[0051] Currently, the charging currents adapted by robots of different models are different. Existing charging piles are designed with different types of charging piles to adapt to robots of different models. Different types of charging piles can output different charging currents. However, each type of charging pile can only charge one model of robot and cannot be compatible with multiple models of robots, reducing the practicality of the charging pile.

[0052] In an exemplary embodiment, such as Figure 1As shown in the figure, the charging pile 200 includes: a first electrode plate 202 and multiple charging interfaces 201 for connecting the adapter 100 and receiving the charging power input by the adapter 100. Among them, the types of the adapters 100 connected by the multiple charging interfaces are different. A charging circuit 300 is connected to the multiple charging interfaces 201 and is used to output the charging power to the device to be charged through the first electrode plate 202 for charging when one of the charging interfaces 201 is connected to the adapter 100.

[0053] Among them, each of the multiple charging interfaces 201 is respectively connected to an adapter 100 of a corresponding type, and the adapter 100 of the corresponding type outputs a charging power adapted to be received by the charging interface 201, that is, each of the multiple charging interfaces 201 receives a corresponding charging power. In addition, each charging interface 201 is connected to an adapter 100 of a different type, and the charging power output by each adapter 100 is also different. The adapters 100 of different types may include adapters with different charging modes, charging parameters, and interface models, etc.

[0054] Among them, the charging mode includes a compatible charging mode and a fixed charging mode. The charging parameters may include charging current, charging voltage, charging power, etc., which are not specifically limited in this application. The compatible charging mode refers to a charging mode in which the charging power can be adjusted after the charging protocol is successfully matched, and the fixed charging mode refers to a charging mode in which charging is performed according to a fixed charging power.

[0055] In this embodiment, when any one of the multiple charging interfaces 201 is connected to a corresponding adapter 100, the charging power input by the adapter 100 is received and transmitted to the charging circuit 300. When the first electrode plate 202 of the charging circuit 300 is connected to the device to be charged and the charging power is received, the charging circuit 300 outputs the charging power to the device to be charged through the first electrode plate 202 for charging. It can connect different types of adapters and adapt to different models of devices to be charged, improving the practicability of the charging pile.

[0056] In an exemplary embodiment, the charging circuit 300 is further used to stop outputting the charging power to the device to be charged when the multiple charging interfaces 201 are simultaneously connected to the adapter 100.

[0057] In this embodiment, when the charging circuit 300 detects that the multiple charging interfaces 201 are completely connected to the corresponding adapters 100, it stops outputting the charging power by controlling the first electrode plate 202, thereby stopping charging the device to be charged, which can solve the problem of abnormal power transmission when multiple interfaces are connected and improve the safety of the charging pile.

[0058] In an exemplary embodiment, as Figure 2As shown, each charging interface 201 is also used to output a voltage detection signal when connected to the adapter 100. Among them, the voltage detection signals output by multiple charging interfaces are different. The charging circuit 300 further includes: a central controller 301, connected to multiple charging interfaces 201, and configured to output a charging control signal when receiving the voltage detection signal; a charging controller 302, connected to multiple charging interfaces 201, the central controller 301, and the first electrode plate 202, and configured to transmit the charging power to the first electrode plate 202 when receiving the charging control signal, so as to output the charging power through the first electrode plate 202 to charge the device to be charged.

[0059] Among them, when each charging interface 201 is respectively connected to the corresponding adapter 100, different voltage detection signals are respectively output, and the corresponding charging power is transmitted to the charging controller 302. In addition, the voltage detection signal includes an ADC signal, and the ADC signal is used to accurately feedback whether the target charging interface is connected to the corresponding adapter 100. Among them, the target charging interface refers to the charging interface 201 currently connected to the corresponding adapter 100.

[0060] In this embodiment, when one of the charging interfaces 201 is connected to the corresponding adapter 100, the charging interface 201 outputs a voltage detection signal to the central controller 301, and transmits the charging power transmitted by the adapter 100 to the charging controller 302. When the central controller 301 receives the voltage detection signal, it outputs a charging control signal. After the charging controller 302 receives the charging control signal, it conducts the transmission channel for transmitting the charging power, so that the charging power is transmitted to the first electrode plate 202 through the transmission channel, thereby realizing the charging of the device to be charged, and can be applicable to the access of different adapters, thereby improving the practicability of the charging pile.

