Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple battery units are connected to form a communication network, then data transmission capability is improved, but the line structure becomes complex and failure rate increases
Solution Approach 1:
The patent divides the battery communication network into multiple independent groups, where each group forms a separate communication channel. Battery units are segmented into different groups with designated head units that manage communication within each group. This segmentation reduces the complexity of the overall line structure while maintaining comprehensive data transmission capability across all battery units.
Solution Approach 2:
The patent introduces head units as intermediary devices within each battery group. These head units act as mediators that collect data from member units and transmit it to the control apparatus, or relay control commands to member units. This intermediary layer simplifies the communication architecture by reducing direct connection requirements between all battery units and the control apparatus, thereby reducing line complexity while maintaining communication reliability.
2Reliability
If direct communication connections are established between all battery units and control apparatus, then communication reliability is improved, but system complexity and failure rate increase
Solution Approach 1:
The patent segments the battery units into multiple groups with designated head units. Each head unit manages communication for its group members, creating a hierarchical structure. This segmentation allows the system to maintain reliable communication through organized channels while simplifying operation, as the control apparatus only needs to communicate with head units rather than managing connections to every individual battery unit.
Solution Approach 2:
The head units perform multiple functions: they collect data from member units, transmit data to the control apparatus, relay control commands to members, and manage communication protocols within their groups. This multi-functionality reduces the need for separate dedicated components for each communication task, thereby simplifying system operation while maintaining comprehensive communication coverage and reliability.
3Ease of operation
If a simple communication architecture is used, then ease of operation is improved, but data transmission flexibility is reduced
Solution Approach 1:
The patent implements dynamic communication paths where data can be transmitted through multiple routes depending on the specific communication needs. Head units can selectively forward data from member units to the control apparatus, and the control apparatus can send commands through appropriate head units to target specific groups or individual units. This dynamic routing capability provides data transmission flexibility while maintaining the simplified hierarchical architecture, as the system adapts communication paths based on operational requirements rather than requiring fixed complex connections.

AI summary
A battery system includes: at least two battery groups and a relay apparatus. Each battery group includes a plurality of battery units. The battery units in each battery group are configured to form a first channel that uses the battery units as nodes and sequentially transmits specified data. The at least two battery groups are capable of respectively forming, with a control apparatus, second channels for transmitting the specified data. The relay apparatus is configured to respectively form, with the at least two battery groups, third channels for transmitting the specified data. The relay apparatus is further configured to forward the specified data between the battery groups.
