Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles face challenges in efficiently allocating power between internal operations and external devices, particularly when high-power devices like motors start up, leading to potential power shortages.
Innovation Solution
A vehicle system that monitors and adjusts power allocation by staggering startup times and using additional power sources when needed, based on device states and projected usage, to ensure sufficient power is available for both internal propulsion and external device operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle provides power to multiple external devices simultaneously, then the utility and productivity of the vehicle as a power source is improved, but power shortages occur when high-power devices start up
Solution Approach 1:
The control module monitors the operational states of external devices and predicts power requirements before high-power devices start up. By performing preliminary power allocation adjustments based on predicted demand, the system prevents power shortages before they occur, ensuring stable power supply while maintaining high productivity
Solution Approach 2:
The patent implements dynamic power allocation where the control module continuously adjusts power distribution to external devices based on real-time operational states, device priority levels, and predicted power requirements. This dynamic adjustment capability allows the system to maintain reliable power supply while supporting multiple devices simultaneously
2Reliability
If the vehicle prioritizes power to running devices, then power supply reliability is improved, but charging efficiency of recharging devices deteriorates
Solution Approach 1:
The control module changes power allocation parameters dynamically based on device states. When a recharging device reaches a predefined charge level threshold, the system adjusts power distribution parameters to reduce or stop charging that device, thereby improving overall charging efficiency while maintaining reliable power supply to running devices
Solution Approach 2:
The system implements feedback mechanisms by monitoring the charge levels of recharging devices and using this information to adjust power allocation. The control module receives feedback on device states and continuously optimizes power distribution to balance reliability and charging efficiency
3Ease of operation
If the vehicle uses internal battery power for external devices, then ease of operation is improved, but the traction battery charge depletes
Solution Approach 1:
The patent enables the vehicle's power system to serve multiple functions: propelling the vehicle and providing power to external devices. The control module intelligently manages the power source, selecting between traction battery and auxiliary battery based on vehicle needs, thereby maintaining ease of operation while conserving traction battery charge for propulsion
