Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for estimating battery deterioration in electric vehicles only provide state of health (SOH) information, making it difficult for users to understand how their driving habits affect battery deterioration.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only state of health (SOH) information is provided to users, then the information processing system remains simple, but users cannot understand how their driving habits affect battery deterioration
Solution Approach 1:
The patent segments the overall battery deterioration information into two distinct components: state of health (SOH) representing the current deterioration state, and deterioration rate representing the speed of deterioration. This segmentation allows the system to provide comprehensive information without overwhelming complexity, as each component can be processed and presented separately.
Solution Approach 2:
The patent adds a new dimension to battery information by introducing deterioration rate as a temporal derivative dimension alongside the static SOH dimension. This transforms the information from a single-state snapshot to a dynamic progression metric, enabling users to understand not just where the battery is in its deterioration journey but how quickly it is moving toward degradation.
2Ease of operation
If deterioration rate information is added to help users understand driving habit impact, then user awareness improves, but information processing complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where deterioration rate information is continuously provided to users based on their driving patterns. This feedback loop enables users to understand the direct impact of their driving habits on battery health, allowing them to adjust behavior accordingly. The system processes driving pattern data, correlates it with deterioration rate changes, and presents this information to users in an actionable format.
Solution Approach 2:
The patent introduces an intermediary processing layer that bridges raw battery state data and user-understandable information. This intermediary component calculates deterioration rate from SOH changes, correlates it with driving patterns, and presents synthesized information that connects user actions to battery impact without exposing the underlying computational complexity.
3Measurement precision
If comprehensive state information and association information are acquired and processed, then accurate deterioration rate information is obtained, but data processing requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-establishing the association between battery state information and deterioration rate through prior measurements and data collection. Instead of processing all possible data in real-time, the system pre-processes and stores the relationships between various state parameters and their correlation with deterioration, enabling efficient real-time calculations with reduced data processing requirements.
