Grid Alert Control for EV Charging Peak Demand Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing adoption of electric vehicles poses challenges in managing their charging loads on the electric grid, leading to peak demand conditions and oversupply issues that can overwhelm the grid infrastructure.
Innovation Solution
A grid alert system that communicates with electric vehicles and charging stations to manage charging operations dynamically, adjusting load conditions by pausing, starting, or reversing charging based on grid demand and supply conditions, using a fleet of vehicles as a dynamic load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If electric vehicles are widely adopted and charged simultaneously, then the number of electric vehicles increases, but peak demand conditions overwhelm the grid infrastructure
Solution Approach 1:
The system implements periodic charging schedules for electric vehicles, distributing charging loads across different time periods rather than simultaneous charging. This temporal distribution prevents peak demand overload while accommodating a large fleet of vehicles, directly resolving the contradiction between increasing vehicle numbers and managing grid power capacity.
2Productivity
If charging operations are increased to meet vehicle demand, then more vehicles are charged, but oversupply issues arise that can overwhelm the grid infrastructure
Solution Approach 1:
The system continuously monitors grid conditions and uses this feedback to dynamically adjust charging operations. When grid stability thresholds are approached, the system modulates or pauses charging to prevent oversupply issues, while resuming or increasing charging when conditions permit. This closed-loop control maintains both high charging productivity and grid reliability.
3Adaptability or versatility
If dynamic control of charging operations is implemented, then load conditions are optimized, but system complexity increases
Solution Approach 1:
The system enables electric vehicles and charging stations to autonomously manage their own charging operations based on pre-established rules and real-time grid condition data. Vehicles can self-adjust charging schedules, and charging stations can autonomously modulate power delivery, reducing the need for complex centralized control while maintaining high adaptability to grid conditions.

AI summary
Systems and methods for performing actions in response to charging events, such as charging events associated with a specific electric vehicle and/or a specific charging station, are described. In some embodiments, the systems and methods may receive a request from an electric vehicle to identify a charging station from which to charge a battery of the electric vehicle, provide information associated with the electric vehicle to one or more charging stations proximate to the electric vehicle, receive from the one or more charging stations information identifying parameters associated with potential charging events provided by the one or more charging stations, and provide the information identifying the parameters associated with potential charging events provided by the one or more charging stations to the electric vehicle.
