Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Examples

A lead-acid storage battery, which is applied to an automobile, as shown in fig. 1 and 2, comprising: the battery pack comprises a shell 1 and six single batteries 2 arranged in the shell 1; the outer side of the single battery 2 is provided with an isolation housing 3, the side of the isolation housing 3 is provided with a connecting part 4, two adjacent single batteries 2 are connected in series through the connecting part 4, and the structure of the single battery is referred to the prior art and is not described herein.

In the above embodiment, as shown in fig. 2, the connecting member 4 includes: a plurality of first lugs 41, electric wires (copper connectors) 42; both ends of the electric wire (copper connector) 42 are connected to the adjacent first lugs 41, respectively, so that the positive electrodes and the negative electrodes of the adjacent two unit batteries 2 are connected.

In the above embodiment, as shown in fig. 1, the top of the case 1 is penetratingly provided with the positive terminal 5 and the negative terminal 6.

In the above embodiment, as shown in fig. 1, the positive electrode of the unit cell 2 located at the edge is connected to the second lug 7 through the electric wire (copper connector) 42, the second lug 7 is fixed to the positive terminal 5 through the bolt 8, the negative electrode of the unit cell 2 located at the edge is connected to the second lug 7 through the electric wire (copper connector) 42, and the second lug 7 is fixed to the negative terminal 6 through the bolt 8.

In order to avoid winding too many wires in the shell 1, the anodes and the cathodes of the plurality of single batteries 2 are alternately arranged, that is, when the single batteries 2 are sequentially placed in the shell, the polarities of one side of each single battery 2 are sequentially arranged as the anode, the cathode, the anode and the cathode, and the polarities of the other side of each single battery 2 are sequentially arranged as the cathode, the anode, the cathode and the anode.

In the above embodiment, the isolation housing 3 is made of plastic, which is a common plastic material in the prior art, and is light and has a certain heat insulation effect.

In the above embodiment, the capacity of each unit cell 2 is the same.

In the above embodiment, the internal resistance of each unit cell 2 is the same.

In the above embodiment, the voltage of each single battery 2 is the same and is 2V, and six single batteries 2 are connected in series to obtain a 12V lead-acid battery.

Because the lead-acid storage battery in the prior art is formed by a plurality of single batteries at one time, the inconsistency of the capacity, the internal resistance and the voltage among the single batteries is easy to occur, after the battery is used for a period of time, the single batteries with large capacity are not charged enough, the single batteries with low capacity are charged too much, the discharge is the situation that the single batteries with low capacity are over-discharged, the difference of the internal resistance of each single battery is increased, the charging receiving capacity is inconsistent, the voltage drop is increased when the battery is used, the battery can not be used quickly, therefore, in the production process of the single battery 2 in the embodiment, the capacity, the resistance and the voltage of each single battery are matched and then are connected in series to form a battery with completely consistent internal resistance, therefore, the service life of the lead-acid storage battery in the embodiment is longer than that of the battery produced by the traditional method by more than 1.5 times.
