Modular EV Charging Plugs for Time-Displaced Power Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle charging infrastructure is inefficient and costly due to the need for separate charging stations for each vehicle, high installation costs, and underutilization of charging capacity, particularly in private and public environments where vehicles are often idle for extended periods.
Innovation Solution
A modular charging device that allows multiple electric vehicles to be charged sequentially using a single charging station, with an intelligent distribution unit and connection plugs compatible with various charging standards, ensuring only one vehicle is charged at a time to prevent overload and optimize charging capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate charging station is installed for each electric vehicle, then each vehicle can be charged independently and reliably, but the installation costs increase significantly and the infrastructure becomes complex
Solution Approach 1:
The patent combines multiple charging points into a single charging station that can serve multiple electric vehicles simultaneously. The charging station includes a power supply unit connected to multiple connection plugs, allowing several vehicles to share one infrastructure unit, thereby reducing overall system complexity and installation costs while maintaining reliable charging capability for each vehicle
Solution Approach 2:
The charging station is designed with universal functionality to serve multiple purposes and multiple vehicles through a single unit. The power supply unit can distribute charging current to multiple connection plugs, making the infrastructure adaptable to different vehicle needs and reducing the number of separate stations required
2Productivity
If multiple electric vehicles are charged simultaneously at the same charging station, then charging capacity is maximized and waiting time is reduced, but the available power must be divided and each vehicle receives less charging power
Solution Approach 1:
The charging station employs dynamic load management that automatically adjusts the charging current distribution based on real-time conditions. The control unit monitors the state of charge, battery capacity, and charging progress of each connected vehicle, dynamically allocating power to optimize overall charging throughput while ensuring each vehicle receives appropriate charging power based on its specific needs
3Loss of energy
If the charging station provides maximum charging current to multiple vehicles simultaneously, then total energy output is maximized, but the risk of overload and safety issues increases
Solution Approach 1:
The charging station incorporates a control unit that continuously monitors the charging current, voltage, and power consumption of each connected vehicle. This feedback mechanism allows the system to detect potential overload conditions and automatically adjust the current distribution to prevent exceeding safety limits, thereby maintaining high energy delivery efficiency while eliminating overload risks
Solution Approach 2:
The system implements preventive safety measures by establishing maximum current limits and monitoring thresholds before overload conditions can develop. The control unit is pre-configured with safety parameters that cushion against potential harmful effects by preventing the system from entering dangerous operating states in the first place
