EV Charging Reservation System for Wait Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle charging systems face interoperability issues between different networks, low utilization of charging infrastructure, and unpredictability due to first-come-first-served models, leading to long wait times and inefficient use of resources.
Innovation Solution
A method and system for scheduling reserved and ad-hoc charging sessions through a centralized reservation system, integrating with Electric Vehicle Service Equipment (EVSE) to manage charging sessions, improve user experience, and optimize infrastructure utilization by allowing users to reserve and manage charging sessions across various networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a first-come-first-served model is used for charging sessions, then the system is simple to operate, but wait times become unpredictable and infrastructure utilization is low
Solution Approach 1:
The system allows users to reserve charging sessions in advance by selecting desired time slots and EVSEs. The reservation is confirmed before the user arrives, eliminating unpredictable wait times while maintaining simple operation through a user-friendly interface.
2Productivity
If charging sessions are reserved in advance, then wait times are reduced and infrastructure utilization is optimized, but the system complexity increases
Solution Approach 1:
The centralized reservation system serves multiple functions: it manages reservations, handles check-ins, coordinates with EVSEs, and provides user notifications. By consolidating these functions into a single multi-functional platform, the system achieves high infrastructure utilization without proportionally increasing complexity.
Solution Approach 2:
The reservation system acts as an intermediary between users and EVSEs, managing the coordination and communication. This mediator approach simplifies the overall system architecture by centralizing control logic while maintaining simple interfaces for both users and EVSEs.
3Adaptability or versatility
If different charging networks operate independently, then each network can optimize its own operations, but interoperability between networks is poor
Solution Approach 1:
The reservation system is designed to work across multiple charging networks simultaneously. It can manage reservations for different EVSEs from different networks through a unified interface, enabling users to access any network's infrastructure while each network maintains its operational independence.

AI summary
Embodiments of a method and/or system for charging one or more electric vehicles (e.g., based on one or more reserved charging sessions; for charging an electric vehicle during a scheduled time period; etc.) can include: receiving a reservation request (e.g., a reservation request including one or more reservation parameters; etc.); scheduling a reserved charging session based on the reservation request (e.g., based on reservation parameters from the reservation request; etc.); determining a check in at an Electric Vehicle Service Equipment (EVSE) for the reserved charging session; and/or causing the EVSE to charge the electric vehicle based on the reserved charging session (e.g., during the scheduled time period; etc.).
