Multi-Level EV Charging Layout With Between-Floor Power Converters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging and discharging facilities for multi-story parking garages are inefficient due to the need for extensive wiring and space usage when power converter devices are placed under each floor level, and charging and discharging connectors extend from the floor or ceiling for vehicles on each level.
Innovation Solution
A charging and discharging facility with a first and second level section, where power converter devices are placed between the levels and connected by a power cable, with charging and discharging connection members extending from the ceiling and floor respectively, allowing for more efficient use of space and reduced wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power converter devices are placed under each floor level with charging and discharging connectors extending from the floor, then charging and discharging can be performed for vehicles on each level, but the wiring becomes extensive and space utilization becomes inefficient
Solution Approach 1:
The patent transitions from a two-dimensional floor-based connector arrangement to a three-dimensional configuration where connectors extend from both ceiling and floor. Power converter devices are positioned in the intermediate space between floors, utilizing the vertical dimension to reduce wiring complexity while maintaining charging functionality across multiple levels.
2Productivity
If power converter devices are placed under each floor level, then each level can independently charge and discharge batteries, but the space utilization becomes inefficient
Solution Approach 1:
The patent merges the functions of multiple power converter devices by positioning them in the intermediate space between floors rather than dedicating separate devices to each floor level. This consolidation maintains the ability to charge and discharge batteries across multiple levels while improving space utilization by eliminating redundant infrastructure.

AI summary
The charging and discharging facility has a first level section where the first charging and discharging parking space is located, a second level section where the second charging and discharging parking space is located on the floor directly above the first level section, and a power converter device connected between the first level section and the second level section by an external power cable. In the first charging and discharging parking space, the first charging and discharging connection member is attached to the end of the first charging and discharging cable extending from the ceiling of the first level section, and in the second charging and discharging parking space, the second charging and discharging connection member is attached to the end of the second charging and discharging cable extending from the floor of the second level section.
