Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The existing power supply system is shown in fig. 1, and different devices can supply power to each other. However, the power supply system shown in fig. 1 has a problem of low efficiency when power is supplied to each other between different devices. If the device 1 supplies power to the device 2, the device 1 needs to supply power to the device 2 as a whole, including the battery unit and the load, and in particular, needs to charge the battery unit of the device 2. This reduces the standby time of the entire system composed of the device 1 and the device 2.

In the conventional power supply system II, as shown in fig. 2, the electric quantity between different battery units in the same device is balanced, and the battery units supply power for the same load together. However, the second power supply system is only used for balancing the electric quantity among different battery units in the same device, and the electric quantity redistribution among different devices is not involved.

In view of the foregoing problems in the prior art, embodiments of the present application provide a power supply method for a multi-device system 10. As shown in fig. 3, the multi-device system 10 includes at least two devices (only device a101 and device B102 are shown in fig. 3 for convenience of illustration), each including a battery module 112 and at least two load modules 111 corresponding to the battery module 112. In this embodiment, the device a101 and the device B102 each include a first load module 111 (load module 1111 in fig. 3), a second load module 111 (load module 1112 in fig. 3), and an nth load module 111 (load module 111n in fig. 3).

The power supply method of the multi-device system 10 provided in this embodiment includes: determining the standby time of each battery module 112 and the priority of each load module 111, wherein the priority is the priority of each load module 111 participating in dynamic grouping power supply, and the dynamic grouping power supply is that the load modules 111 are powered by the battery modules 112 in devices other than the device in which the load modules 111 are positioned; the load modules 111 to be involved in the dynamic group power supply are subjected to the dynamic group power supply based on the standby time of each battery module 112 and the priority of each load module 111.

According to the power supply method of the multi-device system 10, dynamic grouping division of the load modules 111 inside the multi-device system 10 can be achieved, and the load modules 111 and the battery modules 112 among different devices can be combined into one power supply load unit, so that standby time of a system (namely the multi-device system 10) formed by a plurality of devices is maximized. The power supply method can solve the problems that a plurality of load modules 111 of the existing equipment cannot be divided into groups, the load modules 111 among different equipment modules cannot be dynamically combined, and the load modules 111 among different equipment and the battery modules 112 cannot be dynamically combined.

The present application is described in further detail below with reference to the drawings and specific examples of the specification.

Example 1

A method of powering a multi-device system 10, as shown in fig. 4, comprising:

step 1: the standby time of each battery module 112 and the priority of each load module 111 are determined, wherein the priority is the priority of each load module 111 participating in dynamic grouping power supply, and the dynamic grouping power supply supplies power to the load modules 111 by the battery modules 112 in devices other than the device where the load modules 111 are located.

Step 2: the load modules 111 to be involved in the dynamic group power supply are subjected to the dynamic group power supply based on the standby time of each battery module 112 and the priority of each load module 111.

In an exemplary embodiment, one device in the multi-device system 10 includes a first load module 111, load modules 1112, …, and an nth load module 111, for a total of n load modules 111. The priorities of the n load modules 111 in the device are predetermined, for example, the priorities of the power supplied from the first load module 111 to the n load module 111 by the battery modules 112 in the devices other than the device in which the n load modules are located are sequentially increased.

In some embodiments, determining the standby time of the battery module 112 by each device in step 1 may be implemented by the following method:

the battery capacity of the battery module 112 is determined in milliamp-hours (mAh). The static power consumption of the device in the standby mode is determined, which refers to the current consumed by the device when no operation is performed. The standby time can be calculated by dividing the battery capacity of the battery module 112 by the static power consumption of the device in the standby mode. The formula is standby time (hours) =battery capacity (mAh)/static power consumption (mA).

In this embodiment, step 2 may specifically include:

step 201: determining a first battery module 112 with the longest standby time among all the battery modules 112, and determining a second battery module 112 with a standby time difference from the first battery module 112 exceeding a preset limit; the standby time difference is the time difference between the standby time and the longest standby time;

step 202: confirming the load modules 111 to participate in dynamic grouping power supply from all the load modules 111 corresponding to the second battery module 112 according to the priority level of the priority level; the load module 111 to be involved in dynamic group power supply performs dynamic group power supply.

As in some embodiments, the multi-device system 10 includes a device a101 and a device B102, the device a101 including a first load module 111, a second load module 111, …, an nth load module 111, and a battery module 112, the device B102 including a first load module 111, a second load module 111, …, an nth load module 111, and a battery module 112.

