[0003] With the continuous development of science and technology, batteries are increasingly used in daily production and life. At present, more and more electrical devices include two or more independent battery management systems (BMS). When charging an electrical device, the user needs to operate the power supply to connect to each BMS separately in order to charge the battery corresponding to the BMS. Therefore, for an electrical device including multiple BMSs, the user needs to operate the power supply to connect to each BMS multiple times, making the charging process cumbersome. Summary of the Invention

[0004] The embodiments of the present application provide a charging control device, method, electronic device, readable storage medium and system to solve the cumbersome operation of the current charging process.

[0005] In a first aspect, an embodiment of the present application provides a charging control device, comprising an input module, a charging switch module, and a control module. The input module is configured to connect to a charging pile, and the charging switch module is configured to connect to at least one battery. Each battery corresponds to a battery management system (BMS), and the control module is communicatively connected to each BMS and charging pile, respectively.

[0006] A control module is configured to obtain charging parameter information of at least one battery, and determine first target charging parameter information based on each charging parameter information, and determine at least one first target battery, wherein the first target battery is a battery that the BMS allows the charging pile to charge;

[0007] The control module is further configured to send first target charging parameter information to the charging pile, and control the charging circuit where each first target battery is located to be turned on, so that the charging pile charges each first target battery according to the first target charging parameter information.

[0008] In an embodiment of the present application, the charging control device includes an input module, a charging switch module and a control module. The input module is used to connect to the charging pile, and the charging switch module is used to connect to at least one battery, wherein each battery corresponds to a battery management system BMS. Based on this, multiple BMSs in the power-consuming device can be aggregated through the charging control device. Specifically, when the power-consuming device needs to be charged, the control module can communicate with each BMS separately, so that the charging parameter information of one or more batteries can be obtained, and then the first target charging parameter information can be determined in combination with each charging parameter information. Next, the control module sends the first target charging parameter information to the charging pile, so that the charging pile charges each first target battery according to the first target charging parameter information, without the need for the user to manually switch to communicate with the charging pile to connect to the BMS. At the same time, the control module controls the charging circuit where each first target battery is located to be turned on, so as to realize charging of one or more batteries separately through one charging pile, effectively simplifying the charging process.

[0009] In one embodiment of the present application, the power switch module includes N parallel branches, a first end of each branch is connected to the input module, and a second end of each branch is respectively used to connect to the battery;

[0010] Each branch includes a switch submodule;

[0011] Each switch submodule is communicatively connected to the control module and is configured to be turned on or off in response to a first control signal from the control module.

[0012] In an embodiment of the present application, the charging switch module includes N parallel branches, wherein the first end of each branch is connected to the input module, and the second end of each branch is used to connect to a battery. Based on this, after the charging pile is connected to the input module, the switch submodule included in each branch can be controlled to turn on or off, thereby charging the battery connected to the branch. In addition, among multiple parallel branches, the switch submodule in each branch can be flexibly controlled to turn on or off according to the charging needs of the battery corresponding to each branch, thereby improving the convenience of charging the electrical device.

[0013] In one embodiment of the present application, each branch further includes a battery protection module;

[0014] In each branch, each battery protection module is connected in series between the first end and the switch submodule;

[0015] Each battery protection module is unidirectionally conductive, and the current conduction direction of each battery protection module is from the first end to the second end.

[0016] In this embodiment of the present application, a battery protection module is included between the first end of each branch and the switch submodule, and the battery protection module is only turned on when the current flows from the first end to the second end. This prevents current backflow during battery charging when the battery voltage exceeds the charging station voltage. Furthermore, because multiple batteries are connected in parallel through multiple branches, the battery protection module can prevent circulating charging caused by voltage inconsistencies between different batteries.

[0017] In one embodiment of the present application, the device further includes an insulation detection module, the insulation detection module is communicatively connected to the control module, and each charging switch module is connected to the input module via a high-voltage wiring harness;

[0018] The insulation detection module is used to perform insulation detection on the high-voltage wire harness during the charging process of the first target battery to obtain a detection result and send the insulation detection result to the control module.

[0019] In an embodiment of the present application, the insulation detection module can perform insulation detection on the high-voltage wire harness in the charging control device and send the detection results to the control module, thereby improving the reliability of the charging process.

[0020] In a second aspect, an embodiment of the present application provides a charging control method, which is applied to the charging control device in the first aspect and any embodiment of the first aspect, and the method includes:

[0021] Obtain charging parameter information of M batteries, wherein the M batteries are connected to a charging control device and each battery has a one-to-one correspondence with a battery management system (BMS);

[0022] Determine first target charging parameter information according to each charging parameter information, and determine m first target batteries, wherein the first target battery is a battery that the BMS allows the charging pile to charge, 1≤m≤M;

[0023] The first target charging parameter information is sent to the charging pile, and the charging circuit where each first target battery is located in the charging control device is controlled to be turned on, so that the charging pile charges each first target battery according to the first target charging parameter information.

[0024] In an embodiment of the present application, when charging an electrical device is required, the first target charging parameter information is determined by obtaining the charging parameter information of one or more batteries and combining each charging parameter information. Next, the first target charging parameter information is sent to the charging pile so that the charging pile charges each first target battery according to the first target charging parameter information. This eliminates the need for the user to manually switch the communication connection with the charging pile to the BMS, thereby simplifying the charging operation. At the same time, the control module controls the charging circuit where each first target battery is located to be turned on, thereby enabling charging of one or more batteries separately through one charging pile, effectively simplifying the charging process.

