[0035] The terminology used in the present invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention.

[0036] When a user has multiple smart devices, he hopes that the charging devices can be effectively used, that is, by arranging as few charging devices as possible in the same or similar areas to power multiple devices. The smart devices targeted by the present invention can be the same or different devices, and their functions can be the same or different, as long as they can share charging devices; the smart devices can be lawn mowers, sweepers, floor scrubbers, vacuum cleaners, lawn mowers and other types of devices that can share charging devices, wherein the smart devices are self-moving devices and / or non-self-moving devices.

[0037] In order to solve the problem of waste of charging equipment resources and low charging efficiency when multiple devices supply charging equipment in the prior art, the present invention provides a charging control method, which is applied to an intelligent system, such as Figure 2 As shown, the intelligent system at least includes a first intelligent device, a second intelligent device and at least one power supply device; the first intelligent device and the second intelligent device share the at least one power supply device; the power supply device includes at least one charging interface; the first intelligent device, the second intelligent device communicate directly with the at least one power supply device and / or communicate through an access point; Figure 1 As shown, the control method includes:

[0038] In response to a charging reservation request from the first smart device and / or the second smart device, the power supply device determines a charging time period according to the reservation request;

[0039] In response to a charging request from the first smart device and / or the second smart device, the power supply device determines a charging strategy according to the charging request.

[0040] The control method of the present invention includes two stages, one is the charging reservation stage, and the other is the charging stage. In the charging reservation stage, when the power of the smart device is lower than the preset value of the total power, a reservation request is issued to negotiate with the power supply device to confirm the charging time period, thereby reducing the probability and time of queuing. Among them, the preset value of the total power can be selected as a value between 25% and 50%, preferably: 50%, 40%, 30% of the total power of the smart device; the reservation request may include the device information, current power, movable distance, etc. of the smart device. In an optional embodiment, the reservation request may also include the remaining workload. When the power supply device receives the charging reservation request sent by the smart device, it determines the charging time period of the smart device according to the internal reservation status, and according to the reservation status, in a preferred embodiment, the power supply device maintains a reservation request list of smart devices, the list including one or more of the identification of the smart device, the reserved charging time period, the remaining power at the time of reservation, and the movable distance at the time of reservation; the power supply device updates the list according to the new charging reservation request, when the reservation time period corresponding to the newly submitted reservation request conflicts with the charging time period of other smart devices that have already been reserved, the power supply device allows the smart device that has newly submitted the reservation request to jump the queue, that is, charge in advance, updates the reservation request list, and notifies the affected smart devices of the updated reservation time period.

[0041] When the smart device establishes a connection with the power supply device during the scheduled time period and enters the charging stage, the smart device and the power supply device negotiate to determine the charging current and / or charging voltage; if the smart device feeds back its battery pack parameter information, the battery pack parameter information includes a recommended charging current and / or a recommended charging voltage; the power supply device determines whether it can use the recommended charging current and / or the recommended charging voltage for charging based on the battery pack parameter information, and when the power supply device can provide the recommended charging current and / or the recommended charging voltage, it uses the recommended charging current and / or the recommended charging voltage for charging; otherwise, the power supply device uses the actual charging current and / or the actual charging voltage that can be provided for charging, wherein the actual charging current is less than the recommended charging current, and the actual charging voltage is less than the recommended charging voltage.

[0042] In an optional embodiment, the power supply device determines the type of the smart device and the maximum allowed charging current and / or maximum charging voltage according to the identification of the smart device, and determines the optimal charging current and / or charging voltage according to the length of the reserved time period, wherein the optimal charging current is not greater than the maximum allowed charging current, preferably, the optimal charging current is 40%-85% of the maximum allowed charging current, and the charging current can be selected according to the length of the charging time period and the total power; in an optional embodiment, the charging voltage is not greater than the maximum charging voltage, and the optimal charging voltage is 50%-95% of the maximum allowed charging voltage, and the charging voltage can be confirmed according to the length of the charging time period and the total power. In the prior art, if charging is performed according to the maximum charging current of the battery, the charging time is short and the efficiency is high, but the battery life is short. If charging is performed with a small current, the battery life is long, but the charging time is also long; the present invention can take into account both the charging speed and the reduction of the impact on the battery life by confirming the optimal charging current and the optimal charging voltage.

[0043] In a preferred embodiment of the present invention, the charging control method further comprises: the first smart device and / or the second smart device determines whether to issue a charging reservation request according to device status information;

[0044] The device status information is determined according to at least one of the device power level, the remaining task amount, and the distance to the power supply device.

[0045] In a preferred embodiment, the charging control method further includes: the first smart device and / or the second smart device determines whether to send a charging reservation request based on the device status information; wherein the device status information is determined based on the ratio of the device power and the remaining task amount. In a preferred embodiment, when the ratio of the device power to the remaining task amount is determined to be in a preset interval, a charging reservation request is sent, wherein the preset interval is: [0.0625-5]. In a further embodiment, the method further includes: when the power of the smart device is lower than the minimum power threshold, a charging reservation request is directly issued, otherwise, it is determined based on the ratio of the device power and the remaining task amount to prevent abnormal shutdown caused by too low power; preferably, the minimum power threshold can be 5%-10% of the total power, and the specific data value can be set according to actual needs, such as according to the area of ​​the operating area, the larger the area, the larger the value of the minimum power threshold.