All load modules 111 and all battery modules 112 form a complete power supply circuit. According to the priority order of the load modules 111, the first load module 111 of the device a101 has the highest priority of being supplied by the battery module 112 in the device a101, and the battery module 112 in the other devices (except the device a101, i.e., the device B102 in this embodiment) has the lowest priority; the nth load module 111 of the device a101 has the lowest priority of being supplied with power by the battery module 112 in the device a101, and the highest priority of being supplied with power by the battery module 112 in the device B102 other than the device a101 where itself is located.

If it is confirmed in step 201 that the standby time is the battery module 112 (the first battery module 112) in the device B102 and the standby time difference between the battery module 112 and the first battery module 112 in the device a101 exceeds the preset limit, i.e. the battery module 112 in the device a101 is the second battery module 112. The standby time of the second battery module 112 is smaller than the standby time of the first battery module 112. Alternatively, the preset clipping may be set to a value equal to or greater than zero. Therefore, when the preset clipping is set to zero and the standby time difference between the second battery module 112 and the first battery module 112 exceeds zero, the battery module 112 in the device B102 preferably performs dynamic group power supply to the nth load module 111 of the device a 101.

In some embodiments, the multi-device system 10 includes a device a101, a device B102, a device C103, a device D (not shown in the figure), and the like, when it is determined that the standby time is the longest in step 201, the battery module 112 in the device B102 (which is the first battery module 112), and the standby time differences between the battery module 112 in the device a101 and the battery module 112 in the device C103 and the battery module 112 in the device B102 exceed the preset limit, that is, the battery module 112 in the device a101 and the battery module 112 in the device C103 are both the second battery module 112. The n-th load module 111 of device a101 and the n-th load module 111 of device C103 are powered dynamically in groups by the battery module 112 in device B102.

Example two

On the basis of the first embodiment, the present embodiment provides a power supply method of the multi-device system 10, and in step 202, the load module 111 to be involved in dynamic group power supply performs dynamic group power supply only if the first preset condition is satisfied.

In this embodiment, the first preset condition is: the sum of the power consumption of all load modules 111 to be engaged in dynamic group power supply and the power consumption of all load modules 111 corresponding to the first battery module 112 does not exceed the power of the first battery module 112.

In this embodiment, by limiting the total power consumption of the sum of the power consumption of the load modules 111 to be involved in dynamic group power supply and the power consumption of all the load modules 111 corresponding to the first battery module 112, the total power consumption does not exceed the power of the first battery module 112, so that the first battery module 112 can be ensured to provide enough energy to meet the requirements of the system, which helps to prevent the battery from overdischarging, and avoid the situation of system breakdown or unstable power supply caused by the excessive power consumption, and in addition, the charging and discharging processes of the battery module 112 can affect the service life thereof. By limiting the overall power consumption, the battery life may be reduced under high power conditions, thereby extending the battery life.

Example III

In this embodiment, based on the second embodiment, step 2 in the power supply method of the multi-device system 10 specifically includes:

each device transmits the standby time of the battery module 112 in itself to all devices except itself in the multi-device system 10; each device determines a first battery module 112 having the longest standby time among all battery modules 112 according to the standby time of the battery modules 112 in itself and the received standby time of the battery modules 112 in all devices except itself, and determines a second battery module 112 having a standby time difference from the first battery module 112 exceeding a preset limit.

As shown in fig. 5, a multi-device system 10 is still illustrated as including a device a101 and a device B102, each having a separate battery module 112. The load module 111 of each device may be powered by the battery module 112 of the device or by the battery modules 112 of other devices. The device a101 and the device B102 may calculate standby times when power is supplied solely by the own battery module 112, and transmit the own standby times to the counterpart device through the communication interface 113. The device with the short standby time initiates a request to the other device, and the other device can supply power to the partial load module 111 (i.e. the determined load module 111 to participate in dynamic packet power supply) with the short standby time through the power interface 114 in response to the request. Finally, the load module 111 in the device having a short standby time will be simultaneously powered by the battery module 112 of the device a101 and the battery module 112 of the device B102, and maximize the standby time of the entire system.

As shown in fig. 5, in the present embodiment, the nth load module 111 of the device a101 is powered by the battery of the device B102, the other load modules 111 of the device a101 are powered by the battery of the device a101, and all the load modules 111 of the device B102 are powered by the battery of the device B102.

