Electric Power Information Output Device for EV Travel Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for electric vehicles do not provide drivers with sufficient information to plan their travel schedule with time allowance, as they fail to determine if the vehicle can reach the destination based on the remaining battery power, leading to uncertainty and potential delays.
Innovation Solution
An electric power amount information output device that acquires departure and destination information, calculates the required total electric power, and outputs insufficiency information if the remaining battery power is insufficient, also providing details on nearby charging stations and their availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system only provides information about nearby charging stations when battery power falls below a predetermined level, then the device complexity is reduced, but the reliability of travel planning is insufficient because drivers cannot determine if they can reach the destination
Solution Approach 1:
The system performs preliminary calculations of required total electric power amount based on departure and destination points before the driver makes travel decisions. By calculating the power needed for the entire journey in advance and comparing it with remaining battery power, the system provides reliable travel planning information proactively, allowing drivers to plan their travel schedules with sufficient time allowance before embarking on the trip.
Solution Approach 2:
The control section acts as an intermediary that integrates multiple information sources (remaining electric power amount, departure point, destination point) and processes them through logical comparison. It mediates between the raw data and the driver by outputting clear insufficiency information when remaining power is less than required power, translating complex calculations into actionable travel planning guidance.
2Loss of information
If the system calculates required total electric power amount based on departure and destination points, then the information completeness for travel planning is improved, but the loss of time for calculation and data processing increases
Solution Approach 1:
The system calculates the required total electric power amount in advance based on the departure and destination points before the driver needs to make travel decisions. This preliminary calculation ensures that complete travel planning information is ready when needed, eliminating the need for time-consuming calculations during the decision-making process.
3Measurement precision
If the system provides detailed insufficiency information about battery power, then the measurement precision of power status is improved, but the loss of time for processing and communicating detailed information increases
Solution Approach 1:
The system extracts only the essential comparison result from the detailed power amount calculations - specifically, whether the remaining electric power amount is less than the required total electric power amount. By outputting only this critical insufficiency information rather than all calculated details, the system maintains high measurement precision while minimizing the time required to process and communicate the results to the driver.
Data Source
AI summary
In an electric power amount information output device for a vehicle, a control section checks whether a remaining electric power amount of a battery of a motor-driven vehicle at a departure point is less than a total electric power amount required for the vehicle to travel to a destination point. The control section drives an output section to output insufficiency information indicating that the remaining electric power amount of the battery is insufficient, if the remaining electric power amount is less than the required total electric power amount.
