Description

Technical Field

[0001] This application relates to the technical fields of electric vehicles and electric vehicle charging, and in particular to a vehicle charging system, method, charging device, electronic device, and storage medium. Background Technology

[0002] In related technologies, charging piles for electric vehicles typically can only charge one vehicle at a time, resulting in low utilization rates. Electric vehicle charging stations require the installation of multiple charging piles to meet user demand, leading to high construction costs. Summary of the Invention

[0003] Therefore, the purpose of this application is to provide a vehicle charging system, method, charging device, electronic device, storage medium, and computer program product. This vehicle charging system enables the simultaneous charging of multiple vehicles through a charging gun equipped with a charging plug and an adapter plug, thereby improving the utilization rate of charging piles and reducing the construction cost of charging stations.

[0004] This application provides a vehicle charging system, the system comprising: a charging device configured to charge multiple vehicles to be charged; and multiple charging guns, at least one of which is provided with a charging plug and an adapter plug. The charging plug is configured to connect to the charging port of the vehicle to be charged, and the adapter plug is configured to connect to the adapter port of an adjacent vehicle or an adjacent charging gun of the vehicle to be charged, so as to indirectly connect to the charging device. The adapter port is provided on the vehicle to be charged and is used to transfer the electrical energy received by the vehicle to be charged to a terminal connected to the adapter port.

[0005] For example, when the adapter plug is configured to connect to the adapter port of an adjacent vehicle of the vehicle to be charged, the adjacent vehicle includes an adapter circuit, one end of which is connected to the charging gun through the charging port of the adjacent vehicle, and the other end of which is connected to the adapter port of the adjacent vehicle.

[0006] For example, when the adapter plug is configured to connect to an adjacent charging gun, the adjacent charging gun includes an adapter socket, the charging plug, and the adapter plug. The charging plug is used to connect to the charging port of the adjacent vehicle, the adapter socket is used to connect to the adapter plug of the charging gun, and the adjacent charging gun includes an adapter circuit. One end of the adapter circuit is connected to the charging port or charging gun of the vehicle through the adapter plug of the adjacent charging gun, and the other end of the adapter circuit is connected to the charging gun through the adapter socket of the adjacent charging gun.

[0007] For example, the charging circuit includes a charging switch, and the charging plug includes a charging switch. Each charging switch corresponds to a vehicle to be charged. For a vehicle directly connected to the charging device, when the charging switch corresponding to the vehicle is closed, the charging device charges the vehicle directly connected to the charging device. For a vehicle indirectly connected to the charging device, when both the charging switch and the charging switch corresponding to the vehicle are closed, the charging device charges the vehicle indirectly connected to the charging device.

[0008] For example, the charging device includes a control module configured to acquire vehicle information based on the plurality of charging guns and to control the charging of the plurality of vehicles to be charged based on the vehicle information.

[0009] For example, the vehicle information includes the total charging power of the charging vehicle, and the control module is further configured to: determine whether the total charging power of the charging vehicle is less than the output power of the charging device; if the total charging power of the charging vehicle is less than the output power of the charging device, control the charging switch of the charging vehicle to close and the charging switch of the next vehicle to be charged to close, so as to charge the next vehicle to be charged.

[0010] For example, the control module is further configured to: when the total charging power of the vehicles being charged is equal to the output power of the charging device, control the charging switch of the last vehicle being charged to remain in the off state, and return to the step of determining whether the charging power of the vehicles being charged is less than the output power of the charging device.

[0011] For example, the vehicle information also includes the required power of the vehicle to be charged, and the control module is further configured to: determine the required power of the next vehicle to be charged when the charging switch of the vehicle being charged is closed; if the remaining power is greater than or equal to the required power of the next vehicle to be charged, charge the next vehicle to be charged according to the required power; otherwise, charge the next vehicle to be charged according to the remaining power; wherein the remaining power is the difference between the output power of the charging device and the total charging power of the vehicle being charged.

[0012] For example, the vehicle information also includes the number of vehicles to be charged, and the control module is further configured to: determine the priority order of the vehicles to be charged when the number of vehicles to be charged is greater than or equal to 2; and allocate the charging power of the plurality of vehicles to be charged based on the priority order.

[0013] For example, the priority order is determined according to the connection order between the vehicle to be charged and the charging device. The control module is further configured to: allocate the required power of the vehicle to be charged with higher priority according to the priority order; if the remaining power is greater than or equal to the required power of the vehicle to be charged with lower priority, charge the vehicle to be charged with lower priority according to the required power; otherwise, charge the vehicle to be charged with lower priority according to the remaining power; wherein the remaining power is the difference between the output power of the charging device and the total charging power of the vehicle being charged.

[0014] For example, the control module is further configured to: after detecting that the vehicle being charged is fully charged, control the charging switch corresponding to the vehicle being charged to disconnect.

