Telematics Battery Backup for Fleet Data Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telematics systems in fleet management rely on vehicle power, leading to interruptions and inaccuracies when power is lost or unstable, such as when the telematic monitoring device is unplugged or the connection with the vehicle is poor, causing disruptions in data collection and communication.
Innovation Solution
A battery backup system with control circuitry that operates in multiple modes to provide power to telematic monitoring devices, including full power and low power modes, and disconnects power when not needed, using sensors to determine vehicle state and motion to manage power distribution effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telematic monitoring device relies on vehicle power, then device operation is simple and integrated with vehicle system, but data collection is interrupted when vehicle power is lost or connection is poor
Solution Approach 1:
The power supply system is segmented into two independent sources: vehicle power source and battery power source. The battery device is separated as an independent backup unit with its own control circuitry, allowing the telematic monitoring device to switch between power sources without requiring complete system redesign, thus improving reliability while managing complexity.
Solution Approach 2:
The battery device acts as an intermediary power source between the vehicle power system and the telematic monitoring device. It includes control circuitry that mediates power flow decisions, determining when to charge from the vehicle and when to discharge to the monitoring device, thereby ensuring continuous operation during power transitions.
2Reliability
If battery backup is always active, then power continuity is ensured, but energy is wasted when vehicle power is available
Solution Approach 1:
The battery device operates dynamically with multiple selectable modes (first mode, second mode, third mode) that adjust its function based on real-time vehicle power availability. The control circuitry continuously monitors vehicle power status and switches between charging mode, standby mode, and power supply mode, optimizing energy usage while ensuring power continuity when needed.
Solution Approach 2:
The control circuitry implements feedback control by monitoring vehicle power status and battery charge levels. Based on this feedback, the system automatically adjusts battery operation - charging when vehicle power is available and stable, and switching to battery power when vehicle power is lost or unstable, thereby preventing energy waste while maintaining reliability.
3Reliability
If battery charges continuously from vehicle, then battery is always ready for backup, but battery may overcharge when vehicle power is unstable
Solution Approach 1:
The control circuitry monitors vehicle power stability through feedback mechanisms and adjusts charging operations accordingly. When vehicle power is detected as unstable or fluctuating, the control circuitry prevents charging operations, thereby protecting the battery from overcharge damage while still maintaining readiness for backup power supply when conditions are favorable.
