Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods lack an efficient operation method for using vehicle-mounted batteries as emergency or alternative electric power sources, particularly in managing power supply and demand between vehicles and the grid.
Innovation Solution
A management apparatus and method that acquires registration and use application information to control the supply of electric power from vehicle-mounted batteries to the grid, identifying non-use time periods and adjusting power amounts based on vehicle schedules and history to ensure efficient energy utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle-mounted batteries are used as emergency or alternative electric power sources for the grid, then grid stability and power supply reliability are improved, but the availability of power for vehicle operation may be reduced
Solution Approach 1:
The patent implements dynamic control of battery power discharge by the management apparatus, which adjusts the power supply to the grid based on real-time vehicle usage status. When the vehicle is not being used, the battery discharges power to stabilize the grid; when the vehicle is needed, the discharge is stopped or reduced to ensure sufficient power for operation. This dynamic adjustment resolves the contradiction between grid support and vehicle power availability.
Solution Approach 2:
The management apparatus monitors vehicle usage patterns and power levels, using this feedback to intelligently control when and how much power is discharged to the grid. The system learns from usage history and schedules power discharge during periods when the vehicle is least likely to be needed, thereby maintaining grid stability while preserving adequate power for vehicle operation when required.
2Productivity
If power is supplied from vehicle batteries to the grid during all available time, then maximum power contribution to the grid is achieved, but the battery may not have sufficient charge for subsequent vehicle use
Solution Approach 1:
The management apparatus performs preliminary analysis of vehicle usage schedules and power requirements before controlling power discharge. It identifies optimal time windows for grid power contribution that do not compromise future vehicle operation. By planning ahead and considering upcoming vehicle needs, the system maximizes power contribution during safe time periods while ensuring sufficient charge remains for subsequent vehicle use.
3Productivity
If the management system monitors and controls power discharge based on vehicle usage schedules, then efficient battery utilization is improved, but system complexity increases
Solution Approach 1:
The management apparatus automatically monitors vehicle usage patterns, analyzes power requirements, and controls battery discharge without requiring complex manual intervention or highly sophisticated external systems. The system serves itself by making intelligent decisions based on monitored data, achieving efficient battery utilization through automated scheduling and control while keeping the overall system complexity manageable.

AI summary
A management apparatus that controls charging and discharging between an electric power system and a secondary battery which is mounted on a vehicle and which stores electric power used for traveling of the vehicle includes: an acquisition part that acquires at least one of registration information indicating a use acceptance of the electric power and information indicating a use application of the electric power; and a management part that controls a supply of the electric power from the secondary battery to the electric power system in accordance with the presence or absence of the registration information or the use application of the electric power.
