In some cases, the battery cells can also be used directly, that is, the battery may not include a casing, which is not limited here.
[0073] In a battery, when there are multiple battery cells, the multiple battery cells can be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells are connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells is accommodated in a box; of course, the battery can also be a battery module formed by connecting multiple battery cells in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in a box.

In this way, when the battery is assembled, the module formed by the battery cell only needs to be connected to the electrical output structure, saving the time required to install the signal acquisition component, output electrode and protective cover separately, thereby improving the assembly efficiency of the battery. The module formed by the battery cell refers to a combination of battery cells that need to be connected in series and parallel.

The protective cover 34 covers the part of the output electrode 33 extending out of the side of the insulating plate 31, and the protective cover 34 is installed on the insulating plate 31. The output electrode 33 includes an electrical output terminal 331, and the electrical output terminal 331 extends out of the side of the insulating plate 31, and the protective cover 34 covers at least part of the electrical output terminal 331.
[0085] The insulating plate 31 refers to a plate made of insulating materials such as plastic, bakelite, ceramics, etc. The insulating plate 31 is not only used to insulate and separate the battery cell 200 from the conductive components in the battery, but also used to support other components of the electrical output structure 30 to achieve the integration of these components for the installation and use of the electrical output structure 30.
[0086] The signal acquisition component 32 refers to a component used to collect status information of the battery cell 200.

For example, it can provide insulation protection for the electrical output terminal 331, reduce the risk of short-circuit connection between the electrical output terminal 331 and other terminals, improve safety, and also provide a certain dust-proof effect for the electrical output terminal 331. The protective cover 34 can be made of materials such as plastic and ceramic. The protective cover 34 is mounted on the insulating plate 31 to support the protective cover 34 through the insulating plate 31, so that the protective cover 34 is integrated on the insulating plate 31. Since the electrical output terminal 331 of the output electrode 33 is mainly connected to an external circuit, the protective cover 34 can be covered on at least a portion of the structure of the electrical output terminal 331 to protect it.
[0091] By integrating the signal acquisition component 32, the output electrode 33 and the protective cover 34 with the insulating plate 31, they can be manufactured and assembled separately, and integrated assembly of incoming materials can be achieved.

Therefore, when in use, only the electrical output structure 30 needs to be installed, that is, the signal acquisition component 32, the output electrode 33 and the protective cover 34 can be assembled together, which saves the time required for separately installing the signal acquisition component 32, the output electrode 33 and the protective cover 34 in the module formed by the battery cell 200, thereby improving the assembly efficiency of the battery.
