Solution Overview

Problem

Existing energy storage systems lack efficient and user-friendly methods for setting up communication identifiers for battery management systems, which complicates data communication and management within the system.

Innovation Solution

The implementation of manually adjustable identification setups, such as dip switch or rotary switch units visible on the outside of the battery management systems, allows for setting unique communication identifiers without applying power to the system, enabling efficient communication between battery units and control units via CAN communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If communication identifiers are set through software configuration after power-on, then communication can be established, but the setup process becomes complex and time-consuming

Engineering Contradiction:

Improveease of setting communication identifierVSAvoidtime for setup and inspection

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The communication identifier is pre-configured using physical switches (dip switches or rotary switches) that can be set before the battery management system is powered on. This preliminary mechanical configuration eliminates the need for complex software setup procedures after power-on, directly reducing setup time and improving ease of operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces electronic/software-based identifier configuration with a mechanical switch system. The dip switches or rotary switches provide a physical, tactile interface for setting the communication identifier, substituting the need for software menus, keyboard input, or programming operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If multiple battery management systems are used in the system, then system capacity and control capability are improved, but communication management becomes more complex

Engineering Contradiction:

Improvesystem capacity and control capabilityVSAvoidcommunication management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Each battery management system is assigned a unique communication identifier through its own set of physical switches, allowing independent configuration. This segmentation of identification functions across multiple systems enables scalable expansion without creating centralized management complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each battery management system can independently configure its own communication identifier using its local switches without requiring external programming equipment or complex network configuration procedures. This self-service capability simplifies deployment of multiple systems.

Inventive Principle:

Principle #25Self-service
