During operation, the system generates heat loss depending on the power driven. At the end of life, the losses are highest for the battery, as the internal resistance increases with ageing. The following data are @ End of Life, 25 °C and 1C : (At BoL approx. factor 1.5 lower for the battery)
- Battery cabinet TS HV 30 E (4 modules): 1.0 kW
- Battery cabinet TS HV 50 E (7 modules): 1.7 kW
- Battery cabinet TS HV 80 E (10 modules): 2.5 kW
- STPS X 30: Efficiency approx. 97.3 @ 30 kW → 0.81 kW
- STPS X 50: Efficiency approx. 97.5 % @ 50 kW → 1.25 kW
