It should be understood that the capacity formula in this embodiment is only exemplary, and in other embodiments, the operation of the formula needs to take other original parameters into consideration, which is not specifically explained herein.

In some embodiments, when the processor 20 controls the energy storage power supply 200 to be connected to the charging circuit 51, that is, when the processor 20 controls the charging circuit 51 to be turned on, the processor 20 can control the utility power grid 300 to charge the energy storage power supply 200 with electric energy for a preset period of time through the charging circuit 51, and at this time, the processor 20 can also obtain the electric quantity charged in the preset period of time, so that the processor 20 can obtain the charging efficiency according to the preset period of time and the charged electric quantity. For example, if the preset time period is t1 and the amount of electricity charged in the preset time period is 50mah, the charging efficiency is 50mah/t1. In addition, the processor 20 can also obtain the time period required for the energy storage power supply 200 to be charged to the full charge (the state of charge is 100%) according to the capacity, the current power amount and the charging efficiency of the energy storage power supply 200. For example, if the capacity of the energy storage power supply 200 is 100mah, the current power is 40mah, and the power (charging efficiency) charged in a unit time is 10mah/min, the time required for the energy storage power supply 200 to be charged to full power is:

Accordingly, in the case where the processor 20 controls the energy storage power supply 200 to be connected to the discharge circuit 53, that is, in the case where the processor 20 controls the discharge circuit 53 to be turned on, the processor 20 can control the energy storage power supply 200 to discharge the electric energy to the load 400 for a predetermined period of time through the discharge circuit 53, at this time, the processor 20 can also obtain the amount of electric energy discharged for the predetermined period of time, and thus, the processor 20 can obtain the discharge efficiency according to the predetermined period of time and the amount of electric energy discharged. For example, if the predetermined time period is t2 and the amount of electricity released in the predetermined time period is 50mah, the discharge efficiency is 50mah/t2. In addition, the processor 20 can also be based on stored energyThe capacity, current charge, and discharge efficiency of the source 200 obtain the time remaining for the energy storage power source 200 to discharge to empty (state of charge of 0). For example, if the capacity of the energy storage power supply 200 is 100mah, the current electric quantity is 40mah, and the electric quantity released in unit time (discharge efficiency) is 10mah/min, the remaining time period from the discharge of the energy storage power supply 200 to the power empty is:

it will be appreciated that in some embodiments, the preset time period and the predetermined time period may be known data, which may be an empirical value obtained before the power distribution apparatus 100 is shipped, or a set value input by a person using the power distribution apparatus 100 after the power distribution apparatus 100 is shipped.

Referring to fig. 2, 3 and 7, in some embodiments, 03: acquiring parameter information according to charge and discharge parameters generated by the energy storage power supply 200 in the power-empty state by the power distribution device 100 accessing the power distribution circuit 50, including:

031: in the case where the power distribution apparatus 100 is not in the parameter setting mode, controlling the energy storage power supply 200 to access the power distribution circuit 50 to perform a discharging operation; and

033: in the case where the energy storage power source 200 is discharged to the power-empty state, the power distribution apparatus 100 is controlled to enter the learning mode.

Referring to fig. 2 and 3, the processor 20 is further configured to perform the power distribution methods of 031 and 033, that is, the processor 20 is further configured to: in the case where the power distribution apparatus 100 is not in the parameter setting mode, controlling the energy storage power supply 200 to access the power distribution circuit 50 to perform a discharging operation; and controlling the power distribution apparatus 100 to enter the learning mode in the case where the energy storage power source 200 is discharged to the power-empty state.

Specifically, in some embodiments, in the case where the power distribution apparatus 100 is not in the parameter setting mode, the power storage apparatus 200 is controlled to access the power distribution circuit 50 to perform the discharging operation, and in the case where the power storage apparatus 200 is discharged to the power empty state, the power distribution apparatus 100 is controlled to enter the learning mode, thereby being capable of preventing the processor 20 from being unable to directly acquire the parameter information of the power storage apparatus 200, so that the power distribution apparatus 100 is unable to control the operating state of the power storage apparatus 200, that is, the power distribution apparatus 100 is also able to control the operating state of the power storage apparatus 200 with which communication is not established and with which the original parameters are unable to be obtained, thereby further improving the applicability of the power distribution apparatus 100. The charge and discharge parameters in this embodiment are the same as those in the above embodiment, and will not be described here.