[0061] Optionally, when the central controller 301 receives the voltage detection signal, it means that the target charging interface has been connected to the adapter 100, and then it outputs a charging control signal. When the central controller 301 does not receive the voltage detection signal, it means that the target charging interface has not been connected to the adapter 100, and then it outputs a charging stop signal for controlling the charging controller 302 not to transmit the charging power. In addition, when the central controller 301 detects that the device to be charged has been charged, it outputs a charging stop signal.

[0062] Optionally, when the central controller 301 receives multiple voltage detection signals, it means that multiple charging interfaces 201 have all been connected to the adapter 100, and it outputs a charging stop signal.

[0063] In an exemplary embodiment, such as Figure 3As shown, the charging circuit 300 further includes a power transmission circuit 303. The power transmission circuit 303 is connected to the charging controller 302 and the first electrode plate 202. The charging controller 302 is connected to a plurality of charging interfaces 201 and the central controller 301. The charging controller 302 is further configured to turn on the power transmission circuit 303 when receiving a charging control signal, so as to transmit the charging power to the first electrode plate 202 through the power transmission circuit 303.

[0064] Wherein, the power transmission circuit 303 can be disposed inside the charging controller 302. When the power transmission circuit 303 is disposed inside the charging controller 302, the first end of the power transmission circuit 303 is connected to the chip built in the charging controller 302, and the second end of the power transmission circuit 303 is connected to the first electrode plate 202. Alternatively, the power transmission circuit 303 can also be disposed between the charging controller 302 and the first electrode plate 202. When the power transmission circuit 303 is disposed between the charging controller 302 and the first electrode plate 202, the first end of the power transmission circuit 303 is connected to the charging controller 302, and the second end of the power transmission circuit 303 is connected to the first electrode plate 202. Alternatively, the power transmission circuit 303 is disposed between the charging interface 201 and the first electrode plate 202. When the power transmission circuit 303 is disposed between the charging interface 201 and the first electrode plate 202, the first end of the power transmission circuit 303 is connected to the charging interface 201, the second end of the power transmission circuit 303 is connected to the first electrode plate 202, and the third end of the power transmission circuit 303 is connected to the charging controller 302. In this application, the installation position and connection mode of the power transmission circuit 303 are not specifically limited.

[0065] In this embodiment, after receiving the charging control signal, the charging controller 302 controls the switch of the power transmission circuit 303 to be turned on, turning on the power transmission circuit 303, so that the charging power is transmitted to the first electrode plate 202 through the power transmission circuit 303, which can accurately control the output of the power and improve the safety of the charging pile.

[0066] Optionally, when receiving the charging control signal, the charging controller 302 controls the power transmission circuit 303 to be turned on, so that the charging power transmitted by the charging interface 201 is transmitted to the first electrode plate 202 after passing through the power transmission circuit 303. In addition, when receiving the charging stop signal, the charging controller 302 controls the power transmission circuit 303 to be turned off, so that the charging power transmitted by the charging interface 201 cannot be transmitted to the first electrode plate 202 through the power transmission circuit 303.

[0067] Optionally, the central controller 301 is further configured to output a charging stop signal when receiving a plurality of voltage detection signals. The charging controller 302 is further configured to stop transmitting the charging power supply to the first electrode sheet 202 when receiving the charging stop signal.

[0068] When a plurality of charging interfaces 201 are connected to corresponding adapters, the plurality of connected charging interfaces 201 all output voltage detection signals to the central controller 301, that is, output a plurality of voltage detection signals to the central controller 301. When the central controller 301 receives the plurality of voltage detection signals, it outputs a charging stop signal to the charging controller 302. When the charging controller 302 receives the charging stop signal, it controls the power transmission circuit 303 to disconnect, and the charging power supply cannot be transmitted to the first electrode sheet 202 through the power transmission circuit 303, thereby stopping charging the device to be charged.

[0069] In an exemplary embodiment, the charging power supply includes a first charging power supply and a second charging power supply. The charging interface 201 includes: a first type charging interface 401, configured to transmit the first charging power supply when connected to a first type of adapter 100. A second type charging interface 402, configured to transmit the second charging power supply when connected to a second type of adapter 100, where the charging modes of the first type charging interface 401 and the second type charging interface 402 are different.

