[0055] It should be noted that like reference numerals and characters refer to like items in the following attached drawings, and therefore, once an item is defined in one attached drawing, that item need not be further discussed in subsequent attached drawings.

[0056] <Hardware configuration>

[0057] FIG. 1 is a schematic structural diagram of a charging socket component in which an embodiment of the present disclosure can be implemented.

[0058] As shown in FIG. 1 , the charging socket component 1000 in this embodiment may include a charging socket 1100, a heating device 1200, a foreign object detection sensor 1300, a camera 1400, a temperature sensor 1500, and a controller 1600.

[0059] The charging socket 1100 in this embodiment may be an integrated charging socket in which an AC charging socket and a DC charging socket are integrated, or may include an AC charging socket and a DC charging socket arranged in a single charging port.

[0060] The heating device 1200 in this embodiment can include a heating component 1210 and a heat conducting component 1220 .

[0061] The heating component 1210 is configured to convert electrical energy into thermal energy and heat the charging socket 1100 with the generated thermal energy.

[0062] In one example, the heating component 1210 may be a heating patch that has good thermal insulation properties, meets a certain pressure resistance level, and has a relatively high thermal conductivity.

[0063] In another example, the heating component 1210 may alternatively be a heating resistor.

[0064] The thermal conduction component 1220 may be configured to absorb heat emitted by the DC charging conductor, recycle the heat, and heat the charging socket 1100. Specifically, the thermal conduction component 1220 can transfer thermal energy generated during vehicle charging to the charging socket 1100 to heat the charging socket 1100.

[0065] The DC charging conductor connected to the heat conducting component 1220 may be a cable in a DC charging loop, specifically, a copper wire, an aluminum wire, an aluminum rod, a copper rod, a copper bar, an aluminum bar, etc. Aluminum rods, copper rods, copper bars, and aluminum bars have good heat dissipation performance and can conduct heat well to the heat conducting component 1220.

[0066] A thermally conductive material with high thermal conductivity, such as a thermally conductive adhesive (liquid) or a thermally conductive mud, may be placed between the thermally conductive component 1220 and the DC charging conductor, so that the heat in the DC charging conductor can be transferred to the thermally conductive component 1220 for recycling.

[0067] Foreign object detection sensor 1300 may be configured to detect whether a foreign object is attached to charging socket 1100.

[0068] The camera 1400 is configured to photograph the charging socket 1100 and obtain a first image, whereby the vehicle determines whether the foreign object attached to the charging socket 1100 is a detachable object according to the first image.

[0069] The temperature sensor 1500 is configured to detect the temperature of the charging socket 1100 .

[0070] The controller 1600 is configured to comprehensively determine whether the charging socket has a loose object according to the data collected by the foreign object detection sensor 1300, the camera 1400 and the temperature sensor 1500, and if it is determined that the charging socket has a loose object, selects a heating component from the heating device 1200 that corresponds to the vehicle's charging type, i.e., the heating component 1210 or the heat conduction component 1220, to heat the charging socket 1100 so that the loose object in the charging socket 1100 is thawed.

[0071] <Embodiments of the Method>

[0072] 2 illustrates a method for heating a charging socket, according to one embodiment. In one example, the method may be implemented by a vehicle, which may include the charging socket component 1000 shown in FIG. 1, and the method may be implemented by the controller 1600 shown in FIG. 1.

[0073] As shown in FIG. 2, the method for heating a charging socket according to this embodiment may include the following steps S2100 to S2300.

[0074] Step S2100: The charging type of the vehicle is determined.

[0075] The charge types may include a first charge type and a second charge type, where the first charge type is different from the second charge type.

[0076] In this embodiment, the charging type of the vehicle may be the first charging type or the second charging type.

[0077] In one embodiment of the present disclosure, the first charging type includes a first DC charging, the second charging type includes an AC charging and a second DC charging, and the power of the first DC charging is greater than the power of the second DC charging.