The "empty state" and the "full state" may be two states of the electric quantity in the energy storage power source 200. The "power empty state" refers to a state in which the amount of power in the stored power source 200 has been completely exhausted without any remaining power. The "full-charge state" refers to a state in which the energy in the energy storage power supply 200 has been completely filled, and the maximum capacity of the energy storage power supply 200 is reached.

In some embodiments, the manner in which the processor 20 confirms that the power distribution device 100 is not in the parameter setting mode may be: whether the power distribution apparatus 100 is in the parameter setting mode is confirmed according to the input of the user. For example, the user clicks cancel or skip the parameter setting mode through the control panel 40, and the processor 20 confirms that the power distribution apparatus 100 is not in the parameter setting mode. In other embodiments, the manner in which the processor 20 confirms that the power distribution apparatus 100 is not in the parameter setting mode may be: whether the power distribution device 100 is in the parameter setting mode is confirmed according to a period of time during which the power distribution device 100 is in the parameter setting mode. For example, after the parameter setting mode for the preset time is displayed on the control panel 40, the processor 20 does not acquire the original parameters input by the user yet, and the processor 20 confirms that the power distribution apparatus 100 is not in the parameter setting mode. The preset time may be known data, which may be an empirical value obtained before the power distribution apparatus 100 leaves the factory, or a set value input when the power distribution apparatus 100 is manually used after the power distribution apparatus 100 leaves the factory.

It will be appreciated that in other embodiments, the power distribution method may be: in the case where the power distribution apparatus 100 is not in the parameter setting mode, the power distribution apparatus 100 is controlled to enter the learning mode, and in the case where the power distribution apparatus 100 is in the learning mode, the energy storage power supply 200 is controlled to access the power distribution circuit 50 to perform a discharging operation to discharge the energy storage power supply 200 to an empty state. In this case, the processor 20 is configured to: in the case where the power distribution apparatus 100 is not in the parameter setting mode, the power distribution apparatus 100 is controlled to enter the learning mode, and in the case where the power distribution apparatus 100 is in the learning mode, the energy storage power supply 200 is controlled to access the power distribution circuit 50 to perform a discharging operation to discharge the energy storage power supply 200 to an empty state.

Referring to fig. 3 and 8, in some embodiments, 03: acquiring parameter information according to charge and discharge parameters generated by an energy storage power supply in an empty electric state through a power distribution device connected to a power distribution circuit, wherein the parameter information comprises:

035: the energy storage power supply 200 is controlled to be connected to the charging circuit 51 so as to charge the energy storage power supply 200 to a full-charge state through the charging circuit 51, and the charging time length and the charged electric quantity are recorded so as to acquire the capacity of the energy storage power supply 200;

037: acquiring charging efficiency according to the charging duration and the charged electric quantity;

038: controlling the energy storage power supply 200 to be connected to the discharge circuit 53 so as to discharge the energy storage power supply 200 to an empty state through the discharge circuit 53, and recording the discharge duration and the released electric quantity;

039: and obtaining the discharge efficiency according to the discharge time length and the released electric quantity.

Referring to fig. 3, the processor 20 is further configured to perform the power distribution methods 035, 037, 038 and 039, i.e., the processor 20 is further configured to: the energy storage power supply 200 is controlled to be connected to the charging circuit 51 so as to charge the energy storage power supply 200 to a full-charge state through the charging circuit 51, and the charging time length and the charged electric quantity are recorded so as to acquire the capacity of the energy storage power supply 200; acquiring charging efficiency according to the charging duration and the charged electric quantity; controlling the energy storage power supply 200 to be connected to the discharge circuit 53 so as to discharge the energy storage power supply 200 to an empty state through the discharge circuit 53, and recording the discharge duration and the released electric quantity; and obtaining the discharge efficiency according to the discharge time length and the released electric quantity.

