Wireless Battery Data Collection System for Vehicle Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data collection methods for vehicles, particularly electric and hybrid vehicles, do not effectively manage and collect battery information after shipment from the factory, requiring physical connection or unit retrieval for data acquisition.
Innovation Solution
A data collection method and system that wirelessly acquires and transmits battery information from vehicles to a dedicated server, using a battery monitoring unit and a power management ECU to periodically send data, allowing for identification and analysis of battery status and deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical connection or unit retrieval is used to collect battery information, then data acquisition is possible, but operation complexity and time consumption increase
Solution Approach 1:
The patent replaces the mechanical physical connection method with wireless communication technology. The battery information collection device establishes wireless communication with the vehicle's battery management system to transmit and collect battery data without physical contact, thereby eliminating the need for manual connection operations while maintaining data acquisition accuracy.
Solution Approach 2:
The patent introduces a battery information collection device as an intermediary component that mediates between the vehicle's battery management system and the external analysis system. This intermediary device handles the communication and data transmission processes, allowing remote data collection without requiring direct physical access to the battery units.
2Measurement precision
If physical connection or unit retrieval is used to collect battery information, then data acquisition is possible, but time consumption increases
Solution Approach 1:
The patent replaces the mechanical physical connection method with wireless communication technology. The battery information collection device establishes wireless communication with the vehicle's battery management system to transmit and collect battery data without physical contact, thereby eliminating the need for manual connection operations while maintaining data acquisition accuracy.
Solution Approach 2:
The patent enables the battery information collection device to autonomously connect and collect data through wireless communication without requiring manual intervention. The system automatically establishes communication with the vehicle's battery management system, retrieves the necessary information, and transfers it for analysis, significantly reducing the time required for data collection.
3Ease of operation
If battery information is not collected systematically, then vehicle operation is simple, but battery deterioration management becomes difficult
Solution Approach 1:
The patent implements a feedback mechanism where battery information is continuously collected, transmitted, and analyzed. The system processes the collected data to assess battery status and deterioration trends, then provides feedback for predictive maintenance decisions. This enables proactive battery management while maintaining simple vehicle operation through automated monitoring.
Solution Approach 2:
The patent enables preliminary analysis of battery information before actual deterioration occurs. By continuously collecting and analyzing battery data, the system can predict potential issues and schedule maintenance in advance, preventing failures before they impact vehicle operation or reliability.
Data Source
AI summary
A data collection system that collects information indicating a status of a battery mounted on a vehicle from the vehicle after shipment from a factory, includes a battery information collection server that is configured to periodically receive information of the battery and identification information, with which it is possible to identify the vehicle, that are transmitted wirelessly from a computer that is mounted on the vehicle and is configured to acquire and store the information of the battery mounted on the vehicle. The data collection system may further include a battery information analysis section that is configured to display a result of associating the information of the battery received by the battery information collection server with each vehicle using the identification information.
