Embodiment 1

[0032] Embodiment 1: as figure 1 , Figure 4 As shown, a horizontal battery includes a battery box body 1 and a battery box cover 2 . The battery case body is surrounded by a bottom plate and four side plates 1a, 1b, 1c, 1d of front, rear, left and right. The front and rear side panels are parallel to each other, and the left and right side panels are parallel to each other. The front side panel is perpendicular to the left side panel.

[0033] Such as figure 1 , image 3 As shown, there are at least two series-connected pole group monomers 7 inside the battery box body, and the pole group monomers are composed of several positive plates 71a and several negative plates 71b arranged alternately through separators.

[0034] The positive and negative plates include a grid 74 , and the grid includes a number of criss-crossing horizontal ribs 741 and vertical ribs 742 . The tabs on the positive or negative plate include the following two forms;

[0035] Form 1: The tabs are ...

Embodiment 2

[0050] Embodiment 2: as Figure 7 As shown, a horizontal battery, the body of the battery box is provided with a pole group monomer, and the pole group monomer is composed of a number of positive plates and a number of negative plates alternately arranged through separators, in the pole group monomer: the positive plate The tabs of the pole group are located on the same side of the pole group monomer, the tabs of the negative plate are located on the same side of the pole group monomer, and the tabs of the positive plate and the tabs of the negative plate are located on the opposite sides of the pole group monomer; the positive plate Partition sealing strips are provided on the lugs of the negative plates, and partition sealing strips are also provided on the tabs of the negative plates; and the partition sealing strips on each positive plate are connected in sequence to form a positive partition plate, and the partition sealing strips on each negative plate are connected in tu...

Embodiment 3

[0052] Embodiment 3: as Figure 7 , Figure 8 As shown, a horizontal battery, the battery box body is provided with at least two pole group monomers connected in parallel, the pole group monomers are composed of a number of positive plates and a number of negative plates alternately arranged through separators, the same pole group In the monomer: the tabs of the positive plate are located on the same side of the pole group monomer, the tabs of the negative plate are located on the same side of the pole group monomer, and the tabs of the positive plate and the tabs of the negative plate are located on opposite sides of the pole group monomer side; the lug of the positive plate is provided with a partition seal, and the tab of the negative plate is also provided with a partition seal; and the partition seals on each positive plate are connected in turn to form a positive partition, and the seals on each negative Partition sealing strips are connected in sequence to form a negat...

Abstract

The invention discloses a horizontal battery, which comprises a battery box body and at least two single plate groups connected in series. In the same single plate group, tabs of positive plates and tabs of negative plates are positioned on the two opposite sides of the single plate group; partition sealing strips are arranged on the tabs of the positive and negative plates, the partition sealing strips on the positive plates are sequentially connected into a positive partition plate, and the partition sealing strips on each negative plate are sequentially connected into a negative partition plate. In every two adjacent single plate groups connected in series, internal pouring sealant grooves are formed, and the tabs of the positive and negative plates in the same internal pouring sealant groove are connected in a welding manner; the internal pouring sealant grooves are filled with a pouring sealant. The horizontal battery has the beneficial effects that the problem of influence on the service life of the battery due to the fact of mixing between single battery cells or influence on a sealing effect caused by wax seal damage can be effectively solved; the operational performance and reliability of the horizontal battery can be improved.

Description

technical field [0001] The invention belongs to the technical field of storage batteries, in particular to a horizontal battery and an electric vehicle. Background technique [0002] Lead-acid batteries are widely used in many fields because of their low price, mature technology and large monomer capacity. The traditional lead-acid battery plates are only designed with one tab, and then the same positive plate or negative plate tabs in the same pole group are welded together through the bus bar, and then the bus bar is extended, or connected to the adjacent single The body is welded, or the terminal protrudes to the outside of the battery case. Confluence excludes the conduction effect, and has no good effect on the capacity and life performance of the battery. On the contrary, it increases the internal resistance of the battery. [0003] On the other hand, the pole group monomers of the current horizontal battery are formed by alternately arranging a number of positive pl...
