Integrated Combiner Cabinet Layout for Energy Storage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems require separate electric control cabinets for current/voltage control, leading to increased space occupation and limited functionality of combiner cabinets.
Innovation Solution
A combiner cabinet design that integrates a cabinet body, door, and electrical component assembly, including positive and negative electrode parts, control parts, and circuit breakers, allowing for compact layout and enhanced functionality by converging external high-voltage boxes directly within the cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate electric control cabinets are used for current/voltage control, then control functionality is achieved, but space occupation increases
Solution Approach 1:
The patent combines the electric control cabinet and combiner cabinet into a single integrated unit. The control part includes current/voltage control components that were previously in separate cabinets, now merged with the combiner cabinet structure. This integration maintains full control functionality while reducing the total number of separate equipment cabinets needed in the energy storage system.
2Adaptability or versatility
If separate electric control cabinets are used for current/voltage control, then control functionality is achieved, but device complexity increases
Solution Approach 1:
The patent merges multiple previously separate equipment cabinets (electric control cabinet and combiner cabinet) into a single integrated cabinet structure. This reduces the overall device complexity by eliminating the need for multiple separate cabinets while preserving all necessary control functions through the integrated control part.
Solution Approach 2:
The integrated cabinet serves multiple functions simultaneously: it acts as both a combiner cabinet for high-voltage box convergence and an electric control cabinet for current/voltage control. The control part within the integrated cabinet provides universal control capabilities that replace the need for separate dedicated control equipment.
3Device complexity
If combiner cabinet has single function, then structure is simple, but functionality is limited
Solution Approach 1:
The patent transforms the combiner cabinet from a single-function device into a multi-functional integrated cabinet. It now performs both combiner functions (converging external high-voltage boxes) and electric control functions (controlling input/output currents and voltages). This is achieved by incorporating the control part with current/voltage control components directly into the combiner cabinet structure.

AI summary
A combiner cabinet and an energy storage system are provided. The combiner cabinet includes a cabinet body (10), a cabinet door (11), and an electrical component assembly (14) mounted inside the cabinet body (10). The electrical component assembly (14) includes a positive electrode part (70), a negative electrode part (80), and a control part (100). The positive electrode part (70) is electrically connected to a positive output terminal of an external high-voltage box and a positive electrode of a battery pack. The negative electrode part (80) is electrically connected to a negative output terminal of the external high-voltage box and a negative electrode of the battery pack. The control part (100) is electrically connected to a communication signal terminal of the external high-voltage box. The control part (100) and the positive electrode part (70) are arranged along a length direction or a width direction of the combiner cabinet.
