Lead carbon accumulator cover

Technical Field

The utility model relates to a power storage battery field, in particular to lead carbon battery cover.

Background

The lead-acid storage battery has been created for over 150 years so far, and the application field of the storage battery is very wide. Due to the mature technology, the cost performance and safety of the power type lead-acid storage battery are still one of the first choice of the electric vehicle at the present stage. Increasing the energy density of storage batteries is a requirement for rapid development of storage battery products in China and national policy regulations. At present, the connection mode among the single cells of the lead-acid storage battery mainly comprises the welding of a bridge post, and the secondary welding is carried out after the bus bar of the storage battery is welded to connect each single cell in series. The size of the welding area of the bridge post has a determining factor for large-current charging and discharging. Meanwhile, the lead consumption weight of the battery is increased to a certain extent by the bridging pole, and the energy density of the battery is reduced.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: to the problem that exists among the prior art, the utility model provides a lead-carbon storage battery cover has got rid of bridge utmost point post, and simple structure can practice thrift the battery inner space, increases battery capacity, reduces plumbous consumption, improves energy density and volumetric specific energy, and the busbar directly links the structure and reduces heavy current conduction route simultaneously, is favorable to the heavy current conduction.

The technical scheme is as follows: the utility model provides a lead-carbon accumulator cover, which comprises a cover body and a plurality of single lattices arranged on the lower surface of the cover body, wherein a positive pole column hole and a negative pole column hole which are vertically penetrated are arranged in two single lattices at the opposite ends of the cover body; a transverse through bus bar groove is formed between every two adjacent pairs of the single lattices, the bus bar grooves which are arranged in the adjacent two transverse through ways are separated by partition walls, and a glue groove which is longitudinally through and is communicated with the bus bar grooves is formed between the adjacent two single lattices; and the cover body is also provided with a plurality of vertically-penetrating acid adding holes.

Furthermore, glue avoiding grooves are respectively arranged right above the bus bar grooves and at opposite positions of the upper surface of the cover body. The arrangement of the glue avoiding groove enables the depth of the bus bar groove to be shallow, and when glue is injected into the glue groove, the glue groove is communicated with the bus bar groove, so that the glue groove and the bus bar groove can be filled with less glue; and certain plastic consumption can be saved during the manufacturing of the cover body.

Furthermore, bus bar clearance grooves are respectively formed in the inner walls of the two single lattices provided with the anode column holes and the cathode column holes. There is not the busbar groove in two cells of seting up anodal post hole and negative pole post hole, when the installation busbar, directly install the busbar in these two cells, because the needs of busbar are with the welding of cell inner wall, so, the length of busbar will be wider than the width of cell a little usually, like this, just need set up the busbar on these two cell inner walls and keep away the dead slot to guarantee that the busbar can install smoothly in these two cells, and be in the same place busbar and cell inner wall welding.

Furthermore, handle grooves are respectively formed in two sides of the upper surface of the cover body. The arrangement of the handle groove is convenient for manually opening the battery cover.

Preferably, each acid adding hole is respectively opened in a plurality of unit lattices. The acid adding holes are communicated with the single lattices, so that the acid can be directly added into the battery through the acid adding holes during acid adding.

Preferably, each of the bus bar slots has a positive electrode and a negative electrode, the positive electrodes and the negative electrodes of two adjacent bus bar slots arranged transversely and straightly are arranged oppositely, and the positive electrodes and the negative electrodes of two adjacent bus bar slots arranged longitudinally are arranged oppositely.

Has the advantages that: the lead-carbon storage battery cover of the utility model has the advantages that the structure does not use the bridge pole, the structure is simple, the internal space of the battery can be saved, the battery capacity is increased, the lead consumption can be reduced without the bridge pole, and the energy density and the volumetric specific energy are improved; meanwhile, the bus bar direct-connection structure reduces a large-current conduction path, and is favorable for large-current conduction.
