Power Flow Routing for Daisy-Chained EV Charging Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charge point anxiety arises from electric vehicles blocking charging points, as existing solutions for sharing charge points do not guarantee access and require complex brokerage systems.
Innovation Solution
An apparatus and system that redirect power flow between multiple devices, allowing electric vehicles and other electrically powered devices to be connected in a daisy chain configuration, using a computing device to manage power distribution and implement protocols for secure and efficient charging, including a token-based system for access and payment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electric vehicles are connected to charge points, then charging function is provided, but charge points are blocked and access for other vehicles is reduced
Solution Approach 1:
The patent segments the charging function by introducing intermediary devices (power banks, portable charging units) that can be connected to the charge point and then used to charge electric vehicles. This segmentation allows the charge point to serve multiple vehicles sequentially through different intermediary units, preventing blocking while maintaining charging productivity.
Solution Approach 2:
The patent employs intermediary devices such as power banks and portable charging units that act as mediators between the charge point and the electric vehicle. These intermediaries receive power from the charge point and transfer it to the vehicle, enabling the charge point to be shared among multiple vehicles without any single vehicle blocking direct access.
2Adaptability or versatility
If charge points are shared among multiple vehicles, then access is improved, but existing solutions require complex brokerage systems and do not guarantee access
Solution Approach 1:
The patent implements self-service mechanisms where users can directly access and use portable charging units or power banks without requiring complex brokerage intermediaries. The system provides automated access control, booking, and power distribution through user-friendly interfaces, eliminating the need for complex manual coordination while guaranteeing access through reserved time slots and dedicated charging units.
3Productivity
If multiple devices are connected in daisy chain configuration, then power distribution efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments the power distribution system into modular units that can be connected in daisy-chain configurations. Each unit is independently functional and can operate autonomously, reducing the complexity burden of the overall system. The modular design allows easy addition or removal of units without reconfiguring the entire system, maintaining simplicity while achieving efficient power distribution across multiple devices.
