Apartment EV Charging Layout With Shared Station and Satellite Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-port vehicle charging stations are limited by the number of parking spots they can serve due to the need for dedicated electrical circuits, and they require manual transactional payment each time, lacking predictive scheduling and efficient load management for high-density deployments.
Innovation Solution
A facility-wide charging system with a shared charging station connected to multiple satellite ports, using load management and proximity-based authentication to optimize charging based on user and vehicle behavior, enabling automatic payment and efficient load distribution across multiple vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single charging station integrates multiple ports (2-4 ports), then the number of vehicles that can charge simultaneously increases, but the deployment cost and electrical circuit requirements increase proportionally
Solution Approach 1:
The system divides the charging infrastructure into a central charging station and multiple satellite ports distributed across parking spaces. Each satellite port is a separate, simpler unit that connects to the central station, allowing the system to serve multiple vehicles without requiring each vehicle to connect to a complex multi-port station. This segmentation reduces the complexity at each individual charging point while maintaining high overall capacity.
2Reliability
If manual transactional payment is required each time, then revenue collection is ensured, but user convenience and charging speed decrease
Solution Approach 1:
The system performs preliminary actions by requiring user registration and vehicle identification before charging begins. Once registered, the payment transaction is pre-arranged and automatically executed, eliminating the need for manual payment at the charging moment. This preliminary setup enables both reliable revenue collection and convenient, fast charging for returning users.
Solution Approach 2:
The system implements self-service through automatic payment processing that occurs without direct user intervention at the charging station. The registered user's vehicle is automatically identified, authenticated, and billed through the system, freeing users from manual transaction steps while ensuring reliable payment collection.
3Ease of operation
If charging stations are positioned for adjacent parking spaces, then vehicle access is simplified, but the number of serviceable parking spots is limited
Solution Approach 1:
The system transitions from a horizontal arrangement where multiple ports are clustered in one location to a distributed spatial arrangement where satellite ports are spread across multiple parking spaces. This dimensional redistribution allows the charging infrastructure to serve a larger area and more parking spots while maintaining easy vehicle access at each individual port location.

AI summary
Devices, methods, and systems for EV charging. Some implementations provide an EV charging subscription service to apartment residents. Infrastructure is installed in a parking facility. When residents subscribe, they are assigned a parking spot with a charging port that matches their vehicle. In some implementations, hardware and software assume that many vehicles are charged, that parking spots are assigned to a specific car, and that driving behavior averages out over many vehicles.
