Vehicle Power Transfer Selection by Capacity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles with small energy storage capacity are unable to provide sufficient balancing power, leading to the need for a large number of vehicles to be connected to the power network, which complicates power demand management.
Innovation Solution
A power transfer system that utilizes a managing server to select vehicles with sufficient remaining and rechargeable capacity to connect to the power network for power transfer, allowing them to balance power supply and demand, thereby reducing the number of vehicles required for power transfer capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If vehicles with small energy storage capacity are used for power transfer, then the number of vehicles required increases, but the system complexity and management difficulty increase
Solution Approach 1:
The patent changes the selection criterion from simply accepting any vehicle to selecting vehicles based on specific parameters: remaining capacity and rechargeable capacity. By setting minimum thresholds for these parameters, the system ensures each selected vehicle can provide sufficient balancing power, thereby reducing the total number of vehicles needed while simplifying management.
2Power
If vehicles with large energy storage capacity are selected, then sufficient balancing power is provided, but the selection criteria and management become more stringent
Solution Approach 1:
The patent defines specific parameter thresholds (remaining capacity ≥ first threshold, rechargeable capacity ≥ second threshold) to balance power provision capability with selection flexibility. This quantitative approach allows the system to maintain adaptability by accepting vehicles that meet the criteria while ensuring sufficient balancing power.
Solution Approach 2:
The managing server continuously monitors and acquires information about vehicle battery states (remaining capacity and rechargeable capacity), using this feedback to dynamically select appropriate vehicles for power transfer. This feedback mechanism ensures the system adapts to changing vehicle availability while maintaining power balancing effectiveness.
3Reliability
If a large number of vehicles are connected to the power network, then power supply and demand can be balanced, but the management overhead and system coordination increase
Solution Approach 1:
By changing the selection approach from quantity-based to capacity-based criteria, the patent reduces the number of vehicles needed while maintaining or improving power supply stability. Each selected vehicle contributes more effectively due to meeting minimum capacity thresholds, thereby reducing management overhead.