[0015] Another embodiment of this application provides a method for charging a vehicle, which is applied to the vehicle charging system of the above embodiments, specifically to a charging device. The charging device is connected to multiple vehicles to be charged via multiple charging guns. At least one of the multiple charging guns is provided with a charging plug and an adapter plug. The charging plug is configured to connect to the charging port of the vehicle to be charged, and the adapter plug is configured to connect to the adapter port of an adjacent vehicle or an adjacent charging gun of the vehicle to be charged, so as to indirectly connect to the charging device. The method includes: obtaining vehicle information based on the charging connection device; and performing charging control on the multiple vehicles to be charged based on the vehicle information.

[0016] For example, the vehicle to be charged includes a charging converter circuit and / or the charging gun includes a charging converter circuit, the charging converter circuit includes a charging switch, the charging plug includes a charging switch, and the vehicle information includes the total charging power of the vehicle being charged. The method further includes: determining whether the total charging power of the vehicle being charged is less than the output power of the charging device; if the total charging power of the vehicle being charged is less than the output power of the charging device, controlling the charging converter switch of the vehicle being charged to close and the charging switch of the next vehicle to be charged to close, so as to charge the next vehicle to be charged.

[0017] For example, the method further includes: when the total charging power of the vehicles being charged is equal to the output power of the charging device, controlling the charging switch of the last vehicle being charged to remain in the off state, and returning to the step of determining whether the charging power of the vehicles being charged is less than the output power of the charging device.

[0018] For example, the method further includes: when the charging switch of the vehicle being charged is closed, determining the required power of the next vehicle to be charged; if the remaining power is greater than or equal to the required power of the next vehicle to be charged, charging the next vehicle to be charged according to the required power; otherwise, charging the next vehicle to be charged according to the remaining power; wherein the remaining power is the difference between the output power of the charging device and the total charging power of the vehicle being charged.

[0023] In the above embodiment, the vehicle charging system includes: a charging device configured to charge multiple vehicles; and multiple charging guns, at least one of which is equipped with a charging plug and an adapter plug.

[0034] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0035] In related technologies, charging piles for electric vehicles typically can only charge one vehicle at a time, resulting in low utilization rates. Electric vehicle charging stations require the installation of multiple charging piles to meet user demand, leading to high construction costs.

[0036] In some examples, movable battery charging devices can be installed on a track. When charging multiple parked vehicles, the charging device moves to the location of the vehicle needing charging based on the charging order or distance. The charging interface automatically engages with the vehicle's charging port, sequentially charging the batteries of multiple vehicles that have been parked for an extended period. For example, ... Figure 1As shown, the convoy 10 includes multiple vehicles 18, and the charging facility 14 can charge the multiple vehicles 18. The charging facility 14 includes a system of mobile battery charging devices 22 and tracks 62, which can define the path of the mobile battery charging devices 22 from a starting point to an end point. The mobile battery charging devices 22 include a drive system 82 configured to move the mobile battery charging devices 22 along the convoy 10 to charge each vehicle 18 parked within the charging facility 14. A parking indicator 66 can indicate to the operator where the vehicle 18 should be parked. Each vehicle 18 includes an engine system 26, a battery system 30, a vehicle controller 34, a position sensor 38, a battery sensor 42, a vehicle subsystem 46, and operator input / output (I / O) devices 50.

[0037] like Figure 2 An exemplary method 400 for charging a fleet 10 using a mobile battery charging device 22 is shown. An operator drives one of the vehicles 18 from the fleet 10 into the charging facility 14 and parks the vehicle 18 near one of the parking indicators 66. A positioning circuit 114 receives information indicating the position of the vehicle 18 relative to the parking indicator 66. In response to determining that the position of the vehicle 18 relative to the parking indicator 66 is acceptable, the positioning circuit 114 may notify the operator via an operator I / O device 50 to indicate that the position of the vehicle 18 is acceptable. In response to determining that the position of the vehicle 18 relative to the parking indicator 66 is unacceptable, the positioning circuit 114 may indicate that the position of the vehicle 18 relative to the parking indicator 66 is unacceptable. A battery state determination circuit 118 receives information indicating the state of charge (SOC) of the battery system 30 of the vehicle 18. The battery state determination circuit 118 may determine the amount of battery charge required for the vehicle 18 to complete an upcoming task. The battery state determination circuit 118 sends information indicating the state of the battery system 30 and information indicating the identity of the vehicle 18 to a mobile battery charging device controller 86.

[0038] The battery charging circuit 138 commands the drive system 82 of the mobile battery charging device 22 to follow a path until the mobile battery charging device 22 approaches the first vehicle 18 along the path. It receives information about the battery status and the identity of the vehicle 18, determines the amount of battery charge required for the upcoming task, and then determines the relative position of the charging port 58 of the vehicle 18 and the mobile battery charging device 22. It commands the drive system 82 of the mobile battery charging device 22 to substantially align the mobile battery charging device 22 with the charging port 58 of the vehicle 18. Then, the charging port 94 engages with the charging port 58 of the vehicle 18. The battery system 30 of the vehicle 18 is charged based on the SOC of the battery system 30 and / or the charging requirements for completing the upcoming task. The battery status determination circuit 118 determines that the battery system 30 is fully charged and sends a notification to the battery charging circuit 138. It commands the charging interface drive system 98 to disengage the charging port 94 of the charging interface 74 from the charging port 58 of the vehicle 18 and then proceed along the path to approach the next vehicle 18.

