[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that when an element is described as "connected" to another element, it can be directly connected to the other element, or there may be one or more intermediate elements between them. In the description of the embodiments of this utility model, "multiple" means two or more. If "first," "second," etc. are mentioned, they are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0023] Please see Figure 1 As shown, this utility model provides an intelligent power indicator bar for an energy storage device, including a communication module 100, a control module 200, multiple driver chips 300, and multiple indicator lights 400. The control module 200 is connected to the communication module 100 and communicates with a host computer through the communication module 100. The multiple indicator lights 400 are used to indicate the remaining power and charging / discharging status of the energy storage device. The negative terminals of the multiple indicator lights 400 are connected to the driver chips 300. The DIN pins of the multiple driver chips 300 are connected to the I / O ports of the control module 200. The multiple driver chips 300 are used to control the on / off state and color switching of the multiple indicator lights 400 according to the signals transmitted by the control module 200.

[0024] The multiple indicator lights 400 are multi-color RGB LEDs, and the number of RGB LEDs is multiple. The light colors of the RGB LEDs include: blue, green, and red. The RGB LEDs also have a breathing flashing state, which is used to display the breathing flashing state of the corresponding light color according to the zeroing operation signal.

[0025] The control module 200 controls the flashing of multiple RGB LEDs to present different lighting effects. The control module can control the color changes of multiple RGB LEDs, making the red RGB LEDs light up alone, or the green and blue RGB LEDs light up alone, or making two or three of the red, green, and blue RGB LEDs flash alternately, thus achieving a variety of different color changes and thus achieving a variety of lighting effects to meet the needs of users.

[0026] In one embodiment of this utility model, the indicator light 400 is used to display the power level of the energy storage device. When the power level of the energy storage device reaches a preset stage, the driver chip 300 controls the RGB LED beads to emit the corresponding color according to the signal transmitted by the control module 200. Specifically, the power level of the energy storage device is displayed by four LEDs. When a certain stage is reached, the corresponding indicator light illuminates, and each light represents 25% of the power level.

[0027] In another embodiment of this utility model, the energy storage device includes a current detection unit for collecting the current of the energy storage device's power supply. A control module is connected to the current detection unit and controls RGB LEDs to emit corresponding colors according to the amplitude of the current to display the energy storage device's power level. Different current amplitudes correspond to different colors. Specifically, the RGB tri-color LEDs display eight colors (red, orange, yellow, green, cyan, blue, purple, and white) through software, each representing a different power level. The power level can be further subdivided, with each color representing 12.5%. Through the above method, this application can more specifically display the true power level of the power bank without increasing the number of LEDs.

[0028] In this invention, the intelligent power indicator light strip for the energy storage device also indicates the device's operating status and whether it is charging. Operating status includes network connectivity, connection status, abnormal status, idle status, etc. Multiple indicator lights display different colors or turn on / off depending on whether the energy storage device is in a connected, networked, idle, or abnormal state, allowing users to quickly determine whether the energy storage device's power supply is available. When the energy storage device is charging / discharging, each indicator light is controlled to perform a multi-color light cyclic flashing action within a preset time. Specifically, when the energy storage device is charging, it can display a colorful effect based on the charging signal to attract customer attention.

[0029] In another embodiment of this utility model, the intelligent power indicator strip of the energy storage device further includes a first DC / DC module and a second DC / DC module. The first DC / DC module and the second DC / DC module are respectively connected to an external power supply, used to convert the external power supply into a first voltage and a second voltage to power multiple indicator lights, a control module, and multiple driver chips. Specifically, the first DC / DC module is connected to a 24V external power supply, used to convert the 24V external power supply into a 12V power supply to power multiple indicator lights, and the second DC / DC module is connected to a 24V power supply, used to convert the 24V power supply into a 3.3V power supply to power the control module and the communication module, so that multiple RGB LEDs display corresponding light colors, thereby achieving various lighting effects.

[0032] In one embodiment of this invention, the communication module is a RS485 communication module.

The RS485 interface is a standard for data communication, primarily used for effective signal transmission over long distances and in environments with high electronic noise. The RS485 interface operates based on differential signal transmission. When sending data, the transmitter converts the TTL level to a differential signal and transmits it through lines A and B. The receiver receives these differential signals and converts them back to TTL level.
