Liquid cooling
Liquid cooling in the Speichercampus context: strong under high continuous power and energy density. Technically, the term is usually described as heat removal via a cooling medium.
What does liquid cooling mean?
With liquid cooling, a coolant circulates through cooling plates directly at the battery modules. Heat is collected where it arises — keeping the temperature difference between cells typically below 3 °C and the ageing of all strings even.
It becomes necessary at high continuous power, high C-rates, dense packing (containers!) and hot sites. The counterpart: pumps, a cooling circuit and maintenance needs, plus higher auxiliary consumption.
What matters in practice
- practically standard for containers and high cycle counts
- include coolant maintenance and antifreeze in the service contract
- account for the cooling’s own consumption in the RTE balance
- siting: chiller units need exhaust routing and clearance
Practical example
An industrial business cycles twice daily at 0.8C for peak shaving in two-shift operation. The liquid-cooled OmniCube L233 keeps the cells evenly in their window — air-cooled, derating would have become the problem at this continuous load.
The Speichercampus perspective
Speichercampus uses liquid cooling deliberately where continuous load or form factor demands it — from the L233 and the E261LP to all container classes.
