Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home energy management systems (HEMS) do not effectively control the charging and discharging of electric vehicle storage batteries according to user life activities, lacking a technology that aligns these operations with the user's lifestyle.
Innovation Solution
An energy management controller that includes a charge/discharge controller and an operation right granter, which determines and switches between multiple operation modes (manual, plan, and calendar) based on predetermined transition conditions to optimize battery charging and discharging according to user activities, using a power conditioning system to manage the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation modes are introduced to control charging and discharging according to user life activities, then the appropriateness and efficiency of battery management improves, but the device complexity increases
Solution Approach 1:
The control system is segmented into multiple operation modes (manual mode, plan mode, and calendar mode), each handling specific control scenarios. This segmentation allows the system to adapt to different user needs and life activities without creating a monolithic complex control structure. Each mode can be independently managed and switched based on predetermined transition conditions.
Solution Approach 2:
The operation right granter dynamically switches between different operation modes based on predetermined transition conditions related to user life activities. This dynamic adaptability allows the system to respond flexibly to changing user needs while maintaining a relatively simple underlying control structure, resolving the contradiction between adaptability and complexity.
2Ease of operation
If automatic switching between operation modes is implemented based on transition conditions, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The operation right granter automatically monitors transition conditions and switches between operation modes without requiring manual user intervention. The system serves itself by autonomously determining when to switch modes based on predetermined conditions related to user life activities, thereby improving ease of operation while keeping the control logic encapsulated and manageable.
Solution Approach 2:
The system continuously monitors transition conditions and uses this feedback to automatically switch between operation modes. This feedback mechanism enables the system to adapt to changing user needs automatically, improving ease of operation while maintaining controlled complexity through structured feedback loops rather than unmanageable complexity.
3Productivity
If operation modes are switched based on user life activities, then the productivity of energy management improves, but the difficulty of detecting and measuring user activities increases
Solution Approach 1:
The system establishes predetermined transition conditions that define when switching between operation modes should occur based on user life activities. By pre-defining these conditions, the system avoids the need for complex real-time analysis of user behaviors, thereby improving energy management productivity while keeping the detection and measurement requirements manageable through structured, pre-planned criteria.

AI summary
An energy management system includes an energy management controller and a power conditioning system that charges and discharges a storage battery installed in an electric vehicle. The energy management controller includes: a charge/discharge controller that is configured to, in accordance with an operation mode having an operation right among a plurality of operation modes, control charging and discharging of the storage battery through the power conditioning system; and an operation right granter that is configured to determine an operation mode to which the operation right is to be granted next based on a predetermined transition condition, and to grant the operation right to the operation mode determined thereby.
