Dynamic On-Board Generator Inverter Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of balancing on-board and off-board power requirements in vehicles increases with the ability to provide higher levels of power to external devices, as existing power systems struggle to dynamically adjust power allocation based on load conditions and historical consumption data.
Innovation Solution
A vehicle power system with a controller that adjusts the maximum power limit of electrical systems based on detected loads, using historical power consumption data to estimate future power needs and incorporate a power provision efficiency factor, which varies with temperature and current, to optimize power distribution between on-board and off-board systems.

Engineering Contradiction Analysis
1Power
If the vehicle provides higher levels of power to external devices, then the power capability of power outlets is improved, but the complexity of balancing on-board and off-board power requirements increases
Solution Approach 1:
The system dynamically adjusts the maximum power limit of electrical systems based on real-time load detection at power outlets. The controller continuously monitors outlet load conditions and modifies the power allocation between on-board electrical systems and off-board devices, transforming a static power distribution system into a dynamic one that adapts to changing conditions.
Solution Approach 2:
The system implements feedback control by detecting the load status at power outlets and using this information to adjust the maximum power limit of electrical systems. The controller receives feedback about outlet usage and historical power consumption data, then modifies power allocation accordingly, creating a closed-loop control system that balances power requirements.
2Measurement precision
If the system uses historical power consumption data to estimate future power needs, then the power allocation accuracy is improved, but the processing complexity increases
Solution Approach 1:
The system performs preliminary analysis of historical power consumption data to estimate future power needs at power outlets. By processing past consumption patterns in advance, the controller can predict upcoming power requirements and proactively adjust the maximum power limit of electrical systems, improving power allocation accuracy without reacting to delays.
