Description

[0002] With the development of robot technology, smart mobile devices (such as lawn mowers and floor sweeping machines) have gradually been applied and popularized. After a user finishes using a smart mobile device, the user usually places the smart mobile device on a charging pile for charging.
[0003] In the existing design of a charging pile, during the off-pile process of a smart mobile device and a charging pile, due to physical contact, the loop between the electrical contact piece of the smart mobile device and the charging end (or power supply end) of the charging pile repeatedly turns on and off, which is prone to cause electric spark discharge. The high temperature generated by this electric spark discharge can accelerate the oxidation of the surface of the electrical contact piece, form an insulating oxide layer, cause the contact resistance to exponentially rise, and eventually cause the problem of being unable to charge.

[0064] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0065] Smart mobile devices can include smart robots, smart home devices, and smart transportation vehicles. Smart robots can include lawnmowers, robot vacuums, and food delivery robots; smart home devices can include smart vacuum cleaners, smart air purifiers, and smart security robots; and smart transportation vehicles can include cars and drones. Charging stations, or charging devices, can charge smart mobile devices.
[0066] In existing charging pile designs, the physical separation process between smart mobile devices and the charging pile's power supply presents a dynamic contact problem. When the smart mobile device leaves the charging pile, the two ends of the power supply remain in a high-voltage charging state because the charging circuit is not completely disconnected. At this time, during the mechanical separation process, the metal contacts between the power supply and the charging interface of the smart mobile device experience localized current overload due to the gradual shrinking of the contact area. Because of the tiny gaps between the metal contacts, the high voltage causes the air in the gaps to break down, forming an ionization channel and triggering a momentary electric spark discharge. This discharge phenomenon not only generates high-frequency electromagnetic interference, affecting the stability of surrounding electronic devices and creating safety hazards, but also the high temperature generated by the electric spark accelerates the oxidation of the metal contact surface, forming an insulating oxide layer. This leads to an exponential increase in contact resistance, ultimately causing charging interruption or even preventing charging altogether, thus affecting the lifespan of both the charging pile and the smart mobile device.
[0067] Before describing the solution, it should be noted that, for ease of understanding, some embodiments including charging control parameters will be shown as examples in this application. It should be understood that the charging control parameters are merely illustrative descriptions provided in this application and do not impose any limitations on the embodiments of this application. In practical applications, the specific values of the charging control parameters in the embodiments can be adjusted according to the actual situation.
[0068] The embodiments of this application are described below with reference to the accompanying drawings.
[0069] Figure 1This is a schematic diagram of a first-order voltage control method provided in an embodiment of this application. This method can be executed by a charging pile, by a module applied in the charging pile (e.g., a processor, controller, chip, or chip system), or by a logic node, logic module, or software capable of implementing all or part of the charging pile's functions. For ease of explanation, the following description uses a charging pile as the executing entity of this method as an example. Figure 1 As shown, the method may include all or part of the following steps:
[0070] Step S110: The charging pile detects that the smart mobile device is on the pile and outputs the first power supply voltage to charge the smart mobile device.
[0071] The charging station can continuously or periodically detect whether a smart mobile device is on the station. The detection period for the charging station can be 6 milliseconds as an example, but can be set according to actual needs.
[0072] After the charging station is powered on, the supply voltage can be in a low-voltage state to reduce power consumption. In the low-voltage state, the charging station's supply voltage can be a secondary supply voltage, such as 5 volts.
[0073] A charging station may include a first power supply terminal and a second power supply terminal. For example, Figure 2 This is a schematic diagram of the equivalent charging circuit under low-voltage conditions provided in an embodiment of this application. Figure 2 As shown, the charging pile detection circuit may include equivalent resistances R1 and R2. For example, the power supply voltage of the charging pile is 5 volts during pile detection. The first power supply terminal J1 is used to input the power supply voltage, and the second power supply terminal J2 is grounded (GND). At this time, the voltage between the first power supply terminal J1 and the second power supply terminal J2 is 5*R2 / (R1+R2) volts (referred to here as the first voltage).
[0074] After the smart mobile device is connected to the charging station (i.e., the electrical contacts of the smart mobile device are connected to the first power supply terminal J1 and the second power supply terminal J2), it is equivalent to adding a branch (the dotted box in the figure). The resistance of the branch is the equivalent resistance of the smart mobile device, denoted as R3. The resistance of the equivalent resistance R2 and the equivalent resistance R3 in parallel is denoted as R. Then the voltage between the first power supply terminal J1 and the second power supply terminal J2 is 5*R / (R1+R) volts (here referred to as the second voltage). If the smart mobile device leaves the charging station, it is equivalent to the branch being disconnected. Therefore, the presence or absence of the smart mobile device can be determined based on the voltage of the first power supply terminal J1. That is, when the power supply voltage of the charging station is the second power supply voltage (i.e., the charging station is in a low-voltage state), if the voltage of the first power supply terminal J1 is detected to be the first voltage, it can be determined that the smart mobile device is on the charging station; if the voltage of the first power supply terminal J1 is detected to be the second voltage, it can be determined that the smart mobile device is off the charging station. Here, the first voltage is less than the second voltage. The departure of the smart mobile device from the charging station can include the smart mobile device actively leaving the charging station, the smart mobile device being turned off, or the user manually dragging the smart mobile device away from the charging station.
