Description

Technical Field

[0001] The present invention belongs to the technical field of automobile battery swap stations, and in particular relates to a method for handling faults in battery swap stations. Background Art

[0002] The battery swap station is an energy station that provides battery replacement for new energy vehicles. It mainly includes a battery swap platform, an RGV running cart, a stacker and a battery compartment. Among them, the battery swap platform includes a centering unit, and the RGV running cart is provided with a lifting unit and an unlocking unit. When the new energy vehicle is replacing the battery, the vehicle drives onto the battery swap platform, the centering unit centers the vehicle, the RGV running cart runs to the vehicle battery, and the battery on the vehicle is unloaded through the cooperation of the lifting unit and the unlocking unit. Then, the RGV running cart runs to the stacker, and the stacker takes the battery on the RGV cart and puts it into the charging position on the battery compartment for charging. Then, the fully charged battery in the battery compartment is taken out and put back on the RGV running cart. The RGV running cart drives the battery to the vehicle to install the battery, thus completing a vehicle battery swap.

[0003] At present, various faults often occur during the operation of battery swap stations due to equipment aging, improper operation or external factors, affecting the normal operation of the station. Traditional fault handling methods mostly rely on manual troubleshooting and repair, which is not only inefficient but also increases operating costs.

[0004] In the prior art, the patent with publication number CN117769686A discloses a method, device, computer equipment and storage medium for controlling the operation of a battery swap station, which can obtain the first operating parameter to detect whether each battery swap station equipment in the battery swap station has a fault. When there is a faulty device, the faulty device is first controlled to restart through a restart instruction to try to see if the fault of the faulty device can be eliminated by restarting. If the second operating parameter analysis of the faulty device after restart shows that the restart can eliminate the fault, it is only necessary to continue to control the operation of the faulty device. If the result is that the restart cannot eliminate the fault, then the maintenance-related processing is performed. Avoid the battery swap station equipment waiting for maintenance, resulting in a long waiting time.

[0005] In actual use, some fault problems can be effectively solved by restarting the equipment of each unit. However, for the process in which the stacker cannot pick up and place normally due to battery compartment failure, if restarting this step cannot solve the problem, it will only report an error and wait for maintenance without a clear solution. Summary of the invention

[0006] The purpose of the present invention is to provide a method for handling faults in a battery swap station to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above purpose, a technical solution adopted by the present invention is: a method for handling faults in a battery swap station, which is applied to a battery swap station system with a battery swap platform, an RGV trolley, a palletizer and a battery compartment, wherein a battery placement position is provided in the battery compartment, and at least two fully charged batteries are included in the battery compartment, and specifically comprises the following steps:

[0008] S1: The palletizer removes the battery from the RGV trolley and puts it into the battery placement position;

[0009] S2: The palletizer moves to a fully-charged battery to pick up the battery. If the battery cannot be picked up and still cannot be picked up after restarting the relevant equipment, the palletizer moves to another fully-charged battery to pick up the fully-charged battery.

[0010] Preferably, the battery swap station system further comprises an operation data monitoring and processing unit, which monitors the operation data of each part of the battery swap station system and performs maintenance processing. The maintenance processing method is as follows:

[0011] S01: judging whether each part of the battery swap station system is operating normally according to the operating data; if not, restoring the part to the initial working state and re-operating the part;

[0012] S02: includes two conditions. When any one of the conditions is met, the battery swap station system is restarted to restore all parts to the initial state before the battery swap:

[0013] Condition 1: After the abnormal part is re-run in step S01, the abnormal part still cannot run normally;

[0014] Condition 2: The palletizer cannot successfully pick up the battery after running to other fully charged batteries;

[0015] In step S2, before the palletizer moves to the next fully-charged battery to pick up the fully-charged battery, the palletizer is also inspected and processed by the operation data monitoring and processing unit.

[0016] Preferably, after the battery swap station system is restarted in step S02, if there are still parts of the battery swap station system that are not operating normally, any of the following execution situations may occur:

[0017] (1) If the RGV car does not remove the vehicle battery, the battery swap platform unlocks the vehicle so that the driver can drive away from the battery swap station;

[0018] (2) If the RGV has removed the vehicle battery, the battery must be reinstalled into the vehicle through the RGV. At the same time, the battery swap platform unlocks the vehicle so that the driver can drive away from the battery swap station;

[0019] (3) If the RGV is unable to load the battery into the vehicle or the battery swap platform is unable to unlock the vehicle, the driver abandons the vehicle and leaves the battery swap station.

[0020] Preferably, in step S2, the number of times the palletizer switches to other fully-charged batteries is n, where n≤the number of fully-charged batteries in the battery compartment.

[0021] Preferably, in condition 2 of S02, after the palletizer runs to other fully charged batteries, if the battery cannot be taken out, the part needs to be restored to the initial working state and re-run to take out the battery again. If the battery still cannot be taken out, the battery swap station system is restarted.

[0022] Preferably, the battery swap station system further includes a feedback system and a monitoring center, wherein the feedback system feeds back the battery swap station fault information to the monitoring center, and the monitoring center dispatches professionals to provide remote guidance or on-site processing.

