Thus, the cell assembly 54 accommodated in the accommodating cavity can be tightly attached to the inner wall of the housing assembly 51, so that the structure of the battery 5 is more compact and the space utilization inside the housing assembly 51 is high. Although the figures of the embodiments of the present disclosure show that the electric core assembly 54 and the case assembly 51 are both rectangular parallelepiped in shape, the electric core assembly 54 and the case assembly 51 are not limited thereto, for example, the electric core assembly 54 and the case assembly 51 may also be both cylindrical in shape.

Fig. 7 is a partial cross-sectional view of a battery attached to a right housing in an embodiment of the present disclosure. Referring to fig. 3 and 7, the communication module 53 includes a housing, and a communication circuit board 532 and an antenna 533 mounted inside the housing, the communication circuit board 532 and the BMS board 540 being electrically connected by a cable 534, the antenna 533 being provided on the communication circuit board 532 and communicating with the server. The communication principle is as follows: the detection module is used for detecting the status information of the battery 5 and sending the status information to the BMS board 540, the BMS board 540 generates a status signal according to the received status information and sends the status signal to the communication circuit board 532 through the cable 534, and the communication circuit board 532 communicates with the server through the antenna 533 and then sends the status signal of the battery 5 to the server. With such a configuration, when the electric bicycle 100 having the battery 5 is used as a shared electric bicycle, an operator of the shared electric bicycle can know the health condition of the battery 5 according to the status signal of the battery 5 received by the server, and then can judge whether the battery 5 needs to be maintained and replaced according to the health condition of the battery 5, so as to ensure that the battery 5 can always work normally.

It will be appreciated that the server may also communicate with the mobile terminal to communicate the health of the battery 5 to the user's mobile terminal. Therefore, the user can know the safety condition of the battery 5 and accordingly select the electric bicycle 100 to be ridden, and safety accidents caused by the fact that the user rides the electric bicycle 100 with the battery 5 having potential safety hazards are avoided.

As shown in fig. 7, the housing includes an upper housing 530 and a lower housing 531 which are butted to each other, and the upper housing 530 and the lower housing 531 enclose a mounting space for mounting the communication circuit board 532 and the antenna 533. Alternatively, the lower housing 531 may be a first box with an open top wall, and the upper housing 530 may be a second box with an open bottom wall, the first box being in butt joint with the second box; alternatively, the lower case 531 may be a box structure having an open top wall, and the upper case 530 may be a cover plate covering the open top wall of the box structure. The connection mode of the upper housing 530 and the lower housing 531 is not limited to adhesion, and preferably, the upper housing 530 and the lower housing 531 are connected by a detachable connection mode such as a screw joint or a snap joint, so that the installation space can be opened to facilitate maintenance of the communication module 53.

Preferably, the lower case 531 and the upper case 530 are made of plastic. Therefore, compared with the case where the upper case 530 and the lower case 531 are both made of metal, the influence of metal on the signal transmitted by the antenna 533 can be avoided, and the unimpeded transmission of the signal is facilitated, so that the transmission quality of the signal is improved.

The antenna 533 may be any one or more of a GSM antenna, a 3G antenna, a 4G antenna, or a 5G antenna, so that the communication circuit board 532 and the server may communicate through a 2G network, a 3G network, a 4G network, and/or a 5G network. Of course, in some examples, the antenna 533 may further include a GPS antenna for acquiring the position of the battery 5 and sending the position signal to the server, so that the operator can know the specific position of the electric bicycle 100 according to the position signal received by the server.

In an implementation manner of the present disclosure, the communication module 53 further includes a communication power supply portion, which is accommodated in the installation space and connected with the communication circuit board 532 to supply power to the communication circuit board 532. Thus, when the power supply is disabled due to a failure of the battery 5, the communication module 53 can still communicate with the server to report the failure of the battery 5 to the server, as compared to when the battery 5 supplies power to the communication module 53. Wherein, the communication power supply portion can be the lithium cell, also can be button cell.

Further, the communication circuit board 532 is located above the communication power supply portion, and the antenna 533 is located above the communication circuit board 532. That is, the communication power supply portion, the communication circuit board 532, and the antenna 533 are stacked from bottom to top. In this way, the antenna 533 is closer to the sky than the communication feeding portion, which is advantageous for signal transmission and for avoiding interference of the communication feeding portion and the communication circuit board 532 with signals.

In order to further improve the communication capability of the communication module 53, the communication module 53 is disposed above the battery pack assembly 54, so that the communication module 53 is located at the top end of the whole battery 5, and the communication module 53 is closer to the sky, which is more favorable for signal transmission, and at the same time, is favorable for avoiding interference of the battery 5 with signals.

In this embodiment, a slot is further provided on an inner wall of either one of the left housing 510 and the right housing 511, and the communication module 53 is inserted into the slot. Therefore, the slot can limit and constrain the communication module 53, so that the communication module 53 is stably installed in the accommodating cavity to avoid the communication module 53 from shaking in the accommodating cavity.

In summary, the battery 5 of the embodiment of the present disclosure can transmit the status information of the battery 5 to the server, and when the electric bicycle 100 having the battery 5 provides the sharing service, the operator can know the status of the battery 5 according to the information received by the server, and manage and maintain the battery 5 according to the known status, so that the safety of the battery 5 can be guaranteed all the time.

Specifically, the slot is formed in a space between the top of the left or right case 510 or 511 and the top end of the battery 5. The following description will be given only by taking the case where the slot is formed on the inner wall of the right housing 511 as an example, and it will be apparent to those skilled in the art after reading the following technical solutions that the slot is formed on the inner wall of the left housing 510.

Illustratively, the slot may extend in a direction perpendicular to the mating direction of the left housing 510 and the right housing 511, and both ends of the slot are connected to the opposite inner sidewalls of the right housing 511, respectively. Further illustratively, as shown in fig. 4, the slot may be further connected with an inner sidewall of the right housing 511 facing the left housing 510, and the slot extends in parallel with a mating direction of the left housing 510 and the right housing 511. Specifically, the inner side wall of the right housing 511 is provided with a cartridge 5113, one side of the cartridge 5113 facing the left housing 510 is provided with an opening for inserting the communication module 53, and the slot is defined by the cartridge 5113 and the inner wall of the right housing 511.

That is, the hanger 5411 is located on one side of the flange and the hose 544 is bent to extend upwardly on the other side of the flange. Wherein the opening of the overhang 5411 can be disposed toward the flange or can be disposed away from the flange. The flange can thereby guide the cable 534 such that the cable 534 passing out through the cable channel extends along the flange to the hose 544.

Based on the above, an exemplary routing manner of the cable 534 is as follows: one end of the cable 534 is connected with the communication module 53, the other end of the cable 534 extends downwards from the top of the battery pack 54 and is clamped in the clamping groove 5410, then the cable 534 passing through the clamping groove 5410 passes through the wire passage and extends to one side of the flange facing the battery pack 54, the cable 534 extends along the side wall of the flange and passes through the hose 544, the cable 534 passing through the hose 544 bends upwards along the hose 544 and extends into the battery pack 54 through the wire hole, and the cable 534 is connected with the BMS board 540.