Specifically, in some embodiments, in a case where the processor 20 controls the energy storage power supply 200 to be connected to the charging circuit 51, that is, in a case where the processor 20 controls the charging circuit 51 to be turned on, the processor 20 can control the utility power grid 300 to charge the energy storage power supply 200 to a full state through the charging circuit 51, at this time, the processor 20 can also obtain a charging time period required for the energy storage power supply 200 to be charged to the full state and a charged electric quantity (that is, a charging capacity of the energy storage power supply 200), and thus, the processor 20 can obtain a charging efficiency according to the charging time period and the charged electric quantity. For example, if the charging time period required for charging the energy storage power supply 200 to the full power state is 10min and the charged electric quantity is 100mah, the charging efficiency is 10mah/min (i.e. 100mah/10 min).

Accordingly, in the case that the processor 20 controls the energy storage power supply 200 to be connected to the discharge circuit 53, that is, in the case that the processor 20 controls the discharge circuit 53 to be turned on, the processor 20 can control the energy storage power supply 200 to supply power to the load 400 through the discharge circuit 53 so as to discharge the energy storage power supply 200 to the power-empty state, at this time, the processor 20 can also obtain the discharge duration required by the energy storage power supply 200 to discharge to the power-empty state and the amount of electricity to be discharged (that is, the discharge capacity of the energy storage power supply 200), and thus, the processor 20 can obtain the discharge efficiency according to the discharge duration and the amount of electricity to be discharged. For example, if the discharge time period required for discharging the energy storage power supply 200 to the power-free state is 10min and the amount of electric power discharged is 100mah, the discharge efficiency is 10mah/min (i.e., 100mah/10 min).

Referring to fig. 3, in some embodiments, the power distribution method further comprises:

in the case that the power distribution device 100 is in a communication state with the energy storage power supply 200, the communication module 30 of the power distribution device 100 acquires parameter information from the energy storage power supply 200; and

The operating state of the energy storage power supply 200 is controlled according to the parameter information.

Referring to fig. 3 and 9, the processor 20 is further configured to perform the above-mentioned power distribution method, that is, the processor 20 is further configured to: in the case that the power distribution device 100 is in a communication state with the energy storage power supply 200, the communication module 30 of the power distribution device 100 acquires parameter information from the energy storage power supply 200; and controlling the operating state of the energy storage power supply 200 according to the parameter information.

In some embodiments, the communication status (as shown in fig. 9, there is "communication") may be: the power distribution device 100 and the energy storage power supply 200 are connected in a communication manner and can realize a data transmission state. It should be noted that, in some embodiments, the power distribution device 100 and the portable unit can be in a communication state when the power distribution device 100 is electrically connected to the same brand and/or the same model of the energy storage power source 200.

Further, in some embodiments, the power distribution apparatus 100 may further include a communication module 30, where the communication module 30 is electrically connected to the processor 20 and is configured to communicate with the stored energy power source 200. Specifically, in the case where communication is established between the communication module 30 and the energy storage power supply 200, the processor 20 acquires that the power distribution apparatus 100 and the energy storage power supply 200 are in a communication state, in which case the processor 20 can acquire parameter information of the energy storage power supply 200 through the communication module 30. It should be noted that, in some embodiments, the communication module 30 may establish communication with the energy storage power source 200 through a wired connection or a wireless connection. Wherein, the wired connection is that the communication module 30 is electrically connected with the energy storage power supply 200 by using a tangible medium such as a metal wire or an optical fiber to establish communication; the wireless connection is that the communication module 30 is connected with the energy storage power supply 200 by Wi-Fi, 4G or bluetooth to establish communication.

Still further, in some embodiments, the energy storage power supply 200 may be provided with a communication unit (not shown), which may be a module in the energy storage power supply 200 responsible for communicating with other devices, and the communication unit may be capable of receiving signals transmitted from other devices to the energy storage power supply 200, and transmitting signals from the energy storage power supply 200 to other devices with which communication is established. The communication unit may establish communication with the communication module 30 through a wired connection or a wireless connection, so as to implement a communication connection between the energy storage power source 200 and the power distribution device 100. Under the condition that the communication unit establishes communication with the communication module 30, the communication unit can send the parameter information of the energy storage power supply 200 to the communication module 30, so that the processor 20 can acquire the parameter information of the energy storage power supply 200 through the communication module 30, and the communication unit can also acquire the control information of the energy storage power supply 200 sent by the processor 20 from the communication module 30, so that the power distribution equipment 100 can apply the energy storage power supply 200 to the power distribution system 1000, thereby increasing the application range of the energy storage power supply 200 and improving the applicability of the energy storage power supply 200.

