Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional charging stations are installed at existing locations, then charging infrastructure availability increases, but significant site modifications and grid connections are required
Solution Approach 1:
The charging station is divided into modular components including a power conversion system module, battery module, and charging module that can be independently assembled and deployed. This segmentation allows the system to be installed at existing locations without requiring extensive grid modifications, as each module can be independently connected to available power sources.
Solution Approach 2:
The power conversion system is designed to accept multiple types of power inputs including grid power, renewable energy sources, and alternative power sources. This multi-functionality enables the charging station to operate at diverse locations with varying power infrastructure capabilities, eliminating the need for significant site-specific modifications.
2Reliability
If charging stations are designed for specific vehicle types, then charging efficiency improves, but compatibility with non-standard connectors is limited
Solution Approach 1:
The charging system incorporates multiple charging modules with different connector types and power conversion capabilities. The system can automatically detect and adapt to the connected vehicle type, providing reliable charging for standard EVs, non-standard connectors, and even non-vehicle applications through its universal design that supports various power inputs and output configurations.
Solution Approach 2:
The power conversion system dynamically adjusts its operating parameters based on the detected vehicle requirements and available power source. This dynamic adaptation allows the system to maintain high charging efficiency while accommodating a wide range of vehicle types and connector standards without requiring separate dedicated charging stations for each vehicle type.
3Reliability
If charging stations are permanently installed, then operational stability improves, but deployment speed and relocation capability decrease
Solution Approach 1:
The charging station uses modular segments that can be quickly assembled and disassembled while maintaining operational stability when deployed. The standardized connection interfaces ensure reliable electrical connections during operation, while the modular nature allows for rapid deployment and relocation without permanent installation, reducing both installation time and relocation time.
4Power
If grid-connected charging stations are used, then power supply capacity increases, but installation complexity and infrastructure requirements increase
Solution Approach 1:
The power conversion system is designed to accept multiple power inputs including grid power for high-capacity charging, renewable energy sources for sustainable operation, and alternative power sources for flexible deployment. This universal power acceptance capability provides high charging power capacity when grid connection is available while eliminating the requirement for complex grid modifications when deploying at existing locations with limited infrastructure.

AI summary
A modular and portable charging station according to various aspects of the present technology may include a main chassis body that is fully assembled at one location and then transferred as a whole to a desired location and placed into operation without the need for significant site modification, or connection to the electric power grid. The interior of the main chassis body may contain one or more removable charging stations and at least one removable battery bank. The battery bank provides each charging station with electrical power to charge a vehicle battery system. The portable charging station may comprise its own onboard power supply configured to use renewable sources to maintain a charge to the battery bank. The portable charging station may also be configured to be connected to a local power source that is connected to the local power grid. A power management system monitors the charge level of the battery bank and is able to select an appropriate method of recharge.