[0039] However, this type of battery charging device can only charge one vehicle at a time, and it requires a track to be laid for the battery charging device. The battery charging device has an automated plug-and-play charging interface, and the installation cost and equipment cost are relatively high.

[0040] Based on this, this application proposes a vehicle charging system, which includes a charging gun with a charging plug and an adapter plug. This charging gun enables multiple vehicles to be charged simultaneously, and multiple vehicles can share a single charging device, thereby improving the utilization rate of charging piles and reducing the construction cost of charging stations.

[0041] Figure 3 This is a schematic diagram of a vehicle charging system 300 according to an embodiment of this application.

[0042] like Figure 3 As shown, the vehicle charging system 300 includes: a charging device 301 configured to charge a plurality of vehicles 304 to be charged; a plurality of charging guns 303, at least one of which is provided with a charging plug and an adapter plug, the charging plug being configured to connect to the charging port of the vehicle to be charged, and the adapter plug being configured to connect to the adapter port of an adjacent vehicle or an adjacent charging gun of the vehicle to be charged, so as to be indirectly connected to the charging device.

[0043] The charging port is located on the vehicle to be charged and is used to transfer the electrical energy received by the vehicle to the terminal connected to the charging port.

[0044] Exemplarily, the vehicle charging system 300 includes: a charging device 301, multiple charging guns 303, and multiple vehicles 304. The charging device 301 is used to charge multiple vehicles 304. The charging device can be a charging pile or other form of charging power source; this application uses a charging pile as an example. The multiple charging guns 303 are used to connect vehicles 304 to each other, and / or to connect vehicles 304 to the charging device 301. At least one of the multiple charging guns 303 is provided with a charging plug and an adapter plug. It is understood that the charging plug connects to the charging port of the vehicle to be charged for charging the vehicle. The adapter plug connects to the adapter port of an adjacent vehicle or an adjacent charging gun for indirect connection to the charging device. It should be noted that "adjacent" as described above does not necessarily mean physically adjacent; any location to which a charging gun can be connected can be considered adjacent. For example, in a certain scenario, charging device 301 is charging vehicles 1, 2, and 3. A new vehicle 4 is added. The adapter plug of the charging gun connected to vehicle 4 can connect to the charging port of vehicle 1, or it can connect to the charging ports of vehicles 2 and 3. For instance, physically, vehicle 4 may be parked next to vehicle 3, but if the adapter plug of the charging gun connected to vehicle 4 is connected to the charging port of vehicle 1, then vehicle 1 is the adjacent vehicle of vehicle 4. Similarly, "adjacent charging gun" does not necessarily refer to physical proximity; any charging gun that can be electrically connected to this charging gun is considered an adjacent charging gun.

[0045] Of course, the adjacent vehicle is not the same vehicle as the one in "the charging plug is configured to connect to the charging port of the vehicle to be charged", and the adjacent charging gun is not the same charging gun as "at least one of the multiple charging guns is equipped with a charging plug and an adapter plug".

[0046] It should be noted that this application refers to the installation of a charging port on the vehicle. The charging port of the vehicle can be understood as an energy transfer interface, through which the electrical energy received by the vehicle can be transferred to the device terminal connected to the charging port.

[0047] The vehicle charging system of this application enables simultaneous charging of multiple vehicles using a charging gun equipped with a charging plug and an adapter plug, thereby improving the utilization rate of charging piles and reducing the construction cost of charging stations. It can automatically charge multiple vehicles using a single charging pile for a longer period (i.e., without user intervention), making it suitable for scenarios where electric vehicles are parked and charging for extended periods, such as overnight at home or daytime charging at the workplace, thus improving the utilization efficiency of charging piles.

[0048] As an example, at least one of the multiple charging guns is directly connected to the charging device 301. To better distinguish between charging guns that are directly connected to the charging device 301 and charging guns that are indirectly connected to the charging device 301, the charging guns that are directly connected to the charging device 301 will be referred to as direct charging guns, and the charging guns that are indirectly connected to the charging device 301 will be referred to as transfer charging guns.

[0049] For example, the multiple charging guns include at least one adapter charging gun and at least one direct charging gun. One end of the direct charging gun is directly connected to the charging device 301, and the other end of the direct charging gun includes a first charging plug (hereinafter referred to as the first charging plug). The first charging plug is connected to the charging port of the vehicle 304 to be charged, so as to directly supply power to the vehicle 304 through the direct charging gun. The adapter charging gun includes an adapter plug and a second charging plug (hereinafter referred to as the second charging plug). It can be understood that the two ends of the adapter charging gun are the adapter plug and the second charging plug, respectively. The second charging plug has the same function as the first charging plug, both of which are connected to the charging port of the vehicle 304 to be charged. The adapter plug can be connected to the charging port of the adjacent vehicle 4 (in which case the vehicle must have a charging port), or to the second charging plug of an adjacent adapter charging gun to achieve cascading between adapter charging guns, or to the first charging plug of a direct charging gun to achieve connection between adapter charging guns and direct charging guns. It can be understood that the adapter charging gun is for indirect connection with the charging device 301. In this way, the charging device 301 can charge multiple vehicles 302 simultaneously through the adapter charging gun.

