Vehicle Battery Charge Management via Power Save Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle manufacturing process often results in vehicle batteries being partially or fully discharged due to unnecessary load drainage during quality checks and storage periods, lacking effective means to aggressively manage and preserve battery state of charge.
Innovation Solution
A system and method that monitor vehicle conditions to activate a power save mode by simulating an ignition off condition, using a monitoring module and control module to disconnect the battery from electrical systems when safety conditions are met and the vehicle is stationary, thereby limiting charge drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle undergoes normal quality checks and storage procedures, then the vehicle can be properly manufactured and stored, but the battery state of charge deteriorates due to continuous load drainage
Solution Approach 1:
The system performs preliminary actions by monitoring battery voltage and current draw before complete discharge occurs, and preemptively activates power save mode to prevent excessive discharge during manufacturing and storage operations
Solution Approach 2:
The system dynamically adjusts the vehicle's power consumption state by transitioning between normal operation mode and power save mode based on real-time monitoring of battery conditions, operational state, and environmental factors
2Ease of operation
If the vehicle electrical systems remain active during manufacturing and storage, then quality checks can be performed and vehicle systems remain ready, but unnecessary load continues to drain the battery
Solution Approach 1:
The system segments the vehicle's electrical systems into critical systems that must remain operational and non-critical systems that can be deactivated, allowing selective power management during manufacturing and storage operations
Solution Approach 2:
The system extracts unnecessary electrical loads from the active circuit by deactivating non-essential systems while maintaining power to critical components, thereby reducing overall power consumption without completely shutting down the vehicle
3Device complexity
If a simple timer solution is used to turn off loads, then the implementation is simple, but the battery charge is not aggressively preserved during manufacturing and storage
Solution Approach 1:
The system continuously monitors battery voltage, current draw, and operational conditions, using this feedback to dynamically adjust power consumption and activate power save mode when battery charge levels indicate risk of excessive discharge
Solution Approach 2:
The control module serves multiple functions by monitoring battery conditions, determining operational state, evaluating environmental factors, and controlling power save mode activation, consolidating these functions into a single intelligent control system
