Charging Scheduling System for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle owners face high charging costs and inconvenience due to peak electricity pricing, as they must wait for price discounts, which also contributes to increased power consumption pressure during peak hours.
Innovation Solution
A charging scheduling system that automatically determines lower electricity price periods using electricity rate data and schedules charging accordingly, integrating a cloud management module with a charging device that includes a battery detection unit and network connection, allowing for optimized charging times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the home charger charges the electric vehicle immediately when connected, then the charging process starts without user waiting, but the charging fee is high due to peak electricity pricing
Solution Approach 1:
The system performs preliminary actions by detecting connection in advance and pre-scheduling the charging task to start during off-peak hours. The charging controller receives connection detection information and automatically schedules charging for lower-cost periods, eliminating the need for users to manually time their charging while still achieving cost savings.
2Loss of energy
If users wait for price discount periods to charge, then the charging cost is reduced, but users must spend much time and energy to wait and manually connect the vehicle
Solution Approach 1:
The charging system provides self-service functionality by automatically detecting vehicle connection, determining optimal charging schedules based on electricity pricing, and executing charging without user intervention. The charging controller autonomously manages the entire process, freeing users from manual connection and waiting tasks while achieving cost-effective charging.
3Ease of operation
If most electric vehicles charge at peak time, then users have immediate access to charging, but power consumption pressure increases during peak hours
Solution Approach 1:
The system implements periodic action by distributing charging loads across different time periods. Instead of concentrating all charging during peak hours, the charging controller schedules vehicles to charge during off-peak periods when electricity demand is lower, creating a more balanced and sustainable power consumption pattern across the grid.

AI summary
Charging scheduling systems and methods for charging devices applied to at least one charging device and a cloud management module are provided for charging an electric vehicle. First, a power status of a battery module of the electric vehicle is detected through a battery detection unit of the charging device, and electricity rate data corresponding to the charging device including the electricity price of corresponding power company at different times is then obtained by cloud management module. Next, through cloud management module, at least one charging period with a lower electricity price is determined based on electricity rate data corresponding to charging device and power status to control the charging of the electric vehicle by the charging device to be performed during the determined charging period.
