What is an individual cell?

> Monitoring of individual cells in a battery storage system (BESS) is critical for system integrity according to IEC 62619. Each cell acts as the basic unit of capacity, whose individual state determines the overall lifespan of the storage system. Precise recording of cell voltage ensures pack homogeneity and prevents premature degradation.

Bound to the register

cell_v This Wizard is linked to a real register. The value is read as read-only and calculated in-house — nothing leaves the site. The value runs inside the container.

What the AI reads in this component

What the AI reads
  • Cell voltage imbalance as an indicator of internal resistances
  • Deviations in the cell_v register to identify degradation profiles
  • Detection of overcharge or deep discharge states of individual cells to prevent thermal runaway
  • Monitoring of voltage gradients during charging cycles to optimise state of health (SoH)
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 cell monitoring minimises failures due to thermal instability and maximises the number of usable cycles. By preventing cell degradation, capacity remains stable over years. This ensures the projected profitability of the solar plant through reduced maintenance costs. usable capacity (kWh) · SoC (%) · Reserve (%) → — kWh available Calculation: Capacity × (SoC − Reserve) ÷ 100
