EV Battery Power Predictor and Notification Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control apparatuses for electric vehicles often fail to ensure sufficient battery power for non-traveling purposes, leading to potential battery exhaustion before reaching the destination, especially when users engage appliances for extended periods.
Innovation Solution
A control apparatus that includes a predictor to calculate the predicted remaining battery power upon arrival and a notification system to inform users of power availability, allowing them to manage appliance usage accordingly, ensuring the vehicle reaches the destination with sufficient power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the generator is controlled based only on the travel plan, then the vehicle can reach the destination, but the battery power may be exhausted before reaching the destination when appliances are used for extended periods
Solution Approach 1:
The control apparatus calculates the predicted amount of remaining power before the vehicle reaches the destination, and provides notifications in advance to the user. This preliminary assessment allows the user to make informed decisions about appliance usage before battery exhaustion occurs, ensuring the vehicle can reliably reach its destination.
Solution Approach 2:
The system provides feedback to the user about the predicted remaining power through notifications. This feedback mechanism informs users about power availability, enabling them to adjust their appliance usage patterns accordingly, thus preventing battery exhaustion while maintaining the ability to reach the destination.
2Ease of operation
If appliances are used for extended periods, then user convenience is improved, but battery power may be exhausted before reaching the destination
Solution Approach 1:
The notification system provides real-time feedback to users about the predicted remaining power, enabling them to make informed decisions about appliance usage. Users can continue to use appliances conveniently as long as the predicted remaining power is sufficient, while being warned in advance when power levels become critical.
Solution Approach 2:
By calculating and notifying users about the predicted remaining power before exhaustion occurs, the system allows users to plan their appliance usage in advance. Users can enjoy appliance convenience during periods when power is sufficient, while being prompted to conserve power before the vehicle reaches the destination.
3Reliability
If the control apparatus provides detailed power predictions and notifications, then battery management is improved, but device complexity increases
Solution Approach 1:
The control apparatus integrates multiple functions into a single system: it calculates predicted remaining power, determines notification timing, and communicates with the user. This multi-functional approach improves battery management reliability without requiring separate dedicated systems for each function, thereby limiting the increase in device complexity.

AI summary
In a control apparatus for an electric vehicle driven by an electric motor being actuated based on electric power supplied from a battery, a predictor is configured to calculate a predicted amount of remaining power of the battery that will remain on arrival of the vehicle at a destination. A notification controller is configured to cause a notifier to provide a notification based on the predicted amount of remaining power of the battery.
