Solution Overview

Problem

Existing systems do not determine whether a battery is in compliance with local battery laws and regulations when used in a specific area, potentially allowing non-compliant batteries to be used.

Innovation Solution

A controller system that includes a communication unit, multiple processors, and a storage unit, which obtains vehicle and battery information, determines compliance with local battery laws and regulations based on pre-set information, and transmits non-compliance notifications to the vehicle or user terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If battery authenticity is verified using ID and code information, then unauthorized batteries are prevented, but compliance with local battery laws and regulations cannot be determined

Engineering Contradiction:
Improvebattery authenticity verificationVSAvoidcompliance with local regulations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The verification system is segmented into two independent modules: one for authenticity verification (ID and code information matching) and another for regulatory compliance verification (checking battery information against local laws). This allows both functions to operate independently and simultaneously without interfering with each other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The verification system is enhanced to perform multiple functions: it not only verifies battery authenticity through ID and code matching but also checks compliance with local battery laws and regulations. The system adapts to different regional requirements by storing multiple sets of regulatory information and selecting the appropriate ones based on location.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If compliance verification is performed for every position change, then regulatory compliance is ensured, but processing load increases

Engineering Contradiction:
Improveregulatory complianceVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Instead of continuously verifying compliance for every position change, the system performs verification periodically or at specific trigger events (such as when the vehicle enters a new region with different regulations or after a predetermined time interval). This reduces unnecessary processing while maintaining compliance assurance.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system stores battery information and regulatory requirements locally, enabling the controller to perform compliance verification independently without requiring continuous external communication. This self-contained approach reduces processing load and communication overhead.

Inventive Principle:
Principle #25Self-service

3Loss of information

If non-compliance information is transmitted to user terminal, then user awareness is improved, but communication load increases

Engineering Contradiction:
Improveuser awareness of non-complianceVSAvoidcommunication energy
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The system implements a feedback mechanism where compliance status information is transmitted to the user terminal when non-compliance is detected. This feedback loop keeps users informed about their battery's compliance status, enabling them to take appropriate actions such as replacing the battery or adjusting usage patterns.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Instead of continuously transmitting compliance information, the system sends notifications only when necessary (i.e., when non-compliance is detected). This partial action approach avoids unnecessary communication energy consumption while ensuring users receive critical information when needed.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A battery information server (controller) includes a processor (first processor) that obtains position information of an electrically powered vehicle (vehicle) and battery information based on a battery pack ID (information) of a battery pack (battery) mounted on the electrically powered vehicle. The battery information server includes a communication unit and a processor (third processor) that determines whether or not the battery pack is in conformity with battery laws and regulations in a country (area) corresponding to the position information, based on information on the battery laws and regulations set in advance for each country and the battery information. When the battery pack is determined as not being in conformity with the battery laws and regulations, the communication unit transmits a result of determination by the processor to the electrically powered vehicle.
