What is a coolant pump?

> The coolant pump is a critical component in the thermal management of a battery storage system (BESS) according to IEC 62933. It ensures the constant flow of the cooling medium through the battery modules to keep the operating temperature within the specified tolerance limits. Precise control of the pump prevents thermal degradation and secures the lifespan of the cells.

No own register — honestly

For this component, no specific register is assigned; therefore, no example value is 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
  • Increased temperature gradients in the pack as an indicator of pump faults
  • Divergent flow rates to identify obstructions or leaks
  • An increase in the electrical consumption of the pump as an index of mechanical wear
  • Unstable operating temperatures as an early indicator of reduced resistance to cycles
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, shortened lifespan that no one sees immediately. The AI: identifies the deviating sensor and distinguishes cooling from cell problems. It detects the trend before the limit value is reached.

Why it is important

An efficient coolant pump minimises capacity loss through cell ageing and maximises the usable cycles of the BESS. Stable operating temperatures prevent irreversible chemical degradation processes in the cells. This extends the economic lifespan of the system and secures the projected profitability. Continuous operation above optimum (K) → — K above optimum Calculation path: Rule of thumb: every +10 K ~ half of the calendar life
