[0045] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0046] Considering that in the prior art, when replacing the original battery management system with a new battery management system, if the power battery attenuation related information is read from the original battery management system, then when the original battery management system is damaged and cannot read the information, the prior art cannot configure the new battery management system. Based on this, the embodiments of the present application provide an information management method and system, which are described below through embodiments.

[0047] To facilitate understanding of this embodiment, an information management method disclosed in the embodiment of this application is first introduced in detail. The method is applied to an information management system on a new energy electric vehicle, and the information management system includes a first battery management system, a gateway, and an on-board data transmission module that are interconnected; the on-board data transmission module is also connected to a big data module outside the new energy electric vehicle.

[0048] like Figure 1 As shown, the following steps S101-S103 are included:

[0049] S101: The first battery management system synchronizes the power battery attenuation related information of the power battery on the new energy electric vehicle to the big data module through the on-board data transmission module, so that the big data module stores the power battery attenuation related information in a separate database corresponding to the new energy electric vehicle.

[0050] In this embodiment, the first battery management system stores the latest power battery attenuation-related information of the power battery, wherein the power battery attenuation-related information includes information such as the power battery service life, usage time, and charge and discharge times.

[0051] like Figure 2 As shown, during the use of the power battery, when the power battery attenuation related information is updated, the first battery management system sends the updated power battery attenuation related information to the vehicle data transmission module, and the vehicle data transmission module forwards the power battery attenuation related information to the big data module.

[0052] Among them, the big data module is a module set outside the new energy electric vehicle, and the big data module stores the power battery attenuation related information of multiple new energy electric vehicles. When the big data module stores the power battery attenuation related information of each new energy electric vehicle, specifically in the big data module, for each new energy electric vehicle, according to the national standard code of the power battery in the new energy electric vehicle, a separate database corresponding to the new energy electric vehicle is established, and then the power battery attenuation related information of the new energy electric vehicle is stored in the separate database corresponding to the new energy electric vehicle.

[0053] Since the national standard code of each power battery is unique, the separate database corresponding to each new energy electric vehicle is also unique.

[0054] S102: When the first battery management system currently in use is replaced with the second battery management system, if the gateway receives a configuration instruction sent by a diagnostic configuration module outside the new energy electric vehicle, the gateway obtains the power battery attenuation-related information of the new energy electric vehicle from the big data module through the on-board data transmission module, and sends the power battery attenuation-related information to the diagnostic configuration module.

[0055] In this embodiment, when the first battery management system needs to be replaced due to damage, aging, etc., the first battery management system in the new energy electric vehicle is replaced with a second battery management system, where the second battery management system can be a new battery management system.

[0056] After the first battery management system is replaced with the second battery management system, it is necessary to configure the power battery attenuation related information of the power battery in the second battery management system so that the second battery management system can replace the first battery management system to perform subsequent work.

[0057] In this embodiment, when configuring the power battery attenuation related information of the power battery in the second battery management system, a diagnostic configuration module outside the new energy electric vehicle is used to connect the gateway in the new energy electric vehicle, wherein the diagnostic configuration module can be a module used by a repair shop to diagnose new energy electric vehicles.

[0058] The diagnostic configuration module sends configuration instructions to the gateway, and the gateway sends the configuration instructions to the big data module through the on-board data transmission module. The big data module transmits the power battery attenuation information stored in itself to the diagnostic configuration module through the on-board data transmission module and the gateway according to the configuration instructions.

[0059] S103: The second battery management system receives the power battery attenuation related information sent by the diagnosis configuration module through the gateway, configures the power battery attenuation related information, and uses the second battery management system as a new first battery management system.

[0060] In this embodiment, the gateway sends the acquired information related to the power battery attenuation to the diagnostic configuration module. After the diagnostic configuration module configures the information related to the power battery attenuation into the second battery management system, the second battery management system can serve as a new first battery management system to replace the original first battery management system.

[0061] In a possible implementation, Figure 3 As shown, the information management system also includes a vehicle control module; the vehicle control module is connected to the first battery management system; the method can also be performed according to the following steps S201-S204:

[0062] S201: The first battery management system collects power battery status information of the power battery.

[0063] In this embodiment, the power battery status information includes any one or more of the following information: battery temperature, battery current, voltage of each battery cell, atmospheric pressure in the power battery (the power battery is a sealed shell. When the battery has thermal runaway, harmful gases will be ejected, which will increase the internal pressure of the power battery pack), power battery smoke concentration, insulation resistance (the positive and negative electrodes of the power battery should be insulated from the power battery shell. If the insulator ages, the insulation resistance between the positive or negative electrode of the power battery and the power battery shell will decrease), and charging mode (including AC charging and DC charging).

[0064] like Figure 4 As shown, when the first battery management system collects the power battery status information of the power battery, specifically: the sensor module collects: battery current, atmospheric pressure in the power battery, power battery smoke concentration; the collection module collects: battery temperature, voltage of each battery cell, insulation resistance, and charging mode.

[0065] S202: For each first fault, the first battery management system analyzes first fault information of the first fault according to the power battery status information; the first fault information includes whether the first fault occurs and the fault level when the first fault occurs; the first fault is determined based on the computing power of the first battery management system.

