Integrating a wireless discharge module into a portable outdoor energy storage system can further enhance the customer experience. As a sub-module of the portable outdoor energy storage system, the wireless discharge module needs to enter a low-power mode when there is no load, thereby conserving battery power and extending battery life.

[0003] However, the low-power mode of current wireless discharge modules generally involves the discharge control chip inside the wireless discharge module controlling the wireless discharge module to enter sleep mode after detecting no load for a period of time. In other words, during this process, it is necessary to ensure that the discharge control chip is in standby mode. The standby power consumption current of the discharge control chip varies from 2 to 10 mA. The mA-level standby current is not conducive to extending the battery life of the energy storage system.

[0014] The power input terminal is electrically connected to the discharge control unit through the switching unit to form the discharge circuit;

[0015] The main control module is electrically connected to the touch unit and the switch unit respectively. It is used to control the corresponding switch unit to turn on after the corresponding touch unit detects a first level signal that lasts for a first set time, so that the power voltage of the power input terminal is transmitted to the discharge control unit. It is also used to control the corresponding switch unit to turn off after the touch unit detects a second level signal that lasts for a second set time, so that the power input terminal is disconnected from the discharge control unit.

[0016] Optionally, the switching unit includes a transistor, which may be a P-type transistor or an N-type transistor.

[0019] Optionally, the discharge control unit further includes a first DC-DC converter, a first end of which is coupled to the power input terminal, a second end of which is electrically connected to the discharge coil, and a control terminal of which is electrically connected to the discharge control chip.

[0020] In the discharge mode, the discharge control chip is used to control the first DC-DC converter to adjust the power supply voltage output from the power input terminal to the first discharge voltage according to the required voltage, and output it to the discharge coil.

[0021] Optionally, the discharge control unit further includes a second DC-DC converter. The first end of the second DC-DC converter is coupled to the power input terminal, and the second end of the second DC-DC converter is electrically connected to the power supply terminal of the discharge control chip.

The main control module is electrically connected to both the touch unit and the discharge circuit. It controls the corresponding discharge circuit to conduct after the corresponding touch unit detects the first-level signal, allowing the corresponding wireless discharge module to enter a discharge mode. It also controls the corresponding discharge circuit to disconnect after the corresponding touch unit detects the second-level signal, allowing the corresponding wireless discharge module to enter a sleep mode. The second-level signal is different from the first-level signal. Thus, the touch unit controls the discharge control circuit to switch between the discharge module and sleep mode. In sleep mode, the power supply to the discharge control unit is disconnected, and no power is consumed. The touch unit consumes less power, significantly reducing the power consumption of the discharge control circuit in sleep mode, saving power for the energy storage device, and extending the battery's lifespan.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be fully described below with reference to the accompanying drawings in the embodiments of this invention, through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort fall within the protection scope of this invention.

[0029] Figure 1 This is a schematic diagram of a discharge control circuit provided in an embodiment of the present invention. See also... Figure 1The discharge control circuit includes a motherboard power module 01, a power input terminal P, a main control module 02, and at least one wireless discharge module 03. The wireless discharge module 03 includes a touch unit 10 and a discharge control unit 20, with the power input terminal P and the discharge control unit 20 forming a discharge circuit. The motherboard power module 01 is electrically connected to the touch unit 10, providing a first power supply voltage to the touch unit 10. The touch unit 10 sends a first-level signal when a load device (which can be a wireless load device) is detected, and sends a second-level signal when no load device is detected. The main control module 02 is electrically connected to both the touch unit 10 and the discharge circuit. It controls the corresponding discharge circuit to conduct after the corresponding touch unit 10 detects the first-level signal, causing the corresponding wireless discharge module 03 to enter a discharge mode. It also controls the corresponding discharge circuit to disconnect after the corresponding touch unit 10 detects the second-level signal, causing the corresponding wireless discharge module 03 to enter a sleep mode. The second-level signal is different from the first-level signal.

