The first battery cell (13) has a first terminal (131) and a second terminal (132), and the second battery cell (14) has a first contact point (141) and a second contact point (142), wherein the first contact point (141) and the second contact point (142) are electrically connected with the first terminal (131) and the second terminal (132) respectively. The upper plate has two holes (121,122), and the first terminal (131) and the second terminal (132) pass through the two holes (121,122) respectively when the upper plate (12) covers the upper opening (111).

Description

Battery structure

The present invention relates to a battery structure, and more particularly to a lightweight battery structure.

Background technique

General automotive lead-acid batteries have long been standard equipment for starting batteries for vehicles such as automobiles and locomotives. They have the advantages of large electromotive force, wide operating temperature, simple structure, mature technology and low price, but they also have weights, etc. Disadvantages.

In particular, automotive lead-acid batteries usually have a capacity of about 65 ampere-hours, and weigh about 15 to 20 kilograms. Their weight is heavy, which has a certain degree of influence on the fuel consumption of vehicles such as cars and locomotives. Under the trend of environmental protection and fuel economy, lead-acid batteries have been gradually eliminated. Summary of the invention

The prior art lead-acid battery has the problem of weight, so the present invention provides a lightweight battery structure, comprising: a casing having an upper opening, the upper opening opening an inner chamber; a first battery The unit has a first terminal and a second pile; a second battery unit has a first contact and a second contact, and the first contact and the second contact are respectively electrically connected The first pile head and the second pile head; an upper plate having two holes, and the first pile head and the second pile head respectively pass through the two holes when the upper plate is closed.

The lightweight battery structure provided by the invention has two or more battery cells with different charging and discharging characteristics, which can effectively reduce the weight and output the voltage corresponding to the specifications of the commercially available vehicle, thereby achieving the effect of saving fuel and environmental protection. .

1 is a perspective view of a first preferred embodiment of the present invention, and FIG. 2 is an exploded view of the first preferred embodiment of the present invention. FIG. A perspective view of a preferred embodiment. The present invention provides a battery 100 structure comprising: a housing 11, an upper plate 12, a first battery unit 13, a second battery unit 14, and a base 15. It should be noted that those skilled in the art will recognize that the battery cells in the battery are not limited to two, and may be two or more.

The outer casing 11 has an upper opening 111 and is covered with an upper plate 12, and the upper opening 111 is internally provided with an inner chamber 112. The first battery cell 13 has a first pile head 131 and a second pile head 132. In the present embodiment, the material of the first pile head 131 and the second pile head 132 is copper, but the invention is not limited thereto. Further, in the present embodiment, the first battery cell 13 is a lithium iron battery. Lithium iron batteries are usually lithium iron phosphate (LiFePO batteries, which do not contain valuable elements such as cobalt, and because of the abundant resources of the earth such as phosphorus, lithium, iron, etc., there is no shortage of materials.

The second battery unit 14 has a first contact 141 and a second contact 142. The first contact 141 and the second contact 142 are electrically connected to the first pile head 131 and the second pile head 132, respectively. In the present embodiment, the second battery cell 14 is a lead acid battery. It should be particularly noted here that the first battery cell 13 and the second battery cell 14 have different charge and discharge characteristics.

The upper plate 12 has two holes 121, 122. In addition, when the upper plate 12 is covered by the upper opening 111, the first pile head 131 and the second pile head 132 of the first battery unit 13 pass through the two holes 121, 122, respectively.

The base 15 is disposed at the bottom of the inner chamber 112 of the outer casing 11, so that the first battery unit 13 and the second battery unit 14 are placed on the base 15, as shown in FIG. 3, but the invention is not limited thereto. The second embodiment may also place the first battery cell 23 of the battery 200 on the base 25, as in Figure 4, or in other embodiments, the second battery cell is placed on the base.

In summary, the battery 100 of the present invention is a modification of the past battery for a vehicle, which can be simply placed in the engine compartment 91 of the vehicle 9, as shown in FIG. Also. The battery 100 conforms to the specifications of a commercially available vehicle regardless of the size of the casing, the capacity or the output voltage. However, it is known to those skilled in the art that the battery 100 specifications can also be appropriately changed, and can be placed in a traffic vehicle such as a locomotive or an electric wheelchair. Whether it is a lying or standing type, it can be provided according to these traffic vehicles. The installation space is rounded up.
