[0056] The following describes the present application based on embodiments, but the present application is not limited to these embodiments. In the following detailed description of the present application, some specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these details. In order to avoid obscuring the essence of the present application, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0057] In addition, those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0058] At the same time, it should be understood that in the following description, a "circuit" refers to a conductive loop formed by at least one element or sub-circuit through electrical connection or electromagnetic connection. When an element or circuit is said to be "connected to" another element or when an element / circuit is said to be "connected between" two nodes, it can be directly coupled or connected to another element or there can be intermediate elements, and the connection between elements can be physical, logical, or a combination thereof. On the contrary, when an element is said to be "directly coupled to" or "directly connected to" another element, it means that there are no intermediate elements

[0059] Unless the context clearly requires otherwise, words such as "including" and "comprising" in the entire application document should be interpreted as having an inclusive meaning rather than an exclusive or exhaustive meaning; that is, it is the meaning of "including but not limited to".

[0060] In the description of the present application, it should be understood that terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more. In addition, the solutions described in this specification and the embodiments, if related to personal information processing, will be processed on the premise of having a legal basis (such as obtaining the consent of the personal information subject or being necessary for performing a contract), and will only be processed within the specified or agreed scope. If the user refuses to process personal information other than the necessary information required for basic functions, it will not affect the user's use of basic functions.

[0061] With the development of new energy technologies, the standards corresponding to new energy devices are constantly changing to meet corresponding usage and safety requirements. For example, in order to meet the driving safety requirements of current electric bicycles (i.e., two-wheeled electric vehicles), new national standard electric bicycles and corresponding new national standard batteries have been introduced currently.

[0062] Currently, platforms providing charging services (including but not limited to shared electric bicycle service platforms, shared electric vehicle service platforms, electric bicycle charging service platforms, electric vehicle charging service platforms, battery charging service platforms, etc.) will set up a number of charging devices in different areas to provide charging services to new energy devices or the batteries therein. However, after the battery corresponding standard has changed once or multiple times, the already set charging devices may not be able to adapt to the batteries of the new standard.

[0063] Taking a charging cabinet and a new national standard battery as an example, multiple charging ports can be set in the charging cabinet for multiple batteries to charge simultaneously. Currently, most charging cabinets were set up before the new national standard battery emerged. After the new national standard battery emerged, in order to meet the new national standard, the battery system architecture of the battery has been correspondingly changed, which makes the existing charging cabinets unable to be compatible with the new national standard batteries (that is, the charging cabinets cannot charge the new national standard batteries), thus affecting the charging path of the new national standard batteries to a certain extent.

[0064] Regarding the problem that the above-mentioned charging devices are not compatible with the new standard batteries, producing and setting up new charging devices for the new standard batteries can solve this problem. However, setting up new charging devices will consume a large amount of manpower and material resources. Moreover, if the battery standard is updated again, the charging devices need to be reset again. Therefore, producing and setting up new charging devices is not an effective means to solve the above problem. That is to say, how to make the existing charging devices compatible with the new standard batteries is an urgent problem to be solved currently.

[0065] To solve the above problem, an embodiment of the present application provides a charging control system, as well as a charging control method applied in the charging control system. Specifically, as Figure 1 shown, the charging control system of the embodiment of the present application may include a battery 11 and a charging device 12. The battery 11 may include a battery system 111, and the charging device 12 may include at least one charging port for charging. Among them, the charging device 12 may be a charging device in a one-to-one mode (such as a charging pile and other devices including only one charging port), or a charging device in a one-to-many mode (such as a charging cabinet and other devices including multiple charging ports). The battery 11 and the charging device 12 may be connected through the charging port of the charging device 12, and the battery system 111 may transmit data and information with the charging device 12 through the charging port.

[0066] Specifically, the embodiment of the present application provides a charging control method for the battery system 111 and the charging device 12 respectively, that is, the embodiment of the present application provides a charging control method applied to the battery system 111 and a charging control method applied to the charging device 12.

[0067] On one side of the battery system 111, embodiments of the present application can determine the battery connection state of the target battery (i.e., battery 11). In response to the battery connection state being connected to the charging device, close the auxiliary circuit of the target battery. In response to receiving the connection feedback information sent by the charging device 12, disconnect the auxiliary circuit, and send charging demand information to the charging device 12 so that the charging device 12 charges the target battery according to the charging demand information.

