Battery Information Retrieval via User Terminal Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in obtaining battery information from electric vehicles when communication devices are unavailable or non-existent, hindering processes like lease fee calculations for secondary batteries.
Innovation Solution
A server system that retrieves battery information from a user's terminal instead of the electric vehicle, using a communication unit and control unit to obtain and manage battery data, even if the electric vehicle cannot transmit it, by establishing short-range wireless communication and prompting users to provide the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server receives battery information only from the electric vehicle, then the communication system is simple, but the server cannot obtain battery information when the electric vehicle cannot communicate with the server
Solution Approach 1:
The user terminal acts as an intermediary between the electric vehicle and the server. When the electric vehicle cannot directly communicate with the server, the terminal receives battery information from the vehicle and forwards it to the server, ensuring continuous information acquisition while maintaining a relatively simple communication architecture
Solution Approach 2:
The user terminal is given multiple functions: it serves as both a user interface device and a communication relay. The terminal can directly communicate with the server when the vehicle cannot, or forward information from the vehicle to the server, making the system adaptable to different communication scenarios without requiring separate dedicated devices
2Loss of information
If the server requests battery information frequently from the terminal, then the battery information is always up-to-date, but the communication load and energy consumption increase
Solution Approach 1:
The server requests battery information from the terminal at predetermined periodic intervals rather than continuously or on-demand. This periodic communication strategy ensures the battery information remains sufficiently up-to-date for lease fee calculations while significantly reducing the communication frequency, thereby lowering the terminal's energy consumption and communication load

AI summary
A server includes: a communication unit that communicates with a mobile terminal (terminal) of a user; and a processor (control unit) that controls the communication unit. When the communication unit has not received deterioration information (battery information) on a battery from the mobile terminal for greater than or equal to a cycle (predetermined period), the processor performs control for obtaining the deterioration information through the mobile terminal.
