Description
Technical field
The utility model relates to a kind of Modularized lithium battery group, specifically provides the Modularized lithium battery group that a kind of alternative lead-acid battery parallel connection uses.
Background technology
At present in electric bicycle field, lithium battery group adopts one group of lithium battery group or adopts the series connection of polylith modular battery to use with the voltage and the capacity requirement that reach electric bicycle requirement when being applied to electric bicycle, these two kinds of lithium battery groups also exist respective defect respectively when alternative lead-acid battery, for the situation of one group of lithium battery group, its face shaping, size and lead-acid battery have a great difference, can not exchange use very well.When using for the series connection of polylith lithium battery module, its total capacity is decided by total capacity certainly will be caused to reduce by one piece of lithium battery module that capacity is minimum.
Summary of the invention
The utility model just for the deficiencies in the prior art, and provides a kind of Modularized lithium battery group of alternative lead-acid battery parallel connection use,
In order to achieve the above object, the technical scheme that the utility model is taked is:
The Modularized lithium battery group that a kind of alternative lead-acid battery parallel connection uses; comprise at least two lithium batteries; each lithium battery comprises the outer cover body of drain pan and upper cover composition; cover on described and be provided with positive terminal and negative terminal; it is characterized in that: the positive terminal of at least two described lithium batteries is linked together by positive lead; described negative terminal is linked together by negative lead, is provided with the baffle connecting both positive and negative polarity binding post in described outer cover body.
The safety valve be also provided with for pressure release in outer cover body is covered on described, described safety valve comprises the safety valve base of through upper cover, safety valve base is provided with the safe rubber cap of valve control, described safety valve top relative on cover the safety valve cover plate be provided with for hiding safety valve.
The beneficial effects of the utility model it is possible to substitute various lead-acid battery completely, and versatility is good.Modular construction, the capacity changing battery is very simple, and longer service life, maintenance cost is lower.
Accompanying drawing explanation
Fig. 1 is the utility model structural perspective.
Fig. 2 be in the utility model Fig. 1 A-A to cutaway view.
In figure: 1, outer cover body 2, drain pan 3, upper cover 4. positive terminal 5. negative terminal 6. safety valve base 7. valve control safe rubber cap 8. safety valve cover plate 9. negative lead 10. positive lead 11. baffle.
Embodiment
From accompanying drawing 1 and accompanying drawing 2; the utility model comprises at least two lithium batteries; each lithium battery comprises the outer cover body 1 of drain pan 2 and upper cover 3 composition; described upper cover 3 is provided with positive terminal 4 and negative terminal 5; the positive terminal 4 of at least two described lithium batteries is linked together by positive lead 10; described negative terminal 5 is linked together by negative lead 9, is provided with the baffle 11 connecting both positive and negative polarity binding post in described outer cover body 1.
Described upper cover 3 is also provided with for the safety valve to pressure release in outer cover body 1, described safety valve comprises the safety valve base 6 of through upper cover 3, safety valve base 6 is provided with the safe rubber cap 7 of valve control, and the relative upper cover 3 in described safety valve top is provided with the safety valve cover plate 8 for hiding safety valve.
When reality uses; the shell of the utility model lithium battery group is processed into prop up battery case with the lead-acid battery list wanting to substitute identical or close; lithium battery group is assembled into by the mode of parallel connection; the voltage of this lithium battery group is consistent with the voltage that application apparatus requires; have baffle 11 to protect this battery pack in this lithium battery group, the capacity of this battery pack does as far as possible when this outer cover body 1 can load greatly.
Lithium battery group is put into outer cover body 1, and the both positive and negative polarity of lithium battery group is connected with negative terminal 5 by the positive terminal 4 after baffle 11 respectively on shell.
The utility model carries out capacity increasing again by mode in parallel, and during use, because its shell is identical or close with the lead-acid battery shell that will substitute, voltage is consistent with equipment requirement, uses so can substitute lead-acid battery completely.And be not limited to the number of assembling, the relative capacity adding battery pack, battery cell wherein breaks down, be connected in parallel owing to adopting, output voltage does not reduce, and the entirety that can not affect battery pack uses.
In addition, the utility model embodiment is only the embodiment of the utility model the best, for a person skilled in the art, belongs to the apparent change of the utility model design, all belongs within the utility model protection range.
