Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling battery charging and discharging in vehicles are inefficient due to variability in driving conditions, making it difficult to reliably manage battery ranges based on factors like driver behavior and road conditions.
Innovation Solution
An apparatus and method that includes an inputter to detect specific driving events, a battery manager to set appropriate charge and discharge ranges, and a controller to manage battery operations within these ranges, using sensors and memory to update and store optimal battery ranges for various conditions such as steering angles, uphill/downhill driving, and stealth driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If battery charge/discharge range is fixed based on general driving conditions, then battery management is simple, but energy efficiency deteriorates due to variability in actual driving conditions
Solution Approach 1:
The battery charge/discharge range is made dynamic rather than fixed. The battery manager continuously adjusts the charge/discharge range based on real-time detection of driving events (steering angle, uphill/downhill driving, stealth driving conditions) to optimize energy efficiency for each specific driving condition.
Solution Approach 2:
The system implements feedback control by detecting actual driving conditions through sensors and using this information to adjust the battery charge/discharge range. The battery manager receives feedback about steering angle, vehicle position, and driving mode to dynamically optimize battery management parameters.
2Reliability
If battery charge/discharge range is adjusted for each specific driving condition, then energy efficiency improves, but system complexity increases
Solution Approach 1:
The driving conditions are segmented into distinct event types (steering angle events, uphill driving events, downhill driving events, stealth driving events). Each event type has its own predetermined charge/discharge range stored in memory, allowing the system to handle complexity through organized categorization rather than monolithic control logic.
Solution Approach 2:
Predetermined charge/discharge ranges for various driving conditions are pre-stored in the memory unit before actual driving occurs. When a driving condition is detected, the system quickly retrieves the appropriate pre-calculated range, avoiding the need for complex real-time calculations and reducing system complexity.
3Duration of action of stationary object
If standard battery charge/discharge range is used for all conditions, then system operation is simple, but battery lifespan deteriorates due to suboptimal charging in specific conditions
Solution Approach 1:
The battery charge/discharge range parameters are changed according to specific driving conditions. Different charge/discharge ranges are applied for different events (e.g., wider range for downhill driving with regenerative braking, restricted range for stealth driving), optimizing battery lifespan for each condition while maintaining operational simplicity through automated selection.
