Energy Storage Module Connectors for Tool-Free Series Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of energy storage facilities becomes complicated due to the need for connection cables between adjacent energy storage apparatuses, requiring connection at both ends, which is exacerbated by the increasing number of apparatuses.
Innovation Solution
Each energy storage apparatus is equipped with first and second power cables connected to positive and negative electrode terminals, respectively, with connectors that allow direct connection between adjacent apparatuses, eliminating the need for separate connection cables and tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection cables are used to electrically connect adjacent energy storage apparatuses, then electrical connection between apparatuses is achieved, but installation work becomes complicated and time-consuming
Solution Approach 1:
The patent merges the connection cable function into the energy storage apparatus itself by providing power cables with connectors that extend from the apparatus housing. This integration eliminates the need for separate connection cables and reduces installation complexity while maintaining reliable electrical connection between adjacent apparatuses.
Solution Approach 2:
The power cables with connectors are pre-installed and extended from the energy storage apparatus during manufacturing. This preliminary action allows the connectors to be ready for direct connection upon installation, eliminating the need for on-site cable installation and connection work between adjacent apparatuses.
2Reliability
If connection cables are connected at both ends to electrode terminals of adjacent apparatuses, then electrical connection is established, but the number of connection points and installation steps increases
Solution Approach 1:
The power cables are pre-installed within the energy storage apparatus during manufacturing, with connectors extending from the housing. This preliminary action reduces installation time by eliminating on-site cable installation and connection steps, while ensuring reliable electrical connection is maintained.
3Quantity of substance
If the number of energy storage apparatuses increases, then energy storage capacity increases, but installation complexity and connection work increase proportionally
Solution Approach 1:
By integrating the connection function into each energy storage apparatus through built-in power cables and connectors, the system enables straightforward connection of multiple apparatuses. This merging approach allows energy storage capacity to scale with the number of apparatuses while keeping installation complexity manageable through standardized, self-contained connection interfaces.

AI summary
An energy storage facility includes a plurality of energy storage apparatuses. Each of the plurality of energy storage apparatuses includes: an energy storage unit an outer case; a positive electrode power cable; and a negative electrode power cable. Each of the positive electrode power cable and the negative electrode power cable is connected to the energy storage unit inside the outer case, and extends from the outer case. The positive electrode power cable includes a positive electrode connector, and the negative electrode power cable includes a negative electrode connector separated from the positive electrode connector. The positive electrode connector of one energy storage apparatus in two energy storage apparatuses adjacent to each other in the plurality of energy storage apparatuses is directly connected to the negative electrode connector of the other energy storage apparatus in the two energy storage apparatuses.
