EV V2L Power Guidance for Charging-Route Range Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles with V2L function face challenges in managing electric power consumption, leading to uncertainty in travelable distance and increased risk of not reaching charging stations due to insufficient battery charge, as users lack guidance on power usage in V2L mode.
Innovation Solution
A method that calculates battery energy requirements and available time for reaching a charging station by integrating a controller with a navigation device, energy consumption model, and real-time traffic information to provide guidance on electric power usage, including scheduling and displaying available time for external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric power is supplied to external equipment in V2L mode, then the utility of the vehicle is improved, but the travelable distance is reduced
Solution Approach 1:
The system continuously monitors battery state of charge and calculates remaining travelable distance in real-time, providing feedback to the user through the display device. This allows users to understand the impact of V2L power consumption on travel range and make informed decisions about power usage.
Solution Approach 2:
The system pre-calculates and displays the relationship between V2L power consumption and travelable distance before the user actually consumes power. By showing the available energy and estimated range in advance, users can plan their power usage to ensure they reach their destination.
2Adaptability or versatility
If electric power is consumed in V2L mode, then the vehicle can support external equipment, but the state of charge of the battery is reduced
Solution Approach 1:
The display device shows real-time information about battery state of charge and power consumption rate, providing feedback to users about how quickly the battery is being depleted. This helps users understand the energy trade-off and adjust their usage accordingly.
Solution Approach 2:
The system pre-calculates and displays the available energy and estimated usage time before power consumption begins. Users can see how much energy is available and plan their external equipment usage to avoid complete battery depletion.
3Loss of information
If the vehicle displays travelable distance based on V2L power consumption, then information is provided to the user, but uncertainty in reaching charging stations increases
Solution Approach 1:
The system provides continuous feedback by updating the travelable distance calculation as power is consumed and as the vehicle approaches the charging station. This dynamic information helps users make real-time decisions about whether to continue using V2L power or conserve energy.

AI summary
The present disclosure provides a method of providing guidance for use of electric power of an electric vehicle capable of limiting use of electric power in a vehicle-to-load (V2L) mode or providing various pieces of information on use of the electric power. The method includes receiving information on a set travel route to an electric vehicle charging station in the V2L mode, calculating battery energy requirements necessary for the vehicle to move from the current location to a charging station along the travel route, calculating available amount of energy in the V2L mode based on the battery energy requirements and the current amount of energy of a battery, calculating an available usage time of an electronic product based on electric power consumption per unit time of the electronic product and the available amount of energy, and displaying the available usage time of the electronic product through an information-providing device.
