Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicle battery swap stations, and in particular relates to a fault warning method for a new energy vehicle battery swap station. Background Art

[0002] During the use of battery swap stations, the main systems involved include the battery swap station system and the vehicle system. With the widespread promotion of unmanned battery swap stations, the reduction of battery swap failure rate has become a key factor in whether unmanned operation can be implemented. In conventional unmanned battery swap stations, fault monitoring and maintenance are carried out on various components of the battery swap station system, while the detection and early warning of faults in the vehicle system itself are ignored.

[0003] In fact, some faults are caused by the vehicle itself, the battery itself, or the matching problems between the vehicle and the battery. In this case, the battery replacement cannot be completed, which affects the efficiency of the battery replacement.

[0004] This application is an early warning solution designed by the inventor with vehicle systems as the main target. Summary of the invention

[0005] The purpose of the present invention is to provide a fault warning method for a new energy vehicle battery swap station to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, a technical solution adopted by the present invention is: a fault warning method for a new energy vehicle battery swap station, including a data center monitoring system, specifically comprising the following steps:

[0007] S1: Identify and upload the vehicle's unique identification code to the data center monitoring system;

[0008] S2: Identify and upload the unique identification code of the used battery pack at the battery swap station to the data center monitoring system. The used battery pack refers to the battery pack removed from the vehicle;

[0009] S3: Identify and upload the unique identification code of the battery pack to be used in the battery swap station to the data center monitoring system. The battery pack to be used refers to the battery pack to be installed on the vehicle;

[0010] S4: confirming and uploading the bolt locking and unlocking data of the battery pack used or to be used in the vehicle during the battery replacement process to the data center monitoring system, wherein the bolt locking and unlocking data includes at least one of the number of locking turns, locking torque, number of cap recognition times and number of unlocking times;

[0011] S5: Setting standard values ​​for the number of locking turns, locking torque, cap recognition times and unlocking times, making an early warning record when any value of the number of locking turns or locking torque of the used battery pack or the battery pack to be used is less than the standard value, and making an early warning record when any value of the number of cap recognition times and unlocking times of the used battery pack or the battery pack to be used is less than the standard value;

[0012] S6: In step S5, when the number of times any numerical value is recorded is greater than the alarm setting number n, an alarm is issued. At this time, the used battery pack or the battery pack to be used needs to be checked, and n≥2.

[0013] Preferably, if the number of consecutive or intermittent warning records for the same vehicle is greater than the alarm setting number n, an alarm is issued. At this time, the vehicle nuts need to be checked, and the interval value for obtaining the warning record is set to m, where m≤5.

[0014] Preferably, when the same fault warning record appears k times consecutively or the alarm appears k times consecutively at the same battery swap station, it is necessary to inspect the relevant institutions involved in the battery swap station failure, where k≥2.

[0015] Preferably, in step S4, alarm values ​​for the number of locking turns, locking torque, cap recognition times and unlocking times are set, the number of locking turns of the alarm value is smaller than the number of locking turns during the early warning record, the locking torque of the alarm value is smaller than the locking torque during the early warning record, the alarm values ​​of the cap recognition times or the unlocking times are both smaller than the times during the early warning record, and an alarm is issued when any of the locking turns, locking torque, cap recognition times and unlocking times reaches the alarm value.

[0016] Preferably, different fault code numbers are assigned to various mechanisms of the battery swap station.

[0017] Beneficial effects of the present invention: The present invention checks the data of the battery pack, thereby making up for the shortcoming of the existing battery swap station system that only performs fault detection on various mechanisms of the battery swap station, and serves as an early warning of possible faults of the battery pack, effectively ensuring the safety of vehicle use;

[0018] Among them, by monitoring the number of warning records and the continuity relationship of the same vehicle, the fault detection of the vehicle nut can be further realized, further enhancing the safety of vehicle use;

[0019] Among them, by paying attention to the number of warning records and continuity of the same fault at the battery swap station, the fault detection of the battery swap station system can be further realized, further enhancing the safety of vehicle use;

[0020] Among them, by setting the alarm value, the safety of vehicle use can be further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] Example:

[0024] See also Figure 1 A fault warning method for a new energy vehicle battery swap station, a fault warning method for a new energy vehicle battery swap station, including a data center monitoring system, specifically including the following steps:

[0025] S1: Identify and upload the vehicle's unique identification code to the data center monitoring system;