[0046] Through the solution of the present invention, the smart device initiates a charging reservation request in advance according to its status, so that the power supply device determines the charging time period according to the received charging reservation request, thereby improving the utilization rate of the power supply device and reducing the probability of smart devices queuing; in addition, during the charging stage, the power supply device will determine the charging parameters, such as current, voltage, etc., according to the reserved charging time period, while taking into account the charging efficiency and reducing the impact on battery life.

[0047] In a preferred embodiment, in order to further improve the utilization rate of the power supply device, the charging control method also includes: when the power supply device is in an idle state, the power supply device determines whether to issue a charging scheduling request based on the device status information, wherein the device status information is determined based on at least one of the device power, the remaining task amount, and the distance to the power supply device. When the charging device is idle, the power supply device can issue a charging scheduling broadcast information, and the smart device that receives the scheduling broadcast information feeds back to the power supply device at least one or a combination of multiple information including power, remaining task amount, distance to the power supply device, etc. The power supply device selects a suitable smart device for charging based on the device information, such as requiring the device with the least power or the most remaining tasks, or the device with the closest distance or the smallest ratio of device power to remaining task amount to supplement charging. This improves the utilization rate of the power supply device.

[0048] In a preferred embodiment of the present invention, the charging control method further includes: the power supply device sends a delayed charging reminder message to the first smart device and / or the second smart device. The delayed charging reminder message may be actively sent by the power supply device, or it may be fed back when receiving a charging request from the smart device. In a further embodiment, when the power supply device detects that the power supply device is in a state that is not suitable for providing charging services, it sends a delayed charging reminder message. During the operation of the power supply device, the power supply device may be in a state of heavy load, long working hours, heating, temporary occupation, etc., which may make it impossible to charge normally. At this time, the delayed charging reminder message is sent corresponding to the state trigger of the power supply device. In a further embodiment, the control method also includes: in response to the delayed charging reminder information, the smart device adjusts or does not adjust the working mode; when the smart device receives the delayed charging reminder information, according to the delayed charging reminder information, the smart device determines whether to adjust the working mode according to the delay time and power information, such as determining whether to adjust to a low power consumption mode; when the delay time is short and does not affect the current operation and the power required to return to the power supply device, the working mode is not adjusted and the work continues; when the delay time is long or the remaining power is small, continuing the current operation will affect the possibility of being unable to return to the power supply device for charging, and the smart device is adjusted to a low power consumption state, a sleep state, or directly feedback to the power supply device to queue and wait for charging.

[0049] In a preferred embodiment of the present invention, the charging control method further includes a charging reminder step, specifically including: when the power supply device does not receive a charging request from the smart device within the scheduled time period or within an interval time period before the scheduled time period, the power supply device confirms the charging reminder method and reminder information according to the device type, such as when the smart device is a self-moving device, the power supply device sends a charging reminder message to inform the self-moving device of the scheduled time period, and after the smart device receives the charging reminder message, the smart device feeds back a confirmation message; if the power supply device does not receive the confirmation message, the power supply device continues to send the charging reminder message until the confirmation message is received; in a further embodiment, when the confirmation message is still not received after more than 3 or 5 reminders, the corresponding user terminal is determined according to the smart device, so as to send the charging abnormality information to the user terminal. When the smart device is not a self-moving device, the power supply device determines the corresponding user terminal according to the smart device, and sends the charging reminder message to the user terminal, so that the user terminal reminds the user in the form of sound, light and / or vibration.

[0050] In the solution provided by the present invention, multiple smart devices can share the power supply device. The smart device makes a charging reservation according to the actual device status, and negotiates with the power supply device to determine the charging time period, ensuring that the smart device is recharged when the power supply device resources are available, reducing the probability of charging queues; when the smart device returns to the power supply device to prepare for charging, the power supply device determines the charging strategy according to the charging request of the smart device, ensuring the safe execution of each charging process. Through the solution of the present invention, users do not need to use a power supply device for each smart device, which greatly reduces procurement and installation costs and improves the user's space utilization. At the same time, the solution of the present invention realizes the orderly advancement of the charging process and improves the user experience. Furthermore, the present invention can perform operations such as charging scheduling and delayed charging of smart devices according to the status of the power supply device, effectively improving the utilization rate of the power supply device, reducing the abnormalities caused by the continuous operation of the power supply device, and effectively improving the user experience.

Figure 3 As shown, two smart lawn mowers share a charging pile. The user activates the two smart lawn mowers on the mobile phone APP, and then associates the two smart lawn mowers to share data. The user selects a smart lawn mower to create a map. After the creation is successful, the map information is synchronized to the cloud, and the other smart lawn mower can obtain the map information and save it in the machine. After the user selects the map in the APP and starts mowing, one of the smart lawn mowers A starts mowing, and the other smart lawn mower B charges at the charging pile. When the smart lawn mower A is in a low-power state, the breakpoint is recorded and uploaded to the cloud, and the charging pile is returned. At this time, the smart lawn mower B obtains the breakpoint from the cloud and obtains the latest map information, and goes out to continue mowing. When the smart lawn mower B is in a low-power state, the breakpoint is also recorded and uploaded to the cloud. The smart lawn mower A obtains the breakpoint and updates the map, and goes out to mow, and the cycle is repeated until the lawn is fully covered and cut. Through the scheme of the present invention, not only can multiple devices share power supply equipment, but also can work together, thereby improving the time utilization of smart lawn mowers and providing users with large lawns with more reasonable and efficient cutting solutions.
