[0038] As shown in Figures 1 to 12, this application provides a specific embodiment of an energy storage terminal.

[0039] An energy storage terminal, referring to Figure 1, includes a battery module 100, a voltage regulation module 200, and a POE module 300. The POE module 300 includes a POE interface 310 and a POE management circuit 320. The battery module 100 is connected to the POE management circuit 320 through the voltage regulation module 200. The POE management circuit 320 is connected to the POE interface 310. The POE interface 310 is used to connect to an external host device 10 for power transmission and / or data interaction with the external host device 10.

[0040] Specifically, referring to Figure 1, the battery module 100 can be a battery module, which combines multiple battery cells together to form an integrated battery module, thereby achieving a larger capacity of energy storage and providing higher voltage and current output; the voltage adjustment module 200 is used to obtain the output voltage of the battery module 100 and adjust the output voltage of the battery module 100 to the corresponding required output voltage to supply power to the external host device 10.

[0041] Furthermore, referring to Figure 1, the POE module 300 is used to transmit power and data. The POE module 300 includes a POE interface 310 and a POE management circuit 320. The POE interface 310 can be connected to the external host device 10 via an Ethernet cable to enable power supply to the external host device 10 and data interaction between the external host device 10 and the energy storage terminal. This method only requires a single Ethernet cable to transmit data and power, and no additional power lines are required when installing the device, making the installation simpler.

[0042] Among them, the external host device 10 can be a Starlink satellite antenna device, or it can be an e-government system, outdoor monitoring device, intelligent lighting system, wireless monitoring system, network base station, industrial automation system, medical equipment, network intelligent transportation system, etc.

[0043] Currently, when the main unit is used in the field, its matching AC adapter needs to be connected to the AC output port of an external power source such as an outdoor power supply in order to be powered on. That is, the battery DC power is first converted to AC power output through an external power source such as an outdoor power supply, and then the input AC power is converted to DC power output through the matching AC adapter to the main unit. This power supply method involves multiple conversions between DC and AC, resulting in large energy loss and low energy utilization throughout the power supply process.

[0044] In this embodiment, an energy storage terminal is designed, including a battery module 100, a voltage regulation module 200, and a POE module 300. The POE module 300 includes a POE interface 310 and a POE management circuit 320. The battery module 100 is connected to the POE management circuit 320 through the voltage regulation module 200. The POE management circuit 320 is connected to the POE interface 310, which is connected to an external host device 10 for power transmission and / or data interaction. In this scheme, the battery module 100 supplies power to the POE management circuit 320 after DC voltage conversion by the voltage regulation module 200, and supplies power to the external host device 10 through the POE interface 310. No energy storage inverter is required, reducing the DC-AC-DC conversion process, resulting in less power loss and higher energy utilization in the power supply path. By setting up a POE interface to connect to the external host device for power transmission and / or data interaction, the wiring of the equipment is effectively simplified, reducing installation and maintenance costs.

[0045] In one embodiment, referring to FIG2, the POE module 300 further includes a LAN interface 330, which is connected to the POE management circuit 320 for connecting to an external router device 20. When the energy storage terminal does not have a built-in router device, a LAN interface 330 can be added to the POE module 300. The POE module 300 is connected to the external router device 20 through the LAN interface 330, thereby connecting to external electronic devices to realize data interaction between the energy storage terminal and the external electronic devices. When the energy storage terminal is connected to the external host device 10 through the POE interface 310 and the Ethernet cable, and then connected to the external router device 20 through the LAN interface 330, the data of the external host device 10 can be transmitted to the external electronic devices.

[0046] In one embodiment, referring to Figures 3 and 4, the energy storage terminal further includes a main control module 400. The voltage adjustment module 200 includes a voltage regulating unit 210 and a feedback control unit 220. The first input terminal of the voltage regulating unit 210 is connected to the battery module 100 to obtain the output voltage of the battery module 100. The output terminal of the voltage regulating unit 210 is connected to the POE management circuit 320 to boost or buck the output voltage of the battery module 100 and output the corresponding voltage to the POE management circuit 320. The input terminal of the feedback control unit 220 is connected to the output terminal of the voltage regulating unit 210 to obtain the output voltage of the voltage regulating unit 210. The output terminal of the feedback control unit 220 is connected to the second input terminal of the voltage regulating unit 210 to provide a feedback voltage to the voltage regulating unit 210, thereby achieving a stable voltage output. The control terminal of the feedback control unit 220 is connected to the main control module 400. The feedback control unit 220 can be turned on under the control of the main control module 400 to pull down the feedback voltage.

