Destination-Based EV Charger Search for Standard Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging device searching systems are not suitable for finding standard charging devices, as they often require users to wait for hours due to the scarcity of quick charging stations, and are not optimized for standard charging needs.
Innovation Solution
A charging device searching system, communication terminal, and server device configuration that allows users to input a destination and search for standard charging devices within a specified area, enabling booking and authentication for standard charging, facilitating charging during activities like sightseeing or shopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the existing charging device searching system is used, then users can search for charging devices, but users have to wait for hours due to the scarcity of quick charging stations
Solution Approach 1:
The system changes the search parameter from charging device type (quick charging vs standard charging) to location-based parameters (point of destination and surrounding area). This allows users to find standard charging devices near their destination, enabling them to engage in other activities while charging, thus reducing effective waiting time despite using slower charging infrastructure.
2Adaptability or versatility
If the existing charging device searching system is used, then users can search for charging devices, but the system is not optimized for standard charging needs
Solution Approach 1:
Instead of having users search for charging devices and then plan their destination, the system inverts the approach by having users input their destination first, then automatically searching for standard charging devices in the surrounding area. This inversion optimizes the system for standard charging needs while maintaining ease of operation through intuitive destination-based searching.
3Ease of operation
If users arrive at the searched charging device location on the usage time, then charging can be performed, but users must wait for hours without doing anything
Solution Approach 1:
The system performs preliminary action by identifying and reserving standard charging devices in advance near the user's destination. This allows users to plan their trip knowing that charging capacity is secured, enabling them to engage in other activities (sightseeing, shopping, etc.) during the charging process rather than waiting idle at the charging location.

AI summary
A charging device searching system for an electrically driven vehicle, includes a point of destination inputting unit to input an information indicative of a point of destination and a searching unit to set an area around the point of destination for which the information has been input by the point of destination inputting unit as a search area and to search for the standard charging device in the set search area. The searching unit is, when a point of destination for which the information has been input by the point of destination inputting unit is within a predetermined area, to set a surrounding area of a transfer point at which a mode of transportation is switched from the electrically driven vehicle to another transportation to reach the point of destination, as the search area and to search for the standard charging device in the set search area.