[0050] The vehicle charging system of this application enables the simultaneous charging of multiple vehicles through a converter charging gun, thereby improving the utilization rate of charging piles and reducing the construction cost of charging stations.

[0051] The following provides a detailed explanation of the connection method for the adapter charging gun.

[0052] like Figure 4 The example diagram of the charging gun connection method shown illustrates that when the charging plug is configured to connect to the charging port of an adjacent vehicle of the vehicle to be charged, the adjacent vehicle 304 includes a charging circuit. One end of the charging circuit is connected to the charging gun 303 through the charging port of the adjacent vehicle 304, and the other end of the charging circuit is connected to the charging port of the adjacent vehicle 304.

[0053] For example, such as Figure 4As shown, the charging system includes a charging pile 301, charging vehicles 304, a direct charging gun 101, and a converter charging gun 102. The charging pile 301 provides the charging current. When multiple vehicles are ready to charge, the direct charging gun 101 is connected to vehicle 1, and the converter charging guns 102 are connected between the charging vehicles 304. Multiple vehicles can share a single charging pile for charging. For example... Figure 4 The connection method of the charging gun shown is such that vehicle 304 includes at least a charging port 106 and a charging port 107. The charging port of vehicle 1 is used to connect the charging plug of charging gun 101, and the charging ports of vehicles 2-N are used to connect the charging plug of charging gun 102. Charging gun 101 is connected to the charging pile and has a charging plug, a charging cable, and a sampling cable. It is used for connecting the charging pile and vehicle 1, and can also be used to collect vehicle information of vehicle 1. Charging gun 102 has a charging plug, a charging cable, and a sampling cable. It is used for connecting vehicles 2-N, and can also be used to collect vehicle information of vehicles 2-N. The charging plug of charging gun 102 is connected to the charging port of vehicle 304 to realize cascading between multiple vehicles. Vehicle 304 also has a charging circuit 105. One end of the charging circuit is connected to charging gun 303 through the charging port 106 of the vehicle to be charged 304, and the other end of the charging circuit is connected to the charging port 107 of the vehicle to be charged 304. For example, for vehicle 2, one end of the charging converter circuit of vehicle 2 is connected to the charging gun 102 between vehicle 1 and vehicle 2 through the charging port of vehicle 2, and the other end of the charging converter circuit of vehicle 2 is connected to the charging port 107 of vehicle 2. It can be understood that the charging converter circuit is the control circuit that smoothly transmits the power of the charging device to the next vehicle 304.

[0054] For example, when charging a vehicle, the direct charging gun 101 connects the charging pile 301 to a vehicle to be charged, and the transfer charging gun 102 connects different vehicles to be charged in sequence, with each transfer charging gun 102 connected in series. Figure 4 When vehicle 2 is being charged, the charging adapter 102 must first be connected to both vehicle 1 and vehicle 2. The charging device can connect to any number of charging adapters 102, meaning it can connect to any number of electric vehicles, which are connected in series. Preferably, the peak number of electric vehicles is determined by the number of available parking spaces.

[0055] like Figure 5 The diagram shows an example of another connection method for the adapter charging gun. When the adapter plug is configured to connect to an adjacent charging gun, the adjacent charging gun includes an adapter socket, a charging plug, and an adapter plug. The charging plug is used to connect to the charging port of the adjacent vehicle, and the adapter socket is used to connect to the adapter plug of the charging gun. The adjacent charging gun includes an adapter charging circuit. One end of the adapter charging circuit is connected to the charging port of the vehicle or the charging gun through the adapter plug of the adjacent charging gun, and the other end of the adapter charging circuit is connected to the charging gun through the adapter socket of the adjacent charging gun.

[0056] It should be noted that the "adjacent" mentioned above does not necessarily mean physically adjacent; any location that the charging gun can connect to can be considered adjacent. For example, ... Figure 5 As shown, for the charging gun between vehicle 2 and vehicle 3, its adjacent charging gun is the charging gun between vehicle 1 and vehicle 2. The adjacent charging gun (the charging gun between vehicle 1 and vehicle 2) includes an adapter socket, a charging plug, and an adapter plug. The charging plug is used to connect to the charging port of the adjacent vehicle (vehicle 2), and the adapter socket is used to connect to the adapter plug of the charging gun. That is, the charging plug of the charging gun between vehicle 2 and vehicle 3 is connected to the adapter socket of the charging gun between vehicle 1 and vehicle 2. The function of the adapter plug of the charging gun between vehicle 1 and vehicle 2 is similar to the connection method of the adapter plug of the charging gun between vehicle 2 and vehicle 3.