[0066] In this embodiment, the computing power of the first battery management system is limited, and therefore, it is impossible to analyze all faults. The first battery management system can only analyze the first fault within the scope of its computing power.

[0067] S203: When the first fault occurs, the first battery management system sends the fault level of the first fault to the vehicle control module.

[0068] S204: The vehicle control module determines a response measure for the fault level based on the fault level of the first fault, and executes the response measure.

[0069] Exemplarily, when the first fault is that the power battery temperature is too high, the response measure for this fault level may be to stop charging the power battery. At this time, the vehicle control module may execute this response measure.

[0070] In a possible implementation manner, the method may also be performed according to the following steps S301-S304:

[0071] S301: For each first fault, when the first fault occurs, the first battery management system sends the first fault information of the first fault to the big data module through the on-board data transmission module, so that the big data module stores each first fault information in a separate database corresponding to the new energy electric vehicle.

[0072] S302: The first battery management system sends the power battery safety-related information in the power battery status information to the big data module through the on-board data transmission module, so that the big data module analyzes the second fault information of the second fault according to the power battery safety-related information for each second fault, and stores each second fault information in a separate database corresponding to the new energy electric vehicle; wherein the second fault is determined based on the computing power of the big data module; the computing power of the big data module is greater than the computing power of the first battery management system.

[0073] In this embodiment, the power battery safety related information is at least part of the power battery status information, and the power battery safety related information may be specified according to a specific application scenario.

[0074] Generally, the computing power of the big data module is greater than that of the first battery management system. Therefore, the second fault that can be analyzed by the big data module is generally not able to be analyzed by the first battery management system. In this embodiment, the first fault and the second fault are different faults.

[0075] In this embodiment, the order between step S301 and step S302 is not specified. Step S301 may be executed first and then step S302, or step S302 may be executed first and then step S301, or they may be executed simultaneously.

[0076] S303: If the gateway receives the fault information acquisition instruction sent by the diagnosis configuration module, the gateway acquires the first fault information and the second fault information from the big data module through the vehicle data transmission module.

[0077] In this embodiment, when maintenance personnel need to perform maintenance and inspection on the new energy electric vehicle, the maintenance personnel connect the diagnostic configuration module to the gateway, such as Figure 3 As shown, the diagnostic configuration module sends a fault information acquisition instruction to the gateway, and the gateway forwards the fault information acquisition instruction to the big data module through the on-board data transmission module. The big data module returns the first fault information and the second fault information of the new energy electric vehicle to the gateway through the on-board data transmission module.

[0078] S304: The gateway sends the acquired first fault information and second fault information to the diagnosis configuration module, so that a display screen of the diagnosis configuration module displays the first fault information and the second fault information to the maintenance personnel.

[0079] Through the above method, maintenance personnel can know the fault information of the new energy electric vehicle, which is convenient for maintenance personnel to perform vehicle maintenance on the new energy electric vehicle.

[0080] In a possible implementation manner, after the first battery management system sends the power battery safety related information in the power battery status information to the big data module through the vehicle-mounted data transmission module, the method may also be performed according to the following steps:

[0081] When the vehicle control module receives the warning information sent by the big data module through the on-board data transmission module and the first battery management system, it performs a fault warning based on the warning information; wherein, the warning information is judged by the big data module based on the fault development trend of the third fault; the fault development trend is obtained by the big data module through a fault analysis of the third fault based on the power battery safety-related information.

[0082] In this embodiment, after the first battery management system sends the power battery safety related information in the power battery status information to the big data module through the vehicle data transmission module, the big data module performs a fault analysis on the third fault according to the power battery safety related information for each third fault, and obtains the fault development trend of the third fault. The big data module sends the fault development trend to the vehicle control module through the vehicle data transmission module and the first battery management system in turn, and the vehicle control module performs a fault warning according to the warning information when receiving the warning information sent by the big data module.

[0083] For example, when the third fault is to detect the insulation resistance trend of the power battery, if the power battery has poor airtightness due to collisions and other reasons, water vapor enters the battery, etc., causing the insulation resistance of the power battery to continue to decrease, then the insulation resistance decrease trend can be used as a warning fault. Specifically, when the insulation resistance trend shows a decreasing trend, the vehicle control module can receive the warning information sent by the big data module that the insulation resistance trend shows a decreasing trend. At this time, the vehicle control module issues a fault warning to the driver based on the warning information.

[0084] Based on the same technical concept, the embodiment of the present application also provides an information management system, such as Figure 2 As shown, the information management system on the new energy electric vehicle includes a first battery management system, a gateway, and an on-board data transmission module that are interconnected; the on-board data transmission module is also communicatively connected with a big data module outside the new energy electric vehicle;

[0085] The first battery management system is used to synchronize the power battery attenuation related information of the power battery on the new energy electric vehicle to the big data module through the on-board data transmission module, so that the big data module stores the power battery attenuation related information in a separate database corresponding to the new energy electric vehicle;

[0086] The gateway is used for, when the first battery management system currently in use is replaced with the second battery management system, if a configuration instruction sent by the diagnosis configuration module outside the new energy electric vehicle is received, obtaining the power battery attenuation related information of the new energy electric vehicle from the big data module through the on-board data transmission module, so as to send the power battery attenuation related information to the diagnosis configuration module;
