Description
Technical Field
The utility model relates to a battery technical field specifically is battery connection structure.
Background
The positive and negative plates of the existing lead-acid storage battery are connected by adopting a single electrode lug of a single electrode group and a plurality of positive plates to be cast-welded or welded into a positive busbar and a single electrode lug of a plurality of negative plates to be cast-welded or welded into a negative busbar, and the single storage battery is assembled by the positive plates, the diaphragms and the negative plates. The single pole plates are connected in parallel by adopting a single-pole lug welding or mould cast welding mode and then connected in series with each single battery pack. The lead consumption is large, the gravimetric specific energy is low, the internal resistance of the storage battery is large by adopting a bus bar and bridging series connection, and the large-current discharge performance is poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide novel battery connection structure, its lead consumption is few, the gravimetric specific energy improves, the internal resistance reduces, and heavy current discharge performance improves.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
novel battery connection structure, including a plurality of utmost point crowd, include positive plate and negative plate in every utmost point crowd, the positive plate has positive lead alloy grid, the negative plate has negative lead alloy grid, and is adjacent positive lead alloy grid and negative lead alloy grid of utmost point crowd adopt two or more than two utmost point ear or lead muscle strip to link to each other.
Preferably, the tabs comprise positive tabs and negative tabs, the positive tabs and the positive lead alloy grids are integrally formed, the negative tabs and the negative lead alloy grids are integrally formed, and the positive tabs and the negative tabs are connected in a welding mode.
Preferably, the tab is integrally formed with the positive lead alloy grid and the negative lead alloy grid.
Preferably, the lead ribs are integrally formed with the positive lead alloy grid and the negative lead alloy grid.
Preferably, the integral molding is casting molding, punching molding, net pulling molding, net punching molding or weaving molding.
The utility model has the advantages that:
1. the utility model discloses positive lead alloy grid and negative lead alloy grid between the adjacent utmost point crowd of battery group adopt two or more than two utmost point ears or lead muscle strip to link to each other, cancel the busbar of conventional battery and stride the bridge, the current circuit is shorter, and the battery internal resistance also corresponding reduction, heavy current discharge performance also obviously improve, make battery heavy current discharge capacity improve more than 20%.
2. The internal resistance of the lead-acid storage battery manufactured and produced by using the connecting structure can be reduced by more than 20 percent, the voltage limiting of the storage battery charging can be reduced, the water loss of the storage battery in the charging process is reduced, and the service life of the storage battery is prolonged.
3. Because no bus bar is arranged, the lead consumption of the battery is correspondingly reduced by more than 5 percent (the lead is obviously saved as the specification and the model of the storage battery are larger), and the weight ratio energy of the storage battery is correspondingly improved.
