Solution Overview

Problem

Conventional energy storage power stations require additional supplementary cabinets to maintain stability, limiting the use of industrial and commercial energy storage cabinets, which cannot supplement electric power to the energy storage power station.

Innovation Solution

An energy storage device with a supplementary unit integrated into an energy storage cabinet, allowing the cabinet to operate separately for energy storage and in conjunction with the supplementary unit to supplement electric power to the energy storage power station, eliminating the need for a separate supplementary cabinet.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate supplementary cabinet is added to the energy storage power station, then the power station can maintain stability and supplement electric power, but the device complexity increases and industrial and commercial energy storage cabinets cannot be used as supplementary cabinets

Engineering Contradiction:
Improvepower station stabilityVSAvoidcabinet system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The energy storage cabinet is designed with dual functionality: it can operate independently as a standalone energy storage cabinet or be combined with the supplementary unit to function as a supplementary cabinet for the power station. This multi-functionality eliminates the need for separate cabinet types and reduces overall system complexity while maintaining power station stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The supplementary unit is integrated with the energy storage cabinet to form a combined system. The control unit of the energy storage cabinet can control both the battery cluster inside the cabinet and the supplementary unit, enabling unified management and reducing the need for separate control systems, thereby decreasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If industrial and commercial energy storage cabinets are used separately, then they provide energy storage function, but they cannot supplement electric power to the energy storage power station

Engineering Contradiction:
Improvecabinet usage flexibilityVSAvoidpower supplementation capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The energy storage cabinet is designed with universal functionality that allows it to operate in two modes: independent energy storage mode and power supplementation mode. By integrating the supplementary unit and configuring the control unit to manage both internal battery clusters and external supplementary units, the cabinet can adapt to different operational requirements while maintaining both energy storage and power supplementation capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the supplementary unit is integrated into the energy storage cabinet, then the cabinet can supplement electric power to the power station, but the manufacturing complexity increases

Engineering Contradiction:
Improvedual function capabilityVSAvoidcabinet assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The supplementary unit is designed as a detachable component that can be separately manufactured and then assembled with the energy storage cabinet. This segmentation allows for independent manufacturing of the cabinet and supplementary unit, simplifying production processes while enabling dual functionality when assembled together. The control unit is configured to manage both components, but their separate manufacture reduces overall manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

An energy storage device and an energy storage power station are provided. The energy storage device includes an energy storage cabinet and a supplementary unit. A supplementary mounting position is provided on an outer side of a cabinet body of the energy storage cabinet, and the supplementary unit is arranged outside the cabinet body and at the supplementary mounting position. The energy storage cabinet is operable separately, and the energy storage cabinet is operable in conjunction with the supplementary unit for the energy storage device to supplement electric power to an energy storage power station. In the energy storage device, the energy storage device has the function of energy storage if the energy storage cabinet is operated separately, and the energy storage device is capable of supplementing electric power to the energy storage power station if the energy storage cabinet is operated in conjunction with the supplementary unit, and thus the energy storage device has the function of supplementing electric power to the energy storage power station. Therefore, the energy storage device has the functions of energy storage and supplementing electric power to the energy storage power station, which expands the functions of the energy storage cabinet. It is not required to provide a separate supplementary cabinet for the energy storage power station, which improves the flexibility of use.