[0068] On one side of the charging device 12, embodiments of the present application can determine the port connection state of at least one charging port. In response to any charging port being connected to the target battery, send connection feedback information to the target battery so that the target battery disconnects the auxiliary circuit. In response to receiving the charging demand information sent by the target battery, charge the target battery according to the charging demand information.

[0069] Among them, the target battery is the battery 11 connected to the charging port. The target battery includes the battery system 111. The connection feedback information is used to indicate that the charging device 12 detects a connection with the target battery. The auxiliary circuit in the target battery is mainly a circuit for performing signal acquisition, amplification and transmission, control, regulation and data storage. After the auxiliary circuit is closed, the charging device 12 can obtain the battery data corresponding to the battery 11 through the auxiliary circuit to control the charging current, charging voltage, start, termination, pause and other corresponding actions according to the battery data.

[0070] Through actual tests, it is found that in the process of the existing charging devices (such as the above-mentioned charging cabinet) connecting to the new standard battery (such as the above-mentioned new national standard battery) and charging the new standard battery, if the auxiliary circuit is in a closed state during charging, it may cause a short circuit inside the charging device, resulting in charging interruption and even safety accidents.

[0071] To effectively solve this problem, in embodiments of the present application, the battery system 111 in the charging control system can actively disconnect the auxiliary circuit after receiving the connection feedback information sent by the charging device 12, so that the auxiliary circuit in the battery 11 always remains disconnected during the charging process of the charging device 12 to the battery 11. Further, since the charging device 12 cannot obtain the battery data corresponding to the battery 11 after the auxiliary circuit is disconnected, the charging device 12 cannot determine appropriate charging current and charging voltage data when the auxiliary circuit is disconnected. In response to this situation, the battery system 111 of embodiments of the present application can actively send charging demand information to the charging device 12 after disconnecting the auxiliary circuit. Correspondingly, the charging device 12 can receive the charging demand information sent by the battery system 111 and charge the battery 11 according to the charging demand information.

[0072] It can be seen that the embodiments of the present application can effectively avoid the influence of the auxiliary circuit on the charging process and improve the compatibility between the charging device 12 and batteries of different standards by disconnecting the auxiliary circuit before charging and actively sending charging demand information from the battery system 111 to the charging device 12 on the premise of ensuring the smooth progress of the charging process.

[0073] Next, a charging control method provided by the embodiments of the present application will be described in detail in combination with specific embodiments. As Figure 2 shown, the charging control method applied to the battery system side may specifically include the following steps:

[0074] In step S110, determine the battery connection status of the target battery.

[0075] Among them, the target battery may include a battery system. That is to say, the target battery in the embodiments of the present application can be used to represent the battery in the charging scenario. The battery system is a system set in the target battery for managing the battery. The battery system can detect the battery connection status of the target battery in real time, that is, detect in real time whether the target battery is connected to the charging port of the charging device. If the target battery is connected to the charging port of the charging device, the battery connection status of the target battery is connected to the charging device. If the target battery is not connected to the charging port of the charging device, the battery connection status of the target battery is not connected to the charging device.

[0076] In step S120, in response to the battery connection status being connected to the charging device, close the auxiliary circuit of the target battery.

[0077] Among them, the auxiliary circuit in the target battery is mainly a circuit for performing signal acquisition, amplification and transmission, control, regulation and data storage. After the auxiliary circuit is closed, the charging device can obtain the battery data corresponding to the target battery through the auxiliary circuit to control the charging current, charging voltage, start, termination, pause and other corresponding actions according to the battery data.

[0078] In the embodiments of the present application, the battery system controls to close the auxiliary circuit of the target battery, which can enable the charging device to normally detect whether the target battery is successfully connected to the charging port.

[0079] In step S130, in response to receiving the connection feedback information sent by the charging device, disconnect the auxiliary circuit.

[0080] Among them, the connection feedback information is used to represent that the charging device detects the connection with the target battery. That is to say, when the battery system receives the connection feedback information, it means that the charging device has completed the corresponding port connection detection action. Further, the battery system can control the auxiliary circuit to disconnect at this time to avoid the influence of the auxiliary circuit on the charging process.

[0081] In step S140, charging demand information is sent to the charging device so that the charging device charges the target battery according to the charging demand information.