[0075] After detecting a smart mobile device at the charging station, the charging station can increase the supply voltage from a low voltage state to a high voltage state, such as the first supply voltage.
[0076] Step S120: The charging pile detects that the power supply current is less than or equal to the third current threshold and determines that the smart mobile device is away from the charging pile.
[0077] Figure 3 This is a schematic diagram of an equivalent charging circuit under high voltage conditions provided in an embodiment of this application. Figure 3 As shown, under high voltage conditions, the charging pile's supply voltage can be a first supply voltage, exemplarily 32 volts. If the smart mobile device is removed from the charging pile, the first power supply terminal J1 and the second power supply terminal J2 are in an open circuit state. At this time, the theoretical current between the first power supply terminal J1 and the second power supply terminal J2 is 0 mA. When the smart mobile device is on the charging pile, it is equivalent to having an equivalent resistor R3 connected in series in the circuit. At this time, the current between the first power supply terminal J1 and the second power supply terminal J2 is much greater than 0 mA. Therefore, when the charging pile's supply voltage is the first supply voltage, the magnitude of the current between the first power supply terminal J1 and the second power supply terminal J2 can be used to determine whether the smart mobile device is on the charging pile or not.
[0078] The charging pile can continuously or periodically detect the magnitude of the power supply current. The current detection cycle can be set according to actual needs, for example, it can be the same as the on-pile detection cycle.
[0079] In theory, after a smart mobile device leaves the charging station, the current supplied between the first power supply terminal J1 and the second power supply terminal J2 should be 0 mA. However, due to errors such as the accuracy of current detection, the value of the supply current (called the third current threshold) will be slightly greater than 0 mA. For example, the third current threshold can be 20 mA. The charging station can determine that the smart mobile device has left the station under high voltage when it detects that the supply current is less than or equal to the third current threshold.
[0080] Step S130: The charging pile reduces the power supply voltage from the first power supply voltage to the second power supply voltage.
[0081] To reduce energy waste caused by smart mobile devices being accidentally dragged away from charging stations or by users taking the devices away while they are charging, charging stations can reduce the power supply voltage to a low voltage state, such as a secondary power supply voltage, after detecting that a smart mobile device has left the station. This can reduce power consumption and improve the safety and reliability of the charging system.
[0082] Step S140: The charging pile undergoes on-site testing.
[0083] After determining that the smart mobile device has left the charging station, the charging station can perform a "on-the-spot detection" to wait for the smart mobile device to return to the station. The "on-the-spot detection" can refer to the content of step S110 above, and will not be repeated here.
[0084] Figure 4 This is a second flowchart illustrating the voltage control method provided in an embodiment of this application. Figure 4 As shown, between step S110 and step S140, the method may further include the following steps:
[0085] Step S210: The smart mobile device detects that the battery level is lower than the target battery level and sends a charging instruction to the charging station.
[0086] Smart mobile devices can detect their own battery level. For example, after connecting to a charging station, if a smart mobile device detects that its battery level is lower than a target level, it can send a charging instruction to the charging station, indicating that the smart mobile device is charging. The target level can be set according to actual needs; for example, it can be the battery's total rated capacity or 80% of the total rated capacity.
[0087] In some embodiments, the charging indication can be a charging message frame sent by the smart mobile device to the charging pile, so as to achieve efficient communication between the smart mobile device and the charging pile.
[0088] In other embodiments, the smart mobile device may notify the charging station that it is charging in other ways.
[0089] For example, a smart mobile device can indicate to a charging station that it is charging by causing the charging station to supply a current greater than a first current threshold. The first current threshold can be, for example, 200 mA.
[0090] Specifically, the smart mobile device can charge its battery through the first charging circuit, so that the battery of the smart mobile device is in a charging state. At the same time, the charging pile can also supply power to the target component in the smart mobile device through the second charging circuit, so that the target component is in a powered state, thereby making the power supply current of the charging pile greater than the first current threshold.
[0091] By employing a first charging circuit to charge the battery and a second charging circuit to power the target component, charging efficiency can be improved, avoiding the situation where the battery needs to supply power to the target component while charging, thereby extending the battery's lifespan. The target component may include, but is not limited to, components related to the communication module and control module.