[0057] For example, such as Figure 5 As shown, the charging system includes a charging pile 301, a charging vehicle 304, and charging guns (specifically, a direct charging gun 101 and a converter charging gun 102). When multiple vehicles are ready to charge, the direct charging gun 101 is connected to vehicle 1, and one end of the converter charging gun is connected to the charging port 106 of vehicle 304, while the other end is connected to the charging plug of the previous charging connection device 303. The converter charging gun 102 has a converter plug and a charging plug at both ends. The converter charging gun also has a converter socket, which can be integrated with the charging plug, or it can be set as a separate component on the charging gun. Figure 5 The example shown integrates the adapter socket and the charging plug. The following is an example of integrating the adapter socket and the charging plug.

[0058] For example, for the adapter charging gun 102 between vehicle 1 and vehicle 2, the adapter port of the adapter charging gun 102 can be connected to the adapter socket of the direct charging gun 101. The charging plug has an adapter socket and a charging port. The adapter socket of the adapter charging gun 102 can be connected to another adapter charging gun 102 (e.g., the adapter charging gun 102 connecting vehicle 2 and vehicle 3), and the charging port can be connected to vehicle 2. It should be noted that the adapter sockets of the direct charging gun 101 and the adapter charging gun 102 can be equipped with end caps, which are kept closed when not in use, to ensure the safety of the adapter sockets of the direct charging gun 101 and the adapter charging gun 102.

[0059] For example Figure 5 The connection method of the charging gun shown indicates that vehicle 304 includes at least a charging port 106, but may not have an adapter port 107, and vehicle 304 may or may not have an adapter circuit 105. Figure 5In the connection method of the charging gun shown, the charging circuit 105 is located outside the electric vehicle, for example, it can be a circuit in the charging plug of the charging gun. One end of the charging circuit 105 is connected to other charging guns 303 through the charging plug of the charging gun 102, and the other end of the charging circuit is connected to the adjacent charging gun 102 through the charging socket of the charging gun 102. It should be noted that the charging gun 101 connected to the charging pile can also have a charging plug and a charging socket. The charging plug is connected to the first vehicle to charge it, and the charging socket can be connected to the charging gun 102.

[0060] For example, the connection method of the adapter charging gun can also be combined with Figure 4 The method shown and Figure 5 As shown, for example, vehicles equipped with a charging adapter circuit and charging port can use... Figure 4 Connect the charger as shown in the diagram. Vehicles without a charging adapter circuit and charging port can use this method. Figure 5 Connect to the adapter charging gun shown, which has an adapter charging circuit. Of course, vehicles with adapter charging circuits and adapter ports can also use it. Figure 5 The charging gun with the charging converter circuit shown is connected, meaning that the charging converter function is used instead of the vehicle's charging function.

[0061] It should be noted that the number of adapter sockets in the charging gun can be 1 (e.g., Figure 5 The connection can be between vehicles (as shown in the diagram), or multiple vehicles can be connected. For example, the charging gun 101 has N charging sockets. The charging port 106 of vehicle 1 is connected to the charging gun 101, and the charging ports 106 of vehicles 2-5 are connected to the charging plugs of their respective charging guns 102. The charging plugs of these three charging guns are all plugged into the charging sockets of the charging gun 101, thus enabling vehicles 2-5 to be connected in parallel. Of course, if the charging ports of a vehicle support the connection of multiple charging guns, parallel connection between multiple vehicles can also be achieved. Alternatively, the charging gun can be configured with multiple ports, allowing parallel connection between multiple vehicles as well.

[0062] As an example, the charging circuit includes a charging switch, and the charging plug includes a charging switch. Each charging switch corresponds to a vehicle to be charged. For vehicles directly connected to the charging device, the charging device charges the vehicle when the charging switch corresponding to the vehicle is closed. For vehicles indirectly connected to the charging device, the charging device charges the vehicle when both the charging switch and the charging switch corresponding to the vehicle are closed.

[0063] For example, such as Figure 6The schematic diagram of the charging system shown indicates that battery pack 1 is the battery pack for vehicle 1, battery pack 2 is the battery pack for vehicle 2, battery pack 3 is the battery pack for vehicle 3, and battery pack N is the battery pack for vehicle N. The charging circuit of each battery pack includes a charging switch 103, and the transfer charging circuit 105 includes a transfer charging switch 104. Each charging switch corresponds to a vehicle to be charged, with one charging switch on each charging branch corresponding to each battery pack. For vehicles directly connected to the charging device (the vehicle corresponding to battery pack 1), when the charging switch corresponding to vehicle 304 is closed, the charging device charges the vehicle. That is, when the charging switch is closed, the charging device is connected to vehicle 304, and the charging device charges the vehicle (the vehicle corresponding to battery pack 1). For vehicles indirectly connected to the charging device (e.g., the vehicles corresponding to battery packs 2-N), when both the charging switch and the transfer charging switch corresponding to the vehicle are closed, the charging device charges the vehicle indirectly connected to the charging device.

