[0147] In an embodiment of the present application, the detection voltage of the sixth terminal 16 of the control module 10 is obtained by the main controller G2, and when the detection voltage is greater than a first preset value, it is determined that the connection between the control module 10 and the battery module 20 is abnormal, so that the staff can be informed and handled in time.

[0148] Optionally, in some embodiments, the control module 10 and n battery modules 20 are stacked; the reconfigurable power supply also includes a protection module 40; the protection module 40 is connected to the nth battery module 20, and the protection module 40 is used to protect the battery module 20.

[0149] In some embodiments, interfaces are provided at one end of the control module 10 , one end of the protection module 40 , and both ends of each battery module 20 to facilitate the connection between the control module 10 , the protection module 40 , and each battery module 20 .

[0150] In the embodiment of the present application, since the control module 10 and n battery modules 20 are stacked structures, the protection module 40 is connected to the n-th battery module 20, so that the plug or slot at the bottom of the n-th battery module 20 can be covered and protected to avoid safety hazards of the plug or slot at the bottom of the n-th battery module 20 under conditions such as moisture, water accumulation, and accidental touch, thereby protecting each battery module 20.

[0152] In the embodiment of the present application, when the first end of the third resistor R3 in the protection module 40 is connected to the sixth end 16 of the control module 10 , it is determined that the connection of the protection module 40 is normal.

[0153] Optionally, in some embodiments, the main controller G2 is further used to determine that the connection between the protection module 40 and the nth battery module 20 is abnormal when the detection voltage is greater than a second preset value; wherein the second preset value is less than the first preset value.

[0154] In the embodiment of the present application, the main controller G2 determines that the connection between the protection module 40 and the nth battery module 20 is abnormal when the detection voltage is greater than the second preset value, so that the staff can be informed and handled in time.

[0155] Reference Figure 9 In some embodiments, the reconfigurable power supply includes a control module 10, two battery modules 20, and a protection module 40. When the control module 10 and each battery module 20 are normally connected, and the protection module 40 and the second battery module 20 are normally connected, the second end of the second resistor R2 is electrically connected to the first end of each first resistor R1 and the first end of the third resistor R3. The second resistor R2 is connected in series with each first resistor R1 and the third resistor R3. Each first resistor R1 and the third resistor R3 are connected in parallel. The first preset value is a voltage value of the divided voltage of the two first resistors R1 in parallel, and the second preset value is a voltage value of the divided voltage of the two first resistors R1 and the third resistor R3 in parallel. The detection voltage of the sixth end 16 of the control module 10 is the voltage of the second end V1 of the second resistor R2.

[0156] If the connection between the protection module 40 and the second battery module 20 is abnormal, the second resistor R2 is connected in series with the two first resistors R1 in parallel. The voltage divided by the two first resistors R1 in parallel increases, making the detection voltage greater than the second preset value, thereby determining that the connection between the protection module 40 and the second battery module 20 is abnormal.

[0157] For the case where the connection between the control module 10 and the battery module 20 is abnormal, for example, the connection between the control module 10 and the second battery module 20 is abnormal, that is, the connection between the control module 10 and the first battery module 20 is normal, but the connection between the first battery module 20 and the second battery module 20 is abnormal. At this time, the second resistor R2 is connected in series with the first resistor R1 in the first battery module 20, that is, the voltage divided by the first resistor R1 in the first battery module 20 increases, so that the detection voltage is greater than the first preset value, thereby determining that the connection between the control module 10 and the battery module 20 is abnormal.

[0158] In some embodiments, the resistance value of each first resistor R1 and the resistance value of the third resistor R3 are N ohms, and the resistance value of the second resistor R2 is 1 ohm;

[0159] In the case where the connection between the protection module 40 and the n-th battery module 20 is abnormal, the total resistance of the n parallel-connected first resistors R1 is N / n ohms, and the main controller G2 determines that the connection between the protection module 40 and the n-th battery module 20 is abnormal when the detection voltage is greater than the second preset value;

[0160] When the protection module 40 is normally connected to the n-th battery module 20, the total resistance of the n first resistors R1 and the third resistors R3 connected in parallel is N / (N+n), and the main controller G2 determines that the protection module 40 is normally connected to the n-th battery module 20 when the detection voltage is less than the second preset value;

[0161] It should be noted that the resistance value of each first resistor R1, the resistance value of the third resistor R3 and the resistance value of the second resistor R2 need to be selected to satisfy the total resistance value of the n parallel first resistors R1, which is different from the total resistance value of the n parallel first resistors R1 and third resistors R3.