[0030] Specifically, such as Figure 1 As shown, the discharge control circuit includes a motherboard power module 01, a main control module 02, and multiple wireless discharge modules 03. The motherboard power module 01 is electrically connected to the main control module 02, providing a first power voltage to the touch unit 10 and a second power voltage to the main control module 02. The first power voltage can be 5V, and the second power voltage can be 3.3V. For example,... Figure 1 In the illustrated embodiment, the motherboard power module 01 may include a third DC-DC converter. The input of this third DC-DC converter is electrically connected to the power input terminal P (which can be understood as the power output port of the battery module), and its output is electrically connected to the touch unit 10. The third DC-DC converter converts the power voltage of the power input terminal P or the power voltage of the battery module into a first power voltage (e.g., 5V) and outputs it to the touch unit 10. Furthermore, the discharge control circuit may include a fourth DC-DC converter. The input of the fourth DC-DC converter is electrically connected to the output of the motherboard power module 01, and its output is electrically connected to the main control module 02. The fourth DC-DC converter converts the first power voltage (5V) output by the motherboard power module 01 into a second power voltage (3.3V) and outputs it to the main control module 02. The main control module 02 is the control center of the discharge control circuit, playing a role in monitoring, control, communication, and protection. In both the discharge mode and sleep mode of the wireless discharge module 03, the main control module 02 needs to be provided with the first power voltage to ensure its normal operation. The discharge control circuit also includes at least one wireless discharge module 03. Figure 1This invention uses only three wireless discharge modules 03 as an example for illustration, but the specific number of wireless discharge modules 03 is not limited, and those skilled in the art can set it according to their needs. The wireless discharge module 03 can replace traditional discharge wires and interfaces to achieve power transmission wirelessly. Currently, it is necessary for the wireless discharge module 03 to enter a low-power mode when there is no load, thereby saving battery power and extending the lifespan of the energy storage system. However, in the prior art, the low-power mode of the wireless discharge module generally involves the discharge control chip inside the wireless discharge module controlling the wireless discharge module to enter sleep mode after detecting no load for a period of time. That is, during this process, it is necessary to ensure that the discharge control chip is in standby mode. The standby power consumption current of the discharge control chip ranges from 2 to 10 mA, and a standby current in the mA range is not conducive to extending the battery life of the energy storage system.

[0031] Therefore, in this embodiment of the invention, the touch unit 10 in the wireless discharge module 03 is used to switch between discharge mode and sleep mode, replacing the existing method of switching standby state through a discharge control chip. The touch unit 10 has lower power consumption, which can save power in the energy storage system and extend battery life. Specifically, the wireless discharge module 03 includes a touch unit 10 and a discharge control unit 20. In this embodiment of the invention, the motherboard power module 01 provides the touch unit 10 with a first power supply voltage. It can be understood that in the prior art, the touch unit 10 is provided with a working voltage by the discharge control unit. Therefore, to enable the touch unit 10 to work, the discharge control unit needs to be always powered, resulting in higher power consumption. Here, by providing the touch unit 10 with a first power supply voltage through the motherboard power module 01, it can be ensured that the touch unit 10 can work normally even when the discharge control unit is not powered. The touch unit 10 is electrically connected to the main control module 02. Under operating voltage, when the touch unit 10 senses a load device, it sends a first-level signal to the main control module 02; when it does not sense a load device, it sends a second-level signal to the main control module 02. The first-level signal and the second-level signal are different. In one embodiment, the first-level signal can be a high-level signal, and the second-level signal can be a low-level signal. Furthermore, the first-level signal can also be a low-level signal, and the second-level signal can also be a high-level signal. This invention does not limit these possibilities, and those skilled in the art can configure them as needed.

