EV Battery Charging Control for Personalized Time, Range, and Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle charging systems lack the ability to provide personalized smart charging options based on user demands, such as charging time, mileage, and cost, resulting in users being passive recipients of charging services rather than active participants in managing their charging schedules.
Innovation Solution
A battery charging method and system that allows users to input specific charging demand parameters, which are then used to calculate a target charging scheme considering actual battery operation state information, enabling personalized charging that meets user-defined requirements, including charging time, mileage, and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional charging piles are used, then charging function is provided, but users cannot obtain personalized charging services according to their own demands
Solution Approach 1:
The charging system is segmented into multiple independent modules: user information acquisition module, parameter calculation module (charging time, mileage, electricity amount), scheme generation module, and execution module. This segmentation allows the system to provide personalized charging services by processing different user demands through separate functional blocks, improving adaptability while managing complexity through modular design.
2Loss of time
If charging time is reduced, then user efficiency is improved, but battery lifetime may be affected
Solution Approach 1:
The system dynamically adjusts charging parameters based on real-time battery state and user requirements. The calculation module determines optimal charging curves that balance charging speed with battery health protection, allowing the charging rate to vary during the process rather than maintaining a fixed high rate, thus reducing charging time while preserving battery lifetime.
Solution Approach 2:
The system changes charging parameters (current, voltage, temperature thresholds) based on battery state of charge and user demands. By dynamically modifying these parameters during charging, the system achieves faster charging when appropriate while implementing protective parameter adjustments when battery health is at risk, resolving the contradiction between charging time and battery lifetime.