[0025] In one embodiment of the present application, each charging parameter information includes a first charging current of each battery, and the first target charging parameter information includes a first target charging current;

[0026] Determining first target charging parameter information according to each charging parameter information includes:

[0027] determining a first number of first target batteries and a first charging current for each first target battery;

[0028] A first target charging current is determined according to a minimum charging current among the first charging currents and a first number of first target batteries.

[0029] In the embodiment of the present application, a first target charging current is determined by determining a first number m of first target batteries and a minimum charging current among the m first charging currents. Based on the minimum charging current among the first charging currents and the first number of first target batteries, a first target charging current is determined. Based on this, when the charging pile outputs a charging current based on the first target current, the problem of potential battery overcurrent can be resolved, thereby improving the reliability of the charging process and facilitating the improvement of battery life.

[0030] In one embodiment of the present application, before obtaining the charging parameter information of the M batteries, the method further includes:

[0031] In response to establishing a connection with the charging pile, charging request information is sent to M BMSs respectively, so that each BMS feeds back charging parameter information of the battery.

[0032] In an embodiment of the present application, after establishing a connection with the charging pile, charging request information is sent to M BMSs, without the need for the user to manually switch the communication connection with the charging pile to the BMS, thereby achieving communication between the charging pile and multiple BMSs.

[0033] In one embodiment of the present application, after sending the first target charging parameter information to the charging pile and controlling the charging circuit where each first target battery in the charging control device is located to be turned on, the method further includes:

[0034] Receiving charging completion information of n second target batteries, wherein the second target batteries are batteries that have been fully charged among the m first target batteries, 1≤n≤m;

[0035] In response to the charging completion information of the n second target batteries, sending second target charging parameter information to the charging pile, so that the charging pile charges each first target battery according to the second target charging parameter information; and

[0036] Controlling the disconnection of the charging circuits where the n second target batteries are located;

[0037] The second target charging parameter information includes a preset charging current, and the preset charging current is smaller than the first target charging current.

[0038] In this embodiment of the present application, after receiving charging completion information for the second target battery, second target charging parameter information is sent to the charging pile. Because the second target charging parameter information includes a preset charging current, which is lower than the first target charging current, the output current of the charging pile can be reduced. Next, the charging circuit containing the n second target batteries is controlled to be disconnected, thereby protecting the switch submodule in the charging circuit, thereby increasing the service life of the switch submodule and improving the reliability of battery charging.

[0039] In one embodiment of the present application, after controlling the charging circuits where the n second target batteries are located to be disconnected, the method further includes:

[0040] When n is less than m, determining third target charging parameter information according to the charging parameter information corresponding to each third target battery, wherein the third target battery is a battery that has not been completely charged among the first target batteries;

[0041] The third target charging parameter information is sent to the charging pile, so that the charging pile charges the uncharged battery in the first target battery according to the third target charging parameter information.

[0042] In an embodiment of the present application, after the charging circuit where the second target battery is located is disconnected, the charging parameter information is re-determined and sent to the charging pile, so that the battery in the first target battery that has not yet been fully charged can continue to be charged. There is no need for the user to manually operate the charging battery, and the charging parameters can be automatically adjusted, thereby effectively simplifying the charging process and improving convenience.

[0043] In one embodiment of the present application, determining the third target charging parameter information according to the charging parameter information corresponding to each third target battery includes:

[0044] Determine a second quantity corresponding to a third target battery according to the first quantity of the first target battery and the second quantity of the second target battery;

[0045] determining, according to the charging parameter information corresponding to each third target battery, a second charging current corresponding to each third target battery;

[0046] Third target charging parameter information is determined according to a minimum charging current among the second charging currents and a second number of third target batteries, where the third target charging parameter information includes the second target charging current.

[0047] In this embodiment of the present application, the number of uncharged batteries in the first target battery group and the minimum charging current among the second charging currents for the uncharged batteries are obtained, and a second target charging current is determined based on the minimum charging current among the second charging currents and the second number of the third target batteries. Based on this, when the charging pile outputs the charging current based on the second target current, it can solve the problem of potential battery overcurrent, thereby improving the reliability of the charging process and facilitating the improvement of battery life.

[0048] In an embodiment of the present application, during the process of charging each of the first target batteries, the method further includes:

[0049] Receive fault alarm information sent by BMS;

[0050] In response to the fault warning information, a stop charging message is sent to the charging pile, and the charging circuit where each first target battery in the charging control device is located is controlled to be disconnected.

[0051] In the embodiment of the present application, the fault alarm information of the BMS can be responded to in real time, so that the charging pile can be notified in time to stop power supply and disconnect the charging circuit to improve the reliability of the charging process.

[0052] In a third aspect, an embodiment of the present application provides an electronic device comprising a processor, a memory, and a program or instruction stored in the memory and executable on the processor.

[0067] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0068] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0069] The terms "first," "second," and the like in the specification and claims of this application or the accompanying drawings are used to distinguish between different objects, rather than to describe a specific order or a primary-secondary relationship. In the description of the embodiments of this application, "plurality" means more than two, unless otherwise specifically defined.

[0070] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0071] With the continuous development of science and technology, batteries are increasingly used in daily production and life. At present, more and more electrical devices include two or more independent battery management systems (BMS). When charging an electrical device, the user needs to operate the power supply to connect to each BMS separately in order to charge the battery corresponding to the BMS. Therefore, for an electrical device including multiple BMSs, the user needs to operate the power supply to connect to each BMS multiple times, making the charging process cumbersome.

