Solution Overview
Problem
Electric vehicle charging systems face challenges in reducing energy waste and maintaining grid stability, particularly when multiple charging stations draw power from a single electric grid, leading to frequency fluctuations and potential grid failures.
Innovation Solution
A system incorporating a battery storage system and a power delivery station configured to detect grid failures, using an electric vehicle recharging component for trickle charging to stabilize the grid by delivering power from an electric vehicle's battery storage system to the grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electric vehicle recharging stations draw power from a singular electric grid, then electric vehicles can be charged relatively quickly, but it imposes tremendous problems on grid stability due to frequency fluctuation
Solution Approach 1:
The patent introduces a battery storage system as an intermediary between the electric grid and multiple charging stations. This mediator buffers the power flow, allowing rapid charging of vehicles while preventing direct frequency fluctuations from reaching the grid. The battery system absorbs and releases power as needed, decoupling the charging demand from the grid's frequency stability.
Solution Approach 2:
The battery storage system performs preliminary energy storage during periods of low demand or excess generation, preparing energy reserves in advance. This allows the system to quickly discharge power during peak charging times without causing grid instability, effectively anticipating and preparing for power demand fluctuations before they occur.
2Quantity of substance
If multiple electric vehicle recharging stations are using power sourced from a singular electric grid, then charging capacity is increased, but it leads to tremendous problems on grid stability
Solution Approach 1:
The patent segments the power delivery system into multiple independent components: the electric grid, battery storage systems at each charging station, and the charging stations themselves. This segmentation allows each charging station to have local energy buffering capacity, enabling high power delivery capability while isolating grid stability issues to local levels rather than affecting the entire grid system.
3Loss of energy
If electric charging grids and stations charge more than just electric vehicles, then energy waste is reduced, but grid stability problems persist when multiple stations draw from a singular grid
Solution Approach 1:
The battery storage systems are designed with multi-functionality, serving both electric vehicle charging and general power grid stabilization purposes. These universal energy storage units can charge vehicles, provide backup power during grid failures, and perform frequency regulation, thereby reducing energy waste while maintaining grid stability through their versatile operational capabilities.