[0023] Beneficial effects of the present invention: The present invention is designed to move to other fully charged batteries in the battery compartment to pick up batteries when the palletizer cannot pick up the fully charged batteries on the first running route, which is equivalent to performing a fault monitoring on the fully charged batteries that cannot be picked up, that is, if the palletizer can pick up the batteries at other fully charged batteries, the position where the batteries cannot be picked up may be faulty. If the palletizer cannot pick up other batteries, it may be that the palletizer has a fault. The method of this solution can relatively effectively determine the cause of the fault, spend one more operating time of the palletizer, and also ensure the overall efficiency of battery replacement, avoiding the inability to replace batteries due to the problem of fully charged batteries that cannot be picked up, and ensuring the time benefits of customers.

[0024] Restarting the entire battery swap station system is equivalent to an overhaul of the operating process. If the overhaul is successful, the result of the battery swap can be effectively guaranteed. If the battery swap still cannot be performed, it may be a hardware failure. The cause of the failure can be relatively determined based on which part of the failure occurs.

[0025] Among them, if the battery swap station system is still operating abnormally after restarting, the interests of the driver will be prioritized to avoid vehicle damage caused by problems with the battery swap station equipment, or loss of time and benefits caused by waiting for repairs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a work flow chart of the present invention;

[0027] Figure 2 This is the execution process after restarting the battery swap station system in the present invention. DETAILED DESCRIPTION

[0028] 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.

[0029] Example:

[0030] See also Figure 1 A method for handling faults in a battery swap station is provided, which is used in a battery swap station system with a battery swap platform, an RGV trolley, a palletizer, a battery compartment and an operation data monitoring and processing unit. The operation data monitoring and processing unit monitors the operation data of each part of the battery swap station system and performs maintenance processing. A battery placement position is provided in the battery compartment, and at least two fully charged batteries are included in the battery compartment. Specifically, the method comprises the following steps:

[0031] S1: The palletizer removes the battery from the RGV trolley and places it in the battery placement position for processing;

[0032] S2: The palletizer moves to a fully-charged battery to pick up the battery. If the battery cannot be picked up and the battery is still not picked up after restarting the relevant equipment, the palletizer moves to another fully-charged battery to pick up the fully-charged battery.

[0033] Specifically, it can be assumed that there are 8 positions for fully charged batteries in the charging warehouse, and the 8 positions are arranged as a whole of four groups in the upper and lower layers. The battery placement position can be the position, and the position can also be a place where the battery can be charged. When the battery is in the position, it is in the charging state. The situations in which the palletizer cannot take the fully charged battery include but are not limited to the following: 1. The water and electricity plugs of the position cannot be lifted, resulting in the fully charged battery being unable to leave the position; 2. The in-place sensor is abnormal, which is manifested as the palletizer reaches the predetermined position, the palletizer's fork extends under the fully charged battery, but the in-place sensor does not detect the fork, so the fork cannot perform the next lifting action, so the fully charged battery cannot be taken; 3. The palletizer is physically damaged;

[0034] During operation, the number of times n that the palletizer switches to other fully-charged batteries can be limited. For example, if n is limited to 3, the palletizer can try to take three fully-charged batteries in total.

[0035] In step S2, before the palletizer moves to the next fully-charged battery to pick up the fully-charged battery, the palletizer is also inspected and processed by the operation data monitoring and processing unit. The inspection and processing method is as follows:

[0036] S01: judging whether each part of the battery swap station system is operating normally according to the operating data; if not, restoring the part to the initial working state and re-operating the part;

[0037] S02: includes two conditions. When at least one of the conditions is met, the battery swap station system is restarted to restore all parts to the initial state before the battery swap:

[0038] Condition 1: Re-run the abnormal part in step S01, and the abnormal part still cannot run normally;

[0039] Condition 2: The palletizer cannot successfully pick up the battery after running to other fully charged batteries.

[0040] Among them, the abnormalities of other systems include: when the centering unit detects that the tire centering torque does not meet the specified torque, the centering unit is released and the centering operation is performed again; when the RGV is accelerating and unlocking the vehicle, a fault occurs and the acceleration and unlocking operation is performed again; the battery compartment cannot be opened; the palletizer cannot take the battery on the RGV cart, etc. Various mechanisms involved in the battery replacement process.

[0041] Among them, in condition 2 of S02, after the palletizer runs to other fully charged batteries, if the battery cannot be taken out, the part must be restored to the initial working state and re-run to take out the battery again. If the battery still cannot be taken out, the battery swap station system must be restarted.

[0042] Among them, after the battery swap station system is restarted in step S02, if there are still abnormal operating parts in the battery swap station system, any of the following execution situations may occur:

[0043] (1) If the RGV car does not remove the vehicle battery, the battery swap platform unlocks the vehicle so that the driver can drive away from the battery swap station;

[0044] (2) If the RGV has removed the vehicle battery, the battery must be reinstalled into the vehicle through the RGV. At the same time, the battery swap platform unlocks the vehicle so that the driver can drive away from the battery swap station;

[0045] (3) If the RGV is unable to load the battery into the vehicle or the battery swap platform is unable to unlock the vehicle, the driver abandons the vehicle and leaves the battery swap station.

[0046] In addition, the battery swap station system also includes a feedback system and a monitoring center. The feedback system feeds back the battery swap station failure information to the monitoring center, and the monitoring center sends professionals to provide remote guidance or on-site processing.

[0047] 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.