[0032] Furthermore, the power input terminal P and the discharge control unit 20 form a discharge circuit. When the discharge circuit is on, the power voltage provided by the power input terminal P can be transmitted to the discharge control unit 20; when the discharge circuit is off, the power voltage provided by the power input terminal P cannot be transmitted to the discharge control unit 20. The main control module 02 is electrically connected to multiple touch units 10 and multiple discharge circuits respectively. After the corresponding touch unit 10 detects the first level signal for a first set time, it determines that the corresponding wireless discharge module 03 is in contact with the load device and needs to discharge the load device. Then, it controls the corresponding discharge circuit to be on so that the corresponding wireless discharge module 03 enters the discharge mode. In the discharge mode, the power voltage provided by the power input terminal P can be transmitted to the discharge control unit 20 so that the discharge control unit 20 can charge the load device. After the corresponding touch unit 10 detects the second level signal for a second set time, the main control module 10 determines that the corresponding wireless discharge module 03 is separated from the load device. Then, it controls the corresponding discharge circuit to be off so that the corresponding wireless discharge module 03 enters the sleep mode. In the sleep mode, the power voltage provided by the power input terminal P cannot be transmitted to the discharge control unit 20, and the discharge control unit 20 does not work due to lack of power supply. Thus, the discharge control circuit can be switched between discharge mode and sleep mode by the touch unit 10. In sleep mode, the power supply to the discharge control unit 20 is disconnected and no power is consumed, while the power consumed by the touch unit 10 is small, which greatly reduces the power consumption of the discharge control circuit in sleep mode, saves the power of the energy storage device, and extends the battery life.

[0033] It is understood that the first set time and the second set time can be the same or different, and the embodiments of the present invention do not impose any restrictions on this. Those skilled in the art can set them as needed. By setting the first set time and the second set time, the accidental touch of the touch unit 10 or the failure to determine charging and discharging is avoided, thereby improving the accuracy of charging and discharging determination.

[0034] In summary, the discharge control circuit in this embodiment of the invention includes a motherboard power module, a main control module, and at least one wireless discharge module. The wireless discharge module includes a touch unit and a discharge control unit, with the power input terminal and the discharge control unit forming a discharge circuit. The motherboard power module is electrically connected to the touch unit, providing a first power supply voltage to the touch unit. The touch unit sends a first-level signal when a load device is detected and a second-level signal when no load device is detected. The main control module is electrically connected to both the touch unit and the discharge circuit. It controls the corresponding discharge circuit to conduct after the corresponding touch unit detects the first-level signal, enabling the corresponding wireless discharge module to enter a discharge mode. It also controls the corresponding discharge circuit to disconnect after the corresponding touch unit detects the second-level signal, enabling the corresponding wireless discharge module to enter a sleep mode. The second-level signal is different from the first-level signal. Thus, the touch unit controls the discharge control circuit to switch between discharge and sleep modes. In sleep mode, the power supply to the discharge control unit is disconnected, and no power is consumed. The touch unit consumes less power, significantly reducing the power consumption of the discharge control circuit in sleep mode, saving power for the energy storage device, and extending the battery's lifespan.

[0035] Optionally, based on the above, Figure 2 This is a schematic diagram of another discharge control circuit provided in an embodiment of the present invention. See also... Figure 2 The discharge control unit 20 includes a discharge control chip 210 and a discharge coil 220. In discharge mode, the power input terminal P supplies power to the discharge control chip 210 and transmits the discharge voltage to the discharge coil 220. The discharge control chip 210 is used to adjust the magnitude of the discharge voltage finally transmitted to the discharge coil 220 according to the required voltage.

[0036] For example, in discharge mode, the power supply voltage at the power input terminal P is transmitted to the discharge control unit 20. The discharge control unit 20 includes a discharge control chip 210 and a discharge coil 220. The discharge control chip 210 controls the magnitude of the discharge voltage of the discharge coil 220. For example, when the touch unit 10 senses a load device, the required voltage of the corresponding load device can be obtained through the discharge control chip 210. When the power input terminal P provides power voltage to the discharge control chip 210, the discharge control chip 210 adjusts the final discharge voltage output to the discharge coil 220. For example, if the power input terminal P outputs a power voltage of 24V and the load device requires a voltage of 12V, the discharge control chip 210 can adjust the power input terminal P's power voltage from 24V to 12V and output it to the discharge coil 220, thereby ensuring that the discharge coil 220 outputs a 12V discharge voltage to charge the corresponding load device. In this way, in discharge mode, adjusting the final discharge voltage output to the discharge coil 220 according to the load device's required voltage can further save the energy of the energy storage device, while ensuring the charging safety of the load device and improving reliability.

