[0024] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0025] [Example 1]

[0026] A battery with visual lighting effects, such as Figure 1 , including a battery main body 1 and a battery outer cover 2, the battery main body 1 is generally a 48V aluminum shell battery pack, the battery outer cover 2 is made of plastic, and a light-transmitting portion 21 is provided on the battery outer cover 2. The light-transmitting portion 21 is arranged at the inclined position on both sides of the battery outer cover 2 and extends along the length direction. A light strip 5 is provided between the battery main body 1 and the battery outer cover 2, and the light strip 5 is arranged near the light-transmitting portion 21. A wireless module mounting position 22 is provided on the battery outer cover 2, and the wireless module 3 is installed at the wireless module mounting position 22.

[0027] Furthermore, if Figure 2 A fixed base plate 4 is provided between the battery outer cover plate 2 and the battery body 1. The fixed base plate 4 is used to connect the battery outer cover plate 2 and the battery body 1. The fixed base plate 4 and the battery outer cover plate 2 are connected by bolts. Figure 3 , the battery outer cover 2 is provided with a reinforcing rib structure 23 and a number of bolt holes, such as Figure 4 、 Figure 7 The fixed base plate 4 is connected to the battery body 1 by a snap-fit ​​structure 7. The snap-fit ​​structure 7 includes two plug-in plates arranged on the fixed base plate 4 and a slot arranged on the battery body 1, making the overall assembly of the battery convenient.

[0028] There are two light strips 5, which are installed obliquely on the fixed base plate 4. The wireless module mounting position 22 is a groove structure. The fixed base plate 4 is also provided with a groove for installing the wireless module 3. The wireless module 3 is installed in the space formed between the two grooves. The wireless module mounting position 22 is preferably set at the end position of the battery outer cover 2 to facilitate wiring and prevent the wireless module 3 from being completely located between the light strips on both sides, thereby reducing the impact of the heat from the light strips on the wireless module 3. Optionally, a groove extending in the same direction as the light-transmitting portion can be set around the light-transmitting portion of the battery outer cover 2 to increase the contact area between the airflow and the battery outer cover 2 during riding to assist in heat dissipation.

[0029] The battery body 1 is provided with a light strip through hole 11 for providing a passage for the light strip connecting wire. The light strip adopts RGB light strip to form the atmosphere light of the battery pack. Figure 5 The light strip is directly controlled by the battery pack's BMS. PWM signals can be used to adjust the light's color, brightness, lighting duration, and various states. This allows for diverse effects, such as shooting star and breathing lighting. Due to the intuitive visibility of the light strip, several important battery pack information can be displayed through lighting effect definitions, such as the current battery charge and battery failure status. Preferably, all vehicle electrical components (loads), including the battery, use CAN communication, which provides fast response and strong signal interference resistance.

[0030] The wireless module 3 can adopt a wireless communication module such as AIRTAG, GPRS wireless communication module or a wireless communication positioning module. The wireless module 3 can be powered by the battery body 1 or has its own independent battery power supply. The design of the plastic battery cover 2 solves the problem of poor signal of the wireless module due to metal shielding. The wireless module can be placed in the battery pack to increase the anti-theft and traceability functions of the EBIKE (electric bicycle) bottom-mounted battery pack.

[0031] The light strip allows users to visualize the vehicle's status from a distance and quickly determine the battery's current state, increasing the efficiency of battery diagnostics and enhancing the shared e-bike experience. The light strip also includes ambient lighting effects, adding a new riding experience.

[0032] An electric bicycle, such as Figure 6 , including the above-mentioned battery with visual lighting effect, the battery is pluggable and installed on the lower tube 6. Preferably, the battery outer cover 2 partially protrudes from the lower tube 6 to avoid affecting the performance of the wireless module 3 and improve the visual effect of the light strip.

[0033] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations and modifications may be made to the embodiments of the present invention without departing from the principles described.
