For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or an internal connection between two devices, elements, or components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] Please see Figure 1 , which is a schematic diagram of the structure of an electronic device 100 according to an embodiment of the present application, including at least one processor 120 and a memory 130, Figure 1 A processor is taken as an example. The processor 120 and the memory 130 are connected via the bus 110. The memory 130 stores instructions that can be executed by at least one processor 120. The instructions are executed by at least one processor 120 so that at least one processor 120 executes the discharge control method in the following embodiment.

[0032] like Figure 2As shown, it is a scene schematic diagram of a discharge system 200 of an embodiment of the present application, and the discharge system 200 includes: an energy device 210 and an electric device 220, wherein the energy device 210 may be a battery pack, and the electric device 220 may be an electric tool such as a lawn mower or a lawn mower, and the energy device 210 may provide electric energy for the electric device 220, and the energy device 210 is by default the only available power source for the electric device 220. When the energy device 210 is not connected to the electric device 220, it is in a dormant state. When the energy device 210 is plugged into the electric device 220, the electric device 220 is powered on and started, and at this time, the energy device 210 is activated due to the discharge current.

[0033] like Figure 3 As shown, it is a flow chart of a discharge control method according to an embodiment of the present application. The method can be applied to Figure 2 In the discharge system 200 scenario shown in FIG. Figure 1 The electronic device 100 or Figure 2 The energy device 210 in the embodiment is used to monitor the discharge process and stop the discharge in time when an abnormal situation occurs. The method includes the following steps:

[0034] Step 310: After receiving the activation signal from the power-consuming device 220, continuously obtain the state information of the energy device 210 during the discharge process.

[0035] In the above steps, the energy device 210 is in a dormant state without discharging when there is no power-consuming device 220 connected. When a power-consuming device 220 is connected to the energy device 210 and started, the energy device 210 can receive an activation signal from the power-consuming device 220, and the energy device 210 is therefore activated and begins to continuously obtain status information of the energy device 210 during the discharge process.

[0036] In one embodiment, the activation signal may be a discharge current. When the power-consuming device 220 is connected to the energy device 210 and started, the energy device 210 is activated due to the discharge current.

[0037] Step 320: Determine whether the energy device 210 is discharging normally according to the status information.

[0038] In the above steps, the status information may include battery cell voltage, battery cell temperature, discharge current, etc. Based on the status information, it is determined whether the energy device 210 is discharged normally. If the energy device 210 is discharged normally, step 330 is executed; if the energy device 210 is not discharged normally, step 340 is executed.

[0039] Step 330 : Send a discharge signal to the powered device 220 .

[0040] In the above steps, the energy device 210 continuously sends a discharge signal to the power-consuming device 220 during normal discharge. As long as the status information of the energy device 210 is normal, the discharge signal will not be interrupted. Once the discharge signal is interrupted, the power-consuming device 220 will report an error and stop using electricity.

[0041] In one embodiment, after the power-consuming device 220 is started, if it does not receive the discharge signal sent by the energy device 210 within a preset time period, it will report an error and enter the standby state. The preset time period can be determined according to the actual time required for signal transmission.

[0042] Step 340 : disconnect the discharge circuit between the power-consuming device 220 and the energy device 210 .

[0043] In the above steps, a signal may be sent to the power-consuming device 220 to control the power-consuming device 220 to shut down, or a signal may be generated to disconnect the discharge circuit inside the energy device 210. In one embodiment, the discharge circuit inside the energy device 210 may be disconnected while controlling the power-consuming device 220 to shut down, thereby ensuring that the discharge circuits of the power-consuming device 220 and the energy device 210 are disconnected in time to avoid equipment damage, explosion, fire and other safety issues.