[0037] It should be noted that the discharge control unit 20 also includes a handshake communication function. That is, in discharge mode, the discharge control unit 20 is also used to send authorization information to the load device, and when the load device returns feedback information corresponding to the authorization information, it controls the discharge coil 220 to discharge the load device. In this way, the verification of the authorization information and feedback information ensures that the wireless load device being discharged is compatible, avoiding charging incompatible devices with incorrect power, which could lead to slow charging, damage to the load device's battery, or overheating and overload of the wireless discharge module 03, thus improving the safety of wireless charging.

[0038] Optionally, based on the above embodiments, see also... Figure 1 and Figure 2 In sleep mode, the power input terminal P is disconnected from the discharge control unit 20, the discharge control unit 20 is not working, and the operating current of the touch unit 10 under the first power supply voltage is in the μA range. Specifically, in this embodiment of the invention, since the discharge mode and sleep mode of the wireless discharge module 03 are switched by the touch unit 10, in sleep mode, the power input terminal P is disconnected from the discharge control unit 20, the discharge control unit 20 is not working, and the touch unit 10 is working. The operating current of the touch unit 10 under the first power supply voltage is in the μA range. Compared with the prior art where the discharge control chip is in standby mode (the standby power consumption current of the discharge control chip is 2~10mA), this greatly reduces the power consumption of the discharge control circuit in sleep mode and further extends the battery life.

[0039] Optionally, based on the above embodiments, Figure 3 This is a schematic diagram of another discharge control circuit provided in an embodiment of the present invention. See also... Figure 3 The wireless discharge module 03 also includes a switching unit 30. The power input terminal is electrically connected to the discharge control unit 20 through the switching unit 30 to form a discharge circuit. The main control module 02 is electrically connected to the touch unit 10 and the switching unit 30 respectively. It is used to control the corresponding switching unit 30 to turn on after the corresponding touch unit 10 detects a first level signal for a first set time, so that the power supply voltage of the power input terminal P is transmitted to the discharge control unit 20. It is also used to control the corresponding switching unit 30 to turn off after the touch unit 10 detects a second level signal for a second set time, so that the power input terminal P is disconnected from the discharge control unit 20.

[0040] For example, such as Figure 3 In the illustrated embodiment, a switch unit 30 is further provided between the power input terminal P and the discharge control unit 20, and the main control module 02 is electrically connected to the control terminal of the switch unit 30. Furthermore, after the corresponding touch unit 10 detects a first-level signal for a first set time, the main control module 02 determines that the corresponding wireless discharge module 03 is in contact with the wireless load device, and then controls the corresponding switch unit 30 to turn on, so that the power voltage output from the power input terminal P can reach the discharge control unit 20 through the switch unit 30 and enter the discharge module. In addition, after the corresponding touch unit 10 detects a second-level signal for a second set time, the main control module 02 determines that the corresponding wireless discharge module 03 is separated from the load device and controls the switch unit 30 to turn off, so that the power voltage output from the power input terminal P cannot reach the discharge control unit 20 through the switch unit 30, and enters a sleep mode. Thus, controlling the corresponding discharge circuit to turn on or off through the switch unit 30 ensures a simple control method for the discharge circuit.

[0041] It should be noted that the switching unit 30 includes a transistor 310, which can be a P-type transistor or an N-type transistor. Specifically, when transistor 310 is a P-type transistor, the main control module 02 sends a low-level signal to the gate of transistor 310 when it detects a first-level signal, causing transistor 310 to conduct, thereby turning on the discharge circuit. When a second-level signal is detected, a high-level signal is sent to the gate of transistor 310, causing transistor 310 to turn off, thereby turning off the discharge circuit. Furthermore, when transistor 310 is an N-type transistor, the main control module 02 sends a high-level signal to the gate of transistor 310 when it detects a first-level signal, causing transistor 310 to conduct, thereby turning on the discharge circuit. When a second-level signal is detected, a low-level signal is sent to the gate of transistor 310, causing transistor 310 to turn off, thereby turning off the discharge circuit.

