Innovation Solution
A system where vehicle batteries are removable for quick replacement and data transfer, utilizing a data device that connects to the battery for both charging and data exchange, ensuring secure encryption and decryption of data, and allowing data transfer via a network to a remote device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transferred over wireless internet connection, then data transfer can occur without physical connection, but data security and transfer speed are limited
Solution Approach 1:
The patent introduces a dual-interface data transfer mechanism where a data interface (separate from power interface) acts as an intermediary for secure data exchange. This intermediary enables direct wired communication between the vehicle battery and external devices, providing enhanced security and speed while maintaining operational convenience through multiple transfer pathways.
2Duration of action of stationary object
If battery recharging is performed, then battery can be reused, but operational downtime increases
Solution Approach 1:
The patent implements preliminary data transfer during battery charging operations. By transferring data from the vehicle battery to external storage or computing devices while the battery is recharging, the system utilizes otherwise idle time productively, reducing the impact of charging downtime on overall vehicle productivity.
Solution Approach 2:
The charging station serves multiple functions: it recharges the vehicle battery, transfers data from the battery's memory storage, and potentially performs diagnostics or software updates. This multi-functionality converts a single-purpose operation (charging) into a composite operation that simultaneously addresses energy replenishment and data management needs.
3Quantity of substance
If more data is stored in vehicle, then better accident analysis and troubleshooting, but data security risks increase
Solution Approach 1:
The patent segments data storage across multiple locations: vehicle battery memory, external charging station storage, and potentially cloud-based repositories. This segmentation distributes the security burden and enables selective data transfer, reducing the risk associated with centralized data storage while maintaining comprehensive data availability for analysis.
Solution Approach 2:
The patent introduces encrypted data interfaces and authentication protocols as intermediaries between the vehicle battery and external systems. These intermediary security layers control data access, authenticate communication partners, and encrypt sensitive information during transfer and storage, thereby protecting against unauthorized access while enabling extensive data collection.
4Reliability
If dedicated physical link is used for data transfer, then data transfer speed and security improve, but connection complexity and setup time increase
Solution Approach 1:
The patent merges the data interface and power interface into a unified charging and data transfer system. By combining these functions at the charging station, the patent eliminates the need for separate connection procedures, reducing operational complexity while maintaining the security and speed benefits of dedicated physical data links.
Data Source
AI summary
A vehicle battery includes at least one battery cell and a battery controller for charging the at least one battery cell via a power interface of the vehicle battery. The vehicle battery further includes a battery memory and a data interface to transfer data between the battery memory and a data device external to the vehicle. A data storage controller of the vehicle battery transfers, via the data interface, data between the battery memory and the data device while the vehicle battery is removed from the vehicle. In one aspect, the data device performs at least one of transferring data from a battery memory to a memory of the data device and transferring data from the memory of the data device to the battery memory while the data device is physically connected to the vehicle battery.