[0092] Step S220: The charging pile receives the charging instruction from the smart mobile device and maintains the power supply voltage at the first power supply voltage.
[0093] When the charging indication is a charging message frame, the charging station can send an acknowledgment frame of the charging message frame to the smart mobile device after confirming that the charging indication has been received, so as to inform the smart mobile device that the charging indication has been received. In addition, the charging station can maintain the power supply voltage at the first power supply voltage, so as to fast charge the smart mobile device.
[0094] In some embodiments, the charging pile can also determine that it has received a charging instruction from the smart mobile device after detecting that the supply current is greater than the first current threshold, and then continue to output the supply voltage as the first supply voltage to charge the smart mobile device.
[0095] Step S230: The smart mobile device detects that the battery level is greater than or equal to the target battery level and sends a full charge maintenance instruction to the charging pile.
[0096] When a smart mobile device detects that the charging level is greater than or equal to the target level, it can determine that charging is complete. Similar to the charging message frame, the full charge maintenance indicator can also be a maintenance message frame, which indicates that the smart mobile device is in a full charge maintenance state.
[0097] In some embodiments, the smart mobile device can also send a full-charge maintenance indication to the charging station by ensuring that the supply current of the charging station is less than or equal to a first current threshold and greater than a second current threshold. The second current threshold may be less than the first current threshold; for example, the second current threshold may be 100 mA or other values.
[0098] For example, a smart mobile device can stop charging the battery while maintaining power supply to the target component. After the battery stops charging, the power supply current will decrease accordingly, so that the power supply current is less than or equal to a first current threshold and greater than a second current threshold.
[0099] Step S240: The charging pile receives the full charge maintenance indication from the smart mobile device and maintains the power supply voltage at the first power supply voltage.
[0100] Upon receiving a full-charge maintenance indication, the charging station can determine that the smart mobile device is in a full-charge maintenance state and that the smart mobile device has no need to leave the charging station. The charging station can then maintain the supply voltage at a first supply voltage. In some embodiments, the charging station can determine that it has received a full-charge maintenance indication when it detects that the supply current is less than or equal to a first current threshold and greater than a second current threshold.
[0101] The charging station maintains the supply voltage at the initial supply voltage to continue powering the target components in the smart mobile device. This keeps the smart mobile device fully charged and better avoids frequent charging and discharging caused by the battery powering the target components, thereby extending the battery's lifespan.
[0102] Step S250: When the smart mobile device is about to leave the charging pile, it sends a departure instruction to the charging pile.
[0103] The removal of smart mobile devices from the charging pile can include the operation of the smart mobile device being turned off and manually removed by the user, as well as the operation of the smart mobile device actively removing from the charging pile.
[0104] Before performing a disconnection operation, a smart mobile device can send a disconnection instruction to the charging station, indicating that the smart mobile device is about to disconnect. This disconnection instruction can be in the form of a disconnection message frame, quickly informing the charging station that the smart mobile device is about to disconnect.
[0105] In some embodiments, the smart mobile device can also cause the charging pile's power supply current to be less than or equal to a second current threshold and greater than a third current threshold, in order to indicate that the smart mobile device is about to leave the charging pile.
[0106] Specifically, the smart mobile device can control some target components to shut down. At this time, the power supply current will continue to decrease, thus becoming less than or equal to the second current threshold. However, since the smart mobile device has not left the pile, the power supply current is greater than the third current threshold.
[0107] Step S260: The charging pile receives the off-pile instruction from the smart mobile device and reduces the power supply voltage from the first power supply voltage to the second power supply voltage.
[0108] After receiving a disconnection instruction from a smart mobile device, the charging station can reduce the supply voltage to a second supply voltage. For example, the charging station can reduce the supply voltage from a first supply voltage to a second supply voltage after determining that the supply current of the smart mobile device is less than or equal to a second current threshold and greater than a third current threshold.
[0109] Since the second power supply voltage is lower than the first power supply voltage, this will prevent the smart mobile device from being unable to automatically shut down after reaching the target power level due to continuous high-voltage charging by the charging pile, and will also reduce the occurrence of electrical sparks when the smart mobile device leaves the charging pile.
[0110] Step S270: The smart mobile device leaves the charging pile after the power supply voltage of the charging pile drops from the first power supply voltage to the second power supply voltage.
[0111] The smart mobile device can leave the charging station after detecting that the power supply voltage of the charging station has dropped from a first power supply voltage to a target power supply voltage, which can be a second power supply voltage. Alternatively, the smart mobile device can also leave the charging station after sending a departure instruction to the charging station for a target duration. Of course, the smart mobile device can also be controlled to leave the charging station if the power supply voltage remains lower than the first power supply voltage for a preset duration.