[0064] It should be noted that, for Figure 6 The series connection between vehicles shown requires that charging of vehicle 304 can only be performed when the charging switches of the upstream vehicle and the corresponding charging switches of this vehicle are both closed. For example, for the vehicle corresponding to battery pack 3, charging can only be performed when the charging switches of battery pack 3 and battery pack 2 are all closed. Preferably, the vehicles can be connected in parallel. In this way, for the vehicle to be charged that is indirectly connected to the charging device, the charging device can charge the vehicle only when the corresponding charging switches and charging switches of this vehicle are closed. Of course, the vehicles can also be connected in both series and parallel modes. In this case, the circuit connection may be more complex. For this vehicle, as long as there is a circuit connection with the charging device, electrical energy can be transferred to charge this vehicle.

[0065] As an example, the charging device includes a control module configured to acquire vehicle information based on multiple charging guns and to control the charging of multiple vehicles to be charged based on the vehicle information.

[0066] For example, the charging circuit may also include a data acquisition line for collecting vehicle information. The charging control module of the charging device 301 can collect the charging parameters of all vehicles through the data acquisition line, and control how the electric vehicles are charged based on the vehicle charging parameters. For example, when only the first vehicle is being charged, the charging switch of the first vehicle is closed, and the charging control module controls the charging switch 104 of the charging circuit 105 to remain open. When the second vehicle is ready to be charged, the charging control module controls the charging switch 104 of the charging circuit 105 of the first vehicle to close, and the charging switch of the second vehicle to close, connecting the circuit to charge the second vehicle.

[0067] The following provides a detailed explanation of the control method of the charging device when the vehicle is charging.

[0068] As an example, the vehicle information includes the total charging power of the vehicle being charged. The control module is also used to: determine whether the total charging power of the vehicle being charged is less than the output power of the charging device; if the total charging power of the vehicle being charged is less than the output power of the charging device, control the charging switch of the vehicle being charged to close and the charging switch of the next vehicle to be charged to close, so as to charge the next vehicle to be charged.

[0069] For example, vehicle information can be collected through a charging connection device, including the total charging power of the vehicles being charged. In this application, vehicles waiting to be charged are collectively referred to as vehicles awaiting charging, and vehicles currently being charged are collectively referred to as vehicles being charged. The control module of the charging device continuously determines whether the total charging power of the vehicles being charged is less than the output power of the charging device. It can be understood that the total charging power of the vehicles being charged is the power used by multiple vehicles being charged or the total power used by a single vehicle. The charging power of the electric vehicle changes with the battery charge level. For example, when the battery charge level is low, the charging power will be increased to fully charge it as quickly as possible; conversely, when the charge level is high or close to full, the charging power will be reduced to prevent overcharging and damage to the battery. Therefore, the total charging power of the vehicles being charged is constantly changing. The output power of the charging device can be the output power of the charging pile. If the charging pile is at its rated power, the output power of the charging device remains unchanged; if the charging pile is not at its rated power, the output power of the charging device will also change.

[0070] For example, when the total charging power of the vehicles being charged is less than the output power of the charging device, it indicates that the charging device still has residual power. The system then controls the switching on the vehicle being charged to close and the charging switch for the next vehicle to be charged to close, so that the next vehicle can be charged. For instance, when charging vehicle 1, if the charging power of vehicle 1 is less than the power of the charging pile, it indicates that the charging pile has residual power. The switching on vehicle 1 to close is then closed, and the next vehicle to be charged begins charging.

[0071] It should be noted that, from the perspective of energy conservation, the total charging power of a vehicle is always less than or equal to the output power of the charging device. However, if energy losses during transmission are considered, the total charging power of the vehicle may always be less than the output power of the charging device. Therefore, the condition for determining whether there is remaining power can also be set as whether the total charging power of the vehicle is less than a certain percentage of the output power of the charging device. For example, if the total charging power of the vehicle is less than 95% of the output power of the charging device, it indicates that the charging device still has remaining power. This percentage can also be a range, which can be obtained based on actual experimental procedures or experience.

[0072] As an example, the control module is also used to: keep the charging switch of the last vehicle in the charging process off when the total charging power of the vehicles in the charging process is equal to the output power of the charging device, and return to the step of determining whether the charging power of the vehicles in the charging process is less than the output power of the charging device.

[0073] For example, if the total charging power of the vehicles being charged equals the output power of the charging device, it means the charging device has no remaining power, i.e., no power to allocate to the next vehicle waiting to be charged. In this case, the charging switch of the last vehicle being charged is kept off. However, the total charging power of the vehicles being charged changes in real time. The process returns to the step of determining whether the charging power of the vehicles being charged is less than the output power of the charging device. If the total charging power of the vehicles being charged is less than the output power of the charging device, the charging switch of the vehicles being charged and the charging switch of the next vehicle waiting to be charged are then closed. For example, if vehicles 1-5 are vehicles being charged, and the total charging power of vehicles 1-5 equals the output power of the charging device, then the charging device has no remaining power to provide to the next vehicle waiting to be charged. But as time changes, vehicle 1 gradually charges, and the charging power of vehicle 1 decreases. The total charging power of vehicles 1-5 also decreases, and the total charging power of vehicles 1-5 becomes less than the output power of the charging device. At this time, the charging switch of vehicle 5 and the charging switch of vehicle 6 can be closed to charge vehicle 6. The same principle applies to subsequent vehicles. In summary, when the sum of the charging power of the charging vehicles is less than the power of the charging pile, the charging switch 104 of the last charging vehicle is turned on to start charging, until the last vehicle waiting to be charged.