[0082] In the embodiment of the present application, after receiving the connection feedback information sent by the charging device, the battery system can actively disconnect the auxiliary circuit, so that during the charging process of the charging device to the target battery, the auxiliary circuit in the target battery always remains disconnected. Further, after disconnecting the auxiliary circuit, the battery system can actively send charging demand information to the charging device so that the charging device charges the target battery according to the charging demand information. Therefore, the embodiment of the present application can effectively avoid the influence of the auxiliary circuit on the charging process and improve the compatibility of the charging device with batteries of different standards (especially enabling existing charging devices to be compatible with new standard batteries) by disconnecting the auxiliary circuit before charging and actively sending charging demand information by the battery system on the premise of ensuring the smooth progress of the charging process.

[0083] In an alternative embodiment, the above step S140 may be executed as: in response to disconnecting the auxiliary circuit, after waiting for a predetermined duration, close the main circuit and send charging demand information to the charging device.

[0084] Wherein, the main circuit is the power circuit for transmitting electric energy in the target battery, and the predetermined duration may be a value set according to the actual situation. For example, the predetermined duration may be 300 ms (milliseconds), 500 ms or 1 s (second), etc.

[0085] In practical applications, since electric arcs are generated at the moment of closing / opening of both the auxiliary circuit and the main circuit (especially for the main circuit with high voltage and large current intensity, the released electric arc is relatively strong), therefore, the embodiment of the present application can set a predetermined duration between the moment of disconnecting the auxiliary circuit and the moment of closing the main circuit, so that the battery system closes the main circuit after the auxiliary circuit is completely disconnected, thereby effectively avoiding the mutual interference between the auxiliary circuit and the main circuit.

[0086] In an alternative embodiment, the charging demand information of the embodiment of the present application may at least include a charging start request, a charging current demand, and a charging voltage demand.

[0087] Among them, the charging start request may be a charging enable signal. When requesting to start charging, the charging enable signal is a signal allowing charging. The battery system can request the charging device to start charging by sending a charging enable signal to the charging device. For example, the battery system can send a charging enable signal with a value of "1" to the charging device. Correspondingly, after receiving the charging enable signal with a value of "1", the charging device can charge the target battery according to the charging current corresponding to the charging current demand and the charging voltage corresponding to the charging voltage demand.

[0088] In the embodiment of the present application, since the battery system can actively send charging demand information to the charging device after disconnecting the auxiliary circuit, so that the charging device charges the target battery according to the charging current demand and the charging voltage demand. Therefore, the embodiment of the present application can effectively avoid the influence of the auxiliary circuit on the charging process on the premise of ensuring the smooth progress of the charging process, and improve the compatibility between the charging device and batteries of different standards.

[0089] In addition, the charging demand information in the embodiment of the present application may further include information such as charging time demand. Among them, the charging time demand can be used to represent the duration required for charging, or can be used to represent the moment when charging needs to be terminated. By adding the charging time demand to the charging demand information, the embodiment of the present application can enable the charging device to pre-determine the moment to terminate charging (if the charging time demand is the duration required for charging, the charging device can add the moment when the charging demand information is received to the duration required for charging to determine the moment to terminate charging), without obtaining the battery data of the target battery during the charging process, and realize automatically stopping charging at the moment to terminate charging.

[0090] In an alternative embodiment, as Figure 3 shown, the embodiment of the present application may further include the following steps:

[0091] In step S210, detect the charging current.

[0092] Among them, the charging current is the current that the charging device charges into the target battery. The battery system can detect the charging current in the target battery. If the battery system detects the charging current, it indicates that the charging device has started charging the target battery.

[0093] In step S220, in response to detecting an effective charging current, perform a charging end detection.

[0094] Among them, the embodiment of the present application can preset one or more charging end conditions for the charging end detection. For example, the charging end conditions may include "reaching a predetermined charging duration from the moment when the effective charging current is first detected" and "no interruption of the charging current is detected". Among them, the predetermined charging duration can be set according to the actual situation (such as 4 hours, 8 hours or 10 hours, etc.). When the battery system detects that the charging end conditions are met, the battery system can request the charging device to end the charging.

[0095] It should be noted that the charging end conditions in the embodiment of the present application are not limited to the above examples. The embodiment of the present application can set one or more charging end conditions according to the actual situation. For example, the charging end conditions may also include "the power of the target battery reaches a predetermined power threshold" or "receiving a charging end instruction", etc.

[0096] In step S230, in response to satisfying the charging end condition, a charging end request is sent to the charging device to cause the charging device to end the charging.