[0162] In an embodiment of the present application, by detecting the connection between the control module 10 and the battery module 20 and the protection module 40 and the nth battery module 20, it is possible to avoid the safety hazards of the interface of the control module 10, the interface of the battery module 20, and the interface of the protection module 40 under conditions such as moisture, water accumulation, and accidental touch, which may cause damage to the reconfigurable power supply when the connection between the control module 10 and the battery module 20 is abnormal, the connection between the battery module 20 and the battery module 20 is abnormal, or the connection between the protection module 40 and the nth battery module 20 is abnormal.

[0163] Optionally, in some embodiments, the control module 10 is further used to increase the number of discharged batteries E1 in parallel when the discharge current of the reconfigurable power supply is less than a first current threshold, and to reduce the number of discharged batteries E1 in parallel when the discharge current is greater than a second current threshold, and to maintain the number of discharged batteries E1 in parallel unchanged when the discharge current is greater than or equal to the first current threshold and less than or equal to the second current threshold.

[0164] In some embodiments, the controller G1 in each battery module 20 is controlled by the main controller G2 to increase the number of parallel discharged batteries E1 when the discharge current of the reconfigurable power supply is less than a first current threshold, and to reduce the number of parallel discharged batteries E1 when the discharge current is greater than a second current threshold, and to maintain the number of parallel discharged batteries E1 unchanged when the discharge current is greater than or equal to the first current threshold and less than or equal to the second current threshold.

[0165] In an embodiment of the present application, when the discharge current of the reconfigurable power supply is less than the first current threshold, it indicates that the discharge current is too small, and the control module 10 increases the number of parallel discharged batteries E1 to increase the discharge current; in some embodiments, the number of parallel discharged batteries E1 is increased by switching the parallel isolated or series isolated batteries E1 or the series batteries E1 to parallel batteries E1. The specific implementation process is similar to the above and will not be repeated here; when the discharge current is greater than the second current threshold, it indicates that the discharge current is too large, and the control module 10 reduces the number of parallel discharged batteries E1 to reduce the discharge current. In some embodiments, the number of parallel discharged batteries E1 is reduced by switching the parallel batteries E1 to parallel isolated or series isolated batteries E1 or the series batteries E1. The specific implementation process is similar to the above and will not be repeated here; when the discharge current is greater than or equal to the first current threshold and less than or equal to the second current threshold, it indicates that the discharge current is normal, and the control module 10 maintains the number of parallel discharged batteries E1 unchanged.

[0166] Optionally, in some embodiments, the control module 10 is further used to increase the number of discharged batteries E1 in series when the discharge voltage of the reconfigurable power supply is less than a first voltage threshold, and to reduce the number of discharged batteries E1 in series when the discharge voltage is greater than a second voltage threshold, and to maintain the number of discharged batteries E1 in series unchanged when the discharge voltage is greater than or equal to the first voltage threshold and less than or equal to the second voltage threshold.

[0167] In some embodiments, the controller G1 in each battery module 20 is controlled by the main controller G2 to increase the number of discharged batteries E1 in series when the discharge voltage of the reconfigurable power supply is less than a first voltage threshold, and to reduce the number of discharged batteries E1 in series when the discharge voltage is greater than a second voltage threshold, and to maintain the number of discharged batteries E1 in series unchanged when the discharge voltage is greater than or equal to the first voltage threshold and less than or equal to the second voltage threshold.

[0168] In an embodiment of the present application, when the discharge voltage of the reconfigurable power supply is less than the first voltage threshold, it indicates that the discharge voltage is too small. The control module 10 increases the number of discharged batteries E1 in series to increase the discharge voltage. In some embodiments, the number of discharged batteries E1 in series is increased by switching the series-isolated or parallel-isolated batteries E1 or the parallel-connected batteries E1 to series-connected batteries E1. The specific implementation process is similar to the above and will not be repeated here. When the discharge voltage is greater than the second voltage threshold, it indicates that the discharge voltage is too large. The control module 10 reduces the number of discharged batteries E1 in series to reduce the discharge voltage. In some embodiments, the number of discharged batteries E1 in series is reduced by switching the series-isolated or parallel-isolated batteries E1 to parallel-isolated or series-isolated batteries E1 or parallel-connected batteries E1. The specific implementation process is similar to the above and will not be repeated here. When the discharge voltage is greater than or equal to the first voltage threshold and less than or equal to the second voltage threshold, it indicates that the discharge voltage is normal and the number of discharged batteries E1 in series remains unchanged.