[0078] In one embodiment of the present disclosure, determining the charging type of the vehicle may include: determining that the charging type of the vehicle is AC charging if the first resistance value is a first target value, wherein the first resistance value is a first resistor value corresponding to AC charging; determining that the charging type is first DC charging if the second resistance value is a second target value and heat generated by charging the vehicle is equal to or greater than a preset thermal threshold; or determining that the charging type is second DC charging if the second resistance value is a second target value and heat generated by charging the vehicle is less than the thermal threshold, wherein the second resistance value is a second resistor value corresponding to DC charging.

[0079] In this embodiment, the first resistor may be a resistor connected between the first pin and the ground pin of the charging socket, and the second resistor may be a resistor connected between the second pin and the ground pin of the charging socket.

[0080] When the vehicle is charging with AC power by connecting the AC charging plug to the charging socket, the first resistance value is a first target value. When the vehicle is not charging with AC power, the first resistor is not powered and the first resistance value may be infinite.

[0081] When the vehicle is performing DC charging by connecting the DC charging plug to the charging socket, the second resistance value is a second target value. When the vehicle is not performing DC charging, the second resistor is not powered and the second resistance value may be infinite.

[0082] If the second resistance value is the second target value, it can be determined that the charging socket is connected to the DC charging plug and the charging type of the vehicle is the first DC charging or the second DC charging.

[0083] Whether the charging type is the first DC charging or the second DC charging can be determined according to the heat generated during charging of the vehicle.

[0084] The heat generated during charging of the vehicle can be determined using the following formula: Q=I 2 Rt

[0085] Q is the heat generated during vehicle charging, I is the instantaneous current during charging, R is the resistance of the specific resistance of the cable in the DC charging loop, and t is the charging time.

[0086] If the heat generated in the process of charging the vehicle is equal to or greater than a preset heat threshold, the charging type is determined to be a first DC charging. If the heat generated in the process of charging the vehicle is less than the heat threshold, the charging type is determined to be a second DC charging.

[0087] Step S2200: A heating component corresponding to the charging type is selected from heating devices corresponding to the charging type of the vehicle to function as a target heating device. The heating device includes a heat conduction component and a heating component, and the heat conduction component is configured to conduct thermal energy generated during charging of the vehicle to the charging socket to heat the charging socket. The heating component is configured to heat the charging socket.

[0088] In one embodiment of the present disclosure, selecting a heating component corresponding to the charging type to function as the target heating device from heating devices according to the charging type of the vehicle may include: selecting a heat conduction component as the target heating device when the charging type of the vehicle is a first charging type, and selecting a heating component as the target heating device when the charging type of the vehicle is a second charging type.

[0089] Step S2300: The target heating device is controlled to heat the charging socket.

[0090] If the target heating device is a heating component, the heating component can be controlled to convert electrical energy into thermal energy and heat the charging socket.

[0091] When the vehicle is using AC charging or a low-power secondary DC charge, the DC charging conductors may not generate enough heat to heat the charging socket, so the heating component must additionally begin to heat the charging socket.

[0092] When the target heating device is a heat-conducting component, the heat-conducting component can be controlled to conduct thermal energy generated in the process of charging the vehicle to the charging socket and heat the charging socket.

[0093] When a vehicle is charged with a high-power first DC current, the thermal energy generated in the process of charging the vehicle may include thermal energy generated by the DC charging conductor. When a vehicle is charged with a high-power first DC current, the charging current becomes relatively large, and in this case, the heat generated by the DC charging conductor increases rapidly. The thermal energy generated by the DC charging conductor is used to heat the charging socket, so that the energy can be recycled and effectively reused.

[0094] In one embodiment of the present disclosure, controlling the target heating device to heat the charging socket may include: controlling the heating component to heat the AC charging socket when the charging type is AC charging, controlling the heating component to heat the DC charging socket when the charging type is second DC charging, and controlling the heat conduction component to heat the DC charging socket when the charging type is first DC charging.

