Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described for specific embodiment.
Fig. 1 show the schematic diagram of the single pole group of the lead-acid accumulator of the present invention, and pole group is by some positive plates 1 and negative pole
Plate 2 and AGM dividing plates 3 replace stacked offset and form, and every positive plate 1 is formed with anode ear 4, and every negative plate 2 is formed with negative pole
Ear 5, all anode ears connect a positive bus 6, all negative electrode lugs through cast welding jointly through cast welding in single pole group
Connect a negative bus-bar 7 jointly.
Fig. 2 show the pole group of the lead-acid accumulator of the present invention, and each single pole group is by some positive plates 1 and negative plate
2 and AGM dividing plate 3 replaces stacked offset and forms, and the positive bus 6 and negative bus-bar 8 of the first single pole group A are located at respectively the
The upper side and lower side of one single pole group, the positive bus 9 and negative bus-bar 7 of the second single pole group B are located at the described second list
The downside and upside of individual pole group；All anode ears connect jointly through cast welding on first single pole group A positive bus 6 and phase
The all negative electrode lugs of the single pole group B of neighbour second are connected through the negative bus-bar 7 that cast welding connects jointly by the way of series connection, and first
All negative electrode lugs are through all positive poles of the pole group C single with the adjacent 3rd of negative bus-bar 8 that cast welding connects jointly on single pole group A
Ear is connected through the positive bus 10 that cast welding connects jointly by the way of series connection；To reduce the conductive resistance that welding is caused,
Top positive and negative electrode bus-bar connected mode is connected using U-shaped cast welding, and bottom positive and negative electrode bus-bar connected mode adopts direct-connected one
Body formed cast welding connection, top bus-bar is integrally arranged in straight line, and bottom bus-bar is integrally arranged in straight line, institute
There are the positive bus and negative bus-bar of single pole group symmetrical relative to pole group center, in battery-operated engineering, electric current
Passed through by upper and lower two parts bus-bar, bus-bar is not only the part that electric current collects, be also the part of divergence, by converging
The electric current conducted on stream row is spread out of on the grid of every pole plate, either Battery formation, or the work of the lead accumulator of chemical conversion
During work, electric current is all transmitted on the every pole plate lug of pole group by bus-bar, then by grid conduct to pole plate each
Region.Up and down bus-bar symmetrical structure can make electric current from upper and lower two parts while conducting again by battery top and the bottom bus-bar
To on every pole plate, allow homogeneous current distribution, to reach reduction electrolyte stratification, top and the bottom brown lead oxide is caused in discharge process
The process for changing into lead sulfate is more balanced so that it is more balanced that battery top and the bottom release capacity；And in charging process, electric current is same
When by the bus-bar of top and the bottom so that the reaction that the lead sulfate of top and the bottom is converted into spongy lead is more balanced, to reach
Negative plate reduces the purpose of sulfuration.
Fig. 3 show the battery general assembly drawing of the present invention, the pole group shown in Fig. 2 is fed into battery case 11, battery cover
Including upper lid 12 and lower cover 13, upper lid 12 and lower cover 13 are formed with the bus-bar for accommodating positive bus and negative bus-bar and hold
Storage tank 23 under groove 22 and bus-bar is put, filling epoxy sealing in storage tank 23 under storage tank 22 and bus-bar on bus-bar
In the sealing of the upper lid 12 of glue realization and lower cover 13 and battery case 11 and battery case 11 between each single lattice and upper lid 12 and lower cover 13
Sealing, upper lid 12 and lower cover 13 individually operate infusion epoxy resin fluid sealant, the positive pole on the first single pole group A to conflux
The negative bus-bar 7 of 6 pole group Bs single with adjacent second of row is located on bus-bar in storage tank 22, negative on the first single pole group A
The positive bus 10 of the pole group C single with the adjacent 3rd of pole bus-bar 8 are located under bus-bar in storage tank 23, all bus-bar portions
In part embedment fluid sealant, it is to avoid burn into is vibrated or high current ruptures, sealing technology is carried out in battery assembling, sealed reliable
Property it is high, vibration resistance performance is strong, is not in the phenomenon collaborated between single lattice, therefore self discharge is little, favourable to battery consistency, together
When, because the conductive components such as bus-bar are imbedded in fluid sealant, using transmission of heat by contact, heat transfer rate is fast, and temperature rise is little, to the big of battery
Electric current charges and quick charge is extremely beneficial.The positive plate and the negative plate are fixed on institute by the upper lid and the lower cover
State in battery case.
The height design size of upper lid 12 and lower cover 13 is pressed and " gone up after lid 12 and lower cover 13 and the closure of battery case 11, upper lid 12
Fit with pole group with lower cover 13 " principle be designed, that is, the positive plate and negative plate of pole group is by upper lid 12 and lower cover 13
Be fixed in battery case 11, so design can avoid, unnecessary free state electrolyte is arranged at pole group bottom, this partial electrolyte liquid by
In pole plate is not reached, the reaction with pole plate in the group of pole is almost not involved in, but in charging process, sulfuric acid can be generated, sulfuric acid is easy
Towards the diffusion of low-density free state electrolyte, cause bottom free state density of electrolyte more and more higher, and participate in pole plate reaction
Sulfuric acid amount is fewer and feweri, affects lead accumulator work；In addition, lead accumulator is used on the instruments such as electric motor car, due to using ring
Border road out-of-flatness is easily produced to produce and jolted, 13 pairs of poles of upper lid 12 and lower cover all rise one " load-bearing " effect, it is to avoid cause
Pole group is hanging, it is to avoid bus-bar ruptures.
The battery of patent of the present invention compares the advantage of conventional lead storage cells：Change in structure makes battery internal polar plate upper and lower
Portion's active material utilization is balanced, and plate active material utilization rate is high so that electric current is logical from the upper and lower two pieces of regions of lead accumulator
Cross, allow homogeneous current distribution, reduce acid layering to reach, it is to avoid positive and negative pole plate top and the bottom brown lead oxide, sulfuric acid lead content differ
Cause, balanced active material utilization, reduce cell decay, extend lead accumulator service life.
