Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle storage batteries are utilized to supply power to the grid during non-driving periods, then grid power stability is improved and peak demand is reduced, but system complexity increases due to integration requirements
Solution Approach 1:
The storage battery system is designed to perform multiple functions: serving as a power source for the vehicle during driving, and as a power supply to the grid during non-driving periods. This multi-functionality allows the same battery infrastructure to stabilize grid power without requiring separate dedicated energy storage systems, thereby improving grid reliability while limiting the increase in system complexity.
Solution Approach 2:
The system enables vehicles to serve the grid during non-driving periods when they are not needed for transportation. The battery management unit automatically manages the dual-purpose operation, allowing the storage battery to self-regulate between vehicle power supply and grid power supply modes, reducing the need for complex external control infrastructure.
2Loss of energy
If the control unit manages both vehicle battery operations and grid power distribution, then energy efficiency is improved by reducing peak demand, but operational complexity increases
Solution Approach 1:
The control unit is designed with multi-functionality to manage both vehicle battery operations and grid power distribution. It monitors battery charge levels, determines optimal discharge timing for grid power supply, and coordinates with the power management system to reduce peak demand. This integrated approach improves energy efficiency by utilizing stored energy during high-demand periods while consolidating control functions into a single unit, thereby limiting the increase in operational complexity.
3Productivity
If vehicle batteries supply power to the grid during non-use periods, then power shortages are mitigated and energy distribution is optimized, but infrastructure requirements increase
Solution Approach 1:
The system merges the vehicle's existing battery infrastructure with the grid power distribution system. By integrating the storage battery's power supply capability with the grid during non-driving periods, the system optimizes energy distribution without requiring separate dedicated infrastructure. The battery management unit and power supply unit work together to combine vehicle energy storage with grid distribution, improving productivity while utilizing already-deployed vehicle battery systems rather than building new infrastructure.

AI summary
A power management apparatus is provided with a power supply control unit for controlling the supply of power from a system to a facility load. In a state in which a storage cell mounted in a vehicle is electrically connected to the system, the power supply control unit acquires information relating to the storage cell status, and on the basis of the information and vehicle operation input, supplies power stored in the storage cell to at least one of the system and the load.