[0070] The charging interface 201 includes a plurality of first type charging interfaces 401 and a plurality of second type charging interfaces 402. The adapter 100 connected to the first type charging interface 401 can implement a compatible charging mode of charging with a downward compatible charging current or an upward compatible charging current. The adapter 100 connected to the second type charging interface 402 can implement a fixed charging mode of charging with a fixed charging current. Among them, the downward compatible charging current means that the adapter 100 is compatible with a lower current, and the upward compatible charging current means that the adapter 100 is compatible with a higher current.

[0071] When there are a plurality of first type charging interfaces 401, the adapters 100 connected to different first type charging interfaces 401 are different. Among the plurality of adapters 100 connected to different first type charging interfaces 401, the compatible charging currents are different, or the compatible functions are different, that is, the function of upward compatible charging current or downward compatible charging current, or the charging parameters are different, that is, one or more of charging current, charging voltage, charging power, etc. are different. Similarly, when there are a plurality of second type charging interfaces 402, the adapters 100 connected to different second type charging interfaces 402 are different. Among the plurality of adapters 100 connected to different second type charging interfaces 402, the charging parameters are different.

[0072] In addition, the charging mode further includes a fast charging mode. The charging interface 201 further includes a third type of charging interface. The adapter 100 connected to the third type of charging interface stores a fast charging protocol for implementing fast charging, and can implement a fast charging mode with a fast charging function. In the case where there are multiple third type of charging interfaces, the adapters 100 connected to different third type of charging interfaces are different. Among the multiple adapters 100 connected to different third type of charging interfaces, the stored fast charging protocols are different, or the charging parameters are different.

[0073] In this embodiment, after the first type of charging interface 401 completes the connection with the adapter 100, the first charging power supply and the compatibility control instruction are transmitted to the charging circuit 300. After the charging circuit 300 receives the compatibility control instruction, it starts the corresponding compatibility charging mode, adjusts the first charging power supply to the charging current adapted to the device to be charged, and charges the device to be charged through the first electrode plate 202. After the second type of charging interface 402 completes the connection with the adapter 100, the second charging power supply is transmitted to the charging circuit 300. After the charging circuit 300 receives the second charging power supply, it charges the device to be charged through the first electrode plate 202, which can be compatible with different charging modes and different charging parameters, and improves the flexibility and practicability of the charging device.

[0074] Optionally, the charging power supply further includes a third charging power supply. After the third type of charging interface completes the connection with the adapter 100, the third charging power supply and the corresponding fast charging protocol are transmitted to the charging circuit 300. After the charging circuit 300 receives the fast charging protocol, it starts the corresponding fast charging mode, adjusts the third charging power supply to the charging current adapted to the device to be charged, and charges the device to be charged through the first electrode plate 202.

[0075] In an exemplary embodiment, as Figure 4 shown, the charging control signal includes a first charging control signal, the voltage detection signal includes a first voltage detection signal. The first type of charging interface 401 is further used to output a compatibility control signal. The charging circuit 300 further includes: a CAN transceiver 304, connected to the first type of charging interface 401 and the central controller 301, and transmits the compatibility control signal when the first type of charging interface 401 is connected to the adapter 100. The central controller 301 is connected to the first type of charging interface 401 and is used to output the first charging control signal when receiving the compatibility control signal and the first voltage detection signal. The charging controller 302 is further used to transmit the first charging power supply to the first electrode plate 202 when receiving the first charging control signal, so as to output the first charging power supply through the first electrode plate 202 to charge the device to be charged.

[0076] Among them, a CAN communication unit is provided inside the first-type charging interface 401. The CAN transceiver 304 is used to implement CAN communication between the first-type charging interface 401 and the central controller 301, that is: the first-type charging interface 401 transmits a compatibility control signal to the CAN transceiver 304 through the CAN communication unit, and the CAN transceiver 304 transmits the compatibility control signal to the central controller 301 through the built-in CAN bus communication protocol. After receiving the compatibility control signal, the central controller 301 obtains an indication to enter the compatibility charging mode, obtains the value of the corresponding charging current according to the model of the device to be charged, and outputs a corresponding first charging control signal according to the value of the charging current.

