EV Power Allocation Routing for Blackout Supply Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively utilize the battery energies of scattered electric vehicles and balance demand and supply of electric power, especially during disasters, making it impossible to allocate electric vehicles as a supply side to demand sides requiring power.
Innovation Solution
A power information processing apparatus and method that guides and allocates electric vehicles as the supply side to demand sides based on generated route information, balancing demand and supply, prioritizing areas with high demand, and avoiding mismatches in vehicle-to-charger connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If electric vehicles are scattered in various places and not in operation, then the battery energies cannot be effectively used, but the system complexity increases when trying to manage and allocate these vehicles
Solution Approach 1:
The patent introduces a server as an intermediary that receives information from multiple electric vehicles and charging/discharging apparatus, processes allocation based on power supply/demand conditions, and generates route information. This intermediary coordinates the matching between vehicles and charging stations, enabling effective utilization of scattered battery energies without requiring direct complex interactions between all system components.
2Reliability
If electric vehicles are allocated to charging/discharging apparatus, then power supply can be balanced, but mismatches occur when the number of vehicles exceeds the number of chargers
Solution Approach 1:
The server receives information from both electric vehicles (including their power supply capabilities and locations) and charging/discharging apparatus (including their status and locations). Based on this feedback information about power supply/demand conditions, the server performs optimal allocation and generates route information, ensuring that the number of allocated vehicles matches the available charging/discharging capacity without mismatches.
3Measurement precision
If route information is generated to guide electric vehicles, then allocation accuracy improves, but the time required for processing and communication increases
Solution Approach 1:
The server performs allocation processing in advance by receiving information from electric vehicles and charging/discharging apparatus, calculating optimal routes, and generating route information before the vehicles need to be dispatched. This preliminary action ensures accurate allocation while minimizing the time required during actual emergency response or power supply operations.
