Vehicle Charging Timer Cancellation via Location Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charging systems often rely on timer functions that do not adapt to non-routine charging locations, requiring manual cancellation to charge during peak hours, which can lead to inefficient charging and higher electricity costs.
Innovation Solution
A vehicle charging system with an on-board charger, memory for storing routine charging location data, and sensors to detect environmental data, controlled by an ECU that determines the charging location and time, allowing automatic adjustment of charging times based on whether it is at a routine or non-routine location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a timer function is programmed to charge during nighttime low-demand hours, then electricity cost is reduced, but the vehicle cannot charge during daytime when needed at non-routine locations
Solution Approach 1:
The charging system dynamically adjusts the timer function based on detected location. At routine locations, the timer enforces nighttime charging for cost savings. At non-routine locations, the timer is automatically canceled to allow daytime charging when needed, providing dynamic adaptability to different charging scenarios
Solution Approach 2:
The system uses sensors to detect environmental data and determine charging location, then feeds this information back to the ECU which automatically adjusts the timer function accordingly. This feedback loop enables the system to respond appropriately to different locations without manual intervention
2Loss of energy
If the timer function operates at all locations, then electricity cost is reduced at routine locations, but manual cancellation is required at non-routine locations which can be forgotten
Solution Approach 1:
The system performs automatic location-based timer cancellation without requiring driver intervention. The sensors detect the charging location, the ECU determines whether it is routine or non-routine, and automatically cancels or maintains the timer function, making the system self-serve and eliminating human error
Solution Approach 2:
The ECU acts as an intermediary between the sensor detection and the charging control. It processes the location data, compares it against stored routine locations, and automatically manages the timer function, serving as a mediator that eliminates the need for manual driver action
3Adaptability or versatility
If manual cancellation of timer function is required at non-routine locations, then charging flexibility is achieved, but device complexity and user burden increase
Solution Approach 1:
The system automatically detects the charging location using sensors and determines whether timer cancellation is needed, eliminating the need for the driver to manually cancel the timer. The system serves itself by making the operational decision based on environmental data
Solution Approach 2:
The charging system universally handles both routine and non-routine locations through a single automated process. The same sensor-ECU-controller mechanism manages timer cancellation at non-routine locations while maintaining timer functionality at routine locations, providing multi-functional capability without adding operational complexity