[0047] The voltage regulating unit 210 outputs a first electrical energy with a first voltage value to the POE management circuit 320 under the control of the main control module 400. The feedback control unit 220 is turned on and pulls down the feedback voltage under the control of the main control module 400, thereby outputting a second electrical energy with a second voltage value to the POE management circuit 320.

[0048] In one embodiment, the voltage range of the first voltage value is 43V to 52V; and the voltage range of the second voltage value is 53V to 61V.

[0049] Preferably, the first voltage value is 48V and the second voltage value is 57V, to meet the needs of mainstream Starlink satellite antenna equipment on the market.

[0050] In one embodiment, referring to Figures 3 and 4, the voltage adjustment module 200 further includes an on / off switch 230, and the feedback control unit 220 includes a resistor R41 and a capacitor C28. One end of the resistor R41 is connected to the output terminal of the voltage regulation unit 210, and the other end of the resistor R41 is connected to one end of the capacitor C28. The other end of the capacitor C28 is connected to the voltage feedback terminal FB, which is connected to the second input terminal of the voltage regulation unit 210 to provide a feedback voltage. The feedback control unit 230 also includes resistors R42, R45, R46, and R47. One end of the resistor R42 is connected to the output terminal of the voltage regulation unit 210, and the other end of the resistor R42 is connected to one end of the resistor R45. The other end of the resistor R45 is connected to one end of the resistor R46. The other end of 46 is grounded. Resistors R47 and R46 are connected in parallel for voltage division. The feedback control unit 230 also includes resistors R43 and R44. One end of resistor R43 is connected to the voltage feedback terminal FB, and the other end of resistor R43 is connected to one end of resistor R44. The other end of resistor R44 is connected to the on / off switch 230. The control terminal of the on / off switch 230 is connected to the main control module 400. When the main control module 400 controls the on / off switch 230 to close, the voltage regulating unit 210 outputs a first voltage value to the POE management circuit 320. When the main control module 400 controls the on / off switch 230 to open, resistors R43 and R44 pull down the feedback voltage of the voltage feedback terminal FB, so that the voltage regulating unit 210 outputs a higher second voltage value to the POE management circuit 320.

[0051] In one embodiment, the on / off switch 230 can be a switching element such as a transistor, MOSFET, optocoupler, or relay. In this embodiment, referring to FIG4, the on / off switch 230 is a transistor Q12. The base b of the transistor Q12 is connected to the main control module 400, the collector c of the transistor Q12 is connected to the resistor R44 in the feedback control unit 220, and the emitter e of the transistor Q12 is grounded. Furthermore, a resistor R48 is provided between the base b of the transistor Q12 and the main control module 400, and a resistor R73 is provided between the base b of the transistor Q12 and the emitter e of the transistor Q12.

[0052] When the required voltage for the external host device is the first voltage value, the main control module 400 controls the transistor Q12 to turn off, and the power output terminal of the voltage regulating unit 210 directly outputs the first voltage value to the POE management circuit 320. When the required voltage for the external host device is the second voltage value, the main control module 400 controls the transistor Q12 to turn on, the voltage feedback terminal FB of the feedback control unit 220 is pulled low, the feedback voltage input to the second input terminal of the voltage regulating unit 210 becomes smaller, and thus a larger second voltage value is output to the POE management circuit 320.

[0053] In one embodiment, referring to FIG5, the energy storage terminal further includes a POE control button 500. The POE control button 500 is connected to the main control module 400 to input button control commands to the main control module 400. The main control module 400 can turn on or off the power output of the POE module 300 according to the button control commands of the POE control button 500. When the system is powered on, the power output of the POE module 300 can be turned on or off by pressing the POE control button 500.