[0026] S2: Identify and upload the unique identification code of the used battery pack at the battery swap station to the data center monitoring system. The used battery pack refers to the battery pack removed from the vehicle;

[0027] S3: Identify and upload the unique identification code of the battery pack to be used in the battery swap station to the data center monitoring system. The battery pack to be used refers to the battery pack to be installed on the vehicle;

[0028] S4: confirming and uploading the bolt locking and unlocking data of the battery pack used or to be used in the vehicle during the battery replacement process to the data center monitoring system, wherein the bolt locking and unlocking data includes at least one of the number of locking turns, locking torque, number of cap recognition times and number of unlocking times;

[0029] S5: Setting standard values ​​for the number of locking turns, locking torque, cap recognition times and unlocking times, making an early warning record when any value of the number of locking turns or locking torque of the used battery pack or the battery pack to be used is less than the standard value, and making an early warning record when any value of the number of cap recognition times and unlocking times of the used battery pack or the battery pack to be used is less than the standard value;

[0030] S6: In step S5, when the number of times any numerical value is recorded is greater than the alarm setting number n, an alarm is issued. At this time, the used battery pack or the battery pack to be used needs to be checked, and n≥2.

[0031] In the above content, the number of locking turns refers to the number of rotational engagement turns between the battery pack bolt and the vehicle nut, which needs to be determined in combination with the locking and unlocking mechanism of the battery swap station. Specifically, the locking and unlocking mechanism controls the bolt and nut to abut against each other. When the feedback pressure is reduced to the standard, it means that the threads between the two have abutted against each other. At this time, when the locking and unlocking mechanism controls the bolt to rotate until the feedback torque (i.e., locking torque) meets the standard, the current number of locking turns can be determined. Long-term use will cause thread wear, which will reduce the connection force between the bolt and nut. This is why this solution focuses on the data of the number of locking turns and rotational torque;

[0032] Among them, the number of cap recognitions refers to the situation of the locking of the unlocking gun and the bolts and nuts. In general scenarios, the cap recognition only needs to be performed once. In order to ensure the success rate of battery replacement, if the system fails to recognize the cap for the first time, it will automatically perform the recognition twice or more times. The number of cap recognitions for battery replacement needs to be counted in the battery replacement results. If the system performs the recognition twice or more times, it means that there is a hidden danger in the bolt / gun head, and the problem analysis mechanism will be triggered at this time;

[0033] Among them, the number of unlocking times refers to the unlocking of the bolts by adding an unlocking gun. In general scenarios, unlocking only needs to be performed once. However, due to the characteristics of vehicle bolts, the bolts and nuts may rust due to the vehicle wading through water, or the vehicle may not have been replaced for a long time and the tightening force of the bolts and nuts may be large. Therefore, this data is also the project that this plan focuses on.

[0034] Among them, if the number of consecutive or intermittent warning records for the same vehicle is greater than the alarm setting number n, an alarm will be issued. At this time, the vehicle nuts need to be checked, and the interval value for obtaining the warning record is set to m, where m≤5.

[0035] Among them, when the same fault warning record appears k times in succession at the same battery swap station or the alarm appears k times in succession, it is necessary to inspect the relevant institutions involved in the battery swap station failure, where k≥2.

[0036] Among them, in step S4, alarm values ​​of the number of locking turns, locking torque, cap recognition times and unlocking times are set, the number of locking turns of the alarm value is less than the number of locking turns during the early warning record, the locking torque of the alarm value is less than the locking torque during the early warning record, the alarm values ​​of the cap recognition times or the unlocking times are both less than the times during the early warning record, and an alarm is issued when any of the locking turns, locking torque, cap recognition times and unlocking times reaches the alarm value.

[0037] Among them, different fault code numbers are assigned to each mechanism of the battery swap station to facilitate the identification of the mechanism that needs to be repaired.

[0038] Working process and principle:

[0039] The present invention performs fault warning on vehicles, battery packs and battery swap station systems by monitoring the data of battery pack bolts, the number of warning records and continuity relationship of the same vehicle, and the number of warning records and continuity relationship of the same fault at the battery swap station, thereby improving the problem of insufficient fault warning capability of existing battery swap stations. Staff can be systematically arranged to inspect and repair relevant vehicles and related equipment of battery swap stations in advance, thereby further improving the unmanned level of battery swap stations and reducing labor costs.

[0040] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