[0095] In this embodiment, the heating component for heating the DC charging socket and the heating component for heating the AC charging socket may be the same heating component or different heating components.

[0096] When the heating component for heating the AC charging socket is a first heating component and the heating component for heating the DC charging socket is a second heating component, the first heating component can be positioned near the AC charging socket to heat the AC charging socket, and the second heating component can be positioned near the DC charging socket to heat the DC charging socket.

[0097] According to an embodiment of the present disclosure, a heating component corresponding to a vehicle's charging type is selected from the heating devices to function as a target heating device, and the target heating device is controlled to heat the charging socket, thereby solving the problem that the charging connector is frozen and cannot be pulled out during the process of charging the vehicle. In addition, the vehicle's charging type is distinguished, and different heating components are controlled to heat the charging socket, so that the energy for heating the charging socket can be appropriately allocated.

[0098] In one embodiment of the present disclosure, controlling the target heating device to heat the charging socket may include: controlling the target heating device to heat the charging socket if a heating command is received.

[0099] In this embodiment, the vehicle or the terminal device configured to control the vehicle may be provided with a one-click heating button, and when the charging socket has a loose object, the user can click the one-click heating button to trigger a heating command.

[0100] In one embodiment of the present disclosure, the method may further include: determining whether the charging socket has a loose object and controlling the target heating device to heat the charging socket may include: if the charging socket has a loose object, controlling the target heating device to heat the charging socket.

[0101] In this embodiment, whether the charging socket has a loose object may be determined according to a preset first frequency. The first frequency may be preset according to an application scenario or specific requirements. For example, the first frequency may be every minute.

[0102] In one embodiment of the present disclosure, determining whether the charging socket has a soluble object may include: controlling a camera to photograph the charging socket and obtain a first image; and receiving the first image, and determining whether the foreign object is a soluble object according to the first image.

[0103] In this embodiment, the camera can be placed near the charging socket and can take a picture of the charging socket.

[0104] Specifically, the first image can be compared with a preset image of a solvable object to determine whether the first image includes a solvable object, and if the first image includes a solvable object, it is determined that the charging socket has a solvable object. If the first image does not include a solvable object, it is determined that the charging socket does not have a solvable object.

[0105] In one embodiment of the present disclosure, determining whether the charging socket has a loose object may include: receiving sensor data collected by a foreign object detection sensor; determining whether the charging socket has a foreign object according to the sensor data; if the charging socket has a foreign object, controlling a camera to photograph the charging socket and obtain a first image; and receiving the first image and determining whether the foreign object is a loose object according to the first image.

[0106] In this embodiment, the foreign object detection sensor and the camera detect whether the charging socket has a loose object, thereby making the detection result more accurate. In addition, if it is determined that the charging socket has a foreign object according to the sensor data collected by the foreign object detection sensor, it is determined whether the foreign object is a loose object according to the first image acquired by photographing the charging socket with the camera, thereby reducing the power consumption of the vehicle.

[0107] In one embodiment of the present disclosure, the method may further include: determining whether the charging socket has a loose object and whether the current temperature of the charging socket is equal to or less than a preset first temperature threshold, and controlling the target heating device to heat the charging socket may include: if the charging socket has a loose object and the current temperature of the charging socket is equal to or less than the first temperature threshold, controlling the target heating device to heat the charging socket.

[0108] In one example, determining whether the charging socket has a loose object and whether the current temperature of the charging socket is equal to or less than a preset first temperature threshold may include: controlling a camera to photograph the charging socket and obtain a first image; receiving the first image and determining whether the charging socket has a loose object according to the first image; and if the charging socket has a loose object, controlling a temperature sensor to obtain the current temperature of the charging socket and determining whether the current temperature of the charging socket is equal to or less than the first temperature threshold.

