Vehicle Battery Unit Charging With Selective Pre-Departure Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for charging electric battery units in vehicles before departure often result in increased wear on the vehicle and battery units, leading to reduced durability and inefficient monitoring.
Innovation Solution
A method that wakes up the vehicle to a wake-up mode, sets it in a charging mode, connects a subset of electric battery units for charging, and checks the status, reducing wear by only charging a subset for monitoring and temperature checks, thereby improving the state of charge and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all electric battery units are connected and monitored before departure, then the state of charge can be ensured, but the wear on the vehicle and battery units increases
Solution Approach 1:
The patent divides the battery system into multiple individual battery units, each with its own controller. Instead of monitoring all units simultaneously, the system selectively activates and monitors only a subset of battery units before departure, segmenting the monitoring task to reduce overall wear while ensuring adequate charge status
2Reliability
If continuous monitoring of all battery units is performed, then the vehicle status can be ensured, but the overall wear on the vehicle increases
Solution Approach 1:
The patent implements partial monitoring by selecting only a subset of battery units for activation and status checking before departure. This partial action approach ensures adequate vehicle status monitoring without the excessive wear that would result from continuously monitoring all battery units, achieving sufficient reliability with reduced harm
