Vehicle Battery State Estimation for External Device Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not adequately monitor or assess the state of a battery after supplying electric power to another device, which can hinder vehicle travel or device usage.
Innovation Solution
A battery information providing device and system that acquires and estimates the battery charging rate and device battery information to output relevant information about the battery's state, including travel distance, usable time, and suppliable time, using an acquisition part and estimation part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric power is supplied from the vehicle battery to another device, then the device battery can be charged, but the vehicle battery state becomes uncertain and may hinder vehicle travel
Solution Approach 1:
The system performs preliminary estimation of the vehicle battery state before power supply occurs. The estimation unit calculates the post-power-supply battery charging rate based on current battery state and device battery information, allowing users to understand the impact before actual power transfer happens.
Solution Approach 2:
The system provides feedback information about the vehicle battery state during and after power supply to external devices. The output unit displays the estimated battery charging rate, traveling distance, and other parameters, enabling users to monitor battery status and make informed decisions about power supply operations.
2Reliability
If the battery state is monitored after power supply, then travel hindrance can be prevented, but the system complexity increases
Solution Approach 1:
The estimation unit serves multiple functions: it calculates post-power-supply battery charging rate, estimates traveling distance, and provides feedback information. This multi-functionality reduces the need for separate monitoring components, thereby limiting complexity increase while achieving comprehensive battery state monitoring.
3Loss of information
If detailed battery information is provided to users, then users can make informed decisions, but information processing complexity increases
Solution Approach 1:
The system extracts and presents only the most relevant battery information to users, such as post-power-supply charging rate, traveling distance, and power supply time. This selective information extraction avoids overwhelming users with unnecessary data while still providing comprehensive decision-making support.

AI summary
A battery information providing device includes an acquisition part configured to acquire a battery charging rate of a battery, which is mounted on a vehicle and which stores electric power for traveling the vehicle, and device battery information related to a device battery which is included in a device, which is an object to which the electric power is supplied, connected to the vehicle, and an estimation part configured to estimate a state of the battery after the electric power stored in the battery has been supplied to the device battery on the basis of the battery charging rate and the device battery information, and configured to output battery-related information related to the estimated state of the battery to an information output part.
