In Europe's quest to become a zero-carbon society, and consequently to use more and more electricity, households must become self-sufficient in electricity. The only way to achieve this is to somehow store the surplus electricity generated from renewable sources, in case it is not possible to generate electricity in this way or when the grid is overloaded. For this problem, electricity storage is an excellent solution, as it is suitable for both households and larger commercial installations.
The aim of this thesis is to analyse the thermal conditions of a storage tank and to determine the cooling required for efficient operation.
The thermal analysis of the energy storage system was carried out by measuring the temperature of the inverter and battery modules at full load of the energy storage system during charging and discharging. It was found that the inverter heats up quickly, especially during charging, up to its maximum temperature of 70 °C for safety reasons, which leads to an increase in charging time as the charging current and voltage must be reduced to prevent the inverter from heating up even more. It was also found that the heating of the inverter could be reduced by additional cooling slots on the feeder housing and by an additional fan to remove the hot air from the feeder faster and to cool the inverter further.