[0072] In the related art, multiple charging ports are often provided on the power-consuming device to facilitate simultaneous charging of the batteries corresponding to each BMS by the power supplier. Consequently, when charging the power-consuming device, the user must connect multiple power suppliers to the charging ports. Once these power suppliers establish connections with the multiple charging ports, they communicate with the BMS to simultaneously charge multiple batteries, eliminating the need for the user to switch between power suppliers and different charging ports. However, this multi-point charging port approach introduces the inconvenience of finding a power supplier. For example, if the power-consuming device is a vehicle, and the vehicle includes two BMSs and two charging ports corresponding to each BMS, the user must find two charging stations to simultaneously charge the batteries corresponding to both BMSs. Alternatively, if the user charges the vehicle using a self-built charging station, this also requires the installation of two charging stations, further increasing the user's vehicle usage costs. Therefore, in the related art, since multiple independent BMSs require independent charging of each battery corresponding to the BMS, the user must plug and unplug the power supply facilities of the corresponding power supplier and organize the wiring, making the charging process cumbersome and increasing the overall charging time and user waiting time.

[0073] Based on the above considerations, to address the current issues of cumbersome charging procedures for electrical devices with multiple BMSs, high charging costs, increased charging times, and user waiting times, embodiments of the present application provide a charging control device, method, electronic device, and readable storage medium. The charging control device includes an input module, a charging switch module, and a control module. The input module is configured to connect to a charging station, and the charging switch module is configured to connect to at least one battery, each battery corresponding to a battery management system (BMS). This allows the charging control device to aggregate multiple BMSs within an electrical device. Specifically, when charging an electrical device is required, the control module can communicate with each BMS separately to obtain charging parameter information for one or more batteries, and then determine first target charging parameter information based on each charging parameter information. The control module then transmits the first target charging parameter information to the charging station, enabling the charging station to charge each first target battery according to the first target charging parameter information, eliminating the need for the user to manually switch communication with the charging station's BMS. Simultaneously, the control module activates the charging circuit for each first target battery, enabling charging of one or more batteries separately through a single charging station, effectively simplifying the charging process.

[0074] Furthermore, since the charging control device can simultaneously charge the batteries corresponding to multiple BMSs within the power-consuming device, the user only needs to find one charging station and charge the batteries corresponding to multiple BMSs within the power-consuming device in one operation, effectively simplifying the charging process, reducing charging time, and reducing user waiting time. Furthermore, based on the embodiments of the present application, the user does not need to set up additional charging stations, thereby saving user costs.

[0075] The charging control device disclosed in the embodiment of the present application can be used in, but is not limited to, electrical devices such as vehicles, ships, or aircraft. By using a power supply system comprising the electrical device including the charging control device disclosed in the present application, it is helpful to simplify the charging process and reduce the charging cost for users. In addition, the electrical device may also be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. Optionally, the charging control device may be installed in the electrical device, for example, by fixing the charging control device to the electrical device by installing a bracket. In addition, the charging control device may include a housing, and the housing may be made of a material with a protective function, thereby solving the problem of the external environment affecting the performance of the components in the charging control shell, thereby reducing the possibility of performance failure of the components in the charging control shell.

[0076] The following will describe in detail the charging control device, method, electronic device, and readable storage medium provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0077] Figure 1 A schematic diagram of the structure of a charging control device provided in an embodiment of the present application, combined with Figure 1 As shown, the charging control device 100 includes an input module 110 , a charging switch module 120 and a control module 130 .

[0078] The input module 110 is used to connect to a charging pile, and the charging switch module 120 is used to connect to at least one battery, wherein each battery corresponds to a battery management system BMS, and the control module 130 is respectively communicated with each BMS and charging pile;

[0079] The control module 130 is configured to obtain charging parameter information of at least one battery, and determine first target charging parameter information and at least one first target battery based on each charging parameter information, wherein the first target battery is a battery that the BMS allows the charging pile to charge;

[0080] The control module 130 is further configured to send first target charging parameter information to the charging pile, and control the charging circuit where each first target battery is located to be turned on, so that the charging pile charges each first target battery according to the first target charging parameter information.

[0081] Specifically, the input module 110 in the charging control device can be a charging interface for the power-consuming device. For example, the input module 110 can be the access port for the charging gun of a charging pile, and the charging pile can charge the battery to be charged through the input interface 110. The power-consuming device can include one or more BMSs, and a battery corresponding to each BMS. When there are multiple BMSs, the batteries corresponding to each BMS are independent of each other.

[0082] It will be understood that in the embodiments of the present application, a plurality refers to two, or more than two. The battery mentioned in the embodiments of the present application may refer to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the embodiments of the present application may include a battery module or a battery pack, etc. The battery generally includes a box for encapsulating one or more battery cells. Among them, the battery cell may include but is not limited to a lithium-ion secondary battery cell, a lithium-sulfur battery cell, a sodium-lithium-ion battery cell, a sodium-ion battery cell or a magnesium-ion battery cell, etc.

[0083] The charging switch module 120 can establish connections with multiple batteries in the electrical device respectively, and when the battery needs to be charged, it connects the charging circuit where the battery to be charged is located.

