Solution Overview

Problem

Charging abnormalities in vehicle charging stations are not adequately addressed, leading to instances where batteries cannot be properly charged.

Innovation Solution

A processing apparatus and control device that acquire and associate abnormality information from charging stations with vehicle information, allowing for the sequential accumulation and search for charging stations based on this data to prevent charging abnormalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If charging is performed using a charger at a charging station, then the battery can be charged with electric power, but charging abnormalities may occur that prevent proper charging

Engineering Contradiction:
Improvecharging reliabilityVSAvoidcharging abnormality
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by accumulating abnormality information and vehicle information in advance before charging occurs. The server stores historical data about charging abnormalities and vehicle characteristics, then uses this pre-acquired information to search for and recommend suitable charging stations before the actual charging takes place, preventing charging abnormalities proactively

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback mechanism where abnormality information from charging stations and vehicle information are continuously acquired, accumulated, and stored. This feedback loop allows the server to learn from past charging experiences and use the accumulated data to make informed recommendations, improving charging reliability through iterative learning

Inventive Principle:
Principle #23Feedback

2Reliability

If abnormality information and vehicle information are accumulated for searching charging stations, then charging abnormalities can be suppressed, but information processing complexity increases

Engineering Contradiction:
Improvecharging reliabilityVSAvoidinformation processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The server acts as an intermediary that handles the complex information processing tasks. Instead of requiring the charging station or vehicle to directly process and match large amounts of abnormality and vehicle information, the server mediates by accumulating this information centrally and performing the search and recommendation functions, simplifying the overall system architecture

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates information copies by accumulating abnormality information and vehicle information in the server's memory. These copied and stored information sets can be efficiently searched and compared without requiring direct access to the original data sources, reducing processing complexity during charging station selection

Inventive Principle:
Principle #26Copying

AI summary

A processing apparatus includes one or more processors and one or more memories. The one or more memories are coupled to the one or more processors. The one or more processors are configured to execute a process including acquiring abnormality information that is information relating to a charging abnormality in a charging station where charging of a battery of a vehicle is performed and vehicle information that is information relating to the vehicle in such a manner that the abnormality information and the vehicle information are associated with each other, sequentially accumulating the abnormality information and the vehicle information, which are acquired, in the one or more memories in such a manner that the abnormality information and the vehicle information are associated with each other, and searching for the charging station based on the abnormality information and the vehicle information that have been previously acquired and accumulated.