[0077] In addition, an existing compatibility charging control method is stored in the central controller 301 for controlling the compatibility charging of the device to be charged. After the first-type charging interface 401 is connected to the corresponding adapter 100, the compatibility control signal is transmitted to the CAN transceiver 304 through the internally provided CAN communication unit. When the CAN transceiver 304 receives the compatibility control signal, it transmits the compatibility control signal to the central controller 301. After receiving the compatibility control signal, the central controller 301 calls the existing compatibility charging control method, obtains the value of the charging current adapted to the device to be charged according to the model of the device to be charged, and outputs a corresponding first charging control signal to the charging controller 302 according to the value of the charging current. Among them, the central controller 301 can obtain the model of the device to be charged through single-point communication after connecting the first electrode piece 202 to the device to be charged.

[0078] In this embodiment, when the first-type charging interface 401 is connected to the corresponding adapter 100, the first-type charging interface 401 transmits a first voltage detection signal to the central controller 301, and transmits a compatibility control signal to the central controller 301 through the CAN transceiver 304. After receiving the compatibility control signal and the first voltage detection signal, the central controller 301 obtains the value of the charging current adapted to the device to be charged according to the model of the device to be charged, and generates and outputs a corresponding first charging control signal to the charging controller 302 according to the value of the charging current. When the charging controller 302 receives the corresponding first charging control signal, it adjusts the first charging power supply to the charging current adapted to the device to be charged, and turns on the power transmission circuit 303, so that the charging current adapted to the device to be charged passes through the power transmission circuit 303 and then charges the device to be charged quickly through the first electrode piece 202, which can realize the compatibility charging of the device to be charged and improve the practicability of the charging pile.

[0079] In an exemplary embodiment, such as Figure 5As shown, the charging control signal includes a second charging control signal, and the voltage detection signal includes a second voltage detection signal. The central controller 301 is connected to the second type charging interface 402, and is further configured to output a second charging control signal when receiving the second voltage detection signal. The charging controller 302 is further configured to transmit the second charging power supply to the first electrode plate 202 when receiving the second charging control signal, so as to output the second charging power supply through the first electrode plate 202 to charge the device to be charged.

[0080] In this embodiment, when the second type charging interface 402 is connected to the adapter 100, the second type charging interface 402 transmits the second voltage detection signal to the central controller 301. After receiving the second voltage detection signal, the central controller 301 completes the interface detection and outputs the second charging control signal to the charging controller 302. When receiving the second charging control signal, the charging controller 302 turns on the power transmission circuit 303 for transmitting the second charging power supply, so that the second charging power supply is transmitted to the first electrode plate 202 after passing through the power transmission circuit 303. The first electrode plate 202 outputs the second charging power supply to charge the device to be charged, which can realize the normal charging of the device to be charged and improve the practicability of the charging pile.

[0081] In an exemplary embodiment, the charging control signal includes a third charging control signal, the voltage detection signal includes a third voltage detection signal, and the third type charging interface is further configured to transmit the fast charging protocol data of the adapter 100. The CAN transceiver 304 transmits the fast charging protocol data when the third type charging interface is connected to the adapter 100. The central controller 301 is connected to the third type charging interface and is configured to output a third charging control signal when receiving the fast charging protocol data and the third voltage detection signal. The charging controller 302 is further configured to transmit the third charging power supply to the first electrode plate 202 when receiving the third charging control signal, so as to output the third charging power supply through the first electrode plate 202 to charge the device to be charged.

[0082] Wherein, a CAN communication unit is arranged inside the third type charging interface. The CAN transceiver 304 is used to implement CAN communication between the third type charging interface and the central controller 301, that is: the third type charging interface transmits the fast charging protocol data to the CAN transceiver 304 through the CAN communication unit. The CAN transceiver 304 converts the fast charging protocol data into corresponding electrical signals and transmits the electrical signals to the central controller 301 through the built-in CAN bus communication protocol. After receiving the electrical signals, the central controller 301 parses the electrical signals to obtain the fast charging protocol data, performs protocol matching according to the fast charging protocol data and the fast charging protocol adapted to the device to be charged, and outputs the corresponding third charging control signal after successful protocol matching.

[0083] In addition, an existing fast charging protocol matching method is stored in the central controller 301 for controlling the fast charging of the device to be charged. After the third type of charging interface is connected to the corresponding adapter 100, the fast charging protocol data is transmitted to the CAN transceiver 304 through the internally provided CAN communication unit. When the CAN transceiver 304 receives the fast charging protocol data, it converts the fast charging protocol data into corresponding electrical signals and then transmits them to the central controller 301. After receiving the electrical signals, the central controller 301 analyzes the electrical signals to obtain the fast charging protocol data, calls the existing fast charging protocol matching method, matches the fast charging protocol data with the fast charging protocol adapted to the device to be charged, and outputs a corresponding third charging control signal to the charging controller 302 after successful protocol matching. Among them, the fast charging protocol adapted to the device to be charged is obtained after being connected to the device to be charged through the first electrode 202, and the first electrode 202 transmits it to the central controller 301 after obtaining the fast charging protocol adapted to the device to be charged.

