EV Power Control Incentives for Accommodation Facility Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accommodation facility management systems fail to effectively promote the use of facilities, leading to a low number of users, as they only select electricity use plans based on user behavior without providing clear incentives.
Innovation Solution
A power management device and system that acquires information on the power state of accommodation facilities and regions, requesting users of electrified vehicles to perform power control (such as external charging or power supply) and offering benefits when predetermined conditions are met, thereby encouraging frequent use and adjusting power states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only electricity use plan selection based on user behavior is implemented, then the system complexity is reduced, but the user motivation and accommodation facility usage increase
Solution Approach 1:
The patent introduces a power management device as an intermediary between the user's electrified vehicle and the accommodation facility. This mediator coordinates power control actions, manages benefit distribution, and orchestrates the interaction between vehicle-to-grid functionality and facility operations, thereby solving the complexity-usage contradiction by centralizing control logic in a dedicated intermediary system
Solution Approach 2:
The system implements feedback mechanisms where users receive information about their power control contributions and corresponding benefits. The power management device monitors power control actions, evaluates their impact on facility power state, and provides feedback to users through benefit allocation, creating a closed-loop system that motivates continued participation without requiring complex user-side decision-making
2Productivity
If benefits are provided to users for power control, then the accommodation facility usage increases, but the operational cost of the facility increases
Solution Approach 1:
The patent converts the operational cost burden into a benefit distribution mechanism. Instead of viewing power control incentives as pure expenses, the system frames them as returns on investment from power supply and demand adjustment requests. The power management device calculates benefits based on the value provided to the power system, transforming operational costs into compensated transactions that can be offset by revenue from grid services
Solution Approach 2:
The system dynamically adjusts benefit parameters based on power supply and demand conditions. The power management device modifies benefit amounts, types, and distribution timing according to real-time power state, facility needs, and grid conditions. This parameter flexibility allows the facility to optimize between user motivation and operational cost by scaling benefits according to actual power market value
3Reliability
If power control is requested from users, then the power state management improves, but the user operation complexity increases
Solution Approach 1:
The patent enables self-service power control where the user's electrified vehicle automatically performs power control actions based on requests from the power management device. The vehicle's onboard systems autonomously execute charging, discharging, or power supply operations without requiring manual user intervention, thereby maintaining high reliability in power state management while preserving ease of operation through automated vehicle-based execution
Solution Approach 2:
The power management device handles multiple functions universally: it manages power control requests, calculates benefits, communicates with the power system, monitors facility power state, and distributes incentives. By consolidating these diverse functions in a single multi-functional device, the system achieves reliable comprehensive power state management without requiring users to navigate complex separate control interfaces for each function
Data Source
AI summary
The server (power management device) is a power management device that acquires information on a power state of an accommodation facility. The server includes a communication unit (acquiring unit) for acquiring the information, and a processor (control unit) for requesting a user of the electrified vehicle to perform power control on EVSE using the electrified vehicle based on the information acquired by the communication unit. Then, when a predetermined condition related to power control is satisfied by the user, the processor gives a privilege related to the accommodation facility to the user.