[0084] The control module 130 in the charging control device can communicate with the charging pile and the BMS in the power-consuming device, respectively. The communication connection methods include, but are not limited to, wired communication connection and wireless communication connection. Optionally, if the communication connection method is wired communication connection, the communication connection can be established through a low-voltage wiring harness, and the low-voltage wiring harness transmits the communication signals sent by the charging pile and the communication signals sent by each BMS. If the communication connection method is wireless communication connection, the communication method can be, but is not limited to, Bluetooth, wireless LAN, infrared communication, etc.

[0085] In an optional embodiment, after the charging pile establishes a communication connection with the control module 130, the control device 130 can, in response to the connection with the charging pile, send a charging request to each BMS in the power-consuming device, so that each BMS determines whether to allow the charging pile to charge the battery corresponding to its own system. Based on this, communication between the charging pile and multiple BMSs is achieved.

[0086] In another optional embodiment, after the charging pile establishes a communication connection with the control module 130, the charging pile may transmit its power supply information to the control device. For example, the power supply information may include, but is not limited to, the charging pile identifier, the maximum output current of the charging pile, and the maximum output voltage of the charging pile. Upon receiving the power supply information from the charging pile, the control device 130 may include the power supply information as part of a charging request, enabling the BMS to determine whether to allow the charging pile to charge the battery corresponding to its own system based on the power supply information. The BMS may determine whether the current charging pile can meet the charging requirements of the battery corresponding to its own system, taking into account factors such as differences between individual batteries and changes in battery performance during use. If the charging requirements are met, the BMS may allow the charging pile to charge the battery corresponding to its own system; if the requirements are not met, the BMS may not allow the charging pile to charge the battery corresponding to its own system. This improves the reliability of the battery charging process and reduces damage to the battery caused by rapid life degradation, overcharging, and poor battery consistency.

[0087] After receiving the charging request, the BMS may send charging parameter information to the control module 130. After receiving the charging parameter information, the control module 130 may aggregate the charging parameter information sent by each BMS and determine the total charging parameter information required by the electrical device, that is, the first target charging parameter information. It is understood that after receiving the charging request, if the charging pile is not allowed to charge the battery corresponding to its own system, the BMS may send a charging refusal message to the control module 130.

[0088] Continue to combine Figure 1 As shown, Figure 1The diagram shows two battery management systems BMS1 and BMS2 included in the power consumption device, where BMS1 corresponds to battery 1 and BMS2 corresponds to battery 2. The control module 130 can receive charging parameter information sent by BMS1 and charging parameter information sent by BMS2, and aggregate the charging parameter information sent by BMS1 and the charging parameter information sent by BMS2 to generate first target charging parameter information.

[0089] After determining the first target charging parameter information, the control module 130 can send the first target charging parameter information to the charging pile and control the charging circuit where each first target battery is located to conduct, so that the charging pile charges each first target battery according to the first target charging parameter information. In this way, a single charging pile can charge the batteries corresponding to multiple BMSs.

[0090] Based on the embodiment of the present application, when it is necessary to charge the electrical device, the control module can communicate with each BMS separately, so as to obtain the charging parameter information of one or more batteries, and then determine the first target charging parameter information in combination with each charging parameter information. Next, the control module sends the first target charging parameter information to the charging pile, so that the charging pile charges each first target battery according to the first target charging parameter information, without the need for the user to manually switch to communicate with the charging pile to connect to the BMS. At the same time, the control module controls the charging circuit where each first target battery is located to be turned on, so that one or more batteries can be charged separately through one charging pile, effectively simplifying the charging process.

[0091] In some embodiments, the power supply switch module 120 includes N parallel branches, the first end of each branch is connected to the input module, and the second end of each branch is used to connect to the battery; each branch includes a switch sub-module; each switch sub-module is communicatively connected to the control module and is used to perform conduction or shutdown in response to the first control signal of the control module.

[0092] It can be understood that N is a positive integer, and the charging switch module 120 may include one or more parallel branches. When the charging switch module 120 includes multiple parallel branches, the charging control device can charge multiple batteries corresponding to multiple BMSs respectively.

[0093] Figure 2 This is a structural diagram of another charging control device provided in an embodiment of the present application, combined with Figure 2 As shown, the power consumption device includes two BMSs and batteries corresponding to the two BMSs. In the charging switch module 120, the first end of each branch is connected to the input module 110, so that the charging current of the charging pile flows into the branch. The second end of each branch is connected to the battery corresponding to different BMSs, and the battery is connected to the battery. Figure 2As shown, the second end of the branch where the switch submodule 121 is located is electrically connected to the battery 1 corresponding to BMS1, and the second end of the branch where the switch submodule 122 is located is electrically connected to the battery 2 corresponding to BMS2. Optionally, the switch submodule may include but is not limited to controllable switch elements such as relays.

[0094] In the electrical device 100, each switch submodule can be communicatively connected to the control module 130. Specifically, the control module 130 controls the switching submodule to be turned on or off via a first control signal. For example, the first control signal can include a switch-on signal. When the battery corresponding to the switch submodule needs to be charged, the switch-on signal can be sent to the switch submodule, thereby turning on the charging circuit for the battery. The first control signal can also include a switch-off signal. When the battery corresponding to the switch submodule needs to stop charging, the switch-off signal can be sent to the switch submodule, thereby turning off the charging circuit for the battery.

