The battery is used to power small power vehicles such as electric bicycles, electric scooters, and electric motorcycles. The battery includes a battery cell module 1, a module inner shell 2, and an outer shell assembly 3, such as Figure 5 As shown, the battery cell module 1 is arranged in the module inner shell 2, and then arranged in the outer shell assembly 3. The battery adopts an inner and outer double shell design, and the structural strength is stable.
[0042] The battery module 1 includes a T-shaped battery 11, a T-shaped acquisition communication circuit board 12 and a wire port 13. Figure 5 and Figure 7 As shown. The T-shaped battery cell 11 refers to the arrangement of the battery cells so that the overall shape is approximately T-shaped, and this arrangement can improve space utilization. The T-shaped acquisition and communication circuit board 12 integrates the original acquisition board and the communication board into one, and can perform signal acquisition and communication at the same time. The size of the T-shaped acquisition and communication circuit board 12 is adapted to the size of the T-shaped battery cell 11, so that when the T-shaped acquisition and communication circuit board 12 is electrically connected to the side of the T-shaped battery cell 11, it will not increase the overall size of the T-shaped battery cell 11, making the structure of the battery cell module 1 compact and improving space utilization.
[0043] The wire port 13 is electrically connected to the T-shaped battery cell 11, and is used to lead out the positive and negative electrodes of the T-shaped battery cell 11, so as to facilitate electrical connection with the connector 7 through wires. The wire port 13 is arranged at the corner of one side of the T-shaped battery cell 11 and the T-shaped acquisition communication circuit board 12, so that the overall size of the battery cell module 1 is not increased, and the structure is compact. The wire port 13 is arranged at the corner of one side of the T-shaped battery cell 11 and the T-shaped acquisition communication circuit board 12, so that the T-shaped structure becomes a structure with a step on one side, and one side of the upper half extends to the outside of one side of the lower half.
[0044] In this embodiment, a plurality of rows of sawtooth-shaped pole ears 121 and a plurality of device holes 122 are provided on the T-shaped acquisition communication circuit board 12. Figure 6 As shown. The sawtooth-shaped pole lugs 121 are respectively arranged on the top surface of the lateral upper structure and on both sides of the longitudinal lower structure.

At the same time, the structure arranged opposite to each other on the left and right sides enables the first inner shell 21 and the second inner shell 22 to maintain a shape with the battery module 1. The shape can make the battery structure compact as a whole and improve the space utilization.
[0048] In this embodiment, the battery module 1 is a T-shaped structure. The first inner shell 21 and the second inner shell 22 are both configured to have the same shape as the battery module 1.
