Solution Overview
Problem
The adoption of zero tail pipe emission technologies, such as all-electric vehicles, is hindered by high costs, limited driving range, and long recharging times, particularly in densely populated cities with limited financial resources, where existing solutions like collection, charging, and distribution machines are not conveniently located or affordable.
Innovation Solution
A portable charging device with a security system that includes a controller for authentication, communication, and tracking, allowing charging only after authentication via NFC, and regulating energy release to prevent unauthorized use, coupled with a network of collection, charging, and distribution machines strategically located at convenience stores or gas stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If collection, charging and distribution machines are deployed to enable battery swapping and charging, then recharging time is reduced and driving range is extended, but device complexity and infrastructure cost increase
Solution Approach 1:
The system divides the charging infrastructure into two distinct components: (1) stationary collection/charging/distribution machines that maintain battery inventory, and (2) portable charging devices that users can carry. This segmentation allows the complex infrastructure to be distributed and modular, reducing the burden on any single location while providing flexible charging access.
Solution Approach 2:
The portable charging device acts as an intermediary between the stationary charging machines and the user's battery. It receives authenticated charging requests, manages the charging process, and can be transported to wherever the user needs power. This intermediary simplifies the user experience while maintaining control over the charging infrastructure.
2Ease of operation
If portable charging devices are introduced for user mobility, then ease of operation is improved, but security risks and unauthorized use increase
Solution Approach 1:
The system performs authentication and authorization actions before allowing any charging operation. The controller verifies user credentials, checks device compatibility, and establishes charging parameters in advance. This preliminary action ensures that only authorized users can access the charging function, preventing unauthorized use while maintaining ease of operation for legitimate users.
Solution Approach 2:
The controller continuously monitors the charging process and communicates with the portable charging device to verify ongoing authentication status. If unauthorized access is detected or credentials expire, the system immediately terminates the charging operation. This feedback mechanism maintains security control while allowing seamless operation for authenticated users.
3Reliability
If authentication and tracking systems are implemented in portable charging devices, then reliability and usage monitoring are improved, but device complexity increases
Solution Approach 1:
The controller in the portable charging device is designed to perform multiple functions: authentication verification, charging parameter management, usage tracking, and communication with both the stationary charging machines and the user's battery. By consolidating these functions into a single multi-functional controller, the system achieves high reliability without proportionally increasing complexity.
Solution Approach 2:
The system merges the authentication, tracking, and control functions into an integrated security system that operates as a unified module. The controller combines credential verification, charging management, and data logging capabilities in one component, reducing overall system complexity while maintaining comprehensive security and monitoring capabilities.

Data Source
AI summary
A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. Users may also use portable charging devices that authenticate portable electrical energy storage devices or are authenticated by portable electrical energy storage devices before the charging is allowed or enabled. This authentication may be via wired or wireless communication channels between the portable charging device and portable electrical energy storage device, such as via near field communication (NFC) channels.
