EV Charging Communication via Intermediary for Remote Mobility Needs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle users face challenges in changing mobility needs information or charging status information during a charging session, especially when out of proximity to the vehicle, due to safety regulations and complex access procedures through OEM servers, which complicates billing and payment processes.
Innovation Solution
A method and apparatus enabling users to access and change mobility needs information via a secondary actor involved in power transfer, with mutual authentication between the OEM server, power transfer apparatus, and secondary actor, ensuring information authenticity through message exchange and data formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users access the EV through OEM server for remote configuration, then mobility needs information can be changed remotely, but the access procedure becomes complicated and billing difficulty increases
Solution Approach 1:
The patent introduces a secondary actor (charging station operator or power transfer apparatus) as an intermediary between the user and the EV. This intermediary receives configuration requests from the user and forwards them to the EV, eliminating the need for direct user access through the complex OEM server authentication process. The secondary actor already has established communication channels with the EV, making the configuration process simpler for users.
2Ease of operation
If users access the EV through OEM server for remote configuration, then mobility needs information can be changed remotely, but payment and billing processes become difficult
Solution Approach 1:
The secondary actor serves as a payment intermediary, handling billing and payment processes between the user and the power transfer service. Since the secondary actor is already involved in the charging transaction, they can manage payment authentication and billing records more efficiently than a separate OEM server system, simplifying the overall payment process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to remotely acquire and modify mobility needs information or charging status from outside the vehicle, ensuring secure and authentic information exchange during charging sessions.
Implementation Method 1
a reception pad of a vehicle assembly (VA) mounted in the electric vehicle may form an inductive resonance coupling with a transmission pad of a ground assembly (GA) installed at a charging station or a charging spot and may charge the battery of the EV using electric power transferred from the ground assembly through the inductive resonance coupling

AI summary
A power transmission method according to the present disclosure comprises the steps of: receiving, from a user of mobility, a current mobility needs request related to charging of the mobility; transmitting current mobility needs information to the user; receiving, from the user, a new mobility needs configuration request related to the charging of the mobility; and transmitting, to the user, a result message notifying whether or not new mobility needs have been applied to the mobility.