[0084] In this embodiment, when the third type of charging interface is connected to the corresponding adapter 100, the third type of charging interface transmits a third voltage detection signal to the central controller 301 and transmits the fast charging protocol data to the central controller 301 through the CAN transceiver 304. After receiving the fast charging protocol data and the third voltage detection signal, the central controller 301 performs protocol matching according to the fast charging protocol data and the fast charging protocol adapted to the device to be charged, and outputs a corresponding third charging control signal to the charging controller 302 after the protocol matching is completed. When the charging controller 302 receives the corresponding third charging control signal, it adjusts the third charging power supply to the charging current adapted to the device to be charged and turns on the power transmission circuit 303, so that the charging current adapted to the device to be charged passes through the power transmission circuit 303 and then charges the device to be charged quickly through the first electrode 202, which can realize the fast charging of the device to be charged and improve the practicability of the charging pile.

[0085] In an exemplary embodiment, as Figure 6 shown, the charging circuit 300 further includes: a temperature detection unit, connected to the central controller 204, for detecting the temperature of the first electrode 202 and outputting a temperature detection signal. The central controller 301 is further configured to output a charging stop signal to the charging controller 302 when the temperature value corresponding to the temperature detection signal is greater than a preset temperature threshold. The charging controller 302 is further configured to stop transmitting the charging power supply to the first electrode 202 when receiving the charging stop signal.

[0086] Among them, the temperature detection unit can be any type of temperature sensor, such as a thermistor sensor, a thermocouple sensor, a platinum resistance temperature sensor, and an integrated temperature sensor, etc. Exemplarily, when the temperature detection unit is a thermocouple sensor, the obtained temperature detection signal is a voltage value. The central controller 301 can determine whether the voltage value is within a preset range, thereby determining whether the temperature value of the first electrode plate 202 is within the safe temperature range.

[0087] It can be understood that the temperature detection unit can be arranged inside the first electrode plate 202, or embedded in the outer surface of the first electrode plate 202, or arranged at any position that can accurately detect the temperature of the first electrode plate 202. The position of the temperature detection unit is not limited in this application.

[0088] In this embodiment, during the charging process, the first electrode plate 202 uses the built-in temperature detection unit to detect its own temperature in real time and feedback a temperature detection signal to the central controller 301 in real time. When the central controller 301 receives the temperature detection signal, it makes a safety judgment on the temperature of the first electrode plate 202 according to the temperature value corresponding to the temperature detection signal. When the temperature of the first electrode plate 202 is not within the safe temperature range, it outputs a charging stop signal to the charging controller 302. When the charging controller 302 receives the charging stop signal, it stops transmitting the charging power supply to the first electrode plate 202, which can detect the temperature of the electrode plate in real time during the charging process and improve the safety during the charging process.

[0089] Optionally, when the central controller 301 detects that the temperature of the first electrode plate 202 is greater than the preset temperature threshold, it outputs a charging stop signal to the charging controller 302 to make the charging controller 302 stop charging.

[0090] In an exemplary embodiment, as Figure 6 shown, a current detection unit and a voltage detection unit are provided in the charging controller 302. The current detection unit is used to detect the current of the transmitted charging power supply in real time, and the voltage detection unit is used to detect the voltage of the transmitted charging power supply in real time.

[0091] Among them, the current detection unit can include any type of current sensor, such as a resistance shunt, a current transformer (CT), a Hall current sensor, an optical fiber current sensor, etc. The voltage detection unit can include any type of voltage sensor, such as a resistance voltage divider, a capacitor voltage divider, an electromagnetic voltage transformer, a capacitive voltage transformer, a Hall voltage sensor, etc.

[0092] It can be understood that the current detection unit is connected to the port where the charging controller 302 outputs the charging power supply to the first electrode plate 202, and the voltage detection unit is connected to the port where the charging controller 302 outputs the charging power supply to the first electrode plate 202.

