Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems struggle to efficiently manage charging requests from a large number of electric vehicles entering and leaving a smart city, leading to potential power shortages.
Innovation Solution
A charging control system comprising a charging control apparatus that calculates the number of electric vehicles in a smart city using various methods, determines a charging amount based on vehicle data, and performs charging control to optimize power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging apparatus stores electric power in advance, then power supply reliability is improved, but device complexity increases
Solution Approach 1:
The charging system is divided into multiple charging apparatuses distributed across different locations in the smart city. Each charging apparatus independently stores and supplies power, reducing the complexity of any single device while collectively ensuring power supply reliability through spatial distribution and load balancing.
2Productivity
If charging control apparatus calculates vehicle numbers and manages charging, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
A charging control apparatus acts as an intermediary between charging apparatuses and electric vehicles. It calculates the number of vehicles in the smart city, determines optimal charging amounts for each apparatus, and coordinates power distribution. This centralized control logic improves charging efficiency by preventing power shortages while keeping individual charging apparatuses relatively simple.
3Adaptability or versatility
If charging stand supplies power to multiple vehicles, then service coverage is improved, but power supply reliability deteriorates
Solution Approach 1:
The system segments power supply responsibilities across multiple charging apparatuses. When a charging stand needs to serve multiple vehicles, different charging apparatuses can independently supply power to different vehicles, preventing any single point of failure and maintaining power supply reliability while expanding service coverage.
