How much energy does a liquid cooled container hold?
The latest generation product has an energy density of more than 440 Wh/l, a roundtrip efficinecy of 96%, and a cycle lifetime of nearly 16,000 charge-discharge cycles. The liquid-cooled system has a voltage range from 1500 V – 2000 V and is configurable for storage durations of two to eight hours. The container weighs around 55 tons.
How much energy does a battery use?
Depth of discharge (DoD): The portion of a battery’s total capacity you actually use. With lead-acid technologies, an effective DoD is typically limited to 50%, while lithium-iron phosphate (LiFePO₄) batteries can safely use up to 80–90%. Usable energy: Your real usable energy is battery capacity × voltage × DoD.
