Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing battery management systems face complexity and inefficiency in retaining decommissioning information for battery components, leading to time-consuming and costly procedures when replacing the BMS, which can result in loss of critical safety information.

Innovation Solution

A system with a marking element integrated into the battery component that can be permanently changed by a marking device, allowing the battery component's state to be irreversibly marked, ensuring the information is stored outside the BMS and retained even after system changes, enabling reliable and simple adaptation of the battery's operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If decommissioning information is stored in the battery management system (BMS), then the information can be accessed and processed by the BMS, but the information is lost when the BMS is changed or replaced

Engineering Contradiction:

Improveretention of decommissioning informationVSAvoidcomplexity of information transfer procedure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the decommissioning information storage function from the BMS and relocates it to a marking element that is permanently associated with the battery component. This marking element contains a marking device that can permanently mark the battery component when decommissioning conditions are met, ensuring information persistence independent of BMS changes.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a marking element as an intermediary between the BMS and the battery component. The marking element includes a marking device that physically marks the battery component, serving as a permanent record that bridges the gap between temporary BMS storage and permanent information retention, eliminating the need for complex information transfer procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If decommissioning information is stored in the BMS, then it can be managed centrally, but extensive and error-prone transfer procedures are required when changing the BMS

Engineering Contradiction:

Improvesimplicity of BMS replacement procedureVSAvoidloss of decommissioning information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent implements preliminary action by having the marking device permanently mark the battery component during normal operation before BMS replacement is needed. This advance marking ensures that decommissioning information is already recorded on the battery component itself, eliminating the need for rushed or complex information transfer procedures during BMS replacement.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent treats the BMS as a temporary, replaceable component while the marking element serves as a permanent record. The marking element's permanent marking capability acts as a low-cost, simple solution that prevents information loss during BMS replacement, making the replacement process as simple as swapping the BMS without additional information transfer steps.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Productivity

If the BMS is changed to update or maintain the system, then system maintenance can be performed, but time-consuming and costly procedures are required to transfer decommissioning information

Engineering Contradiction:

Improvespeed of BMS replacementVSAvoidtime for information transfer

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent extracts the decommissioning information from the BMS memory and stores it permanently in the marking element associated with the battery component. This separation allows BMS replacement to be performed quickly without any information transfer procedures, as the marking element retains all necessary decommissioning information independently of the BMS.

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If decommissioning information is retained in the BMS, then it can be processed by the system, but complex and expensive procedures are required to ensure information transfer

Engineering Contradiction:

Improveaccuracy of decommissioning informationVSAvoidcost and complexity of information transfer system

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements self-service by enabling the marking device within the marking element to autonomously mark the battery component when decommissioning conditions are detected. This self-marking capability eliminates the need for complex external information transfer systems or procedures, reducing both cost and complexity while maintaining high reliability of decommissioning information.

Inventive Principle:

Principle #25Self-service