[0109] In another example, determining whether the charging socket has a loose object and whether the current temperature of the charging socket is equal to or less than a predetermined first temperature threshold may include: receiving sensor data collected by a foreign object detection sensor; determining whether the charging socket has a foreign object according to the sensor data; if the charging socket has a foreign object, controlling a camera to photograph the charging socket and obtain a first image, and receiving the first image and determining according to the first image whether the foreign object is a loose object; and if the charging socket has a loose object, controlling a temperature sensor to obtain a current temperature of the charging socket and determining whether the current temperature of the charging socket is equal to or less than a first temperature threshold.

[0110] In this embodiment, the first temperature threshold may be preset according to application scenarios or specific requirements, for example, the first temperature threshold may be 0 degrees Celsius.

[0111] In this embodiment, if the charging socket has a foreign object, and it is detected that the foreign object in the charging socket is a loose object according to the first image obtained by photographing the charging socket, and it is detected that the temperature of the charging socket is below the first temperature threshold, the loose object in the charging socket is comprehensively identified, and a thermal event of the charging socket is triggered to occur, which can effectively improve the accuracy of the identification result of whether the charging socket has a loose object.

[0112] In one embodiment of the present disclosure, the method may further include: in the process of controlling the target heating device to heat the charging socket, determining whether the charging socket has a loose object, and if the charging socket does not have a loose object, controlling the target heating device to stop heating the charging socket.

[0113] In one embodiment, determining whether the charging socket has a loose object includes: determining that the charging socket does not have a loose object if the current temperature of the charging socket is equal to or greater than a preset second temperature threshold, and determining that the charging socket has a loose object if the current temperature of the charging socket is less than the second temperature threshold.

[0114] The second temperature threshold in this embodiment may be preset according to application scenarios or specific requirements, for example, the second temperature threshold may be 2 degrees Celsius.

[0115] If the current temperature of the charging socket is equal to or greater than the second temperature threshold, it indicates that the thawable object of the charging socket has thawed, so that heating of the charging socket can be stopped to avoid energy loss caused by constant heating.

[0116] In one embodiment, determining whether the charging socket has a loose object includes: when the current temperature of the charging socket is equal to or greater than a preset second temperature threshold, controlling a camera to photograph the charging socket and obtain a second image; and receiving the second image, and identifying whether the charging socket has a loose object according to the second image.

[0117] In this embodiment, the result obtained by determining whether the loose object in the charging socket has thawed only based on the temperature of the charging socket may be inaccurate. Therefore, when it is detected that the current temperature of the charging socket is higher than the preset second temperature threshold, the camera can be controlled to take a picture of the charging socket and obtain a second image, and further determine whether the loose object in the charging socket has thawed according to the second image, so that the obtained detection result of whether the charging socket has a loose object is more accurate.

[0118] In one embodiment of the present disclosure, the method may further include:

[0119] Controlling the temperature sensor to obtain a current temperature of the charging socket, and selecting a heating mode corresponding to the current temperature from a plurality of heating modes to function as a target heating mode, and controlling the target heating device to heat the charging socket includes: controlling the target heating device to heat the charging socket by using the target heating mode.

[0120] In this embodiment, the multiple heating modes and the temperature ranges corresponding to each heating mode may be preset according to application scenarios or specific requirements. For example, the temperature range corresponding to the first-level heating mode may be set as (-10, 0), the temperature range corresponding to the second-level heating mode may be set as (-20, -10), and the temperature range corresponding to the third-level heating mode may be set as (-∞, -20).

[0121] Selecting a heating mode corresponding to the current temperature to function as the target heating mode from the multiple heating modes may include: determining a temperature range of the current temperature, and using the heating mode corresponding to the temperature range of the current temperature as the target heating mode. Thus, if the current temperature is -5 degrees Celsius, the corresponding target heating mode may be determined to be a first-level heating mode. If the current temperature is -12 degrees Celsius, the corresponding target heating mode may be determined to be a second-level heating mode. If the current temperature is -28 degrees Celsius, the corresponding target heating mode may be determined to be a third-level heating mode.

