Charging Station Display State Switching for Heat and Power Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging station display devices face damage from extreme temperatures and generate waste heat, which can negatively affect power supply and battery storage, especially in fast charging stations for electric vehicles.
Innovation Solution
A method to operate the display device based on temperature states of the display device and the charging station, involving switching states such as backlight on/off and device on/off to manage waste heat and protect the display from damage, using sensors and a control unit to determine optimal operating states and adjust climate conditioning load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display device is operated continuously to display information and advertisements, then the display device can fulfill its information display function, but the display device generates waste heat that negatively affects power supply and battery storage capacity
Solution Approach 1:
The display device operates in dynamic modes (full operation, reduced operation, shutdown) based on real-time temperature conditions of the charging station, allowing the system to adapt between information display needs and waste heat reduction
Solution Approach 2:
The operating parameters of the display device (power consumption, brightness, operation duration) are changed based on temperature parameters of the charging station, transitioning between different operational states to optimize the balance between display functionality and heat generation
2Use of energy by moving object
If the display device operates at high power to display advertisements, then the display device can effectively communicate information, but the display device temperature increases and may cause permanent damage to the display
Solution Approach 1:
The control unit continuously monitors the temperature of the display device and charging station, using this feedback to dynamically adjust the display operating state, thereby preventing temperature-related damage while maintaining display functionality when conditions permit
Solution Approach 2:
The system proactively shuts down or reduces display operation before critical temperature thresholds are reached, preventing permanent damage to the display device by taking preventive action based on temperature monitoring
3Loss of energy
If the display device is switched off to reduce waste heat, then the waste heat generation is reduced, but the display device cannot display information and advertisements
Solution Approach 1:
The display device transitions dynamically between different operational states (full operation, reduced operation, shutdown) based on temperature conditions, ensuring information display capability is maintained when thermally permissible while reducing heat generation when temperatures are high
