Battery Cluster Ring Layout for Shorter Series Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage systems have high costs due to long cables connecting battery modules in series, which increase the overall cost of the system.
Innovation Solution
The battery cluster rearranges modules in even rows with a ring connection configuration, reducing the length of connecting cables by connecting each module in series with an adjacent one, forming a ring connection that brings the positive and negative electrodes closer to the switch box, thereby shortening the cable length and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If battery modules are connected in series from bottom to top and then to the switch box, then the connection is simple, but the cable length becomes long and cost increases
Solution Approach 1:
The patent transitions from a one-dimensional vertical connection (bottom to top) to a two-dimensional arrangement where battery modules are connected in series along adjacent rows. This spatial reconfiguration allows the connection path to extend horizontally across multiple modules before reaching the switch box, effectively distributing the cable length across a broader area rather than concentrating it in a single vertical run.
Solution Approach 2:
The patent divides the battery cluster into multiple adjacent rows of battery modules. Instead of connecting all modules in a single vertical sequence, the connection is segmented across multiple rows, with each row connected in series to the next. This segmentation allows the positive and negative electrodes to be positioned closer to the switch box, reducing the overall cable length required.
2Length of stationary object
If battery modules are arranged to reduce cable length, then cable cost decreases, but the arrangement complexity increases
Solution Approach 1:
The patent changes the arrangement parameters of battery modules from a simple vertical stack to a multi-row configuration where modules are arranged in even rows. This parameter change allows the positive and negative electrodes to be positioned closer to the switch box, reducing cable length while maintaining a systematic and manageable arrangement pattern.
3Ease of manufacture
If long cables are used to connect battery modules in series, then the system is easy to assemble, but the total system cost increases
Solution Approach 1:
The patent reconfigures the battery module arrangement from a vertical stack to a multi-row layout, changing the dimensional distribution of connections. This allows the cable material to be distributed more efficiently across the battery cluster, reducing the total quantity of cable material needed while maintaining straightforward series connections that are easy to assemble.

AI summary
A battery cluster and an energy storage system are provided. The battery cluster includes multiple battery modules, all of the multiple battery modules are arranged in even rows, and each battery module is connected in series with an adjacent battery module one by one, to form a ring connection. Such that the length of a cable connecting a positive electrode and a negative electrode of a battery cluster to a switch box is less than a preset value. In the present disclosure, each battery module in the battery cluster is connected in series with an adjacent battery module one by one, such that a ring connection is formed, thereby reducing the cost of connecting cables and the total cost of the energy storage system.
