EV Charging Positioning Visualization for Cable Reach and Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning a motor vehicle at a charging station is difficult due to varying charging cable lengths, which can result in the cable not reaching the vehicle's charging connection if parked too far away or risking collision if parked too close.
Innovation Solution
A positioning support system using vehicle-side sensors and a data memory to determine surroundings information, visualize the charging cable range, and display it on the vehicle's display, considering vehicle and charging station properties, to facilitate accurate parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle is parked farther away from the charging column, then the risk of collision is reduced, but the charging cable may not reach the vehicle's charging connection
Solution Approach 1:
The patent introduces an intermediary system consisting of a data memory storing charging cable length information and a display unit showing the cable's reach range. This intermediary provides the driver with visual feedback about the cable's maximum reach, enabling informed positioning decisions that balance connection reliability and collision avoidance without requiring direct trial-and-error positioning.
Solution Approach 2:
The system performs preliminary action by providing the driver with charging cable length information before the actual charging connection is made. The display unit shows the reach range in advance, allowing the driver to position the vehicle appropriately before attempting connection, thereby preventing both failed connections and collisions.
2Ease of operation
If the vehicle is parked closer to the charging column, then the charging cable can reach the vehicle's charging connection, but the risk of collision increases
Solution Approach 1:
The display unit acts as an intermediary that translates the abstract charging cable length into a visual reach range indicator. This allows the driver to easily determine the appropriate parking distance without guessing, making the charging connection process simple while simultaneously indicating the safe positioning zone that avoids collisions.
Solution Approach 2:
The system provides visual feedback through the display unit that shows the charging cable's reach range relative to the charging column. This feedback loop enables the driver to adjust vehicle positioning based on real-time information, achieving easy connection while avoiding collision risks through informed decision-making.
3Adaptability or versatility
If the charging cable length varies across different charging stations, then the system must adapt to different cable lengths, but this increases the complexity of determining the correct parking position
Solution Approach 1:
The data memory stores charging cable length information in advance for different charging stations. When the driver approaches a charging station, the system retrieves the pre-stored cable length information and displays the reach range, eliminating the need for complex real-time calculations or manual adjustments when adapting to different charging stations.
Solution Approach 2:
The system performs self-service by automatically retrieving and displaying the appropriate charging cable length information based on the charging station's location. The driver simply needs to input or select the charging station, and the system autonomously provides the correct reach range information, reducing positioning determination complexity while maintaining adaptability across different stations.
