Fig. 1 is a flowchart of a battery pack maintenance method according to an embodiment of the present invention, where this embodiment is applicable to a case of maintaining a battery pack, and typically, the method is applicable to a case of maintaining a battery pack in a power swapping station, and the method may be executed by a battery pack maintenance device, where the device may be implemented by software and/or hardware, and specifically includes the following steps:
s110, a maintenance request of a battery pack is obtained, wherein the battery pack comprises a battery pack on a vehicle in communication connection with a power exchanging station and a battery pack arranged in the power exchanging station.
The maintenance request of the battery pack may include a balance maintenance request and a State-of-Health (SOH) maintenance request. Specifically, when the voltage value of each battery cell in the battery pack collected by the battery management system does not match the reference performance parameter, the current battery pack needs to be balanced and maintained. When the actual performance parameters of the battery collected by the battery management system do not accord with the reference performance parameters, the performance of the current battery pack is reduced, and SOH maintenance is needed, namely, the battery pack is recalibrated.
For a battery pack in the battery replacement station or a battery pack on an electric automobile, endurance is reduced due to long-term use, so that performance parameters of the battery pack need to be detected, and the service life and the endurance of the battery are improved by performing corresponding maintenance operation on the battery pack in the battery replacement station.
Further referring to fig. 2, the battery swapping station in this embodiment includes a station-level monitoring system, a charging system, a battery swapping system, and a battery maintenance system, and the charging system, the point changing system, and the battery maintenance system are respectively connected to the station-level monitoring system. The station-level monitoring system is used for monitoring whether a battery pack on a vehicle in communication connection with the battery swapping station and a battery pack arranged in the battery swapping station have a maintenance request; the battery maintenance system is a bidirectional charger and is used for controlling the package to discharge when the battery package needs SOH maintenance, and after the discharge is finished, the battery is kept still for a period of time and recharged, so that the recalibration work of the battery is finished.
Specifically, when a vehicle drives into a battery replacement station, a vehicle-mounted terminal equipped on the vehicle can establish near field communication with the battery replacement station, and if a battery pack on the vehicle has a maintenance requirement, the station-level monitoring system acquires the maintenance requirement of the battery pack when the vehicle drives into the battery replacement station; when a battery pack in the battery swapping station has a maintenance request, a battery management system sends a maintenance request instruction to a station control host station-level monitoring system.
And S120, determining a target maintenance position of the battery pack in the power exchanging station according to the maintenance request, and controlling the battery pack to be conveyed to the target maintenance position for maintenance operation.
In this embodiment, different maintenance requests correspond to different maintenance positions in the battery swapping station, and specifically, if the maintenance request is balance maintenance, a common charging position in the battery swapping station is preferentially selected as a target maintenance position, and the battery pack is transported to the common charging position for balance maintenance; if the maintenance request is SOH maintenance, the battery pack needs to be transported to a designated maintenance position for maintenance operation, and the maintenance position is recalibrated through the battery pack of the bidirectional charger.
According to the technical scheme, the maintenance request of the battery pack on the vehicle in communication connection with the battery changing station and the maintenance request of the battery pack arranged in the battery changing station are obtained, the target maintenance bin of the battery pack in the battery changing station is determined according to the maintenance request, the battery pack is controlled to be carried to the target bin for maintenance operation, the battery pack is maintained in the battery changing station, and the service life of the battery is greatly prolonged.
Example two
Fig. 3 is a flowchart of a battery pack maintenance method according to a second embodiment of the present invention, where in the second embodiment of the present invention, S120 is further refined on the basis of the first embodiment, that is, S120 includes: if the maintenance request is a health state maintenance request, taking a bin position provided with a bidirectional charger in the battery replacement station as a target maintenance bin position; and controlling the battery pack to be conveyed to the target maintenance bin, and recalibrating the battery pack through the bidirectional motor. Referring to fig. 3, the method specifically includes:
s210, a maintenance request of a battery pack is obtained, wherein the battery pack comprises a battery pack on a vehicle in communication connection with a power exchanging station and a battery pack arranged in the power exchanging station.
And S220, if the maintenance request is a health state maintenance request, taking the bin position provided with the bidirectional charger in the battery changing station as a target maintenance bin position.
In this embodiment, when the maintenance request is SOH maintenance, the battery pack needs to be transported to a designated maintenance bay in the battery swapping station, specifically, when it is detected that the maintenance request of the battery pack is an SOH maintenance request, the battery pack management system sends an SOH maintenance request instruction to a station control host in a station level monitoring system, the station control host further determines the number of available maintenance bays provided with a bidirectional charger in the battery swapping station and available discharge loads, and determines whether to perform the battery pack maintenance operation according to comparison between the number of target maintenance bays required by the maintenance request and the required discharge loads and the number of available maintenance bays provided with the bidirectional charger in the battery swapping station and the available discharge loads.

The battery pack management system starts a charging process after receiving a station control SOH maintenance charging instruction, enters a charging state, and sends a maintenance charging state instruction to the station control host: BMSH _ BatMaintain _ State is 0x3, Maintenance Charging, and then sends a Charging instruction to a Charging motor in the station; the in-station charging motor receives a station control SOH maintenance charging instruction: after the GSCADA _ BMSH _ CHG _ Ctrl is 0x3, starting a charging process after the SOH Maintain Charge, requesting to Charge a battery pack by a battery pack management system according to a set charging rate, then starting charging by a charging motor in the station, monitoring the charging process by the battery pack management system, sending a charging stop/standby instruction to the charging motor in the station by the battery pack management system when the highest single voltage is more than or equal to a charging voltage threshold value, and updating an SOH maintenance result according to the actual charging capacity.
Further, the battery pack management system sends a maintenance charging completion instruction to the station control host: setting BMSH _ BatMaintain _ State to 0x4, and setting the SOH Maintenance requirement as no requirement, and clearing the starting mileage and the starting times of the SOH Maintenance. And after receiving the state of charging completion maintained by the battery pack management system, the station control host marks that the battery is fully charged and is in an available state.
