[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Figure 1This illustration shows a battery storage information management method according to an embodiment of the present invention, used for managing battery storage information of a vehicle battery, the method comprising:

[0059] S100. When the set storage conditions are met, the battery storage information is simultaneously stored in the first internal storage unit and the second internal storage unit of the internal storage device; and / or

[0060] The battery storage information is stored in a first external storage unit and / or a second external storage unit of an external storage device;

[0061] S200: Read the battery storage information from at least one of the following storage units: a first internal storage unit, a second internal storage unit, a first external storage unit, and a second external storage unit;

[0062] The battery storage information includes multiple categories of battery storage information.

[0063] In other words, battery storage information is stored using a tiered, multi-backup approach. Specifically, a dedicated space for storing battery storage information, known as an internal storage device, can be allocated on the controller's main MCU (Microcontroller Unit) chip. This internal storage device includes a first internal storage unit and a second internal storage unit. During controller design, a chip for storing critical battery operation information can be selected as the external storage device, which also includes a first external storage unit and a second external storage unit. All battery storage information is stored in both the first and second internal storage units when certain conditions are met, effectively performing dual-backup storage on the internal storage device. Under certain conditions, based on the ease of recovery after information loss, certain categories of critical information can be selectively stored in either the first or second external storage unit, making efficient use of storage space.

[0064] Finally, the required information is read from the first internal storage unit, the second internal storage unit, the first external storage unit, and the second external storage unit for refined management of the power battery.

[0065] Therefore, the battery storage information management method according to the present invention, by reasonably setting storage conditions and making reasonable use of storage space, facilitates the storage of key information during the entire life cycle of the power battery, and enables refined management of the power battery even after the performance of the power battery deteriorates.

[0066] Optionally, the battery storage information includes a first type of information, a second type of information, and a third type of information.

[0067] Specifically, the first type of information is information related to battery safety, and once the first type of information is lost, it cannot be recovered by the battery or battery management system on its own.

[0068] The second type of information is related to battery performance. If the second type of information is lost, it can be recovered by verifying it after the battery or battery management system has been running for a set period of time.

[0069] The third type of information is information related to battery performance. If the third type of information is lost, it can be recovered by verifying it after the battery or battery management system is run.

[0070] Furthermore, the first type of information includes: cumulative charging capacity, cumulative discharging capacity, and cumulative running time, etc.; the second type of information includes: battery aging status, battery model internal resistance parameters, battery model capacity parameters, and self-learning parameters of remaining charging time, etc.; the third type of information includes: battery state of charge, battery fault status, and battery power boundary coefficient, etc.

[0071] In other words, the first type of information cannot be recovered by the power battery or battery management system alone after it is lost, and this information needs to be backed up and stored multiple times. The second type of information can be gradually recovered after the power battery or battery management system has been running for a long time. This type of information can be backed up appropriately. The third type of information can be immediately re-verified and recovered after the power battery or battery management system has been running. It should be noted that the performance deviation of the power battery caused by re-verification and recovery is generally less than 5%.

[0072] Preferably, the set storage conditions include: a first condition, a second condition, and a third condition;

[0073] The first condition is: when the vehicle containing the battery is in a low-voltage power-off state; or when a set time interval is reached; or when the vehicle speed containing the battery is greater than a set speed and the battery's state of charge change ratio reaches a set ratio.

[0074] The second condition is: when the vehicle containing the battery is in a low-voltage power-off state; or when a set time interval is reached;

[0075] The third condition is: when the speed of the vehicle where the battery is located is greater than the set speed and the change ratio of the state of charge of the battery reaches the set ratio.

[0076] In other words, the first condition is power-down triggering, periodic triggering, or event triggering; the second condition is power-down triggering or periodic triggering; and the third condition is event triggering. Periodic triggering can be set to store information every 5 minutes, and event triggering can be set to trigger when the vehicle speed is greater than 10 km / h and the SOC (State of Charge) change rate reaches 0.5%.

[0077] According to an embodiment of the present invention, step S100 includes:

[0078] When the first condition is met, the first type of information, the second type of information and the third type of information are simultaneously stored in the first internal storage unit and the second internal storage unit of the internal storage device.

[0079] When the second condition is met, the first type of information and the second type of information are stored simultaneously in the first external storage unit.

[0080] When the third condition is met, the first type of information is stored in the second external storage unit.

[0081] Specifically, such as Figure 2 As shown, when one of the following conditions is met—power-down trigger, periodic trigger, or event trigger—all three types of information (Type 1, Type 2, and Type 3) are stored in a dual-backup configuration within the internal storage device. Figure 3 As shown, when either power-down triggering or periodic triggering is met, the first type of information and the second type of information are backed up in the external storage device, that is, stored in the first external storage unit respectively. Figure 4 As shown, when the event is triggered, only the first type of information is backed up in the second external storage unit.

[0082] According to another embodiment of the present invention, step S200 includes:

[0083] Read information from the first internal storage unit and the second internal storage unit and verify whether the information is normal;

[0084] If, after verification, one of the information read from the first internal storage unit and the second internal storage unit is normal information and the other is abnormal information, then the normal information read from the first internal storage unit or the second internal storage unit shall be used as the target information for battery management.

[0085] If the information read from the first internal storage unit and the second internal storage unit is verified to be normal, then verify whether the information read from the first internal storage unit and the second internal storage unit is consistent.

[0086] If the information read from the first internal storage unit and the second internal storage unit is verified to be normal and consistent, then the information read from the first internal storage unit shall be used as the target information for battery management.

