Electric Vehicle Power Outlet Management via Dynamic Battery Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power management systems for electric vehicles do not provide a leisure mode that allows users to easily access and utilize power outlets for activities like camping or fishing, as they require complex authentication processes and do not consider the user's location or battery status effectively.
Innovation Solution
An apparatus and method that collect surrounding information to determine if a user is engaging in leisure activities, allowing power supply to outlets when plugged in, while also blocking power if the vehicle's battery level is insufficient to reach a charging station, and includes features like notification systems and smart key authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power is supplied to outlet for leisure activities, then user convenience is improved, but battery drainage increases
Solution Approach 1:
The power management device continuously monitors battery status and provides feedback control by dynamically adjusting power supply to the outlet based on real-time battery level, SOC (state of charge), and drivable distance calculations. When battery level drops below thresholds or drivable distance becomes insufficient, the system automatically blocks power supply to prevent excessive drainage
Solution Approach 2:
The system transitions between different power supply states (enabled, blocked, warning) based on dynamic conditions including battery level, charging status, and drivable distance. The power supply mode is not static but adapts continuously to changing battery conditions and vehicle state
2Reliability
If complex authentication process is required for power supply, then power management control is improved, but user convenience deteriorates
Solution Approach 1:
The power management device automatically determines whether to supply power to the outlet based on pre-set conditions and real-time vehicle state without requiring manual user authentication. The system self-evaluates battery status, charging condition, and drivable distance, then automatically enables or blocks power supply, eliminating the need for complex user authentication processes
3Reliability
If power supply is blocked when drivable distance is insufficient, then battery depletion is prevented, but user access to power outlet is restricted
Solution Approach 1:
The system proactively blocks power supply to the outlet when predicted drivable distance falls below a threshold, preventing the harmful effect of battery depletion before it occurs. By calculating drivable distance in advance and comparing it against required thresholds, the system takes preventive action to ensure the vehicle maintains sufficient charge to reach a charging station

AI summary
An apparatus for managing power of an electric vehicle and a method thereof are provided. The apparatus determines whether a user participates in a leisure activity based on surrounding information of the electric vehicle, and supplies power when a plug is connected to an outlet provided in the electric vehicle while entering a leisure mode to allow the user to use the outlet during leisure activities. The apparatus includes an information collector that collects surrounding information of the electronic vehicle, and a controller that determines whether a user is performing a leisure activity based on the surrounding information of the electric vehicle collected by the information collector and adjusts power supply based on whether an outlet provided in the electric vehicle is plugged in in a leisure mode indicating that the user is performing a leisure activity.