[0095] For example, let's take the example of an electrical device including two BMSs and batteries corresponding to the two BMSs. Figure 2 As shown, when the charging pile is allowed to charge battery 1 and battery 2, the control module 130 can send a first control signal to the switch submodule 121 and the switch submodule 122 respectively. At this time, the first control signal includes a switch conduction signal.

[0096] In another example, when the charging pile is allowed to charge battery 1 but not allowed to charge battery 2, the control module 130 may send a first control signal to the switch submodule 121. At this time, the first control signal includes a switch-on signal; optionally, the control module 130 may not send the first control signal to the switch submodule 122. At this time, the switch submodule 122 remains in the off state. The control module 130 may send a first control signal to the switch submodule 122. At this time, the first control signal includes a switch-off signal, which still keeps the switch submodule 122 in the off state.

[0097] According to embodiments of the present application, the switch submodule included in each branch can be controlled to turn on or off, thereby charging the battery connected to the branch. Furthermore, in multiple parallel branches, the switch submodule in each branch can be flexibly controlled to turn on or off based on the charging needs of the battery corresponding to each branch, thereby improving the convenience of charging the electrical device.

[0098] In some embodiments, each branch further includes a battery protection module; in each branch, each battery protection module is connected in series between the first end and the switch submodule; wherein each battery protection module is unidirectionally conductive, and the current conduction direction of each battery protection module is from the first end to the second end.

[0099] As a specific example, Figure 3 A schematic diagram of the structure of another charging control device provided in the embodiment of the present application, combined with Figure 3 As shown, the power consumption device includes two BMSs and batteries corresponding to the two BMSs. In the charging switch module 120, the first end of each branch is connected to the input module 110, so that the charging current of the charging pile flows into the branch. The second end of each branch is connected to the battery corresponding to the different BMSs, and the battery protection module is connected in series between the first end and the switch submodule. Figure 3 As shown, the battery protection module 123 is connected in series between the first end and the switch submodule 121 , and the battery protection module 124 is connected in series between the first end and the switch submodule 122 .

[0100] Specifically, each battery protection module is unidirectionally conductive, with the current flowing from the first end to the second end. This solves the problem of circulating current between batteries. In particular, after the batteries are fully charged, this solves the problem of overcharging.

[0101] Optionally, the battery protection module may be a diode. In specific applications, the diode required in the charging control device can be selected based on the current flow requirements, the current level in the circuit, the voltage level in the circuit, as well as the charging power and heat dissipation requirements.

[0102] In this embodiment of the present application, a battery protection module is included between the first end of each branch and the switch submodule, and the battery protection module is only turned on when the current flows from the first end to the second end. This prevents current backflow during battery charging when the battery voltage exceeds the charging station voltage. Furthermore, because multiple batteries are connected in parallel through multiple branches, the battery protection module can prevent circulating charging caused by voltage inconsistencies between different batteries.

[0103] In some embodiments, the device also includes an insulation detection module, which is communicatively connected to the control module, and each charging switch module is connected to the input module through a high-voltage wiring harness; the insulation detection module is used to perform insulation detection on the high-voltage wiring harness during the charging process of the first target battery to obtain a detection result and send the insulation detection result to the control module.

[0104] Specifically, the charging switch module is connected between the battery and the charging pile. Therefore, the charging current output by the charging pile flows through the charging switch module and into the battery. Specifically, the high-voltage wiring harness serves as the connection between the input module, battery protection module, switch submodule and battery in the charging switch module. The high-voltage wiring harness can specifically include a high-voltage positive wiring harness and a high-voltage negative wiring harness.

[0105] During the charging process, based on the high-voltage positive wiring harness, the positive pole of the high-voltage DC current output by the charging pile can be connected to the high-voltage charging positive circuit of each independent BMS. Based on the high-voltage negative wiring harness, the negative pole of the high-voltage DC current output by the charging pile can be connected to the high-voltage charging negative circuit of each independent BMS, thereby forming a battery charging circuit.

[0106] Figure 4 A structural schematic diagram of another charging control device provided in an embodiment of the present application, specifically, the insulation detection module 140 is located between the input module 110 and the charging switch module 120. Through the insulation detection module 140, the high-voltage wire harness can be insulation detected and the insulation detection result can be obtained. For example, the insulation detection result may include the insulation resistance value. By sending the insulation detection result to the control module 130, the control module 130 can determine whether to continue charging the battery based on the insulation detection result.

[0107] In some embodiments, since the batteries corresponding to each BMS are connected to each parallel branch in the charging switch module 120, the insulation detection result is obtained by setting an insulation detection module, and each BMS does not need to perform the insulation detection step again, thereby solving the problem that the detection results of each BMS are prone to inaccurate detection results after the batteries are connected in parallel.

[0108] Optionally, the insulation detection module 130 can also send the insulation detection results to the main controller in the electrical device, for example, to the vehicle controller in the vehicle, so that the main controller can adjust the battery usage and thus improve the reliability of the electrical device.

[0109] In an embodiment of the present application, the insulation detection module can perform insulation detection on the high-voltage wire harness in the charging control device and send the detection results to the control module, thereby improving the reliability of the charging process.

[0110] Based on the charging control device provided in the embodiment of the present application, the embodiment of the present application also provides a charging control method. Figure 5 This is a flow chart of a charging control method provided by an embodiment of the present application, combined with Figure 5 As shown, the concept speculation method may include steps 510 to 530.

