Electric Vehicle Battery Segmentation for External Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electric vehicles lack clear information on how much electricity to feed from their battery to external facilities, as existing systems do not provide a clear breakdown or notification of the available electricity for feeding.
Innovation Solution
A vehicle equipped with an electronic control unit that divides the stored electricity into amounts for traveling and feeding, and notifies the user of this information, allowing for external charging and feeding while ensuring the user understands how much electricity can be safely fed to external facilities, including facilities that demand electricity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery feeds electricity to external facilities, then external electricity demand is met, but the user lacks clear information on how much electricity should be fed
Solution Approach 1:
The patent segments the total stored electricity information into distinct components: electricity amount for traveling and electricity amount for feeding. This segmentation is achieved through the control unit that calculates and displays these separate values, allowing users to clearly understand how much electricity is available for external feeding without compromising travel requirements.
2Loss of information
If the vehicle provides detailed electricity information, then user understanding improves, but system complexity increases
Solution Approach 1:
The control unit performs multiple functions: it manages motor control, calculates stored electricity amount, determines electricity amount for traveling, calculates electricity amount for feeding, and displays this information to the user. By consolidating these diverse functions into a single control unit, the patent provides comprehensive electricity information without significantly increasing overall system complexity.
