Vehicle Encapsulation Monitoring for Subsystem Failure Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current encapsulation monitoring systems for battery-powered vehicles lack the ability to individually monitor each subsystem connected to the energy storage system, making it difficult to quickly identify and address failures, which can compromise safety.
Innovation Solution
An encapsulation monitoring system comprising a communication element, a malfunction monitoring element, and a control unit that allows for independent monitoring of each subsystem by assessing the availability or unavailability of the power supply, enabling quick identification and resolution of failures through binary status reports and user-friendly interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 12 V loop connected to all low voltage and high voltage connectors in series is used for monitoring, then the electrical encapsulation can be monitored, but it is difficult to identify the specific failure location in individual subsystems
Solution Approach 1:
The monitoring system is segmented into multiple independent monitoring units, each assigned to a specific subsystem. Each unit includes a malfunction monitoring element and communication element that can independently monitor its designated subsystem's power supply status, enabling precise failure location identification without requiring a complex series loop structure
2Loss of time
If individual subsystem monitoring is implemented, then failure location can be quickly identified, but the system complexity increases
Solution Approach 1:
Each subsystem is equipped with its own malfunction monitoring element that autonomously detects power supply availability and communicates status information. The system performs self-monitoring without requiring external intervention, enabling rapid failure identification while maintaining a relatively simple distributed architecture where each unit operates independently

AI summary
The present disclosure relates to an encapsulation monitoring system for a vehicle, a vehicle comprising such encapsulation monitoring system, an encapsulation monitoring method and a computer program element for such encapsulation monitoring system. The encapsulation monitoring system comprises a communication element, a malfunction monitoring element, and a control unit. The communication element and the malfunction monitoring element are arrangeable on at least one subsystem of the vehicle. The subsystem is supplied by an energy storage system. The malfunction monitoring element is configured to identify an availability of a power supply if the subsystem is connected to the energy storage system. The malfunction monitoring element is configured to identify an unavailability of the power supply if the subsystem is disconnected from the energy storage system. The control unit is configured to send a status request to the communication element. The communication element is configured to send a status report in response to the status request to the control unit. The status report contains only an availability or an unavailability of the power supply.
