Vehicle Control System Battery Temperature Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in maintaining battery temperature when the external power source is not available, leading to a decrease in remaining battery level, which can inhibit temperature regulation and result in battery deterioration.
Innovation Solution
A vehicle control system that transmits notifications to the user when predetermined conditions for activating auxiliary devices like the battery heater are met, and the external power source is unavailable, ensuring the user connects an external power source to prevent battery level depletion by regulating battery temperature using either external or internal power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If battery temperature regulation is performed using the vehicle's internal battery power, then the battery temperature can be maintained at appropriate levels, but the remaining battery level decreases
Solution Approach 1:
The notification system acts as an intermediary between the battery management system and the user. When the battery temperature regulation function is activated, the system sends a notification to the user's terminal device, prompting them to connect an external power source. This intermediary communication mechanism resolves the contradiction by informing users of the power consumption situation without directly controlling the temperature regulation process.
Solution Approach 2:
The system implements feedback by monitoring the battery temperature and remaining battery level, then communicating this status information to the user through notifications. When the temperature regulation is active and battery level is decreasing, the feedback loop triggers a notification to the user's terminal, enabling the user to take appropriate action (connecting external power) to resolve the energy consumption issue.
2Adaptability or versatility
If the vehicle is not connected to an external power source, then the vehicle maintains operational independence, but the battery temperature regulation cannot be performed when needed
Solution Approach 1:
The system performs preliminary action by proactively notifying the user before the battery temperature becomes problematic or before the battery level becomes critically low. The notification is sent in advance, giving the user time to connect an external power source before the vehicle's internal power is depleted or temperature issues arise, thus maintaining both operational independence and temperature regulation capability.
3Temperature
If battery temperature regulation is continuously performed, then the battery remains at optimal temperature, but unnecessary battery discharge occurs when external power is available
Solution Approach 1:
The system dynamically adjusts the temperature regulation strategy based on the availability of external power sources. When external power is detected, the system can maintain temperature regulation without depleting the vehicle's internal battery. When external power is unavailable, the system notifies the user and adjusts its operation to conserve battery energy, creating a dynamic response that resolves the contradiction between temperature stability and energy conservation.
