Location-Based EV Power Mediation Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems require separate fixed units for charging and discharging, leading to high facility costs and inefficient power usage due to standby power consumption in user authentication components, where the person paying for standby power may not coincide with the actual user.
Innovation Solution
A location-based power mediation system that uses a module, electric vehicle, and intermediate server to charge and discharge electric vehicles without a separate fixed unit, incorporating a location and time identification unit, power measurement unit, and wireless communication to manage power transactions between power subscribers and sale companies, and a user authentication socket or connector that does not consume standby power while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate fixed charging units are installed for electric vehicle charging, then charging functionality is provided, but facility costs and device complexity increase
Solution Approach 1:
The patent extracts the authentication and control functions from the fixed charging unit and relocates them to the portable connector. This allows the main charging functionality to remain distributed at existing sockets while centralizing smart control in a portable device, thereby reducing facility complexity while maintaining charging convenience
Solution Approach 2:
The portable connector acts as an intermediary between the power socket and the electric vehicle. It mediates the charging process by providing authentication, control, and monitoring functions without requiring the socket itself to be complex, thus simplifying the fixed infrastructure while enabling convenient charging
2Reliability
If user authentication components are always powered for security, then authentication reliability is improved, but standby power consumption increases
Solution Approach 1:
The authentication components in the portable connector are powered periodically or on-demand rather than continuously. The connector activates authentication functions only when needed for charging operations, thereby maintaining security reliability while dramatically reducing standby power consumption
Solution Approach 2:
The system uses the power being charged to the electric vehicle to supply the authentication components. The charged battery itself serves to power the authentication system, eliminating the need for separate standby power supply while maintaining continuous authentication capability

AI summary
The present invention relates to a location-based charging/discharging power mediation system of an electric vehicle, and more particularly to a module, an electric vehicle, and an intermediate server for location-based charging/discharging power mediation. The present invention also relates to a user authentication socket or connector used in the power mediation system. A module for location-based power mediation comprises: a location and time identification unit that identifies a location and a time of an electric vehicle from one or more of information from a global navigation satellite system, Local Positioning System (LPS) information, and earth magnetic field information; a power measurement unit that monitors input/output power to/from the electric vehicle in real time; and a wireless communication unit that transmits location and time information of the electric vehicle and information on the input/output power to the outside. An electric vehicle power mediation subscriber charges/discharges a battery of the electric vehicle through a building of a power subscriber by inserting a plug of the electric vehicle into a socket of the building of the power subscriber. A location of the building and the power subscriber are identified by transmitting the location and time information of the electric vehicle.