[0111] Step 510: Obtain charging parameter information of M batteries, wherein the M batteries are connected to a charging control device, and each battery has a one-to-one correspondence with a battery management system (BMS);

[0112] Step 520: Determine first target charging parameter information based on each charging parameter information, and determine m first target batteries, where the first target battery is a battery that the BMS allows the charging pile to charge, and 1≤m≤M;

[0113] Step 530 : Send the first target charging parameter information to the charging pile, and control the charging circuit where each first target battery in the charging control device is located to be turned on, so that the charging pile charges each first target battery according to the first target charging parameter information.

[0114] The above steps are described in detail below.

[0115] In steps 510 and 520 above, different BMSs in the power consumption device are respectively connected to the charging control device, and charging parameter information is transmitted by the BMS in the power consumption device. The power consumption device may include multiple BMSs, each corresponding to a different battery. It is understood that M is a positive integer.

[0116] As a specific example, when a BMS in an electrical device requires charging, it can proactively send charging parameter information to the charging control device. The charging control device can then send a charging request to each BMS in the electrical device. Upon receiving the charging request, the BMS in the electrical device can feed back the charging parameter information to the charging control device. Optionally, after receiving the charging request, if the BMS does not allow the charging station to charge the battery corresponding to its own system, the charging parameter information sent to the control module 130 may include a charge rejection message, or the BMS may not feed back the charging parameter information.

[0117] For example, the power-consuming device includes multiple BMSs. If each BMS allows the current charging pile to charge the battery corresponding to its own system, then M is equal to m; if some of the multiple BMSs allow the current charging pile to charge the battery corresponding to its own system, then M is less than m.

[0118] Based on this, in the embodiment of the present application, the charging control device summarizes the received charging parameter information and determines the total charging parameter information required by the power-consuming device, i.e., the first target charging parameter information. The charging control device can also determine the battery allowed to be charged, i.e., the first target battery, based on the received charging parameter information.

[0119] Next, in step 530, after determining the first target charging parameter information and the first target battery, the charging control device can send the first target charging parameter information to the charging pile and control the charging circuit where each first target battery is located to be connected, so that the charging pile charges each first target battery according to the first target charging parameter information. In this way, a single charging pile can charge the batteries corresponding to multiple BMSs.

[0120] According to an embodiment of the present application, when it is necessary to charge an electrical device, the charging parameter information of one or more batteries is obtained, and the first target charging parameter information and the first target battery to be charged are determined by combining each charging parameter information. Next, the first target charging parameter information is sent to the charging pile so that the charging pile charges each first target battery according to the first target charging parameter information. This eliminates the need for the user to manually switch the communication connection with the charging pile to the BMS, thereby simplifying the charging operation. At the same time, the control module controls the charging circuit where each first target battery is located to be turned on, thereby realizing charging of one or more batteries separately through one charging pile, effectively simplifying the charging process.

[0121] In some embodiments, before obtaining the charging parameter information of the M batteries, the method further includes:

[0122] In response to establishing a connection with the charging pile, charging request information is sent to M BMSs respectively, so that each BMS feeds back charging parameter information of the battery.

[0123] For example, the charging pile may include a charging gun, which a user can control to connect to the input interface of the charging control device, thereby enabling the charging pile to charge the battery through the charging control device. The charging control device may be in communication with the charging pile, where the communication connection method includes but is not limited to a wired communication connection and a wireless communication connection. After the charging pile establishes a communication connection with the charging control device, the charging pile's power supply information can be obtained, and the charging pile can send its own power supply information to the control device. For example, the power supply information includes but is not limited to the following information: the charging pile identification, the charging pile's maximum output current, the charging pile's maximum output voltage, etc.

[0124] In response to the connection with the charging pile, the charging control device sends a charging request to each BMS in the power-consuming device, so that each BMS determines whether to allow the charging pile to charge the battery corresponding to its own system. Optionally, after obtaining the power supply information of the charging pile, the charging control device can use the power supply information as part of the charging request, so that the BMS determines whether to allow the charging pile to charge the battery corresponding to its own system based on the power supply information. Among them, the BMS can combine factors such as the differences between different individual batteries and the changes in battery performance of different batteries during use to determine whether the current charging pile can meet the charging needs of the battery corresponding to its own system. If the charging needs are met, the charging pile is allowed to charge the battery corresponding to its own system, and if the charging needs are not met, the charging pile is not allowed to charge the battery corresponding to its own system, thereby improving the reliability of the battery charging process and reducing damage to the battery such as rapid life decay, overcharging, and poor battery consistency.

[0125] According to an embodiment of the present application, after establishing a connection with the charging pile, the charging control device sends charging request information to M BMSs, without the need for the user to manually switch the communication connection with the charging pile to the BMS, thereby realizing communication between the charging pile and multiple BMSs.

[0126] Based on the above embodiment, the BMS in the power-consuming device can feed back charging parameter information to the charging control device so that the charging pile outputs the charging current.

[0127] In some embodiments, each charging parameter information includes a first charging current for each battery, and the first target charging parameter information includes a first target charging current;

[0128] Specifically, in step 520 , first target charging parameter information is determined according to each charging parameter information, which may include steps 5201 and 5202 .

[0129] Step 5201, determining a first number of first target batteries and a first charging current of each first target battery;

[0130] Step 5202 : Determine a first target charging current according to a minimum charging current among the first charging currents and a first number of first target batteries.

[0131] Exemplarily, in the first charging current of the charging parameter information, the first charging current may include but is not limited to the current range allowed for battery charging, the maximum current value allowed for battery charging, etc.