It may be appreciated that, in a specific embodiment, in the battery module 112 with short standby time (or a standby time threshold may be set, where the standby time is smaller than the standby time threshold, that is, the standby time is determined to be short), or in the device where the standby time difference between the first battery module 112 and the second battery module 112 exceeds the preset limit, the load module 111 with the highest priority level participating in dynamic grouping power supply may be powered by the battery module 112 with the highest standby time; the load modules 111 with the highest priority level participating in dynamic grouping power supply can be selected according to the priority order, and the battery modules 112 with the highest standby time supply power.

In consideration of the case where the power supply of the multi-device system 10 is stable and the battery is prevented from being excessively discharged, the dynamic group power supply is performed to the load module 111 to be involved in the dynamic group power supply in the case where the first preset condition is satisfied.

In some embodiments, the multi-device system 10 includes a plurality of devices, each of which calculates a standby time when the battery module 112 is powered by itself, and transmits the standby time to all devices except itself through the communication interface 113, each of which can determine a first battery module 112 having the longest standby time among all battery modules 112 according to the standby time of the battery module 112 in itself and the standby time of the battery module 112 in all devices except itself received, and determine a second battery module 112 having a standby time difference from the first battery module 112 exceeding a preset limit. The device where the standby time difference between the device and the first battery module 112 exceeds the preset limit (may include a plurality of battery modules 112) may initiate a request to the device where the first battery module 112 with the longest standby time is located, and the device where the first battery module 112 is located may respond to the request and may supply power to a part of the load modules 111 (i.e. the determined load modules 111 to participate in dynamic group power supply) in the device sending the request through the power interface 114. Finally, the load module 111 in the device that transmits the request simultaneously supplies power from the battery module 112 corresponding to itself and the battery module 112 having the longest standby time, and maximizes the standby time of the entire system.

In particular embodiments, the power interface 114 may be designed based on a switch. As shown in fig. 6, the battery module 112 on each device is connected to the corresponding load module 111 in one device through the power interface 114, and the battery module 112 on each device is also connected to the load modules 111 in other devices through the power interface 114.

The power interface 114 requires additional control lines to transmit control signals of the power interface 114 for controlling the switching of the switches in the power interface 114. If the load module 111 needs to supply power through the battery module 112 corresponding to the load module 111, a switch in the power interface 114 between the connected load module 111 and its corresponding battery module 112 needs to be opened, and a switch between the connected load module 111 and the battery module 112 in other devices needs to be closed.

In the present embodiment, communication is performed between the device a101 and the device B102 through the communication interface 113.

The communication interface 113 may enable data transfer between devices using selected communication protocols and hardware combinations. Such as serial communication interface 113, uses serial communication protocols (e.g., RS232, RS485, UART) to transfer data between devices through a serial port. Or Ethernet communication interface 113, which connects devices through a local area network or the internet using an Ethernet protocol (e.g., TCP/IP), to achieve data transmission between the devices. Or a wireless communication interface 113 that enables communication between devices via wireless signals using wireless technology (e.g., wi-Fi, bluetooth, zigbee). Or bus communication: data transfer and communication between devices is accomplished using a unified bus protocol (e.g., I2C, SPI, CAN, modbus) to connect multiple devices to a bus.

Example IV

In the present embodiment, based on the second embodiment, in the power supply method of the multi-device system 10 provided in the present embodiment, step 2 specifically includes:

each device transmits the standby time of the battery module 112 in itself, the priority of the load module 111, to the battery management unit 115 through the communication interface 113;

the battery management unit 115 determines a first battery module 112 having the longest standby time among all the battery modules 112 according to the standby time of each battery module 112 and the priority of each load module 111, and determines a second battery module 112 having a standby time difference from the first battery module 112 exceeding a preset limit.

The battery management unit 115 confirms the load modules 111 to be involved in dynamic grouping power supply corresponding to the second battery module 112 from all the load modules 111 corresponding to the second battery module 112 according to the priorities of the load modules 111; the first battery module 112 is controlled to perform dynamic group power supply to the load module 111 to be involved in dynamic group power supply.

The present embodiment is more suitable for application scenarios when more than two devices are included in the multi-device system 10, and the battery management unit 115 manages all the battery modules 112 and the power supply circuits of each battery module 112.

