Solution Overview
Problem
Traditional EV charging systems require hardwiring to an electrical grid, making it difficult and costly to efficiently expand or adjust charging infrastructure as needs change.
Innovation Solution
A multi-vehicle self-contained EV charging platform that utilizes a solar array to generate electricity, a charging system capable of Level 1, 2, or 3 charging, and a charge distribution system to stabilize and distribute power among multiple vehicles, along with a weighted base assembly for stability and a sun tracking actuation system for optimal energy harvesting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional EV charging systems are hardwired to an electrical grid, then reliable power supply is ensured, but infrastructure expansion and adjustment become difficult and costly
Solution Approach 1:
The charging system is divided into modular components: solar panels, charge controllers, inverters, and charging stations that can be independently configured and deployed. This segmentation allows flexible expansion from single-unit to multi-vehicle configurations without requiring extensive grid infrastructure.
Solution Approach 2:
The charging platform serves multiple functions: generating power via solar panels, storing energy in batteries, distributing charge to multiple vehicles simultaneously or sequentially, and operating independently from the electrical grid. This multi-functionality replaces the need for separate grid connection infrastructure.
2Ease of operation
If solar arrays are used to generate electricity off-the-grid, then infrastructure flexibility and ease of deployment improve, but power stability and consistency deteriorate
Solution Approach 1:
Energy is stored in advance in battery banks during periods of high solar generation or low demand, ensuring power availability during periods of low sunlight or high charging demand. This preliminary energy accumulation stabilizes the otherwise intermittent solar power supply.
Solution Approach 2:
The system dynamically adjusts operating parameters including charge distribution ratios among vehicles, inverter output settings, and battery charge/discharge rates to maintain stable power delivery despite variable solar input conditions.
3Productivity
If power is distributed to multiple vehicles simultaneously, then charging efficiency improves, but system complexity and power management difficulty increase
Solution Approach 1:
The charge distribution system continuously monitors battery levels, charging rates, and solar generation output for each connected vehicle, automatically adjusting power allocation to optimize overall charging efficiency while preventing any single vehicle from monopolizing available power.
Solution Approach 2:
The system transitions between different operational modes dynamically: simultaneous charging when power is abundant, round-robin sequencing when power is limited, and priority-based distribution when certain vehicles require urgent charging, adapting to real-time conditions.
