AI Technical Summary
Technical Problem
The maintenance time and effort required for firmware updates in large-scale ESTATCOM systems with numerous CMSs is significant due to the need for local connection with each CMS.
Method used
A power supporting system with remote firmware loading capabilities, utilizing dedicated communication channels and control devices to update CMSs across multiple strings and racks in parallel, reducing the need for on-site connections and facilitating efficient firmware version verification and update processes.
Benefits of technology
Significantly reduces the time required for firmware updates in large systems by enabling remote and parallel loading, improving maintenance efficiency and reducing the risk of manual errors.

Abstract
The present disclosure relates to a power supporting system (1) comprising an energy storage system (100), ESS, comprising at least one string (S-1, S-M) Each string (S-1, S-M) comprises at least two energy storage racks electrically connected in series. Each energy storage rack comprises at least one energy storage module (ESM-1, ESM-N). Each energy storage module (ESM-1, ESM-N) comprises at least one energy storage cell (C-1, C-2, C-X), and a cell management system (xMS-1, xMS-N) configured to manage said at least one energy storage cell. The power supporting system (1) comprises at least one control device (10, 10-1, 10-M), and at least one primary communication unit (20-1, 20-M), PCU, each PCU (20-1, 20-M) configured to 0 provide a dedicated communication channel between at least one of said at least one control device (10, 10-1, 10-M) and CMSs (xMS-1, xMS-N) of one of said strings (S-1, S-M). Said at least one control device (10, 10-1, 10-M) and said at least one PCU (20-1, 20-M) are arranged remotely relative to said ESS (100). Said at least one control device (10, 10-1, 10-M) is configured to control, by communication via said dedicated communication channels, a remote firmware loading process to update said CMSs (xMS-1, xMS-N) of said at least one string (S-1, S-M). A method of updating CMSs of a power supporting system (1) is also disclosed.