[0093] During the charging process, the current detection unit detects the current of the charging power supply in real time and feeds back a current detection signal to the central controller 301 in real time. When the central controller 301 receives the current detection signal, it makes a safety judgment on the current of the charging power supply according to the current value corresponding to the current detection signal. When the current of the charging power supply is not within the safe current range, it outputs a charging stop signal to the charging controller 302. In addition, the voltage detection unit detects the voltage of the charging power supply in real time and feeds back a voltage detection signal to the central controller 301 in real time. When the central controller 301 receives the voltage detection signal, it makes a safety judgment on the voltage of the charging power supply according to the voltage value corresponding to the voltage detection signal. When the voltage of the charging power supply is not within the safe voltage range, it outputs a charging stop signal to the charging controller 302.

[0094] In an exemplary embodiment, as Figure 6 shown, the device to be charged 500 includes a second electrode plate 501. When the second electrode plate 501 is in contact with the first electrode plate 202, the device to be charged 500 and the charging pile 200 can perform single-point handshake communication, that is, the charging pile 200 sends a handshake signal to the device to be charged 500 through the single bus every preset time interval. And when the response signal replied by the device to be charged 500 through the single bus is detected, it means that the handshake is successful and indicates that the first electrode plate 202 and the second electrode plate 501 are in place in contact.

[0095] In addition, after the first electrode plate 202 and the second electrode plate 501 are in close contact, when the first electrode plate 202 receives the first charging power supply transmitted by the charging controller 302, the first electrode plate 202 directly transfers the first charging power supply to the second electrode plate 501, so that the device to be charged 500 charges the internal battery through the first charging power supply. Similarly, when the first electrode plate 202 receives the second charging power supply transmitted by the charging controller 302, the first electrode plate 202 directly transfers the second charging power supply to the second electrode plate 501, so that the device to be charged 500 charges the internal battery through the second charging power supply.

[0096] It should be noted that the positive electrode piece NIC of the first electrode piece 202 is connected to the positive electrode piece NIC of the second electrode piece 501, and the negative electrode piece NIC of the first electrode piece 202 is connected to the negative electrode piece NIC of the second electrode piece 501. Only when the connection between the positive electrode piece NIC and the negative electrode piece NIC is completed can the first electrode piece 202 transmit the charging power supply to the second electrode piece 501.

[0097] In this embodiment, after the first electrode piece 202 of the charging pile 200 is in close contact with the second electrode piece 501 of the device to be charged 500, and when the positive electrode piece NIC of the first electrode piece 202 is connected to the positive electrode piece NIC of the second electrode piece 501 and the negative electrode piece NIC of the first electrode piece 202 is connected to the negative electrode piece NIC of the second electrode piece 501, the charging pile 200 outputs a handshake signal to the device to be charged 500 through the first electrode piece 202 and the second electrode piece 501. When the charging pile 200 receives the response signal replied by the device to be charged 500, it means that the charging pile 200 has completed the handshake communication with the device to be charged 500, and it also means the detection that the contact between the first electrode piece 202 and the second electrode piece 501 is in place, which can improve the stability of the charging pile during charging.

[0098] It should be noted that when the charging pile 200 has completed the handshake communication with the device to be charged 500, a lot of data information can be transmitted between the charging pile 200 and the device to be charged 500. For example, the device to be charged 500 can obtain the charging capacity of the charging pile 200, and the charging pile 200 can obtain the model of the device to be charged 500, etc. The data information transmitted in this application is not specifically limited.

[0099] In an exemplary embodiment, when the first electrode piece 202 of the charging pile 200 is not in close contact with the second electrode piece 501 of the device to be charged 500, the charging pile 200 will not output a handshake signal to the device to be charged 500 through the first electrode piece 202, and the device to be charged 500 will not reply a response signal when it does not receive the handshake signal. Or, when the positive electrode piece NIC of the first electrode piece 202 is not connected to the positive electrode piece NIC of the second electrode piece 501, the charging pile 200 will not output a handshake signal to the device to be charged 500 through the first electrode piece 202, and the device to be charged 500 will not reply a response signal when it does not receive the handshake signal. Or, when the negative electrode piece NIC of the first electrode piece 202 is not connected to the negative electrode piece NIC of the second electrode piece 501, the charging pile 200 will not output a handshake signal through the first electrode piece 202. When the charging pile 200 does not receive the handshake signal, it will not reply a response signal, which can improve the stability of the charging pile during charging.