Referring to fig. 10, in some embodiments, in a case where the power distribution apparatus 100 starts to operate, for example, in a case where the power distribution apparatus 100 is electrically connected to the energy storage power source 200, the processor 20 can acquire a communication state between the power distribution apparatus 100 and the energy storage power source 200, and in a case where the power distribution apparatus 100 is in a communication state with the energy storage power source 200, the processor 20 can acquire parameter information of the energy storage power source 200 through the communication module 30; and in the case that the power distribution device 100 and the energy storage power supply 200 are in a non-communication state, the processor 20 needs to continuously confirm whether the power distribution device 100 is in the parameter setting mode to obtain the parameter information of the energy storage power supply 200. The specific step of the processor 20 in the present embodiment for confirming whether the power distribution device 100 is in the parameter setting mode is the same as the specific step of the processor 20 in the above embodiment for confirming whether the power distribution device 100 is in the parameter setting mode, and will not be described herein.

In other embodiments, the processor 20 can directly confirm whether the power distribution device 100 is in the parameter setting mode to obtain the parameter information of the energy storage power source 200 in the case where the power distribution device 100 starts to operate, for example, in the case where the power distribution device 100 is electrically connected to the energy storage power source 200. The specific step of the processor 20 in the present embodiment for confirming whether the power distribution device 100 is in the parameter setting mode is the same as the specific step of the processor 20 in the above embodiment for confirming whether the power distribution device 100 is in the parameter setting mode, and will not be described herein.

Referring to fig. 3, in some embodiments, the power distribution circuit 50 may further include a first switch 60 and a second switch 70. The first switch 60 is disposed on the charging circuit 51, and is used for controlling on/off of the charging circuit 51. The second switch 70 is disposed on the discharge circuit 53 and is used for controlling the on-off of the discharge circuit 53.

Specifically, in some embodiments, the number relationship between the first switches 60 and the charging circuits 51 is one-to-one, that is, one first switch 60 corresponds to one charging circuit 51; the number relationship between the second switches 70 and the discharge circuits 53 is one-to-one, that is, one second switch 70 corresponds to one discharge circuit 53.

When the processor 20 controls the first switch 60 to be in the first state, the charging circuit 51 is in an off state, and at this time, no electrical connection exists between the charging circuit 51 and the energy storage power supply 200, and the electrical energy of the utility power grid 300 cannot be transmitted to the energy storage power supply 200 through the charging circuit 51 to realize the charging operation; when the processor 20 controls the first switch 60 to be in the second state, the charging circuit 51 is in the conducting state, and at this time, the charging circuit 51 is electrically connected to the energy storage power source 200, and the electric energy of the utility power grid 300 can be transmitted to the energy storage power source 200 through the charging circuit 51 to realize the charging operation. Accordingly, when the processor 20 controls the second switch 70 to be in the first state, the discharging circuit 53 is in the off state, and at this time, no electrical connection exists between the discharging circuit 53 and the energy storage power supply 200, and the electrical energy of the energy storage power supply 200 cannot be transmitted to the load 400 to realize the discharging operation; when the processor 20 controls the second state, the discharging circuit 53 is in a conductive state, and at this time, the discharging circuit 53 is electrically connected to the energy storage power source 200, and the electric energy of the energy storage power source 200 can be transferred to the load 400 to implement a discharging operation.

In some embodiments, the power distribution circuit 50 may further include a power supply circuit 55, one end of the power supply circuit 55 is electrically connected to the utility power grid 300, the other end is electrically connected to the load 400, the charging circuit 51 shares a part of a circuit with the power supply circuit 55, and the second switch 70 is further used to control on/off of the power supply circuit 55.

Specifically, in some embodiments, when the processor 20 controls the second switch 70 to be in the third state, the power supply circuit 55 is in a conductive state, at which time, the electric energy of the utility grid 300 can be transmitted to the load 400 to supply power to the load 400; when the processor 20 controls the first switch 60 to be in the first state, the power supply circuit 55 is in an off state, and at this time, the electric energy of the utility grid 300 cannot be transmitted to the load 400 to supply power to the load 400.

