Vehicle Battery Lease Control Through Discharge Power Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to ensure effective utilization of power storage devices installed in vehicles through lease contracts, as unauthorized vehicle transfers can lead to the owner of the power storage device being unable to manage or collect the device, resulting in inefficient use and potential misuse.
Innovation Solution
A server system that communicates with vehicles equipped with power storage devices, generates restriction commands to limit discharge power if a new owner has not entered into a lease contract, and periodically checks owner information to determine changes in ownership, prompting the new owner to enter into a lease or insurance contract to avoid inconvenience and ensure proper management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle is transferred without permission of the power storage device owner, then the vehicle can be transferred to a new owner, but the power storage device owner cannot identify the transferee and cannot manage the device based on a lease contract
Solution Approach 1:
The server periodically checks owner information from a management server to detect vehicle transfers. When a transfer is detected, the system provides feedback by notifying the transferee to enter into a lease contract, thereby restoring management capability over the power storage device.
Solution Approach 2:
The server acts as an intermediary between the power storage device owner and the vehicle management system. By accessing owner information through the management server and mediating the lease contract process, the server enables indirect identification and management of transferees even when direct communication is unavailable.
2Productivity
If discharge power is restricted when the new owner has not entered into a lease contract, then the new owner can be motivated to enter into a lease contract, but the new owner experiences inconvenience due to the restriction of discharge power
Solution Approach 1:
The system applies preliminary anti-action by restricting discharge power before the transferee enters into a lease contract. This preemptive measure creates inconvenience that motivates the transferee to comply with the lease contract requirements, thereby preventing future management issues.
Solution Approach 2:
The discharge power restriction, initially a harmful inconvenience to the transferee, is converted into a beneficial motivational tool. The inconvenience serves as an incentive for the transferee to enter into the lease contract, ultimately benefiting both the owner (through proper device management) and the transferee (through restored full functionality).

AI summary
A server communicates with a vehicle that includes a battery. The server includes a communication device and a processing device. The communication device is configured to communicate with the vehicle. The processing device is configured to generate a restriction command for restricting discharge power of the battery. A first owner (user) as an owner of the vehicle has entered into a first lease contract for leasing the battery. When the owner has been changed from the first owner to a second owner and the second owner does not enter into a second lease contract for leasing the battery, the processing device transmits a restriction command to the vehicle through the communication device.
