Vehicle Battery Plug Light Control for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with battery-powered systems, the existing lighting solutions for plug receiving portions consume excessive battery power when the vehicle is in motion, as the light remains on even when there is a low likelihood of plug insertion, which is inefficient.
Innovation Solution
Implementing an electronic switch that turns off the light when the vehicle enters a running mode, and using a series connection of a lid switch and transistor switch to control the light's on/off state, ensuring the light is only on when necessary, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light is kept on when the lid is opened during vehicle running, then the plug receiving portion is illuminated for visibility, but the battery power consumption increases unnecessarily
Solution Approach 1:
The lighting system dynamically adjusts its operation based on vehicle running state. When the vehicle is in running mode, the light is automatically turned off even if the lid is open, as indicated by the fifth aspect of the invention. This dynamic control prevents unnecessary power consumption during vehicle operation while maintaining illumination when the vehicle is stationary and plug insertion is needed.
Solution Approach 2:
The system changes the operational parameter of the light (on/off state) based on the vehicle's running state parameter. The control unit monitors whether the vehicle is in running mode and accordingly adjusts the light's illumination state, transitioning from a static lighting control approach to a parameter-based dynamic control approach that optimizes power consumption.
2Ease of operation
If the light is turned on when the lid is opened, then the plug receiving portion becomes visible, but the power consumption cannot be minimized when running mode is active
Solution Approach 1:
The lighting system implements dynamic control by integrating vehicle running state detection. The control unit receives signals about the vehicle's running mode and automatically adjusts the light's operation accordingly. This creates a adaptive lighting system that balances visibility needs with energy conservation based on real-time vehicle operational conditions.
Solution Approach 2:
The system incorporates feedback from the vehicle's running state detection to control the lighting. The control unit continuously monitors whether the vehicle is in running mode and uses this feedback information to determine whether to activate the light, creating a closed-loop control system that optimizes power usage based on actual operational requirements.
