the dynamic and stalic state of battery core is different; there is the amplitude of variation of often propping up cell voltage when dynamically transferring static state to also different; the voltage seen during the static balancing of such dependence, with being different time dynamic, is difficult to accurately find problem and repair Li-ion batteries piles so only rely on static tune to weigh.
Summary of the invention
For addressing the aforementioned drawbacks, the utility model provides a kind of and detects Li-ion batteries piles dynamic electric voltage and adjust the device weighed, thus can under the state of Li-ion batteries piles discharge and recharge, detect the voltage often propping up battery core, detect data more accurate, thus electric voltage equalization can be carried out to battery pack, thus battery pack is made to be in best operating state; Detect battery pack problem place in time, facilitate the later stage to repair in time, improve the fail safe that battery pack uses.。
For achieving the above object; the utility model is by the following technical solutions: a kind of Li-ion batteries piles voltage detection of dynamic and adjust weighing apparatus device; comprise voltage collector, baffle and charging device; the voltage acquisition terminal of described voltage collector is connected with the discharge and recharge terminal of lithium battery; described discharge and recharge terminal is connected with the both positive and negative polarity of charging device by baffle, has been arranged in series crocodile clip between described discharge and recharge terminal and the both positive and negative polarity of charging device.
Further, described crocodile clip is have the copper of conducting function or aluminum crocodile clip.
Compared with prior art, the utility model has following beneficial effect: fixture is connected in series in circuit by the method dexterously, to solve in battery set charge/discharge process cannot by voltage collector see battery real-time status problem, can see which battery pack appears as topic in real time, for maintenance battery pack provides data accurately and reliably, this testing apparatus is simple to operation, data visual clear display, and observable real time data, the invention of this equipment makes observation dynamically descend battery core indices to be achieved.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and apparent following the drawings and the specific embodiments are only a kind of forms of expression of the technical program, also can obtain other specific embodiments according to the technical program.
A kind of low-voltage circuit insulating blanked clamper of Fig. 1 electrical block diagram.
Embodiment
As shown in Figure 1; a kind of Li-ion batteries piles voltage detection of dynamic and tune weighing apparatus device; comprise voltage collector, baffle and charging device; the voltage acquisition terminal of described voltage collector is connected with the discharge and recharge terminal of lithium battery; described discharge and recharge terminal is connected with the both positive and negative polarity of charging device by baffle; be arranged in series crocodile clip between described discharge and recharge terminal and the both positive and negative polarity of charging device, described crocodile clip is have the copper of conducting function or aluminum crocodile clip.
Obviously, above-mentioned execution mode is only one of them embodiment of the present utility model, and any simple modifications on this basis all belongs to protection range of the present utility model.