[0044] In one embodiment, a signal may be preferentially sent to the power-consuming device 220 to control the power-consuming device 220 to shut down. When the shutdown mechanism of the power-consuming device 220 fails, a signal is generated to disconnect the discharge circuit inside the energy device 210. In one embodiment, a signal may be preferentially generated to disconnect the discharge circuit inside the energy device 210. When the disconnection mechanism of the discharge circuit inside the energy device 210 fails, a signal is sent to the power-consuming device 220 to control the power-consuming device 220 to shut down.

[0045] like Figure 4 As shown, it is a flow chart of a discharge control method according to an embodiment of the present application. The method can be applied to Figure 2 In the discharge system 200 scenario shown in FIG. Figure 1 The electronic device 100 or Figure 2 The energy device 210 in the embodiment is used to monitor the discharge process and stop the discharge in time when an abnormal situation occurs. The method includes the following steps:

[0046] Step 410: After receiving the activation signal from the power-consuming device 220, continuously obtain the state information of the energy device 210 during the discharge process. For details, refer to the description of step 310 in the above embodiment.

[0047] Step 420: Determine whether the cell voltage of the energy device 210 is lower than a preset voltage threshold.

[0048] In the above steps, the status information includes the battery cell voltage, and it is determined whether the battery cell voltage of the energy device 210 is lower than the preset voltage threshold. If the battery cell voltage of the energy device 210 is not lower than the preset voltage threshold, it is determined that the energy device 210 is discharged normally, and step 430 is executed. If the battery cell voltage of the energy device 210 is lower than the preset voltage threshold, it is determined that the energy device 210 is not discharged normally, and step 440 is executed.

[0049] Step 430: Send a discharge signal to the power-consuming device 220. For details, refer to the description of step 330 in the above embodiment.

[0050] Step 440 : Send a first power-off signal to the powered device 220 .

[0051] In the above steps, the energy device 210 sends a first power-off signal to the power-consuming device 220 , and the first power-off signal is used to control the power-consuming device 220 to shut down, thereby stopping power consumption.

[0052] Step 450: Determine whether the discharge circuit between the power-consuming device 220 and the energy device 210 is disconnected.

[0053] In the above steps, due to signal transmission problems or a fault in the electrical device 220 itself, the shutdown mechanism of the electrical device 220 may fail and the discharge circuit between the electrical device 220 and the energy device 210 may not be disconnected. Therefore, it is determined whether the discharge circuit between the electrical device 220 and the energy device 210 is disconnected. If the discharge circuit between the electrical device 220 and the energy device 210 is not disconnected, it indicates that the shutdown mechanism of the electrical device 220 fails, and step 460 is executed. If the discharge circuit between the electrical device 220 and the energy device 210 is disconnected, it indicates that the shutdown mechanism of the electrical device 220 has taken effect and the energy device 210 has stopped discharging.

[0054] Step 460: Generate a second power-off signal.

[0055] In the above steps, a second power-off signal is generated, and the second power-off signal is used to disconnect the discharge circuit inside the energy device 210, thereby stopping the discharge and preventing the battery cell voltage of the energy device 210 from being too low. In one embodiment, the second power-off signal can disconnect the discharge circuit by controlling the MOS tube inside the energy device 210.

[0056] like Figure 5 As shown, it is a flow chart of a discharge control method according to an embodiment of the present application. The method can be applied to Figure 2 In the discharge system 200 scenario shown in FIG. Figure 1 The electronic device 100 or Figure 2The energy device 210 in the embodiment is used to monitor the discharge process and stop the discharge in time when an abnormal situation occurs. The method includes the following steps:

[0057] Step 510: After receiving the activation signal from the power-consuming device 220, continuously obtain the state information of the energy device 210 during the discharge process. For details, refer to the description of step 310 in the above embodiment.

[0058] Step 520: Determine whether the battery cell temperature of the energy device 210 is within a preset temperature range.

