Solution Overview
Problem
The existing battery system requires complex and labor-intensive wiring operations for connecting battery management units (BCUs) and cell monitoring units (CMUs), which can lead to errors and increased operator burden during installation and replacement of battery cells.
Innovation Solution
A battery system configuration that includes battery side control units, communication units, and controller side communication units within a battery accommodation casing, allowing for the generation and transmission of synthesized information signals that enable control of battery cells with minimal operator intervention by specifying the installation position of communication units and adding address information to the signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring operations are performed to connect BCU and CMU inside battery modules, then electrical connection between control units is achieved, but operator burden increases and complexity of installation process worsens
Solution Approach 1:
The patent replaces the mechanical wiring operation with a wireless communication system. Controller side communication units and battery side communication units establish wireless connections to transmit and receive signals, eliminating the need for manual wiring operations while maintaining reliable electrical connection functionality.
Solution Approach 2:
The patent introduces communication units as intermediary devices between the controller and battery modules. These communication units handle signal transmission wirelessly, serving as mediators that eliminate direct wiring requirements while ensuring reliable communication between control units and battery cells.
2Reliability
If manual wiring operations are performed, then electrical connections are established, but risk of erroneous wiring increases
Solution Approach 1:
The patent replaces manual wiring operations with wireless communication between controller side communication units and battery side communication units. This substitution eliminates human error in wiring connections while maintaining the necessary communication functionality, thereby improving wiring accuracy without significantly increasing system complexity.
3Reliability
If complex wiring operations are required, then control functionality is achieved, but time for installation and replacement increases
Solution Approach 1:
The patent replaces time-consuming manual wiring operations with wireless communication signals transmitted between communication units. This allows control functionality to be achieved instantly upon installation without the need for complex wiring operations, significantly reducing installation and replacement time while maintaining full control functionality.
4Ease of operation
If wiring operations are simplified, then operator burden decreases, but ability to track individual battery cell positions deteriorates
Solution Approach 1:
The patent replaces manual wiring with wireless communication that incorporates address information in transmitted signals. Each battery side communication unit has a unique address that identifies its position, allowing the controller to track individual cell positions automatically without requiring complex wiring operations, thus reducing operator burden while preserving position information.
