What is a rack-module?

> The rack-module is the primary structural and electrical unit within a battery energy storage system (BESS), in which individual battery cells are grouped into functional groups. It serves as the central interface for the battery management system (BMS) to monitor cell voltages, temperatures, and currents. Precise monitoring of the rack-module is essential according to IEC 62933 / UTE storage guide to maximise cell lifespan and ensure system availability.

No own register — honestly

For this component, no own register is connected; therefore, no example value is provided here. Where the plant measures, the value is read as read-only and calculated internally. It is visible via connected components.

What the AI reads in this component

What the AI reads
  • Cell voltage gradients: Detection of cell imbalances to prevent premature degradation.
  • Temperature profiles: Identification of hot spots in the rack to ensure thermal stability.
  • SOC/SOH balancing: Precise determination of State of Charge and State of Health for capacity planning.
  • Power balancing: Detection of internal resistance increases for proactive module maintenance.
Scenario

Monitored: continuous

The scenario: > Monitored: continuously · every cell, every rack The scenario: a weak cell silently limits capacity, resulting in lower yield per cycle, without an alarm. The AI: tracks outliers over cycles and reports them before they slow down the string. It identifies the trend before the limit is reached.

Why it is important

Precise monitoring of rack-modules minimises downtime and extends cycle life, directly shortening the BESS payback period. By identifying cell degradation at an early stage, targeted maintenance intervals can be planned. This prevents costly emergency interventions and ensures continuous feed-in power to the grid. usable capacity (kWh) · SoC (%) · Reserve (%) → — kWh available Calculation: Capacity × (SoC − Reserve) ÷ 100
