High-Voltage Battery Warning System for Emergency Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency responders face challenges in assessing the state of a high-voltage battery in a motor vehicle after an accident, as existing systems require special hardware and software, and there is a need for a method to provide detailed information about the battery's safety status with minimal effort.
Innovation Solution
A warning method that involves creating individual and total state diagnoses of the high-voltage battery components using sensor data, transmitting these diagnoses to external monitoring units, and alerting emergency responders through a communication system, including an eCall connection, to differentiate between safe and dangerous states, and providing visual or acoustic warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing warning devices are used to provide information about the high-voltage battery state, then emergency responders can assess potential danger, but special hardware and software (smartphone or tablet PC) are required which emergency responders must carry to the accident site
Solution Approach 1:
The patent extracts the essential diagnostic information from the complex evaluation system and transmits only the critical state diagnosis (dangerous/not dangerous) and individual component diagnoses to external units. This extraction principle eliminates the need for emergency responders to carry special hardware, as the information is transmitted via standard communication interfaces to readily available devices.
Solution Approach 2:
The patent introduces a communications unit as an intermediary that bridges the vehicle's diagnostic system and external monitoring units or emergency call dispatchers. This intermediary handles the complex data transmission and interpretation, allowing emergency responders to receive processed information through standard interfaces without needing specialized equipment.
2Loss of information
If detailed state diagnoses of individual high-voltage battery components are provided, then comprehensive safety information is available, but the system complexity and data transmission requirements increase
Solution Approach 1:
The patent segments the diagnostic information into two distinct levels: individual component state diagnoses for specific high-voltage battery components, and an overall total state diagnosis for the entire battery system. This segmentation allows detailed information to be provided when needed while maintaining system manageability, as each segment can be evaluated and transmitted independently through standard communication interfaces.
Solution Approach 2:
The patent applies local quality by providing different levels of diagnostic detail to different recipients based on their needs. The total state diagnosis is transmitted to emergency call dispatchers for immediate emergency response, while individual component state diagnoses are made available to vehicle-external monitoring units for detailed analysis. This localized information quality optimization reduces unnecessary data transmission complexity while maintaining comprehensive information availability where required.

AI summary
A warning method for a high-voltage battery of a motor vehicle, with which, in the case of an accident of the motor vehicle, emergency responders can be provided details on the state of the high-voltage battery of the motor vehicle after the accident. This warning method includes at least one state diagnosis relating to at least one component of the high-voltage battery is created on the basis of supplied sensor data by means of an analysis unit, as soon as the accident of the motor vehicle has been detected. In addition, a total state diagnosis of the high-voltage battery based on this at least one state diagnosis is created. The at least one state diagnosis is transmitted via a corresponding communications unit to a vehicle-external monitoring unit, and the total state diagnosis of the high-voltage battery is transmitted via this communications unit to an emergency call dispatcher.