[0100] In an exemplary embodiment, the charging circuit 300 further includes a U-shaped photoelectric sensor. The U-shaped photoelectric sensor is connected to the central controller 301. A trigger piece is connected to the first electrode sheet 202. The trigger piece can move along with the first electrode sheet 202. The U-shaped photoelectric sensor can be arranged at a position on the moving path of the trigger piece. The application does not specifically limit the position where the photoelectric sensor is arranged.

[0101] When the first electrode sheet 202 is in close contact with the second electrode sheet 501, the position of the trigger piece moves to block or change the propagation path of the light emitted by the photoelectric sensor. When the photoelectric sensor detects that the propagation path of the emitted light is changed or blocked, it sends a signal to the central controller 301. When the central controller 301 receives this signal, it confirms that the first electrode sheet 202 and the second electrode sheet 501 are in place in contact.

[0102] In an exemplary embodiment, as Figure 7 shown, the power transmission circuit 303 includes a power control switch. The charging controller 302 is further configured to output a conduction control signal when receiving a charging control signal. The power control switch is further configured to conduct when receiving the conduction control signal.

[0103] Wherein, the power control switch is the mos transistor switch Q4 as Figure 7 shown. In addition, the power control switch includes a MOS transistor, a triode, or a switching circuit, etc., which can conduct when receiving a conduction control signal and disconnect when receiving a disconnection control signal. The application does not specifically limit the power control switch.

[0104] In this embodiment, after receiving the charging control signal, the charging controller 302 outputs a conduction control signal to the power control switch. The power control switch conducts when receiving the conduction control signal. After receiving the charging stop signal, the charging controller 302 outputs a disconnection control signal to the power control switch. The power control switch disconnects when receiving the disconnection control signal, which can accurately control the conduction or disconnection of the switch and improve the accuracy of charging power transmission.

[0105] Specifically, when the power control switch is a mos transistor switch, the port of the charging controller 302 for transmitting the charging power is connected to the source electrode of the mos transistor switch. The port of the charging controller 302 for transmitting the conduction control signal or the disconnection control signal is connected to the gate electrode of the mos transistor switch. The first electrode sheet 202 is connected to the drain electrode of the mos transistor switch.

[0106] After receiving the charging control signal, the charging controller 302 outputs a conduction control signal to the gate of the MOS transistor switch and transmits the charging power supply to the source of the MOS transistor switch, causing the MOS transistor switch to conduct. The charging power supply is transmitted from the source of the MOS transistor switch to the drain of the MOS transistor switch and then to the first electrode plate 202. In addition, after receiving the charging stop signal, the charging controller 302 outputs a disconnection control signal to the gate of the MOS transistor switch, causing the MOS transistor switch to disconnect, and the charging power supply cannot be transmitted through the source of the MOS transistor switch.

[0107] In an exemplary embodiment, as Figure 7 shown, the charging circuit 300 further includes isolation diodes. The isolation diodes are connected to the charging interface 201 and are used to isolate other charging interfaces 201 when one of the charging interfaces 201 is connected to the adapter 100.

[0108] Among them, the isolation diodes are such as Figure 7 the ideal diode Q1, the ideal diode Q2, and the ideal diode Q3 in. During the charging process of connecting different adapters 100 to the corresponding charging interfaces 201, they prevent voltage backflow to other charging interfaces 201 and avoid damage to other charging interfaces 201.

[0109] As Figure 7 shown, the following takes the specific circuits of three chargings as an example to specifically illustrate the charging pile.

[0110] In Figure 7 the first type of charging interface 401 includes a CH1 interface and a CAN communication unit. The CH1 interface is used to connect an adapter with an output current of 15A. In Figure 7 the second type of charging interface 402 includes a CH2 interface and a CH3 interface. The CH2 interface is used to connect an adapter with an output current of 8A, and the CH3 interface is used to connect an adapter with an output current of 3.3A. In Figure 7 the charging controller 302 includes a charging control chip, and the model of the charging control chip includes BQ76200. The model of the charging control chip is not specifically limited in this application.

[0111] Specifically, when a 15A adapter is connected to the CH1 interface, after the central controller 301 completes the handshake communication with the device to be charged, it obtains the model of the device to be charged 500 through single-point communication with the first electrode plate 202, and obtains the charging parameters adapted to the device to be charged 500 based on the model of the device to be charged 500. The central controller 301 feeds back the charging parameters adapted to the device to be charged 500 to the charging controller 302. The charging controller 302 adjusts the charging power input by the 15A adapter according to the charging parameters adapted to the device to be charged 500, and charges the device to be charged 500 through the first electrode plate 202 according to the adjusted charging power.