As shown in fig. 7, in this embodiment, the device a101, the device B102, the device C103, and the device D (not shown in the figure) together form a multi-device system 10, where each device includes a first load module 111 (i.e., the load module 1111 in fig. 7), a second load module 111 (i.e., the load module 1112 in fig. 7), and a … nth load module 111 (i.e., the load module 111n in fig. 7). Each device comprises a respective battery module 112, and the load modules 111 of all devices and all battery modules 112 form a complete power supply loop. The priority of the power supplied by the battery module 112 of the device A101 is highest by the first load module 111 of the device A101, and the priority of the power supplied by the battery modules 112 of other devices is lowest; the nth load module 111 of the device a101 is the lowest in power supply priority by the battery module 112 in the device a101 and the highest in power supply priority by the battery modules 112 in the other devices. When the power supply capability of the battery module 112 in the device a101 is insufficient, the other battery modules 112 preferentially supply power to the nth load module 111 of the device a 101.

In this embodiment, each device calculates the standby time for the battery module 112 to supply power to all the load modules 111 of the device according to the capacity of the device, and transmits the standby time to the battery management unit 115 through the communication interface 113. After the battery management unit 115 calculates that the battery module 112 with the maximum standby time belongs to the device B102, it is counted that the battery module 112 with the standby time difference from the battery module 112 of the device B102 exceeding the preset limit belongs to the device a101 and the device C103.

In this embodiment, in the case where the first preset condition is satisfied, the dynamic group power supply is performed on the load modules 111 to be involved in the dynamic group power supply, that is, when the sum of the power consumption Pb of all the load modules 111 corresponding to the device B102, the power consumption Pan of the n-th load module 111 of the device a101, and the power consumption Pcn of the n-th load module 111 of the device C103 is lower than the power Pb of the battery module 112 in the device B102, the expression Pb > =pb+pan+pcn is given, and then the battery module 112 in the device B102 supplies power to all the load modules 111 corresponding to the battery module 112 in the device B102, the n-th load module 111 of the device a101, and the n-th load module 111 of the device C103, and the battery module 112 in the device a101 supplies power to the load modules 111 other than the n-th load module 111 in the device a101 and the battery module 112 in the device C103. In the embodiment shown in fig. 7, the nth load module 111 of device a101 and the nth load module 111 of device C103 are powered by the battery module 112 of device B102, the other load modules 111 of device a101 are powered by the battery module 112 of device a101, the other load modules 111 of device C103 are powered by the battery module 112 of device C103, and all load modules 111 of device B102 are powered by the battery module 112 of device B102.

When the sum of the power consumption Pb of all the corresponding load modules 111 in the device B102 and the power consumption Pan of the nth load module 111 of the device a101 and the power consumption Pcn of the nth load module 111 of the device C103 is higher than the power consumption Pb of the battery module 112 in the device B102, but the common power consumption Pb of the power consumption Pb and the power consumption Pan is lower than the power consumption Pb, and the common power consumption Pb of the device and the power consumption Pcn of the nth load module 111 of the device C103 is lower than the power consumption Pb of the battery module 112 in the device B102, the expression is:

P _B <＝P _b +P _an +P _cn ；

P _B >＝P _b +P _an ；

P _B >＝P _b +P _cn ；

the battery module 112 in the device B102 supplies power to the nth load module 111 in the device having a larger standby time difference between the battery modules 112 in the device a101 and the device C103 and the battery module 112 in the device B102. The power supply loop of other batteries and devices remains unchanged.

When the sum of the power consumption Pb of all the corresponding load modules 111 in the device B102 and the power consumption Pan of the n-th load module 111 of the device a101 and the power consumption Pcn of the n-th load module 111 of the device C103 is higher than the power consumption Pb of the battery module 112 in the device B102, and the common power consumption Pb of the power consumption Pb and the power consumption Pan is higher than the power consumption Pb, the common power consumption Pb of the n-th load module 111 of the device C103 and the power consumption Pb of the battery module 112 in the device B102 is lower than the power consumption Pb of the battery module 112, the expression is:

P _B <＝P _b +P _an +P _cn ；

P _B <＝P _b +P _an ；

P _B >＝P _b +P _cn ；

the battery module 112 in device B102 supplies power to all load modules 111 in device B102 and the nth load module 111 of device C103. The power supply loop of other batteries and devices remains unchanged.

According to the power supply method provided by the embodiment of the application, the load module 111 and the battery module 112 are divided by dynamic grouping, so that the longest battery life of a system formed by a plurality of devices can be obtained in a standby state, and the service time of the system is prolonged; the load modules 111 and the battery modules 112 of different devices can be combined into a power supply load unit, and the dynamic combination mode enables the system to have stronger flexibility, and the load and the power supply of each device can be adjusted and combined according to actual needs.