[0097] Among them, the charging end request in the embodiments of the present application can also be a charging enable signal. That is to say, the battery system can request the charging device to stop charging by sending a charging enable signal for requesting to end the charging to the charging device. For example, the battery system can send a charging enable signal with a value of "0" to the charging device. Correspondingly, after receiving the charging enable signal with a value of "0", the charging device can stop charging the target battery.

[0098] In the embodiments of the present application, the battery system can actively disconnect the auxiliary circuit after receiving the connection feedback information sent by the charging device, so that the auxiliary circuit in the target battery remains disconnected all the time during the process of the charging device charging the target battery. Further, after disconnecting the auxiliary circuit, the battery system can actively send charging demand information to the charging device, so that the charging device charges the target battery according to the charging demand information. Therefore, the embodiments of the present application can effectively avoid the influence of the auxiliary circuit on the charging process and improve the compatibility of the charging device with batteries of different standards (especially enabling existing charging devices to be compatible with new standard batteries) by disconnecting the auxiliary circuit before charging and the battery system actively sending charging demand information to the charging device on the premise of ensuring the smooth progress of the charging process.

[0099] The above is the description of the charging control method applied on the battery system side. Correspondingly, as Figure 4 shown, the charging control method applied on the charging device side can specifically include the following steps:

[0100] In step S310, determine the port connection status of at least one charging port.

[0101] Among them, the number of charging ports of the charging device can be one or more. Each charging port can be respectively connected to a battery, and the battery system in the battery can transmit data and information through the charging port with the charging device. In the embodiments of the present application, the charging device can be a charging device in a one-to-one mode (such as a charging pile and other devices including only one charging port), or a charging device in a one-to-many mode (such as a charging cabinet and other devices including multiple charging ports).

[0102] In step S320, in response to any charging port being connected to the target battery, send connection feedback information to the target battery to cause the target battery to disconnect the auxiliary circuit.

[0103] Among them, the target battery is the battery connected to the charging port, and the connection feedback information is used to indicate that the charging device detects the connection with the target battery. When the charging device detects that the target battery is successfully connected to the charging port, the charging device can inform the battery system of the target battery through the connection feedback information. Further, after receiving the connection feedback information, the battery system can control the auxiliary circuit to disconnect to avoid the influence of the auxiliary circuit on the charging process.

[0104] In step S330, in response to receiving the charging demand information sent by the target battery, charge the target battery according to the charging demand information.

[0105] In the embodiment of the present application, after detecting the connection of any charging port to the target battery, the charging device can send connection feedback information to the target battery, so that after receiving the connection feedback information sent by the charging device, the battery system actively disconnects the auxiliary circuit, and further, during the charging process of the charging device to the target battery, the auxiliary circuit in the target battery always remains disconnected. Further, the charging device can receive the charging demand information actively sent by the target battery and charge the target battery according to the charging demand information. Therefore, the embodiment of the present application can effectively avoid the influence of the auxiliary circuit on the charging process while ensuring the smooth progress of the charging process by disconnecting the auxiliary circuit before charging and having the target battery actively send the charging demand information to the charging device, improving the compatibility of the charging device with batteries of different standards (especially enabling existing charging devices to be compatible with new standard batteries).

[0106] In an alternative embodiment, the charging demand information actively sent by the target battery to the charging device may at least include a charging start request, a charging current demand, and a charging voltage demand.

[0107] Among them, the charging start request may be a charging enable signal. When requesting to start charging, the charging enable signal is a signal allowing charging. The target battery can send a charging enable signal to the charging device through the battery system to request the charging device to start charging. For example, the target battery can send a charging enable signal with a value of "1" to the charging device. Correspondingly, after receiving the charging enable signal with a value of "1", the charging device can charge the target battery according to the charging current corresponding to the charging current demand and the charging voltage corresponding to the charging voltage demand.

[0108] In the embodiment of the present application, since the target battery can actively send the charging demand information to the charging device after disconnecting the auxiliary circuit, so that the charging device charges the target battery according to the charging current demand and the charging voltage demand, therefore, the embodiment of the present application can effectively avoid the influence of the auxiliary circuit on the charging process while ensuring the smooth progress of the charging process, improving the compatibility of the charging device with batteries of different standards.

