Portable EV Charger Dispatch for Range Anxiety Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing EV charging infrastructure is inadequate, particularly in rural areas, leading to range anxiety and inefficiencies, with existing technologies being expensive and time-consuming, and there are not enough charging stations to meet the growing number of EV drivers, necessitating a more efficient and flexible charging solution.
Innovation Solution
A movable power vehicle charging (MPVC) service system that analyzes EV data to schedule and manage portable electric vehicle charger (PEVC) unit deliveries through IoT data analysis, assigning carriers to deliver PEVC units to end users, enabling ride-sharing and optimal charging solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed charging stations are deployed to meet EV charging demand, then charging reliability is improved, but infrastructure cost and deployment complexity increase significantly
Solution Approach 1:
The patent transforms the static fixed charging station model into a dynamic mobile charging vehicle system. The charging service moves with the user rather than requiring the user to move to a fixed station, fundamentally changing the system from infrastructure-centric to vehicle-centric charging delivery.
Solution Approach 2:
The mobile charging vehicle acts as an intermediary between the power grid and the EV user. It carries charging equipment and power supply components to provide charging services at any location, eliminating the need for fixed infrastructure at the user's destination.
2Adaptability or versatility
If more fixed charging stations are built to serve growing EV numbers, then charging accessibility is improved, but deployment time and cost increase
Solution Approach 1:
The system enables charging accessibility to dynamically adapt to user needs rather than requiring predetermined fixed station locations. The mobile charging vehicle can be dispatched to any location within its operational range, providing flexible and on-demand charging service.
Solution Approach 2:
The mobile charging vehicle is pre-equipped with charging equipment, power supply components, and necessary tools before deployment. This preliminary preparation allows rapid response to charging requests without requiring time-consuming on-site infrastructure installation.
3Reliability
If fixed charging stations are densely deployed to eliminate range anxiety, then user confidence is improved, but system cost and maintenance burden increase
Solution Approach 1:
The mobile charging vehicle serves multiple functions: it provides charging services, carries power supply equipment, and can operate at various locations. This multi-functionality reduces the need for numerous dedicated fixed stations, as one mobile unit can serve multiple users and locations sequentially.
Solution Approach 2:
The system recovers and reuses charging equipment and power supply components across multiple service deliveries. Instead of dedicating infrastructure to each charging event, the mobile vehicle transports and redeploys the same equipment to different locations, maximizing resource utilization.
Data Source
AI summary
A computer-implemented method for receiving electric vehicle (EV) data describing at least one connected electric vehicle and at least one portable electric vehicle charging (PEVC) unit and analyzing the received data to determine at least one PEVC demand requirement and at least one PEVC ride-sharing supply. The method may further include assigning an identified PEVC carrier to deliver a PEVC unit to a target PEVC end user and transmitting at least one delivery instruction to the assigned PEVC carrier and the target PEVC end user. The method may further include receiving a confirmation message from the assigned PEVC carrier that the PEVC unit was delivered to the target PEVC end user.
