Rail-Mounted EV Charger Transfer for Flexible Parking Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile electric vehicle charging systems face limitations such as restricted use due to multiple chargers competing on a single rail, increased costs due to the need for a driving unit in each charger, and inconvenience for users who must immediately remove their vehicles after charging is complete.
Innovation Solution
A rail mobile electric vehicle charging system that allows multiple chargers to move along a rail, eliminating the need for a driving unit in each charger by using a separate moving unit and enabling remote unplug of charge guns, while incorporating cameras for monitoring and thermal imaging for fire detection and response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mobile chargers are implemented to move along one guide rail, then charging flexibility is improved, but charger movement is restricted when another charger is charging
Solution Approach 1:
The system divides the charging function into two separate components: a moving unit that travels along the rail to transport chargers, and stationary chargers that remain at charge spots. This segmentation allows multiple chargers to be served by a single moving unit without interfering with each other's charging operations, resolving the contradiction between charging flexibility and movement restrictions.
2Ease of operation
If a driving unit is installed in each mobile charger, then charger mobility is achieved, but charger cost increases
Solution Approach 1:
The system merges the movement function into a separate moving unit that serves multiple chargers, rather than equipping each charger with its own driving unit. This consolidation reduces the total number of driving units needed, lowering charger costs while maintaining mobility through the shared moving unit that transports chargers along the rail.
3Reliability
If the user must unplug the charge gun, then charging completion is confirmed, but user convenience decreases
Solution Approach 1:
The system implements self-service through automatic charge gun retraction and detachment mechanisms. After charging completion is detected, the charger automatically retracts the charge cable and detaches the charge gun from the vehicle, eliminating the need for user intervention. This maintains reliable charging completion confirmation while significantly improving user convenience.

AI summary
The present disclosure relates to a rail mobile electric vehicle charging system capable of charging an electric vehicle by moving an electric vehicle charger to a certain position through a method of moving a plurality of electric vehicle chargers to a predetermined charge spot using a moving unit that moves along a rail and connecting an input port of the electric vehicle charger to a power terminal provided at the charge spot, so that there is no need to designate a dedicated parking lot for electric vehicle charging, and there are no problems with charging the electric vehicle even if electric vehicles and regular engine vehicles are parked without distinction, and there is no need to move the electric vehicle to another space even after charging is completed, thereby maximizing the convenience of charging and providing fire monitoring and fire extinguishing functions.
