Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell charging systems inefficiently prepare for fast-charging conditions, often cooling battery cells to standard operating temperatures, which counteracts the benefits of fast-charging and unnecessarily consumes resources.
Innovation Solution
A system and method for early identification of impending fast-charge events, allowing the battery cells to be pre-conditioned to optimal temperatures above standard operating temperatures for efficient fast-charging, utilizing a prediction system and environmental control to adjust temperatures accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery cells are cooled to standard operating temperature during operation, then battery reliability is improved, but fast-charging efficiency deteriorates
Solution Approach 1:
The system performs preliminary identification of upcoming fast-charge events and pre-heats battery cells before fast-charging occurs. The charge prediction system detects impending fast-charge opportunities, and the environment control system responds by heating cells to optimal temperatures in advance, so that when fast-charging begins, cells are already prepared for efficient charging without needing cooling first.
2Stability of the object's composition
If battery cells are cooled during operation, then operating temperature stability is improved, but resource consumption increases
Solution Approach 1:
The system uses periodic monitoring of charge events and conditional temperature adjustment. Instead of continuous cooling, the system periodically assesses upcoming charge events and only activates heating when fast-charging is predicted, creating an on-demand periodic action that reduces continuous resource consumption while maintaining temperature stability when needed.
3Use of energy by moving object
If standard operational profile is used for temperature control, then energy efficiency is improved, but fast-charge preparation capability deteriorates
Solution Approach 1:
The system dynamically switches between operational profiles based on predicted charge events. The manager selects between a standard operational profile (for normal conditions) and a fast-charge preparation profile (when fast-charging is predicted). This dynamic adaptation allows the system to maintain energy efficiency during standard operation while becoming highly adaptable when fast-charge opportunities arise.
