EV Charging Notification Control for Destination-Based Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle devices often notify users to charge or discharge their electrified vehicles unnecessarily, leading to user annoyance.
Innovation Solution
A management server that executes notifications only when specific conditions are met, including the vehicle being at a predetermined charging or discharging location and the request being during a relevant time period, with adjustable notification levels based on the vehicle's state and estimated usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the in-vehicle device executes user notification whenever the vehicle is not connected to charging equipment, then the user is notified about charging needs, but the user experiences annoyance due to unnecessary notifications
Solution Approach 1:
The patent changes the notification parameters by introducing multiple conditions (destination type, presence period, charge/discharge request timing, battery state) that must be satisfied simultaneously. This transforms a simple notification system into a multi-parameter decision system that accurately determines when notifications are truly necessary, thereby improving notification accuracy while eliminating unnecessary notifications that cause user annoyance.
2Object-affected harmful factors
If the management server executes notifications based on multiple conditions, then user annoyance is reduced, but the system complexity increases
Solution Approach 1:
The patent segments the notification decision process into distinct conditional checks: (1) destination type verification, (2) presence period determination, (3) charge/discharge request timing verification, (4) battery state assessment. Each segment handles a specific aspect of the decision-making process, making the overall complex system manageable through modular condition evaluation rather than a monolithic decision structure.
3Reliability
If notifications are executed only when specific conditions are met, then notification appropriateness is improved, but the notification frequency decreases
Solution Approach 1:
The patent applies partial action by executing notifications only for the specific subset of cases where all conditions are satisfied (destination is charging location, vehicle present during request period, battery needs charging/discharge). This partial notification approach prioritizes quality and appropriateness over quantity, ensuring that each notification sent is highly relevant and actionable, even if the total number of notifications decreases.

AI summary
A CEMS server includes a control device that executes a notification process of notifying a user of an electrified vehicle of promotion information for promoting charge or discharge, and a storage device that stores a program executable by the control device. The control device executes the notification process in a case where a first condition and a second condition are satisfied. The control device does not execute the notification process in a case where the first condition or the second condition is not satisfied. The first condition is a condition that a destination of the electrified vehicle is a predetermined place at which the charge or discharge of the electrified vehicle is possible. The second condition is a condition that a request for the charge or discharge is estimated in a period in which the electrified vehicle is present at the predetermined place.