[0132] The charging control device can determine the first target batteries that need to be charged according to the received charging parameter information, and obtain the first charging current corresponding to each first target battery, thereby obtaining the minimum charging current among the required rechargeable batteries.

[0133] The first target charging current is obtained by determining a minimum charging current among the m first charging currents and calculating a product of the minimum charging current and the number of first target batteries.

[0134] Optionally, the first target charging parameter information may further include the charging voltage of the battery, wherein the charging voltage of the charging pile needs to be greater than the voltage of the battery.

[0135] According to an embodiment of the present application, a first target charging current is determined by determining a first number m of first target batteries and a minimum charging current among the m first charging currents. Based on this, when the charging pile outputs a charging current based on the first target current, it can address the potential overcurrent issue in the battery, thereby improving the reliability of the charging process and facilitating longer battery life.

[0136] In some embodiments, after sending the first target charging parameter information to the charging pile and controlling the charging circuit where each first target battery in the charging control device is located to be turned on, the charging control method further includes steps 601 to 603 .

[0137] Step 601: Receive charging completion information of n second target batteries, where the second target batteries are the batteries that have been fully charged among the m first target batteries, 1≤n≤m;

[0138] Step 602: In response to the charging completion information of the n second target batteries, second target charging parameter information is sent to the charging pile, so that the charging pile charges each first target battery according to the second target charging parameter information; and

[0139] Step 603: Control the charging circuits where the n second target batteries are located to be disconnected.

[0140] The second target charging parameter information includes a preset charging current, and the preset charging current is smaller than the first target charging current.

[0141] Specifically, in step 601, the second target battery is a battery that has been fully charged among the m first target batteries. After the second target battery is fully charged, the BMS corresponding to the second target battery can send a charging completion message to the charging control device so that the charging control device disconnects the charging circuit in time to reduce the overcharging of the second target battery.

[0142] The number of the second target batteries may be one or more. It is understandable that the number of the second target batteries is less than or equal to the number of the first target batteries.

[0143] Next, referring to the above steps 602 and 630 , the charging control device sends second target charging parameter information to the charging pile in response to the charging completion information of the second target battery, so that the charging pile charges each first target battery according to the second target charging parameter information.

[0144] For example, the second target charging parameter information may include a preset charging current, and the preset charging current is less than the first target charging current. Optionally, the preset charging current may be determined based on an operating current range within which the switch submodule in the charging control device normally switches.

[0145] When controlling the charging circuit where the second target battery is located to be disconnected, it may specifically include controlling the switch submodule in the charging circuit where the second target battery is located to be turned off, thereby cutting off the charging circuit. Optionally, the switch submodule includes a switch element such as a relay.

[0146] According to an embodiment of the application, after receiving charging completion information for the second target battery, second target charging parameter information is sent to the charging pile. Because the second target charging parameter information includes a preset charging current, and the preset charging current is less than the first target charging current, the output current of the charging pile can be reduced. Next, the charging circuit containing the n second target batteries is controlled to disconnect, thereby protecting the switch submodule in the charging circuit, thereby increasing the service life of the switch submodule and improving the reliability of battery charging.

[0147] In some embodiments, after controlling the charging loops where the n second target batteries are located to be disconnected, the method may further include step 604 and step 605 .

[0148] Step 604, when n is less than m, determining third target charging parameter information based on the charging parameter information corresponding to each third target battery, wherein the third target battery is a battery in the first target battery that has not been completely charged;

[0149] Step 605 : Send third target charging parameter information to the charging pile, so that the charging pile charges the uncharged battery in the first target battery according to the third target charging parameter information.

[0150] Specifically, when n is less than m, it indicates that the m first target batteries also include batteries whose charging is not completed. For the convenience of description, the batteries whose charging is not completed among the m first target batteries are referred to as third target batteries.

[0151] Next, the charging control device can automatically determine the charging parameters required for the remaining third target batteries, obtain the third target charging parameter information, and send the third target charging parameter information to the charging pile so that the charging pile can charge the batteries in the first target battery that have not been fully charged according to the third target charging parameter information.

[0152] According to an embodiment of the present application, after the charging circuit where the second target battery is located is disconnected, the charging parameter information is re-determined and sent to the charging pile, so that the battery in the first target battery that has not yet been fully charged can continue to be charged. There is no need for the user to manually operate the charging battery, and the charging parameters can be automatically adjusted, thereby effectively simplifying the charging process and improving convenience.

[0153] In some embodiments, determining the third target charging parameter information according to the charging parameter information corresponding to each third target battery includes:

[0154] Determine a second quantity corresponding to a third target battery according to the first quantity of the first target battery and the second quantity of the second target battery;

[0155] determining, according to the charging parameter information corresponding to each third target battery, a second charging current corresponding to each third target battery;

[0156] Third target charging parameter information is determined according to a minimum charging current among the second charging currents and a second number of third target batteries, where the third target charging parameter information includes the second target charging current.

[0157] Specifically, the number of the first target batteries is m, the number of the second target batteries is n, and the second number corresponding to the third target batteries can be obtained by calculation.

[0158] Optionally, the charging parameter information corresponding to each third target battery may be sent by the BMS to the charging control device. For example, each time the charging control device establishes a connection with the charging pile and sends a charging request to each BMS, the BMS feeds back the charging parameter information of the battery corresponding to its own system to the charging control device. The charging control device caches the charging parameter information of each battery until the current charging is completed. The charging control device can then choose to retain or delete the cached charging parameter information.