[0074] It should be noted that, similarly to the above, if energy losses during transmission are considered, the total charging power of the vehicle may always be less than the output power of the charging device. Therefore, the condition for determining whether there is no remaining power can also be set as whether the total charging power of the vehicle is equal to a certain percentage of the output power of the charging device. For example, if the total charging power of the vehicle is equal to 95% of the output power of the charging device, it indicates that the charging device has no remaining power. This percentage can also be a range, which can be obtained based on actual experimental procedures or experience.

[0075] The charging power allocation method of this application can charge multiple vehicles simultaneously, making full use of the charging power of the charging pile, maximizing the charging efficiency of the charging pile, and saving users charging time.

[0076] As an example, the control module is also used to: determine the required power of the next vehicle to be charged when the charging switch of the vehicle being charged is closed; if the remaining power is greater than or equal to the required power of the next vehicle to be charged, charge the next vehicle to be charged according to the required power; otherwise, charge the next vehicle to be charged according to the remaining power; wherein the remaining power is the difference between the output power of the charging device and the total charging power of the vehicle being charged.

[0077] For example, such as Figure 7 The flowchart illustrating the charging power allocation method shows that when the charging switch of a vehicle currently being charged is closed, the control module calculates the power required by the next vehicle to be charged. If the difference between the output power of the charging device and the total charging power of the vehicles currently being charged is greater than the power required by the next vehicle, then the next vehicle will begin charging at the required power. Otherwise, it will begin charging at the remaining power of the charging device. For example, if the total charging power of vehicles 1 and 2 is less than the power of the charging pile, the charging switch 104 of vehicle 2 will open, and vehicle 3 will begin charging. However, if the power required by vehicle 3 is greater than the remaining power of the charging device, meaning the remaining power of the charging device cannot meet the needs of vehicle 3, it will only charge vehicle 3 according to the remaining power of the charging device. Of course, if the charging power of vehicles 1 and 2 decreases subsequently, the charging power of vehicle 3 can be increased to meet its charging needs. If the charging equipment still has remaining power after meeting the charging needs of all vehicles currently being charged, then it will charge the next vehicle to be charged.

[0078] As an example, the vehicle information also includes the number of vehicles waiting to be charged. The control module is also used to: determine the priority order of the vehicles waiting to be charged when the number of vehicles waiting to be charged is greater than or equal to 2; and allocate the charging power of multiple vehicles waiting to be charged based on the priority order.

[0079] For example, the control module also collects the number of vehicles waiting to be charged based on the charging connection device. When the number of vehicles waiting to be charged is greater than or equal to two, i.e., multiple vehicles are being charged, the priority order of the vehicles waiting to be charged can be determined, and the charging power of the multiple vehicles waiting to be charged can be allocated based on the priority order. The priority order can be the order in which electric vehicles are connected, the order set by the user according to actual needs, etc. For example, the priority order of vehicles that are connected earlier is higher than that of vehicles that are connected later.

[0080] Of course, connected electric vehicles can be charged simultaneously, charged in a specific order, or some electric vehicles can be charged simultaneously while the remaining electric vehicles are charged in sequence.

[0081] As an example, the priority order is determined based on the connection order between the vehicle to be charged and the charging device. The control module is also used to: allocate the required power of the vehicle to be charged with higher priority based on the priority order; if the remaining power is greater than or equal to the required power of the vehicle to be charged with lower priority, charge the vehicle to be charged with lower priority according to the required power; otherwise, charge the vehicle to be charged with lower priority according to the remaining power; wherein, the remaining power is the difference between the output power of the charging device and the total charging power of the vehicle being charged.

[0082] For example, the charging device can distribute power to electric vehicles charging simultaneously by sharing the voltage equally among all charging vehicles, meeting the power requirements of electric vehicles sequentially according to the charging order, and allocating the remaining power of the charging pile to vehicles that do not meet their required power needs. When multiple vehicles are charging simultaneously, the control module can meet the power requirements of higher-priority vehicles first, and then distribute the remaining power accordingly.

[0083] The charging control module of the charging device in this application continuously collects the charging power of the vehicles being charged, calculates the remaining charging power of the charging pile in real time, and redistributes the remaining charging power of the corresponding charging guns according to the priority order of redistribution charging power allocation to charge the next vehicle waiting to be charged. This ensures that each charging gun or transfer charging gun meets the power and current requirements of the electric vehicle's BMS as much as possible, thereby maximizing the charging efficiency of the charging pile and saving users' charging time.

[0084] As an example, the control module is also used to: control the charging switch corresponding to the charging vehicle to turn off after detecting that the vehicle is fully charged.

