EV Battery Emission Tracking for Green Zone Travel Permission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively manage electric vehicles' entry and travel within 'green zones' by solely relying on EV mode, as they do not account for the greenhouse gas emissions associated with the generation of electric power stored in the vehicle's battery, which may not meet stringent emission reduction goals.
Innovation Solution
A server system that assesses the emission intensity of electric power stored in a vehicle's battery and determines permission to enter or travel within a green zone by associating the power amount with its emission intensity, notifying users and administrators accordingly, and managing the display of this information within the vehicle and externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle is permitted to travel within the green zone based solely on EV mode determination, then the ease of operation is improved, but the measurement precision of greenhouse gas emission management deteriorates
Solution Approach 1:
The patent segments the electric power stored in the battery into multiple portions based on emission intensity, distinguishing between clean power (low emission intensity) and conventional power (high emission intensity). This segmentation enables precise tracking of the emission characteristics of each power portion, allowing the system to accurately determine whether the vehicle meets the green zone's emission requirements while maintaining operational simplicity through automated server-based calculation and notification.
2Measurement precision
If the system tracks emission intensity of electric power from charging facilities, then the measurement precision of greenhouse gas emission is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes the complex tasks of tracking emission intensity, calculating the amounts of clean and conventional power, and determining green zone eligibility. Rather than embedding complex measurement and calculation systems in the vehicle itself, the server handles these functions by receiving charging information from facilities and processing it to provide determination results to the vehicle's notification device, thereby reducing on-vehicle device complexity while maintaining high measurement precision.
3Measurement precision
If the server determines permission based on detailed emission intensity analysis, then the measurement precision is improved, but the loss of time in processing increases
Solution Approach 1:
The patent implements preliminary action by having the server perform emission intensity analysis and determination calculations in advance, before the vehicle needs to enter the green zone. The server receives charging information, calculates the amounts of clean and conventional power, and determines green zone eligibility ahead of time, providing the result to the notification device. This advance processing eliminates time-consuming calculations at the moment of entry decision, reducing loss of time while maintaining measurement precision.

AI summary
A green zone exists in which traveling of a vehicle using an amount of electric power that has a greenhouse gas emission intensity greater than a regulatory limit is restricted. A server includes. I/O ports through which the emission intensity of the electric power supplied from an electric vehicle supply equipment is obtained; and a processor that associates the amount of electric power charged from the electric vehicle supply equipment to a battery with the emission intensity obtained through the I/O ports. The processor: determines, based on an amount of electric power having an emission intensity less than the regulatory limit within the amount of electric power stored in the battery, whether a vehicle should be permitted to travel in the green zone; and notifies a user of the vehicle of a determination result.