[0169] Optionally, in some embodiments, the control module 10 is further configured to increase the number of discharged batteries E1 in response to an instruction to increase the discharge power of the reconfigurable power supply, and to reduce the number of discharged batteries E1 in response to an instruction to reduce the discharge power of the reconfigurable power supply.

[0170] In some embodiments, the controller G1 in each battery module 20 is controlled by the master controller G2 to increase or decrease the number of discharged batteries E1 .

[0171] In an embodiment of the present application, the control module 10 responds to an instruction to increase the discharge power of the reconfigurable power supply and increases the number of discharged batteries E1 to increase the discharge power. In some embodiments, the number of discharged batteries E1 is increased by switching the series-isolated or parallel-isolated batteries E1 to series-isolated or parallel-isolated batteries E1. The specific implementation process is similar to the above and will not be repeated here. The control module 10 responds to an instruction to reduce the discharge power of the reconfigurable power supply and reduces the number of discharged batteries E1 to reduce the discharge power. In some embodiments, the number of discharged batteries E1 is reduced by switching the series-isolated or parallel-isolated batteries E1 to series-isolated or parallel-isolated batteries E1. The specific implementation process is similar to the above and will not be repeated here.

[0172] Optionally, in some embodiments, the control module 10 is further configured to control the battery E1 to stop charging or discharging when the battery E1 is abnormal.

[0173] In some embodiments, the master controller G2 controls the controller G1 in the battery module 20 where the battery E1 is abnormal, so as to stop charging and discharging the battery E1 when the battery E1 is abnormal.

[0174] In an embodiment of the present application, the control module 10 controls the battery E1 to stop charging and discharging when the battery E1 is abnormal, so as to avoid damage to the reconfigurable power supply. In some embodiments, the abnormal battery E1 is isolated in parallel or in series to stop charging and discharging the abnormal battery E1. The specific implementation process is similar to the above and will not be repeated here.

[0175] In some embodiments, when each switch of the reconfigurable power supply is disconnected, the reconfigurable power supply is in standby mode; when each battery E1 in the reconfigurable power supply is connected in series, the reconfigurable power supply is in series mode; when multiple batteries E1 in the reconfigurable power supply are connected in series and there are batteries E1 isolated in series, the reconfigurable power supply is in series isolation mode; when each battery E1 in the reconfigurable power supply is connected in parallel, the reconfigurable power supply is in parallel mode; when multiple batteries E1 in the reconfigurable power supply are connected in parallel and there are batteries E1 isolated in parallel, the reconfigurable power supply is in parallel isolation mode; when the electrical connection relationship of multiple batteries E1 in the reconfigurable power supply is a combination of series and parallel, the reconfigurable power supply is in series-parallel combination mode; the series isolation mode or the parallel isolation mode can isolate batteries E1 at any position and number in the reconfigurable power supply, and can be adjusted without disassembly. In addition, in the series-parallel combination mode, the batteries E1 can also be isolated in parallel or in series.

[0176] The sensor detection in the embodiments of the present application can realize functions such as voltage and current measurement, high-voltage overcurrent detection, and fault alarm; the housing of the control module 10 protects the top of the reconfigurable power supply. In some embodiments, the control module 10 has an electronic external screen or physical buttons, which can control the mode switching of the reconfigurable power supply and the adjustment of the number of batteries E1 charged and discharged.

[0177] In this embodiment of the present application, when adjusting the number of batteries E1 to be charged or discharged, the reconfigurable power supply's mode switching is restricted to prevent excessive charge and discharge currents from damaging the battery module 20. When the reconfigurable power supply mode is selected, the adjustment of the number of batteries E1 to be charged or discharged is restricted. Different modes of the reconfigurable power supply correspond to different upper limits on the number of batteries E1 to be charged or discharged, which can be achieved by detecting the connection between the control module 10 and the battery module 20.