[0159] In this embodiment of the present application, the charging control device can obtain the third charging parameter information corresponding to each third target battery from the cache, thereby obtaining the second charging current corresponding to each third target battery. The second charging current may include, but is not limited to, the current range allowed for battery charging, the maximum current value allowed for battery charging, etc.

[0160] Next, the second target charging current is obtained by determining a minimum charging current among all the second charging currents and calculating a product of the minimum charging current and the number of the third target batteries.

[0161] In the embodiment of the present application, the number of uncharged batteries in the first target battery group and the minimum charging current among the second charging currents of the uncharged batteries are obtained, and a second target charging current is determined based on the minimum charging current among the second charging currents and the second number of the third target batteries. Based on this, the output current of the charging pile can be updated in a timely manner. When the charging pile outputs the charging current based on the second target current, the problem of potential battery overcurrent can be resolved, thereby improving the reliability of the charging process and facilitating the improvement of battery life.

[0162] In some embodiments, during the charging process of each first target battery, the method further includes: receiving fault warning information sent by the BMS; in response to the fault warning information, sending a stop charging information to the charging pile, and controlling the charging circuit where each first target battery in the charging control device is located to be disconnected.

[0163] Specifically, each BMS in the power-consuming device can detect in real time whether the battery corresponding to its own system has a fault, for example, abnormal battery temperature rise, etc. At this time, the BMS can generate a fault alarm message and send the fault alarm message to the charging control device.

[0164] After receiving the fault warning information, the charging control device sends a stop charging message to the charging pile and controls the charging circuit where each first target battery in the charging control device is located to be disconnected, thereby stopping charging the battery in the power-consuming device.

[0165] In the embodiment of the present application, the fault alarm information of the BMS can be responded to in real time, so that the charging pile can be notified in time to stop power supply and disconnect the charging circuit to improve the reliability of the charging process.

[0166] In order to more clearly introduce the technical solution of this application, Figure 6 A flow chart of another charging control method provided in an embodiment of the present application, combined with Figure 6 As shown, the charging control method may include steps 701 to 712 .

[0167] In step 701 , in response to being connected to a charging pile, the charging control device sends charging request information to a plurality of BMSs in the power-consuming device.

[0168] Step 702: The charging control device receives charging parameter information of the battery.

[0169] The plurality of BMSs respectively send battery charging parameter information to the charging control device in response to the charging request information.

[0170] Step 703: The charging control device determines the number of first target batteries and a first charging current corresponding to each first target battery according to the charging parameter information;

[0171] In step 704 , the charging control device determines a first target charging current according to the number of the first target batteries and the minimum current among the first charging currents.

[0172] In step 705 , the charging control device sends a first target charging current to the charging pile, and controls the charging circuit where the first target battery is located to be turned on.

[0173] Step 706: The charging pile outputs a first target charging current.

[0174] In step 707 , the first BMS among the multiple BMSs sends charging completion information to the charging control device.

[0175] In step 708 , the charging control device sends the second target charging parameter information to the charging pile, and controls the charging circuit corresponding to the battery of the first BMS to be disconnected, so that the charging pile outputs a preset charging current.

[0176] Specifically, the second target charging parameter information includes a preset charging current.

[0177] In step 709 , the charging control device determines a second quantity corresponding to the third target batteries and a second charging current corresponding to each of the third target batteries.

[0178] In step 710 , the charging control device determines the third target charging parameter information according to the minimum charging current among the second charging currents and the second number of the third target batteries, where the third target charging parameter information includes the second target charging current.

[0179] Step 711: The charging control device sends third target charging parameter information to the charging pile.

[0180] Step 712: The charging pile charges the uncharged batteries in the first target batteries according to the third target charging parameter information.

[0181] During the subsequent charging process of the third target battery, the charging control device may continue to receive the charging completion information sent by the BMS and continue to charge the battery according to the processing method of steps 707 to 712 until charging is completed and all charging circuits in the charging control device are disconnected.

[0182] According to an embodiment of the present application, when it is necessary to charge an electrical device, the first target charging parameter information is determined by obtaining the charging parameter information of one or more batteries and combining each charging parameter information. Next, the first target charging parameter information is sent to the charging pile so that the charging pile charges each first target battery according to the first target charging parameter information. This eliminates the need for the user to manually switch the communication connection with the charging pile to the BMS, thereby simplifying the charging operation. At the same time, the control module controls the charging circuit where each first target battery is located to be turned on, thereby enabling charging of one or more batteries separately through one charging pile, effectively simplifying the charging process.

[0183] Based on the charging control device provided in the embodiment of the present application, the embodiment of the present application also provides a charging control system, Figure 7 This is a schematic diagram of the structure of a charging control system provided by an embodiment of the present application.

[0185] The charging control system of the embodiment of the present application, when it is necessary to charge an electrical device, obtains the charging parameter information of one or more batteries and determines the first target charging parameter information by combining each charging parameter information. Next, by sending the first target charging parameter information to the charging pile, the charging pile charges each first target battery according to the first target charging parameter information, without the need for the user to manually switch the communication connection with the charging pile to the BMS, thereby simplifying the charging operation. At the same time, the control module controls the charging circuit where each first target battery is located to be turned on, so that one or more batteries can be charged separately through one charging pile, effectively simplifying the charging process.