[0059] In the above steps, the status information includes the battery cell temperature, and determines whether the battery cell temperature of the energy device 210 is within the preset temperature range. If the battery cell temperature of the energy device 210 is within the preset temperature range, it is determined that the energy device 210 is discharged normally, and step 530 is executed. If the battery cell temperature of the energy device 210 is not within the preset temperature range, it is determined that the energy device 210 is not discharged normally, and step 540 is executed.

[0060] Step 530: Send a discharge signal to the power-consuming device 220. For details, refer to the description of step 330 in the above embodiment.

[0061] Step 540: Send a first power-off signal to the powered device 220. For details, refer to the description of step 440 in the above embodiment.

[0062] Step 550: Determine whether the discharge circuit between the power-consuming device 220 and the energy device 210 is disconnected.

[0063] In the above steps, if the discharge circuit between the electrical device 220 and the energy device 210 is not disconnected, it means that the shutdown mechanism of the electrical device 220 is invalid, and step 560 is executed. If the discharge circuit between the electrical device 220 and the energy device 210 is disconnected, it means that the shutdown mechanism of the electrical device 220 has taken effect and the energy device 210 has stopped discharging.

[0064] Step 560: Generate a second power-off signal. For details, refer to the description of step 460 in the above embodiment.

[0065] like Figure 6 As shown, it is a flow chart of a discharge control method according to an embodiment of the present application. The method can be applied to Figure 2 In the discharge system 200 scenario shown in FIG. Figure 1 The electronic device 100 or Figure 2 The energy device 210 in the embodiment is used to monitor the discharge process and stop the discharge in time when an abnormal situation occurs. The method includes the following steps:

[0066] Step 610: After receiving the activation signal from the power-consuming device 220, continuously obtain the state information of the energy device 210 during the discharge process. For details, refer to the description of step 310 in the above embodiment.

[0067] Step 620: Determine whether the discharge current of the energy device 210 is higher than a preset current threshold.

[0068] In the above steps, the status information includes the discharge current, and it is determined whether the discharge current of the energy device 210 is higher than the preset current threshold. If the discharge current of the energy device 210 is not higher than the preset current threshold, it is determined that the energy device 210 is discharged normally, and step 630 is executed. If the discharge current of the energy device 210 is higher than the preset current threshold, it is determined that the energy device 210 is not discharged normally, and step 640 is executed.

[0069] Step 630: Send a discharge signal to the power-consuming device 220. For details, refer to the description of step 330 in the above embodiment.

[0070] Step 640: Generate a second power-off signal.

[0071] In the above steps, a second power-off signal is generated, and the second power-off signal is used to disconnect the discharge circuit inside the energy device 210. Since overcurrent during the discharge process of the energy device 210 is a very unsafe situation, when the discharge current of the energy device 210 is higher than the preset current threshold, the discharge circuit between the power-consuming device 220 and the energy device 210 must be disconnected at the fastest speed. In one embodiment, the second power-off signal can disconnect the discharge circuit by controlling the MOS tube inside the energy device 210, thereby ensuring that there is no overcurrent.

[0072] Step 650: Determine whether the discharge circuit between the power-consuming device 220 and the energy device 210 is disconnected.

[0073] In the above steps, due to the failure of the energy device 210 itself, for example, failure of the MOS tube, etc., the disconnection mechanism of the energy device 210 may fail, and the discharge circuit between the power-consuming device 220 and the energy device 210 is not disconnected. Therefore, it is determined whether the discharge circuit between the power-consuming device 220 and the energy device 210 is disconnected. If the discharge circuit between the power-consuming device 220 and the energy device 210 is not disconnected, it means that the disconnection mechanism of the energy device 210 fails, and step 660 is executed. If the discharge circuit between the power-consuming device 220 and the energy device 210 is disconnected, it means that the disconnection mechanism of the energy device 210 has taken effect, and the energy device 210 has stopped discharging.

[0074] Step 660 : Send a first power-off signal to the powered device 220 .

[0075] In the above steps, the first power-off signal is used to control the power-consuming device 220 to shut down.