[0122] In an embodiment in which the target heating device is a heating component, multiple heating components may be disposed in the vehicle. Using a target heating mode, controlling the target heating device to heat the charging socket may be controlling a number of heating components corresponding to the target heating mode to start heating the charging socket. Specifically, the number of heating components to be started corresponding to each heating mode may be preset according to an application scenario or specific requirements.

[0123] For example, the number of heating components to be started corresponding to the first level heating mode may be set to 1, the number of heating components to be started corresponding to the second level heating mode may be set to 2, and the number of heating components to be started corresponding to the third level heating mode may be set to 3. Thus, when the target heating mode is the first level heating mode, one heating component may be controlled to start heating the charging socket. When the target heating mode is the second level heating mode, two heating components may be controlled to start heating the charging socket. When the target heating mode is the third level heating mode, three heating components may be controlled to start heating the charging socket.

[0124] In an embodiment in which the target heating device is a heat conduction component, multiple heat conduction components may be disposed in the vehicle. Controlling the target heating device to heat the charging socket using a target heating mode may involve controlling a number of heat conduction components corresponding to the target heating mode to connect to the DC charging conductor and heat the charging socket. Specifically, the number of heat conduction components corresponding to each heating mode and connected to the DC charging conductor may be preset according to an application scenario or specific requirements.

[0125] For example, the number of heat conduction components connected to the DC charging conductor may be set to one corresponding to a first level heating mode, two corresponding to a second level heating mode, and three corresponding to a third level heating mode. Thus, when the target heating mode is the first level heating mode, one heat conduction component may be controlled to connect to the DC charging conductor to heat the charging socket. When the target heating mode is the second level heating mode, two heat conduction components may be controlled to connect to the DC charging conductor to heat the charging socket. When the target heating mode is the third level heating mode, three heat conduction components may be controlled to connect to the DC charging conductor to heat the charging socket.

[0126] In one embodiment of the present disclosure, the method may further include: controlling the heating component to heat the charging socket in response to a heating command when the vehicle is fully charged or when the vehicle is not charging.

[0127] In this embodiment, when the vehicle is fully charged, the vehicle is in a sleep state and the charging connector may be frozen and unable to be removed. When the vehicle is not charging, the charging port cover may be frozen and unable to be opened. In this case, the user can trigger a heating command by clicking a one-click heating button on the vehicle or a terminal device configured to control the vehicle. In response to the heating command, the vehicle can control a heating device to heat the charging socket.

[0128] Specifically, the vehicle may control the heating device to heat both the AC charging socket and the DC charging socket in response to a heating command.

[0129] Furthermore, when a user clicks the one-click heating button on the vehicle or terminal device, the vehicle or terminal can provide the user with an AC charging socket option and a DC charging socket option for selection. If the user selects the AC charging socket option, the vehicle can control a heating device to heat the AC charging socket. If the user selects the DC charging socket option, the vehicle can control a heating device to heat the DC charging socket.

[0130] In one embodiment, when a vehicle is fully charged, if a user clicks a one-click heating button on the vehicle or a terminal device configured to control the vehicle, the vehicle can detect whether the charging socket to which the charging connector is connected is an AC charging socket or a DC charging socket. If it is detected that the charging socket to which the charging connector is connected is an AC charging socket, the heating device can be controlled to heat the AC charging socket. If it is detected that the charging socket to which the charging connector is connected is a DC charging socket, the heating device can be controlled to heat the DC charging socket.

[0131] In this embodiment, the charging socket may be heated when the vehicle is fully charged or when the vehicle is not charging, such that any loose objects attached to the charging socket or charging port cover are thawed.

[0132] In one embodiment of the present disclosure, the method may further include: in response to the heating command, detecting whether a current temperature of the charging socket is less than or equal to a preset third temperature threshold, and controlling the heating component to heat the charging socket if the current temperature is less than or equal to the third temperature threshold, or skipping controlling the heating component to heat the charging socket if the current temperature is greater than the third temperature threshold.

[0133] If the current temperature is higher than the third temperature threshold, the charging socket or charging port cover does not have any loose objects and the charging socket does not need to be heated.
