Server-Based Battery Binding Management for EV Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric vehicle batteries are limited to being bound to only one vehicle, restricting their usage and preventing sharing or lending between vehicles.
Innovation Solution
A server-based method and system that manages power supply devices with unique battery identifiers, allowing communication between user and service electronic devices to alter and confirm associations between batteries and carrier devices, enabling multiple vehicles to use the same battery by updating data stored on the power supply devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each battery is bound to only one vehicle, then the battery management system is simple and reliable, but the usage flexibility and sharing capability of batteries are limited
Solution Approach 1:
A server is introduced as an intermediary between batteries and vehicles. The server stores binding relationships between battery identifiers and carrier identifiers, and manages the binding/unbinding operations. This mediator handles the complexity of multi-vehicle battery sharing, allowing individual batteries to serve multiple vehicles without increasing complexity at the battery or vehicle level.
Solution Approach 2:
The binding relationship is moved from a direct one-to-one connection between battery and vehicle to a many-to-many relationship managed through a centralized server. This dimensional change allows a single battery to be bound to multiple carriers simultaneously, enabling flexible sharing while maintaining simple local device architecture.
2Productivity
If a battery can be used by multiple vehicles, then battery usage efficiency improves, but the risk of unauthorized use and security issues increases
Solution Approach 1:
The system implements feedback mechanisms where the server continuously monitors and manages binding relationships. When a battery is used by a vehicle, the server verifies the binding status and updates the relationship accordingly. This feedback loop ensures that only authorized vehicles can use specific batteries, maintaining security while enabling multi-vehicle usage.
Solution Approach 2:
The server acts as a security intermediary that verifies and manages all binding operations. It stores the authoritative binding relationships and controls which vehicles can access which batteries, preventing unauthorized use while enabling legitimate sharing across multiple carriers.
3Speed
If battery binding information is stored locally in each device, then access speed is fast, but data consistency across multiple vehicles cannot be maintained
Solution Approach 1:
The system merges the binding information storage into a centralized server rather than distributing it across multiple devices. The server maintains a single source of truth for all binding relationships, ensuring data consistency across all vehicles. Local devices perform fast access operations by communicating with the server, which quickly returns the necessary binding information.
Solution Approach 2:
The server stores the master copy of binding relationships and provides copies to vehicles as needed. When a vehicle needs to access battery information, the server retrieves or generates the appropriate binding data and transmits it to the vehicle. This copying mechanism maintains data consistency at the source while enabling fast local access at each vehicle.
Data Source
AI summary
A system for managing power supply devices includes a server including a database and a server end processing module. The server end processing module is configured to receive an alteration request from a user end electronic device and an alteration-confirmation signal from a service end electronic device, and send a confirmation response to the service end electronic device based on the received alteration request and alteration-confirmation signal in order for the service end electronic device to enable a target power supply device to update data stored therein.
