Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wireless communication schemes are implemented for charging and discharging operations, then information exchange capability is improved, but communication interface standardization is worsened
Solution Approach 1:
The patent segments the communication interface into two distinct parts: a first communication interface for charging reservation information and a second communication interface for charging performance state information. This segmentation allows each interface to be optimized independently, improving information exchange capability while managing the complexity of standardization through modular design.
2Productivity
If real-time information exchange is implemented during charging and discharging, then operational efficiency is improved, but system complexity is worsened
Solution Approach 1:
The communication system is divided into separate interfaces for different functions (reservation vs. performance monitoring), allowing real-time information exchange to be implemented selectively in critical paths without requiring complete system redesign, thus improving operational efficiency while controlling complexity growth.
Solution Approach 2:
Charging reservation information is exchanged before the actual charging process begins, allowing the system to prepare and coordinate in advance. This preliminary action reduces the complexity of real-time coordination during charging by pre-establishing communication channels and protocols.

AI summary
An apparatus for charging a battery of an electric air vehicle includes a transceiver to perform wireless communication with an access point connected to supply equipment, an on-board charger connected to the transceiver, and a high-voltage battery charged based on control by the on-board charger. The on-board charger exchanges information, associated with charging reservation, with the supply equipment via the transceiver and the access point based on a first wireless communication scheme and exchanges information, associated with a charging performance state, with the supply equipment based on a second wireless communication scheme.
