However, in the prior art, the cell diameter of the wound-type sealed lead-acid battery is 50 mm to 60 mm, which greatly limits the capacity of the wound-type sealed lead-acid battery. Production
At the same time, the wound-type sealed lead-acid battery is a single wound cell installed in a cylindrical battery case, the process of cell winding and battery assembly is complicated, and it is difficult to carry out mechanized production
The battery is large in size, heavy in weight, and low in specific energy
The above factors lead to the complex structure, high cost and poor consistency of the existing winding-type sealed lead-acid batteries, making it difficult to popularize and use

The invention relates to a sealed lead-acid battery with multiple horizontal winding cells. The sealed lead-acid battery comprises a battery case, wherein a battery cover is arranged on the top surface of the battery case; a through hole is formed in the middle of the battery cover and is internally provided with a sealing valve; the two sides of the sealing valve are respectively provided with a pole; one end of each pole is exposed while the other end of each pole extends into the battery case; more than two layers of horizontal winding cells are arranged in the battery case; and negative electrodes of the winding cells in the battery case are connected with one another in parallel by a left bus bar and then electrically connected with one pole, and positive electrodes of the winding cells in the battery case are connected with one another in parallel by a right bus bar and then electrically with connected the other pole. According to the invention, the mechanized mass production of winding-type sealed lead-acid batteries with capacities ranging from 0.5 Ah to 500 Ah can be achieved. The sealed lead-acid battery provided by the invention is simple in structure, reliable in performance and low in cost.
Description
technical field [0001] The invention relates to the technical field of lead-acid storage batteries, in particular to a sealed lead-acid storage battery with multi-winding batteries placed horizontally. Background technique [0002] Compared with flat-plate lead-acid batteries, wound-type sealed lead-acid batteries have higher starting power, faster charging speed and longer service life, which makes the development of lead-acid batteries have broad prospects. However, in the prior art, the cell diameter of the wound-type sealed lead-acid battery is 50 mm to 60 mm, which greatly limits the capacity of the wound-type sealed lead-acid battery. Production. At the same time, a wound-type sealed lead-acid battery is a single wound cell installed in a cylindrical battery case. The process of cell winding and battery assembly is complicated and it is difficult to mechanize production. The volume of the battery is large, the weight is large, and the specific energy is low. The abo...