It will be appreciated that in other embodiments, the power distribution circuit 50 may further include a third switch (not shown) disposed on the power supply circuit 55 and configured to control the on/off of the power supply circuit 55. At this time, the second switch 70 cannot control the on-off of the power supply circuit 55, in other words, the power supply circuit 55 and the charging circuit 51 are two independent lines, and there is no common portion therebetween. When the processor 20 controls the third switch to be in the first state, the power supply circuit 55 is in an off state, and at this time, no electrical connection exists between the utility power grid 300 and the load 400, and electrical energy of the utility power grid 300 cannot be transmitted to the load 400 through the power supply circuit 55 to supply power to the load 400; when the processor 20 controls the third switch to be in the second state, the power supply circuit 55 is in a conducting state, and at this time, the utility grid 300 is electrically connected to the load 400, and the electric energy of the utility grid 300 can be transmitted to the load 400 through the power supply circuit 55 to supply power to the load 400.

In some embodiments, the metering detection circuit 80 can also be disposed in the power supply circuit 55 and electrically connected to the processor 20, and the metering detection circuit 80 is configured to detect the amount of power released by the utility grid 300. The power released by the utility power grid 300 includes the power transmitted by the utility power grid 300 to the load 400 through the power supply circuit 55, and the power transmitted by the utility power grid 300 to the energy storage power supply 200 through the charging circuit 51.

Referring to fig. 3, in some embodiments, controlling the operation state of the energy storage power supply 200 according to the parameter information includes:

in the case that the operating voltage standard of the utility power grid 300 connected to the power distribution apparatus 100 is different from the operating voltage standard of the energy storage power supply 200, the power distribution apparatus 100 issues a prompt message and makes the energy storage power supply 200 not access to the utility power grid 300.

The processor 20 is also configured to perform the above-described power distribution method, i.e., the processor 20 is also configured to: in the case that the operating voltage standard of the utility power grid 300 connected to the power distribution apparatus 100 is different from the operating voltage standard of the energy storage power supply 200, the power distribution apparatus 100 issues a prompt message and makes the energy storage power supply 200 not access to the utility power grid 300.

If the working voltage standards of the utility power grid 300 and the energy storage power supply 200 electrically connected to the same power distribution device 100 are different, the utility power grid 300 and the energy storage power supply 200 cannot be stably electrically connected, and in the case that the utility power grid 300 is electrically connected to the energy storage power supply 200, the power distribution circuit 50 and/or the energy storage power supply 200 are easily damaged, so that the safety risk of the power distribution device 100 and/or the energy storage power supply 200 is high, and the service life of the power distribution device 100 and/or the energy storage power supply 200 is shortened. Therefore, in the present application, in the case that the operating voltage standard of the utility power grid 300 connected to the power distribution device 100 is different from the operating voltage standard of the energy storage power source 200, the power distribution device 100 can send out a prompt message (for example, the processor 20 controls the indicator lamp 45 to emit light) to prompt the user to turn off the power distribution device 100, and/or the processor 20 can control the energy storage power source 200 not to be connected to the utility power grid 300, that is, control to disconnect the electrical connection between the power distribution circuit 50 and the energy storage power source 200 (the first switch 60 and the second switch 70 are both in the first state of being disconnected), thereby preventing the power distribution circuit 50 and/or the energy storage power source 200 from being damaged, reducing the safety risk of the power distribution device 100 and/or the energy storage power source 200, and prolonging the service life of the power distribution device 100 and/or the energy storage power source 200.

More specifically, in some embodiments, in the case where the energy storage power supply 200 is used as a backup power supply for household electricity, the processor 20 can obtain the current power (remaining power) of the energy storage power supply 200 in real time, and in the case where the power of the energy storage power supply 200 does not reach the preset power, the charging circuit 51 is controlled to be turned on, so that the power of the utility power grid 300 can be transmitted to the energy storage power supply 200 through the charging circuit 51 to reach the preset power. It should be noted that, in some embodiments, the preset power may be the power of the energy storage power source 200 in the full power state. The preset power may be known data, or may be an empirical value obtained before the power distribution device 100 leaves the factory, or may be a set value input when the power distribution device 100 is manually used after the power distribution device 100 leaves the factory.

the energy storage power supply 200 is controlled to be connected to the power distribution circuit 50 according to at least one of the capacity, the charging efficiency and the discharging efficiency of the energy storage power supply 200 to perform the discharging operation.
