Offline Battery Swap Authentication During Network or Cloud Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery swap operations fail when a vehicle is not connected to a network or the cloud server experiences a fault, preventing normal communication and authentication necessary for battery swap procedures.
Innovation Solution
Implementing an off-line battery swap method that allows a battery charging and swap station to switch to a backup mode, enabling communication and authentication using pre-stored backup connection and authentication information, allowing battery swaps to proceed even without network connectivity or a functional cloud server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If normal battery swap process is implemented requiring cloud server communication, then authentication and control are improved, but system reliability deteriorates when network is unavailable or cloud server fails
Solution Approach 1:
The patent applies preliminary action by pre-storing backup connection information (including account information, password information, and address information) in both the vehicle terminal and the battery charging and swap station before network connectivity is lost. This allows the system to immediately switch to offline mode without requiring real-time cloud server communication, thus maintaining battery swap reliability while avoiding the complexity of continuous network dependency
Solution Approach 2:
The patent changes the operational parameters of the communication system by switching between normal mode (relying on cloud server communication) and backup mode (using pre-stored offline information). This parameter change allows the system to adapt to different network conditions, maintaining reliability by having alternative communication parameters ready when the primary communication path fails
2Productivity
If offline battery swap mode is implemented with backup information, then service continuity is improved during network outages, but system complexity increases due to dual-mode operation
Solution Approach 1:
The patent extracts the essential authentication and connection elements (account information, password information, address information) from the complex cloud server communication system and stores them locally in both the vehicle terminal and the battery charging and swap station. This extraction allows the core battery swap function to operate independently of the cloud server, maintaining productivity during network outages while simplifying the offline operation by using only the extracted essential elements
3Reliability
If backup connection information is pre-stored in vehicle, then authentication capability is improved for offline operation, but information security risk increases
Solution Approach 1:
The patent applies beforehand cushioning by implementing a conditional authentication mechanism where the pre-stored backup connection information in the vehicle terminal is only activated and used when the battery charging and swap station explicitly switches to backup mode. This cushioning protects against unauthorized use of backup information while ensuring offline authentication reliability when genuinely needed, as the station controls when the backup information becomes active

AI summary
The invention relates to the technical field of battery charging and swap, and in particular to an off-line battery swap method, a battery charging and swap station, a vehicle with a battery to be swapped, and a readable storage medium. The invention is intended to solve the problem that battery swap cannot be performed at a battery charging and swap station when a vehicle is not connected to a network or a cloud server has a fault. To this end, the off-line battery swap method of the invention includes: switching, by a battery charging and swap station, to a backup battery swap mode upon receiving a battery swap mode switching instruction; establishing, by a vehicle with a battery to be swapped, a communication connection with the battery charging and swap station by using backup connection information; authenticating, by the battery charging and swap station, the vehicle with a battery to be swapped; and performing, by the battery charging and swap station, battery swap for the vehicle with a battery to be swapped where the authentication is successful, the backup connection information being pre-stored in the vehicle with a battery to be swapped. According to the battery swap method of this application, a battery swap procedure can be completed in an off-line state, thereby effectively solving the problem that battery swap cannot be performed when a cloud server has a fault or a vehicle with a battery to be swapped is not connected to a network.
