Thermal assessment of an airtight battery-storage container
A thermal container analysis assessed heat balance, air-conditioning units and airflow in an airtight stationary battery-storage system.
Engineering question
A new airtight container concept had to remain within a safe temperature range at high ambient temperature using air-conditioning units only.
Boundary conditions
- Thermally demanding ambient condition
- High solar radiation as an additional boundary condition
- Airtight container with air-conditioning units
Results of the assessment
- The calculated cooling capacity was sufficient for the load case assessed.
- Cool air routed behind the storage modules improved the critical temperature distribution.
- Additional flow distributors were assessed as unnecessary for this layout.
Engineering consequence
Component position and targeted rear-side airflow were identified as key design levers.
Context
The results apply to the container layout and thermal load case assessed.