[0112] When an 8A adapter is connected to the CH2 interface, or when a 3.3A adapter is connected to the CH3 interface, the central controller 301 controls the power transmission circuit 303 to conduct, so as to charge the device to be charged 500 through the first electrode plate 202 according to the corresponding charging power.

[0113] In addition, an ideal diode is connected to each of the CH1 interface, CH2 interface, and CH3 interface in the charging circuit 300. The ideal diode is used for isolation, that is: when an adapter is connected to one of the CH1 interface, CH2 interface, and CH3 interface, the other two charging interfaces are isolated, and there is no voltage on the other two charging interfaces, which can prevent the voltage from flowing back during the charging process when different adapters are connected, and improve the safety during the charging process. Among them, as Figure 7 shown, the CH1 interface is connected to the ideal diode Q1, the CH2 interface is connected to the ideal diode Q2, and the CH3 interface is connected to the ideal diode Q3.

[0114] As Figure 7 shown, the charging circuit 300 further includes a control lamp board. Three lamps of the control lamp board are connected to the central controller 301 and are used to receive the GPIO control signal of the central controller 301, such as Figure 7 the control lamp board B1 in. The control lamp board B1 is used to receive the GPIO control signal during the charging process and display different charging states when receiving the GPIO control signal. For example, when it is detected that multiple adapters are inserted, the red and green lights are lit simultaneously, alternating at a specific brightness and time interval, and then the yellow light flashes to indicate that multiple adapters are inserted.

[0115] As Figure 7 shown, the charging circuit 300 further includes a Bluetooth communication module. The Bluetooth communication module is such as Figure 7 the communication module M1 in. The communication module M1 is used to realize data communication between the charging pile and the device to be charged, and can transmit, for example, charging status, charging pile software upgrade package, and charging scheduling information between multiple charging piles and multiple devices to be charged, etc. This application does not specifically limit this.

[0116] As Figure 7 shown, the charging circuit 300 further includes a first DC-DC converter, such as the DC-DC converter that outputs a 12V voltage in Figure 7 . The first DC-DC converter is used to connect to the first electrode plate 202 and the control lamp board B1, convert the charging power input from the charging interface into a 12V voltage, and transmit the 12V voltage to the first electrode plate 202 and the control lamp board B1 for supplying power to the first electrode plate 202 and the control lamp board B1.

[0117] As Figure 7 shown, the charging circuit 300 further includes a second DC-DC converter and an LDO voltage regulator. The second DC-DC converter is such as the DC-DC converter that outputs a 5V voltage in Figure 7 . The second DC-DC converter is used to connect to the LDO voltage regulator, and the LDO voltage regulator is used to connect to the central controller 301 and the Bluetooth communication module for supplying power to the central controller 301 and the Bluetooth communication module.

[0118] In addition, in an exemplary embodiment, the connector end of the adapter uses a long and short pin design. The positive and negative pin feet output by the adapter are 5mm longer than the detection pin feet, and at the same time, the detection pin feet are connected to the negative pole of the adapter. At the end of the device to be charged, the detection pin feet are finally connected to the IO port of the central controller, and at the same time, the detection interface at the end of the device to be charged is default in a pulled-up state. When the connector of the adapter is inserted, first, the positive and negative pin feet of the adapter come into contact. At this time, since the detection pin feet are shorter and have not come into contact yet, the device to be charged does not detect the insertion of the adapter. Therefore, the central controller does not output a charging control signal to turn on the charging controller. When the detection pin feet come into contact with each other, the central controller will detect that the level at the detection pin feet is pulled low. At this time, the positive and negative pin feet of the adapter have already come into full contact. Therefore, there will be no arcing due to poor contact, and the access protection contacts are not easily oxidized, improving the practicality of the charging interface.

[0119] It can be understood that the above charging pile and charging system can also adopt other forms, rather than being limited to the forms already mentioned in the above embodiments, as long as it can achieve the function of completing the connection of different types of adapters, adapting different models of robots for charging, and improving the practicality of the charging pile.

[0120] The above charging pile and charging system can be applied to charging piles for electric devices such as automobiles, robots, and drones.
