What is the cooling circuit (Liquid Cooling)?

> The cooling circuit in a battery storage system (BESS) is the primary thermal management system for stabilising cell temperature. Precise temperature control according to IEC 62933 is crucial to minimise internal resistance and limit cell degradation. An efficient Liquid Cooling System enables higher power density and extends the lifespan of the entire storage system.

No own register — honestly

For this component, no own register is connected; therefore, no example value is intentionally provided here. Where the system 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 temperature (T_cell) as an indicator of degradation rates
  • Average coolant temperature to monitor heat dissipation performance
  • Differential pressure in the circuit for leak or obstruction detection
  • Pump rotation speed to analyse the energy consumption of the cooling system
Scenario

Monitored: continuous

The scenario: > Monitored: continuously · Interconnected sensors The scenario: one point remains too hot for a long time, the cell there ages faster, its lifespan shortened in a way that no one notices immediately. The AI: identifies the deviating sensor and distinguishes between a cooling issue and a cell problem. It detects the trend before the limit value is reached.

Why it is important

Stable operating temperatures reduce capacity loss and maximise the number of available charge cycles. Optimised cooling prevents thermal runaway and protects cell chemistry from irreversible damage. This leads to a higher state of health (SOH) and thus a direct increase in economic profitability. Continuous operation above optimum (K) → — K above optimum Calculation path: rule of thumb: every +10 K ~ half the calendar life
