Solution Overview
Problem
The expansion of the EV market is hindered by the limitations of conventional EV charging infrastructure, which requires extensive planning, high costs, and reliance on existing electrical grids, leading to inconsistent power supply, high costs, and long lead times for installation, especially in remote or seasonal locations, and is not environmentally friendly.
Innovation Solution
A portable charging station that can be quickly deployed and operates independently of the electrical grid, using a generator fueled by external supplies like gas or renewable energy sources, with modular charging dispensers and auxiliary power components, allowing flexible and strategic location based on need.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional EV charging stations are installed, then reliable power supply is achieved, but installation time and infrastructure costs increase significantly
Solution Approach 1:
The charging station is divided into separate functional modules: a portable charging unit with integrated generator and charging equipment, and a separate infrastructure component (electrical connection). This allows the charging function to be deployed independently without waiting for complete infrastructure installation, reducing installation time while maintaining operational reliability
Solution Approach 2:
A portable generator serves as an intermediary power source between the fuel supply and the EV battery. This intermediary enables charging operations to proceed independently of the main electrical grid, eliminating the need for lengthy infrastructure installation while ensuring reliable power supply through on-site power generation
2Reliability
If conventional EV charging stations are installed, then power supply is established, but infrastructure costs and complexity increase
Solution Approach 1:
The power generation function is extracted from the fixed infrastructure and integrated into the portable charging unit itself. By taking out the generator and placing it within the mobile charging station, the system eliminates dependence on external electrical grid infrastructure, reducing both installation complexity and ongoing infrastructure requirements while maintaining reliable power supply
Solution Approach 2:
The portable charging station is designed as a multi-functional unit that combines fuel storage, power generation, and EV charging capabilities in a single deployable system. This universal design allows the same unit to serve multiple locations without requiring location-specific infrastructure installation, reducing overall system complexity while ensuring power supply availability
3Productivity
If portable charging station with generator is used, then rapid deployment is achieved, but energy consumption and operating costs increase
Solution Approach 1:
The system allows flexible adjustment of operating parameters including fuel type selection (diesel, gasoline, natural gas, or renewable fuels), power output levels, and charging rates. By optimizing these parameters based on specific operational requirements and fuel availability, the system achieves rapid deployment while managing energy consumption and operating costs through efficient generator operation and appropriate power level selection

AI summary
A system for charging electric vehicles (EVs) includes a generator powered by a fuel supply, a charging dispenser configured to electrically connect with the EVs to charge the EVs via a power output from the generator, and an auxiliary power circuit electrically connected with the generator and including a power conductor that is configured to provide a first circuit path and a second circuit path adapted for connection to a first additional power source and a second additional power source, respectively. The power conductor is further configured to selectively power auxiliary components of the system via one of the generator, the first circuit path, or the second circuit path.
