Battery Pack Charging Control With Guideline Override Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery charging systems do not effectively control charging based on optimal charging behaviors, leading to sub-optimal charging patterns that can decrease the productivity and useful life of battery packs.
Innovation Solution
A charging control system that includes contactors to control current flow and a controller to receive charging information from a battery management system. The controller compares this information to charging guidelines and requests operator input if charging would violate these guidelines, allowing for optimal charging decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If charging is allowed at operator discretion without control, then ease of operation is improved, but battery health and useful life deteriorate due to sub-optimal charging patterns
Solution Approach 1:
The charging control system implements feedback by monitoring charging information from the battery management system, comparing it against charging guidelines, and providing real-time feedback to the operator through warnings or notifications when sub-optimal charging patterns are detected, thereby guiding operators toward optimal charging behavior without completely restricting their control
Solution Approach 2:
The system enables self-service by allowing operators to initiate charging when needed while automatically providing guidance through the charging guidelines and warnings, enabling operators to make informed decisions about when to charge without requiring expert knowledge or constant system intervention
2Reliability
If charging control based on charging guidelines is implemented, then battery health is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The charging control system leverages the existing battery management system to perform multiple functions: it not only manages basic battery charging operations but also monitors charging patterns, compares them against guidelines, and provides guidance, thereby implementing comprehensive charging optimization without requiring entirely separate control systems
Solution Approach 2:
The system applies preliminary action by pre-establishing charging guidelines based on optimal battery health parameters before charging operations begin. These guidelines are prepared in advance and automatically applied during charging, eliminating the need for complex real-time calculations and decision-making algorithms
Data Source
AI summary
A controller may receive, prior to initiation of charging of a battery pack by a charging unit, charging information relating to the battery pack. The controller may identify, in accordance with a comparison of the charging information to charging guidelines, whether charging the battery pack is to comply with the charging guidelines. The controller may output, responsive to identifying that charging the battery pack is to violate the charging guidelines, a request for an operator input to indicate whether charging the battery pack is to be initiated. The controller may cause initiation of charging of the battery pack responsive to the operator input indicating that charging is to be initiated.
