EV Charging Server Control for Post-Reservation Grid Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in responding to power supply and demand balancing requests in predetermined power systems after a reservation slot for charging electrified vehicles has ended, making it difficult to effectively manage power control.
Innovation Solution
A server system that manages power control between a power controller and an electrified vehicle, which includes a communication unit to acquire information on power supply and demand balancing requests and processors to check during a reservation slot whether power control is executable after the slot, allowing for continuous execution of power control and adjusting the execution period based on various factors such as SOC limits, power exchange information, and user stay periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system only executes power control within the reservation slot, then the reservation management is simple, but the system cannot respond to power supply and demand balancing requests after the reservation slot ends
Solution Approach 1:
The server checks with the user during the reservation slot whether power control should be executed after the slot ends. This preliminary check enables the system to respond to power supply and demand balancing requests after the reservation slot while managing complexity through advance user confirmation.
2Ease of operation
If the system checks with the user after the reservation slot ends, then the user can make informed decisions, but the response time to power supply and demand balancing requests is delayed
Solution Approach 1:
The server checks with the user during the reservation slot (before it ends) whether power control should continue after the slot. This timing allows users to make informed decisions while ensuring the system can respond promptly to power supply and demand balancing requests when needed.
3Productivity
If the system allows power control execution after the reservation slot, then more users can participate in power control, but overlapping reservations and insufficient SOC problems occur
Solution Approach 1:
The server checks with the user during the reservation slot to obtain confirmation before executing power control after the slot ends. This feedback mechanism ensures users are aware of and agree to extended power control, preventing overlapping reservations and ensuring sufficient SOC by confirming user intent in advance.

AI summary
A server includes a communication unit configured to acquire information on a power supply and demand balancing request, and one or more processors configured to control power control in a reservation slot in which a reservation is made for the power control by a user of an electrified vehicle. The processors are configured to execute control to check, with the user during a period from a start of the power control in the reservation slot to a time immediately after an end of the power control, whether the power control responding to the power supply and demand balancing request is executable after the reservation slot.