[0112] Compared to the situation where a smart mobile device leaves the charging station when the charging station's supply voltage is at the first supply voltage, the above implementation method can reduce the occurrence of electrical spark discharge when the smart mobile device leaves the charging station, thereby improving the reliability of the charging system.
[0113] The automatic removal of smart mobile devices from charging stations after charging is complete can improve the efficiency of task execution and increase user satisfaction. After actively removing themselves from the charging station, smart mobile devices can also automatically activate components related to the task to facilitate better task execution.
[0114] In this embodiment, the smart mobile device adjusts its charging strategy according to its own state, thereby adjusting the power supply current of the charging pile. The charging pile determines the state of the smart mobile device based on the detected charging current and outputs a power supply voltage corresponding to the state of the smart mobile device. Therefore, the entire process does not require data network interaction. This not only eliminates the impact of network latency or disconnection on the reliability of the charging system, but also reduces system complexity by simplifying the data link. This allows the charging system to operate normally even in remote areas, underground parking lots, or other weak or no-network scenarios, thereby comprehensively improving the practicality and environmental adaptability of the charging system.
[0115] In some embodiments, when a charging station is charging a smart mobile device or performing on-site detection, an indicator can be controlled to indicate the charging station's operating status in real time. This allows users to determine the charging station's operating status based on the indicator's information, improving user experience and device safety. The indicator may include, but is not limited to, display indicators, light indicators, and sound indicators.
[0116] The following example illustrates an embodiment of this application.
[0117] Figure 5 This is a schematic diagram of a third type of voltage control method provided in an embodiment of this application. Figure 5 As shown, when the charging pile implements the voltage control method, pile detection parameters can be set. These parameters can include an initial on-pile marker, a full-charge marker, and a low-voltage maintenance marker. For example, after the charging pile is powered on, it can write the initial on-pile marker, write the full-charge marker, and clear the low-voltage maintenance marker, setting the supply voltage to a low-voltage state.
[0118] Then it can be determined whether the smart mobile device is on the dock. If the smart mobile device leaves the dock, the initial docking marker, full charge marker, and low voltage maintenance marker can be kept unchanged, or the operation of writing the initial docking marker, writing the full charge marker, and clearing the low voltage maintenance marker can be re-executed.
[0119] When a smart mobile device is in the charging station, the charging station can determine whether there is an initial in-station marker. If there is, the initial in-station marker is cleared and the first power supply voltage is output to charge the smart mobile device. If there is no initial in-station marker, it can continue to determine whether there is a low-voltage maintenance marker.
[0120] If the low-voltage maintenance marker is not present, the charging station can provide the first power supply voltage to charge the smart mobile device; if the low-voltage maintenance marker is present, the power supply status will be maintained at low voltage.
[0121] The charging pile detection system can periodically monitor the magnitude of the supply current. When the detected supply current exceeds a first current threshold, the supply voltage is maintained at the first supply voltage.
[0122] Once the charging station determines that the supply current is less than or equal to a first current threshold and greater than a second current threshold, it can maintain the first supply voltage and clear the low-voltage maintenance flag. Upon detecting that the current supply current is less than or equal to the second current threshold, and determining that the smart mobile device is about to shut down or leave the charging station, it can write a low-voltage maintenance flag and clear the full-charge flag.
[0123] Next, it can be determined whether a full charge marker exists. Since the full charge marker has already been cleared on branches with a supply current less than or equal to the second current threshold, there is no full charge marker. Therefore, a full charge marker can be written, and the system enters a low-voltage state to prevent smart mobile devices from failing to shut down or sparking when disconnected from the charging station. For branches with a supply current greater than the second current threshold, since a full charge marker exists, it can be further determined whether the supply current is greater than the third current threshold. If so, the supply voltage is maintained at the first supply voltage.
[0124] Once the charging station determines that the current supply current is less than or equal to the third current threshold, it can identify when the smart mobile device is removed from the station, write a full charge mark, and the charging station enters a low-voltage state.
[0125] It should be noted that, in the embodiments of this application, the initial charging marker, the full charge marker, and the low voltage maintenance marker are identification information used by the charging system to assist in logical judgment, and do not directly correspond to the actual physical parameters (such as power supply current, power value, charging status, etc.) during the charging process.
[0126] In the voltage control method provided in this application embodiment, the charging pile can receive a notification that the smart mobile device is about to leave the pile, and reduce the power supply voltage of the charging pile from a first power supply voltage to a second power supply voltage, so that the smart mobile device can leave the pile after the power supply voltage is reduced to the second power supply voltage. That is, this scheme can reduce the power supply voltage of the charging pile when the smart mobile device leaves the pile, thus effectively reducing the electrical spark discharge during the process of the smart mobile device leaving the pile, thereby improving the service life of the charging system.