[0085] For example, the charging device's control module detects that a vehicle is fully charged and then disconnects the charging switch for that vehicle. Of course, if other vehicles connect to the charging circuit during the charging process, a loop is entered to determine whether the total charging power of the vehicles is less than the output power of the charging device. The charging device terminates its operation after all vehicles are fully charged.

[0086] For example, the vehicle's charging switch can be controlled to open by the charging device's control module or by the vehicle's BMS (Battery Management System). For instance, if the charging device's control module detects that the vehicle is fully charged, it can send a low-voltage signal to the vehicle's BMS, which then controls the charging switch to open. Alternatively, a charging switch can be located at the charging plug, where the charging device's control module can directly control the charging switch at the charging plug to open upon detecting that the vehicle is fully charged.

[0087] Figure 8 This is a flowchart of a vehicle charging method according to an embodiment of this application.

[0088] like Figure 8 As shown, the charging pile collects data from vehicles waiting to be charged, including the number of vehicles and the charging power. Vehicle 1 connects to the charging pile, and the charging pile 1 prepares to charge. The charging control module of the charging pile collects the number of connected electric vehicles to determine if multiple electric vehicles are waiting to be charged. If only vehicle 1 is waiting to be charged, the charging pile 301 charges only vehicle 1 until it is fully charged. If multiple electric vehicles are waiting to be charged, the charging control module of the charging pile 301 collects the battery charging parameters of the vehicles waiting to be charged and charges vehicle 1. At the same time, the charging control module collects the charging power of vehicle 1 and determines whether the charging power of vehicle 1 is less than the power of the charging pile. If the charging power of vehicle 1 is less than the power of the charging pile, the charging pile has remaining power, the charging switch 104 for the vehicle being charged closes, and the next vehicle waiting to be charged begins charging. If the charging power of vehicle 1 is equal to the power of the charging pile, the charging pile has no remaining power, and the charging switch 104 for the last vehicle being charged remains open. The charging control module of the charging pile 301 continuously determines whether the charging power of the vehicles being charged is less than the power of the charging pile, maintaining this cycle. Once the charging control module of charging pile 301 detects that a vehicle is fully charged, it disconnects the charging switch 103 for that vehicle. If another vehicle connects to the charging transfer circuit 105 while vehicle 1 is charging alone, the same cycle repeats. The charging pile stops operating after all vehicles are fully charged.

[0089] It should be noted that the charging device communicates with the external environment. The charging station can collect data on the number of connected electric vehicles and the battery charging parameters of the electric vehicles. Preferably, the sampling lines inside the charging gun and adapter gun collect the charging power of the vehicles and transmit the signals to the charging station for billing, user viewing, etc. Preferably, the user can set a timed charging schedule.

[0090] The method provided in this application can automatically charge multiple vehicles using one charging station over a longer period of time (i.e., without active user intervention). It is suitable for electric vehicles that are parked and charging for a longer period of time, such as overnight at home or during the day at the workplace. This improves the utilization efficiency of the charging station, makes full use of the charging power of the charging station, maximizes the charging efficiency of the charging station, and saves users charging time.

[0091] This application also proposes a method for charging a vehicle.

[0092] As an example, such as Figure 9As shown, the vehicle charging method is applied to the charging control system of the above example, specifically to the charging device. The charging device is connected to multiple vehicles to be charged via multiple charging guns. At least one of the multiple charging guns is provided with a charging plug and an adapter plug. The charging plug is configured to connect to the charging port of the vehicle to be charged, and the adapter plug is configured to connect to the adapter port of an adjacent vehicle or an adjacent charging gun, so as to indirectly connect to the charging device. The method includes:

[0093] S901 obtains vehicle information based on the charging connection device.

[0094] S902 controls the charging of multiple vehicles based on vehicle information.

[0095] For example, the vehicle to be charged includes a charging circuit and / or the charging gun includes a charging circuit, the charging circuit includes a charging switch, the charging plug includes a charging switch, and the vehicle information includes the total charging power of the vehicle being charged. The vehicle charging method further includes: determining whether the total charging power of the vehicle being charged is less than the output power of the charging device; if the total charging power of the vehicle being charged is less than the output power of the charging device, controlling the charging switch of the vehicle being charged to close and the charging switch of the next vehicle to be charged to close, so as to charge the next vehicle to be charged.

[0096] For example, the method for charging a vehicle further includes: when the total charging power of the vehicles being charged is equal to the output power of the charging device, controlling the charging switch of the last vehicle being charged to remain in the off state, and returning to the step of determining whether the charging power of the vehicles being charged is less than the output power of the charging device.

[0097] For example, the method for charging a vehicle further includes: when the charging switch of the vehicle being charged is closed, determining the required power of the next vehicle to be charged; if the remaining power is greater than or equal to the required power of the next vehicle to be charged, charging the next vehicle to be charged according to the required power; otherwise, charging the next vehicle to be charged according to the remaining power; wherein the remaining power is the difference between the output power of the charging device and the total charging power of the vehicle being charged.