[0054] Furthermore, the main control module 400 can also switch the output voltage of the POE module 300 according to the button control command of the POE control button 500. In the system power-off state, the switching mode can be entered by pressing and holding the POE control button 500. In the switching mode, the main control module 400 can control the on / off switch 230 to switch the output voltage of the POE module 300 by pressing the POE control button 500. This design can prevent users from switching arbitrarily and avoid accidentally switching the mode to a higher second voltage value output when the voltage required by the connected external host device is a lower first voltage value, thereby avoiding damage to the host device.

[0055] In one embodiment, referring to Figures 5 and 6, the POE module 300 further includes a protection circuit 340, the power input terminal of which is connected to the voltage regulating unit 210, and the power output terminal of which is connected to the POE management circuit 320.

[0056] Specifically, referring to Figures 5 and 6, the protection circuit 340 includes an interface J1, a TVS diode D1, and a common-mode inductor L1. Pin 1 of the interface J1 is connected to the power output terminal of the voltage regulating unit 210, pin 2 of the interface J1 is grounded, the negative terminal of the TVS diode is connected to pin 1 of the interface J1, the positive terminal of the TVS diode D1 is connected to pin 2 of the interface J1, the input terminal of the common-mode inductor L1 is connected to the TVS diode D1, and the output terminal of the common-mode inductor L1 is connected to the PoE management circuit 320.

[0057] Further, referring to Figures 5 and 7, the PoE management circuit 320 includes a network transformer TM1 and multiple gas discharge tubes (see G1, G2, G3, G4, G5, G6, G7 and G8 in Figure 3). One side of the network transformer TM1 is connected to the LAN interface 330, and the other side of the network transformer TM1 is connected to the PoE interface 310 for data interaction.

[0058] In one embodiment, referring to FIG8, in order to be compatible with different battery packs, the energy storage terminal further includes a power input port 600 and a PWM control module 700.

[0059] Specifically, referring to Figure 8, the PWM control module 700 includes a PWM control circuit (refer to Figure 9) and an operational amplifier circuit (refer to Figure 10). The input terminal of the PWM control circuit is connected to the power input port 600, and the output terminal of the PWM control circuit is connected to the battery module 100. The control terminal of the PWM control circuit is connected to the main control module 400 through a PWM bridge driver. The input terminals (II+1, II-1) of the operational amplifier circuit are connected to the input terminals of the PWM control circuit to sample the input current and obtain the sampled voltage. The output terminal of the operational amplifier circuit is connected to the main control module 400 to transmit the sampled voltage to the main control module 400. The main control module 400 can control the PWM control circuit to output different charging currents to the battery module 100 according to the sampled voltage.

[0060] In one embodiment, referring to FIG11, the system further includes multiple USB ports and a USB control button 810. The multiple USB ports include at least one first USB port 820 for outputting high-power electrical energy to power external electronic devices, and a second USB port 830 for outputting low-power electrical energy. The second USB port 830 is a normally open and uninterrupted power interface. The USB control button 810 is connected to the main control module 400 for inputting button control commands. The main control module 400 can control the first USB port 820 and the second USB port 830 to open or close according to the button control commands. When the first USB port 820 is open, the second USB port 830 is powered on and is in a normally open and uninterrupted power state. The first USB port 820 is powered on when an external electronic device is connected, and is powered off after a period of time when the charging current of the external electronic device is less than a preset current, in order to save energy consumption.

[0061] The USB control button 810 can be used to control both the opening and closing of the USB interface and the maximum charging current of the battery module. When the system is off, pressing and holding the USB control button 810 will enter the charging power setting mode to set the maximum charging power of the current battery module. After setting, the main control module 400 controls the PWM control module 700 to adjust the maximum charging current to output the corresponding charging current to the battery module 100. When the system is on, pressing the USB control button 810 will enable the USB output function, keeping the second USB interface 830 constantly open and enabling the insertion recognition function of the first USB interface 820. When no external electronic device is connected, there is no power output, and when the charging current of the connected external electronic device is less than the preset current for a period of time, the corresponding interface output function will be automatically turned off. Pressing the USB control button 810 again will turn off all USB functions.
