Vehicle Load Power Control for Parking Dark Current Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is managing dark current in vehicles during parking, which leads to battery durability issues and potential start-up failures due to over-discharge, as existing technologies lack the ability to individually control electric field loads effectively.
Innovation Solution
A power control apparatus that includes switches, storage, and a controller to monitor and manage power supply to various loads, identifying and controlling which loads receive power during parking mode, thereby reducing dark current consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power is supplied to all electric field loads during parking mode, then user convenience is maintained, but dark current consumption increases causing battery over-discharge
Solution Approach 1:
The patent segments the power supply control by individual loads rather than controlling all loads collectively. Each load is independently monitored and controlled through its own switch, allowing selective power supply to only necessary loads during parking mode, thereby reducing dark current while maintaining user convenience for essential functions.
Solution Approach 2:
The patent applies different power supply states to different loads based on their individual characteristics and necessity. Essential loads receive continuous power while non-essential loads are powered down during parking mode, creating localized quality differences in power supply strategy to optimize both energy consumption and user convenience.
2Duration of action of stationary object
If dark current is reduced by cutting power to loads, then battery life is prolonged, but load functionality is lost
Solution Approach 1:
The patent implements dynamic power control where the power supply state of each load can change based on operational mode (driving mode vs. parking mode). Loads can be dynamically switched between powered and unpowered states, allowing the system to adapt power consumption to current operational requirements while preserving battery life during parking.
Solution Approach 2:
The controller automatically monitors and manages power supply to individual loads based on predetermined criteria without requiring manual user intervention. The system self-adjusts power distribution to optimize battery life while maintaining necessary load functionalities, performing the power management service autonomously.
3Loss of energy
If individual load control is implemented, then dark current management improves, but system complexity increases
Solution Approach 1:
The controller performs multiple functions including monitoring load operation states, determining parking mode, controlling individual load power supply, and managing switch states. This multi-functional approach consolidates what could be multiple separate control systems into a single controller, reducing overall system complexity while achieving individualized load management.
Solution Approach 2:
The patent combines the power control functionality for multiple individual loads into a unified control system centered around a single controller and storage unit. Rather than implementing separate control circuits for each load, the system merges control functions to manage dark current effectively while minimizing the increase in system complexity.
