Extended Feature - Multi BMS Control 8 BMS

Order code: SKMCON8BMS01

The MultiBMS Support extension enables advanced-level DC orchestration by integrating multiple independent battery strings into a unified logic layer, effectively removing the hardware requirement for a physical Master BMS. By activating this feature, the controller assumes the role of a central energy storage aggregator, utilising real-time battery string voltages and telemetry to execute a DC string start-up sequence to energise the common DC bus and pre-charge PCS capacitors. This intelligent orchestration staggers the connection of individual strings to the DC bus, effectively suppressing peak inrush and balancing currents and preventing DC link capacitor stress or nuisance tripping. By managing contactor timing and balancing logic during initialisation, the controller ensures a safe, soft-start transition into full operational mode, maintaining system stability across the entire parallel battery bank architecture. 
  • Integration of up to 8 battery strings 
  • Dynamic DC Battery string connection sequence 
  • Active inrush and balance current suppression

    Overview

This extension enables the controller to act as the Master BMS of the energy storage system, allowing multiple battery strings to work together without needing a separate piece of hardware to manage them.   

The Multi BMS Control 8 BMS offers:

  • Advanced DC Orchestration: Enables high-level management and coordination of multiple battery strings.
  • Unified Logic Layer: Integrates independent battery strings into a single energy storage.
  • Eliminates Master BMS Hardware: Removes the necessity of physical requirement for a standalone Master BMS unit.
  • Centralised Aggregation: The controller acts as the central hub for all energy storage data.
  • Real-Time Telemetry: Utilises live voltage and data feeds from each string to make decisions.
  • Automated Start-up Sequence: Executes a precise DC string start-up to energise the common DC bus safely.
  • Integrated Pre-charging: Manages the pre-charge process for PCS (Power Conversion System) capacitors to protect the electronics.
  • Inrush Current Suppression: Minimises current spikes, balancing currents between strings during initialisation.
  • Safe "Soft-Start" Transition: Ensures the entire parallel battery bank is ready before moving into next start up stage and full operational mode.
