Vehicle Sensor Battery Charging Based on Destination Monitoring Need
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems face inefficiencies in charging sensor batteries for external monitoring when the vehicle is deactivated, especially when the destination does not require prolonged monitoring, leading to unnecessary resource usage.
Innovation Solution
A computer system within the vehicle determines the state-of-charge (SOC) of the sensor battery and schedules charge intervals during travel to the destination based on the risk parameter at the planned destination, optimizing charging during efficient engine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor battery is charged continuously during vehicle travel, then the battery state-of-charge is maintained sufficient for sensor operation, but unnecessary energy is consumed when the destination does not require prolonged monitoring
Solution Approach 1:
The system determines the risk parameter at the planned destination in advance and schedules charge intervals during travel based on this predetermined information. By knowing the destination's risk level before arrival, the system can proactively charge the sensor battery only during travel segments leading to high-risk destinations, avoiding unnecessary charging at low-risk destinations.
Solution Approach 2:
Instead of continuously charging the sensor battery throughout the entire vehicle operation, the system applies partial charging action by scheduling charge intervals selectively based on the destination risk parameter. This partial action approach charges the battery only when and where it is actually needed, rather than applying excessive charging action universally.
2Loss of energy
If the sensor battery is charged during inefficient engine operation, then the battery is recharged, but vehicle fuel efficiency deteriorates
Solution Approach 1:
The system schedules charge intervals during travel segments based on predetermined route information and engine efficiency data. By planning charge intervals in advance during efficient engine operation periods, the system ensures battery recharging occurs without compromising overall vehicle fuel efficiency.
Solution Approach 2:
The system dynamically adjusts charge interval scheduling based on real-time engine operation efficiency. Charge intervals are scheduled during travel segments when the engine operates efficiently, and the system monitors and adapts to changing engine conditions to maintain optimal fuel efficiency while ensuring battery charge needs are met.

AI summary
A system can include a computer coupled to a memory storing instructions to determine an upcoming interval for operating a sensor at a planned destination and to determine an upcoming duration for travel to the planned destination. In response to determining that a battery coupled to the sensor includes a state-of-charge (SOC) that is insufficient to operate the sensor for the upcoming interval, programming of the computer can schedule a charge interval during vehicle travel to the planned destination and actuate the battery charging according to the scheduled charge interval during the vehicle travel.