[0087] If the information read from the first internal storage unit and the second internal storage unit is verified to be normal and inconsistent, or if the information read from the first internal storage unit and the second internal storage unit is verified to be abnormal, then:

[0088] For the first type of information:

[0089] Read information from the first external storage unit and verify whether the information is normal; if so, use the information read from the first external storage unit as the target information for battery management; otherwise, read information from the second external storage unit and verify whether the information is normal; if so, use the information read from the second external storage unit as the target information for battery management; otherwise, report a fault.

[0090] And / or, for the second type of information:

[0091] Information is read from the first external storage unit and verified to be normal. If it is, the information read from the first external storage unit is used as the target information for battery management. Otherwise, the current real-time information of the battery is collected and the current real-time information is verified for a set duration. After the verification is passed, the current real-time information is used as the target information for battery management.

[0092] And / or, for the third type of information:

[0093] Collect the current real-time information of the battery and verify the current real-time information. If the verification is successful, the current real-time information is used as the target information for battery management.

[0094] Specifically, such as Figure 5 As shown, the reading mechanism for the first type of information is as follows:

[0095] When the information read from the first internal storage unit is verified to be normal and the information read from the second internal storage unit is verified to be normal: (1) If the information read from the first internal storage unit is consistent with the information read from the second internal storage unit, the information read from the first internal storage unit is used for refined management of the power battery. (2) If the information read from the first internal storage unit is inconsistent with the information read from the second internal storage unit: a. When the information read from the first external storage unit is verified to be normal, the information read from the first external storage unit is used for refined management of the power battery; b. When the information read from the first external storage unit is verified to be abnormal: when the information read from the second external storage unit is verified to be normal, the information read from the second external storage unit is used for refined management of the power battery; when the information read from the second external storage unit is verified to be abnormal, the fault is reported and after-sales service is provided.

[0096] When the information read from the first internal storage unit is verified to be normal, but the information read from the second internal storage unit is verified to be abnormal, the information read from the first internal storage unit is used for refined management of the power battery.

[0097] When the information read from the first internal storage unit fails verification but the information read from the second internal storage unit passes verification, the information read from the second internal storage unit is used for refined management of the power battery.

[0098] When the information read from the first internal storage unit fails verification and the information read from the second internal storage unit fails verification: (1) When the information read from the first external storage unit fails verification, the information read from the first external storage unit is used for refined management of the power battery. (2) When the information read from the first external storage unit fails verification: When the information read from the second external storage unit fails verification, the information read from the second external storage unit is used for refined management of the power battery; when the information read from the second external storage unit fails verification, the fault is reported and after-sales service is provided.

[0099] like Figure 6 As shown, the mechanism for reading the second type of information is as follows:

[0100] When the information read from the first internal storage unit is verified normally and the information read from the second internal storage unit is verified normally: (1) If the information read from the first internal storage unit is consistent with the information read from the second internal storage unit, the information read from the first internal storage unit is used for refined management of the power battery. (2) If the information read from the first internal storage unit is inconsistent with the information read from the second internal storage unit: When the information read from the first external storage unit is verified normally, the information read from the first external storage unit is used for refined management of the power battery; when the information read from the first external storage unit is verified abnormally, the current real-time information of the power battery is used for re-verification, and the second type of information is verified after long-term operation.

[0101] When the information read from the first internal storage unit is verified to be normal, but the information read from the second internal storage unit is verified to be abnormal, the information read from the first internal storage unit is used for refined management of the power battery.

[0102] When the information read from the first internal storage unit fails verification but the information read from the second internal storage unit passes verification, the information read from the second internal storage unit is used for refined management of the power battery.

[0103] When the information read from the first internal storage unit fails verification and the information read from the second internal storage unit fails verification: when the information read from the first external storage unit fails verification, the information read from the first external storage unit is used for refined management of the power battery; when the information read from the first external storage unit fails verification, the current real-time information of the power battery is used for re-verification, and the second type of information is verified after a long period of operation.

[0104] like Figure 7 As shown, the mechanism for reading the third type of information is as follows:

[0105] When the information read from the first internal storage unit is verified to be normal and the information read from the second internal storage unit is verified to be normal: if the information read from the first internal storage unit is consistent with the information read from the second internal storage unit, then the information read from the first internal storage unit is used for refined management of the power battery; if the information read from the first internal storage unit is inconsistent with the information read from the second internal storage unit, then the current real-time information of the power battery is used to re-verify the third type of information.

[0106] When the information read from the first internal storage unit is verified to be normal, but the information read from the second internal storage unit is verified to be abnormal, the information read from the first internal storage unit is used for refined management of the power battery.

[0107] When the information read from the first internal storage unit fails verification but the information read from the second internal storage unit passes verification, the information read from the second internal storage unit is used for refined management of the power battery.

[0108] If the information read from the first internal storage unit fails verification and the information read from the second internal storage unit fails verification, the third type of information is re-verified using the current real-time information of the power battery.

[0109] This invention also provides a battery storage information management device 100, such as... Figure 8 As shown, it includes:

[0130] If the information read from the first internal storage unit and the second internal storage unit is verified to be normal and consistent, then the information read from the first internal storage unit shall be used as the target information for battery management.

[0131] If the information read from the first internal storage unit and the second internal storage unit is verified to be normal and inconsistent, or if the information read from the first internal storage unit and the second internal storage unit is verified to be abnormal, then:
