Abstract
The invention provides a method for forming high-capacity battery pack from cluster battery units. The high-capacity battery pack comprises batteries, conducting strips, connection boards and the like; a plurality of single batteries are connected in parallel to form a composite battery unit structure; and a plurality of composite battery units are connected in series and in parallel to form a battery pack with higher capacity. The invention realizes the method of composing a high-capacity battery pack by using low-capacity battery packs and greatly reduces the production cost of the battery pack. The composite battery module structure can conveniently assemble a high-capacity battery pack from a plurality of composite battery units, and can also conveniently disassemble a high-capacity battery pack into composite battery units, thereby providing convenience for maintaining the battery pack and replacing the batteries.
Description
Technical field:
The present invention relates to the method that a kind of combined battery unit constitutes large-capacity battery pack, be particularly useful for the method for the large-capacity battery pack of many cell series connection and parallel connection.
Background technology:
Present large-capacity battery pack all is to use high capacity cell by connecting and being parallel together, and high capacity cell is used for the manufacturing technology complexity and causes its production cost very high, and promotion and application have a lot of limitation.
Summary of the invention:
The objective of the invention is: invent and a kind ofly have low cost of manufacture and combination and fractionation and make things convenient for the battery combination method.
Technical scheme of the present invention is: use the experimental process battery cell by connecting conducting strip all batteries to be connected in parallel, constitute a female battery unit, again several female battery units are combined large-capacity battery pack that meets the demands of formation by series connection and mode in parallel.
The further technical scheme of the present invention is: the end at female battery unit has a conducting strip that connects each stand battery, the elastic tongue piece that equates with sub-number of battery cells is arranged on the conducting strip, each can contact the negative pole of battery above the elastic tongue piece, can contact the positive pole of another series connection with it battery below, when conducting strip is cascaded top battery and following battery, also all batteries with this battery unit are connected in parallel, there are several conduction lugs in the outside of conducting strip, when several female battery units are placed in same horizontal plane, the conduction lug of adjacent female battery unit overlaps and links together, and female battery unit of putting at same horizontal plane is connected in parallel.
In the technique scheme, described sub-battery can be circular cell, also can be the square individual battery.
Advantage of the present invention is: the combined battery modular structure that a kind of novel high capacity cell is provided, it uses the experimental process battery cell to constitute a female battery unit by parallel way, again these female battery units are combined by series connection and mode in parallel and constituted a battery pack with high voltage and high power capacity, the combined battery modular structure has realized that the use small-capacity cells is combined into high capacity cell, reduced the production cost of battery pack significantly, this combined battery modular structure also can be easily with the synthetic large-capacity battery pack of dividing of several primary and secondary stacks of cells, also can easily large-capacity battery pack be split as combined battery unit, the maintenance of very convenient battery pack and battery altering.

Embodiment:
The present invention is further described below in conjunction with drawings and Examples:
The present invention is made of battery 1, conducting strip 2 and connecting plate 3 etc., and conducting strip 2 uses the rubber-like sheet metal through punch forming, and the elastic tongue piece 21 of position punching press at corresponding each battery center has 8 conduction lugs 22 around the conducting strip.Each elastic tongue piece 21 can contact the negative pole 13 of top battery, can contact simultaneously the positive pole 12 of following another battery, up and down two batteries are cascaded, and when conducting strip 2 was cascaded top battery and following battery, all batteries that also will this layer were connected in parallel.Connecting plate 3 uses insulating material to make, connecting plate on corresponding battery cathode 11 (profile) and below the positive pole 12 (profile) of battery the positioning table 31 of self-contained battery is all arranged, each battery is fixed in the middle of the positioning table of connecting plate, has so just constituted a female battery unit that 16 cylindrical batteries constitute.
The combined method of battery pack is: respectively with two groups of female battery units 43 and 41,44 and 42 vertical pendulums are put together, two female battery units of vertically putting make up and down by conducting strip 2, and two groups of female battery units are cascaded, and then their horizontal pendulums are put together, two groups of female battery units 43 and 44 that level is put, 41 and the 42 elastic conduction lugs 22 by conducting strip 2 contact, and female battery unit that two levels are put is connected in parallel; Two groups of female battery units, the two groups of female battery unit parallel battery of connecting have been formed.Battery pack top and followingly have conducting strip 2 to constitute battery pack positive electrode 51 and battery pack negative electrodes 52 respectively so just constituted a battery pack of being made up of four female battery units, realized that two groups of 32 battery parallel connections carry out the series connected battery group again.Make to use the same method, can make up any battery series connection and any battery parallel battery as required.
As shown in Figure 3, making uses the same method forms female battery unit with 16 rectangular cells 13, re-uses four groups of female battery units 43 and 41,44 and 42 and forms two groups of female battery units, the two groups of female battery unit parallel battery of connecting.(more clear for view, as to have omitted a conducting strip 2 and a connecting plate 3 above female battery unit 54)
