Multi-Standard EV Charging Terminal With Selective Socket Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric vehicle charging infrastructure faces challenges due to the variety of charging standards, leading to the need for cumbersome and potentially unsafe adapter solutions, which can cause discomfort and safety risks when used with different charger standards.
Innovation Solution
An electric vehicle charging terminal with multiple sockets of different standards, featuring a sliding door mechanism that exposes only the appropriate socket for charging, controlled by a user or automated system, while blocking other sockets for safety and convenience, and sets a maximum charging voltage based on the exposed socket type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple charging sockets of different standards are exposed simultaneously, then compatibility with various charger standards is improved, but safety risks and operational confusion increase
Solution Approach 1:
The patent implements a sliding door mechanism that dynamically changes the state of charging sockets from all exposed to selectively exposed based on operational needs. The sliding door can move between positions to reveal only the required socket type (AC, DC, or both), transforming the static configuration into a dynamic one that adapts to different charging scenarios while maintaining safety by concealing unused sockets.
2Adaptability or versatility
If charger adapters are used to connect different standards, then compatibility is improved, but device complexity and safety risks increase
Solution Approach 1:
The charging terminal is designed with multiple charging sockets (AC and DC) integrated into a single device, eliminating the need for separate adapters. The sliding door mechanism provides universal access to different socket types, allowing the terminal to function with various charger standards directly without requiring additional intermediary devices.
3Adaptability or versatility
If charger adapters are used beyond allowable voltage and output, then compatibility is maintained, but harmful effects such as fire or explosion increase
Solution Approach 1:
The sliding door mechanism extracts or isolates the unused charging sockets from accessibility, removing the potential source of harmful effects. By concealing sockets that are not currently needed, the system prevents improper connections and voltage mismatches that could lead to fire or explosion risks.
4Ease of operation
If all charging sockets are always accessible, then ease of operation is improved, but safety control is worsened
Solution Approach 1:
The sliding door provides dynamic control over socket accessibility, allowing the system to switch between states of full accessibility and selective concealment. This dynamic mechanism maintains ease of operation when needed while enabling safety control by limiting access to only the required socket type during charging operations.

AI summary
An electric vehicle charging terminal includes: a first socket; a second socket disposed at upper and lower or left and right of the first socket, and having a different standard from the first socket; an outer cover blocking the first socket and the second socket from the outside and opened and closed; and a sliding door disposed between the outer cover and the first socket or the second socket, and configured to move up and down or left and right to expose only one of the first socket or the second socket and block the other socket, in which the sliding door is configured to select a socket to be exposed among the first socket or the second socket by up and down or left and right movement. As a result, the electric vehicle charging terminal May use the chargers of different standards to block unused sockets during charging to improve the safety.
