Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage power stations face challenges in balancing high-speed and real-time performance in battery information communication due to long communication times in the BCMU→BAMU process, which is critical for battery safety management.
Innovation Solution
Implementing a dual main control module system, comprising an ARM module for first priority information and an FPGA module for second priority information, with separate CAN communication channels to manage and transmit battery data efficiently, reducing communication time and enhancing real-time response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a single communication bus is used for BCMU→BAMU data transmission, then device complexity is reduced, but communication time increases and real-time performance deteriorates
Solution Approach 1:
The patent segments the communication architecture by introducing a dual main control module system (first main control module and second main control module) that communicates with BCMU through separate communication buses. This segmentation divides the single communication channel into multiple independent channels, allowing parallel data transmission and reducing communication time without significantly increasing overall system complexity.
2Speed
If all battery information is transmitted through one communication bus, then ease of operation is maintained, but communication speed decreases and real-time performance is compromised
Solution Approach 1:
The patent segments battery information into different priority levels (first priority and second priority) and transmits them through different communication paths. The first main control module handles first priority information while the second main control module handles second priority information, enabling high-speed transmission of critical data without complicating the overall system operation.
Solution Approach 2:
The patent applies local quality by assigning different communication characteristics to different information types. First priority information (requiring fast response) is transmitted through one communication path, while second priority information is transmitted through another path, optimizing the communication quality for each specific data type.
3Reliability
If a three-level architecture is used for battery management, then reliability is improved through distributed control, but communication time increases due to multiple communication hops
Solution Approach 1:
The patent segments the communication path by introducing a second main control module that directly communicates with BCMU, creating a parallel communication path that bypasses some of the traditional three-level architecture hops. This reduces communication time while maintaining the reliability benefits of distributed control.
Solution Approach 2:
The second main control module acts as an intermediary that directly interfaces with BCMU for second priority information, reducing the number of communication hops required in the traditional three-level architecture and thereby reducing communication time while preserving system reliability.