[0042] Optional, see below Figure 3 The switching unit 30 also includes a transistor 320. The first terminal of the transistor 320 is electrically connected to the output terminal of the main control module 02, the second terminal of the transistor 320 is electrically connected to the ground terminal GND, the third terminal of the transistor 320 is electrically connected to the gate of the transistor 310, the source of the transistor 310 is electrically connected to the power input terminal P, and the drain of the transistor 310 is electrically connected to the discharge control unit 20. Specifically, this embodiment of the invention enhances the driving capability by placing a transistor 320 at the gate of the transistor 310, enabling rapid charging and discharging of the gate of the transistor 310, thereby significantly reducing the switching losses of the transistor 310 and improving the switching speed.

[0043] Optionally, based on the above embodiments, see also... Figure 2 The discharge control unit 20 also includes a first DC-DC converter 230. A first terminal of the first DC-DC converter 230 is coupled to a power input terminal P, a second terminal of the first DC-DC converter 230 is electrically connected to a discharge coil 220, and a control terminal of the first DC-DC converter 230 is electrically connected to a discharge control chip 210. In discharge mode, the discharge control chip 210 controls the first DC-DC converter 230 to adjust the power supply voltage output from the power input terminal P to a first discharge voltage, and outputs it to the discharge coil 220, according to the required voltage.

[0044] For example, such as Figure 2 In the illustrated embodiment, the discharge control unit 20 further includes a first DC-DC converter 230, which is disposed between the power input terminal P and the discharge coil 220, and is used to adjust the magnitude of the power supply voltage output from the power input terminal P. The discharge control chip 210 is electrically connected to the control terminal of the first DC-DC converter 230, and is used to adjust the conversion voltage of the first DC-DC converter 230 according to the required voltage of the load device. For example, when the required voltage of the wireless load device is 12V and the power supply voltage at the power input terminal P is 24V, the discharge control chip 210 sets the conversion voltage of the first DC-DC converter 230 to 12V according to the required voltage (12V) of the load device, so that the first DC-DC converter 230 converts the 24V power supply voltage output from the power input terminal P into a 12V first discharge voltage, and outputs the first discharge voltage to the discharge coil 220. Thus, by setting the first DC-DC converter 230, the method of adjusting the power supply voltage by the discharge control chip 210 is kept simple.

[0045] Optional, see below Figure 2The discharge control unit 20 also includes a second DC-DC converter 240. The first end of the second DC-DC converter 240 is coupled to the power input terminal P, and the second end of the second DC-DC converter 240 is electrically connected to the power supply terminal of the discharge control chip 210. The second DC-DC converter 240 is used to adjust the power supply voltage output from the power input terminal P to the second power supply voltage and output it to the power supply terminal of the discharge control chip 210.

[0046] Specifically, since the power input terminal P outputs a relatively large voltage, directly supplying it to the discharge control chip 210 would damage it. Therefore, this embodiment of the invention also provides a second DC-DC converter 240 at the power supply terminal of the discharge control chip 210. The input terminal of the second DC-DC converter 240 is coupled to the power input terminal P, and the output terminal is electrically connected to the power supply terminal of the discharge control chip 210. The conversion voltage of the second DC-DC converter 240 is fixed, and it can adjust the power output voltage from the power input terminal P to a second power supply voltage. The second power supply voltage can be lower than the first power supply voltage. Preferably, the second power supply voltage can be 3.3V, thereby ensuring that the discharge control chip 210 operates under normal voltage and improving the reliability of the discharge control circuit.

[0047] Based on the same inventive concept, this invention also provides an energy storage device, which includes a battery module and a discharge control circuit as described in the above embodiment. The battery module provides a power input voltage to the power input terminal of the discharge control circuit. Therefore, this energy storage device has the same beneficial effects as the discharge control circuit described above, and will not be described in detail here.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
