Embodiment 1

[0034] Such as Figure 1 to Figure 12As shown, a bipolar lead-acid battery includes a tank body 8, six sets of pole groups 9 and eight separators, the pole groups 9 are placed in the tank body 8, and the partition is located between the tank body 8 and the pole group 9, And between the pole groups 9, the pole groups 9 are arranged in two rows and three columns. The positive unipolar plates 98 and the negative unipolar plates 97 in the same group of pole groups 9 are all wrapped with diaphragms and stacked alternately according to the positive and negative properties. The liquid realizes the electrical connection between the positive and negative plates in the same pole group. In the pole group 9 of the first row, the positive unipolar plate 98 in the left pole group 9 is electrically connected to the negative unipolar plate 97 in the middle pole group 9 through the bipolar plate 91 one by one, and the middle pole The positive unipolar plate 98 in the group 9 is electrically c...

Embodiment 2

[0037] The pole groups 9 are arranged in one row and six columns, the bipolar plate 91 deviates from the midpoint position of the sides of the positive unipolar plate 98 and the negative unipolar plate 97, and the tabs of the pole plates in the six-column pole group 9 are stacked in a diagonal dislocation ,Such as Figure 13 As shown, the bipolar plate 91 between the pole group 9 in the second row and the pole group 9 in the first row is higher than the positive unipolar plate 98 and the waistline of the negative unipolar plate 97, while the pole group 9 in the second row is separated from the pole group 9 in the first column. The bipolar plates 91 between the three rows of pole groups 9 are lower than the same distance between the positive unipolar plate 98 and the negative unipolar plate 97, and so on, between the third and fourth row of pole groups 9, and the fifth and sixth The bipolar plate 91 between column pole group 9 is higher than positive unipolar plate 98, negative...

Abstract

The invention discloses a bipolar lead-acid battery. The bipolar lead-acid battery comprises a groove body, multiple plate groups and a plurality of partitions, wherein the plate groups are arranged in the groove body, the partitions are arranged between the groove body and the plate groups and among the plate groups, the plate groups are arranged in two rows and at least two lines, positive monopole plates and negative monopole plates in the same plate group are laminated in a staggered way according to positive and negative attributions, in the same row of plate groups, the positive monopole plate in the plate group is electrically connected with negative monopole plate in the adjacent plate group by a bipolar plate in one-to-one correspondence, in the plate group at an outer line in the rows and lines of the plate groups, the positive monopole plate in the plate group is electrically connected with the negative monopole plate in the adjacent plate group in the same line by a busbar, in the plate group at the other outer line in the rows and lines of the plate groups, the positive monopole plate in the plate group is electrically connected with a positive busbar, the negative monopole in the adjacent plate group in the same line is electrically connected with a negative busbar, and each positive monopole plate or each negative monopole plate is only directly connected with one of the bipolar plate and the busbars.

Description

technical field [0001] The invention relates to a lead-acid storage battery and an electric vehicle using the battery, more specifically, it relates to a bipolar lead-acid storage battery and an electric vehicle using the battery. Background technique [0002] Since its birth, lead-acid battery has been widely developed due to its high cost performance, high safety reliability and recyclability, and has occupied more than 80% of the secondary power supply market. However, lead-acid batteries also have the disadvantages of low specific capacity and low specific energy. Lead-acid batteries generally have multiple pole groups, and each pole group is equipped with a positive bus bar and a negative bus bar, and the bus bars between each pole group are connected together by n-shaped brackets, and the amount of bus bars is large. The lead consumption and resistance are also large, and the current flows from the plate to the bus bar and then passes through the bridge to another pol...