[0109] In addition, the charging demand information in the embodiments of the present application may further include information such as charging time demand. Among them, the charging time demand may be used to represent the duration of charging required, or may be used to represent the moment when charging needs to be terminated. By adding the charging time demand to the charging demand information, the embodiments of the present application can enable the charging device to pre-determine the moment to terminate charging (if the charging time demand is the duration of charging required, the charging device can add the moment when the charging demand information is received to the duration of charging required to determine the moment to terminate charging), without obtaining the battery data of the target battery during the charging process, and achieve automatically stopping charging at the moment of terminating charging.

[0110] In an alternative embodiment, the embodiments of the present application may further include the following steps: in response to receiving a charging end request sent by the target battery, stop charging the target battery.

[0111] Among them, the charging end request in the embodiments of the present application may also be a charging enable signal. That is to say, the battery system may request the charging device to stop charging by sending a charging enable signal for requesting to end charging to the charging device. For example, the battery system may send a charging enable signal with a value of "0" to the charging device. Correspondingly, after receiving the charging enable signal with a value of "0", the charging device may stop charging the target battery.

[0112] Combined with the above embodiments of automatically stopping charging at the moment of terminating charging, it can be seen that the charging device in the embodiments of the present application can end charging through multiple preset methods. The preset methods may at least include the charging device actively stopping charging according to the charging time demand, and / or the target battery actively sending a charging end request to the charging device through the battery system to request the charging device to stop charging.

[0113] Therefore, the embodiments of the present application can effectively avoid the influence of the auxiliary circuit on the charging process on the premise of ensuring the smooth progress of the charging process by disconnecting the auxiliary circuit before charging and the way that the target battery actively sends charging demand information to the charging device, and improve the compatibility of the charging device and batteries of different standards (especially enabling existing charging devices to be compatible with new standard batteries).

[0114] The above is the description of the charging control method applied on the charging device side. Further, for the interaction between the battery system of the battery and the charging device, as Figure 5 shown, it may specifically include the following steps:

[0115] In step S511, the battery system 111 determines the battery connection state. If the battery state is connected to the charging device, step S512 is executed; if the battery state is not connected to the charging device, step S511 is executed.

[0116] Among them, the battery connection state is the connection state of the battery in which the battery system 111 is located.

[0117] In step S512, the battery system 111 closes the auxiliary circuit.

[0118] Correspondingly, on the charging device 12 side, the charging device 12 can execute:

[0119] In step S521, the charging device 12 determines the port connection state. If the port state is connected to the battery, step S522 is executed. If the battery state is not connected to the battery, step S521 is executed.

[0120] Among them, the battery connected to the charging device 12 is the target battery.

[0121] In step S522, the charging device 12 sends connection feedback information to the battery system 111 of the target battery. Correspondingly, the battery system 111 receives the connection feedback information sent by the charging device 12.

[0122] Further, after the battery system 111 receives the connection feedback information sent by the charging device 12, it can continue to execute:

[0123] In step S513, the battery system 111 disconnects the auxiliary circuit of the target battery.

[0124] In step S514, the battery system 111 waits for a predetermined duration.

[0125] Among them, the predetermined duration can be a value set according to the actual situation. For example, the predetermined duration can be 300 ms (milliseconds), 500 ms, or 1 s (second), etc.

[0126] In step S515, the battery system 111 closes the main circuit and sends a charging demand message to the charging device 12. Correspondingly, the charging device 12 receives the charging demand message sent by the battery system 111.

[0127] In step S523, after the charging device 12 receives the charging demand message, it charges according to the charging demand in the charging demand message.

[0128] Further, after the charging device 12 starts charging the battery system 111, the battery system 111 can continue to execute:

[0129] In step S516, the battery system 111 performs a charging end detection. If the charging end condition is met, step S517 is executed. If the charging end condition is not met, step S516 is executed.

[0130] In step S517, the battery system 111 sends a charging end request to the charging device 12, and the corresponding charging device 12 receives the charging end request sent by the battery system 111.

[0131] In step S524, the charging device 12 ends charging the target battery.

[0132] It should be noted that, in another case, if the charging requirement information further includes a charging time requirement, the charging device 12 can control the stop of charging according to the charging duration corresponding to the charging time requirement or the charging termination moment.

[0133] Therefore, in the embodiment of the present application, after receiving the connection feedback information sent by the charging device, the battery system can actively disconnect the auxiliary circuit, so that during the process of the charging device charging the target battery, the auxiliary circuit in the target battery always remains disconnected.
