Sirius Energy Storage
The world’s first supercapacitor-based energy storage system
Testing Sirius model under development

Key Attributes

  • Actively balanced and stable operation at all commercial voltages
  • Flat discharge curve (module discharge rate is determined by the load)
  • 2% per month self-discharge when idle and in sleep mode
  • Cell level energy density of 70-80Wh/kg
  • Supercap cell cycle life and capacity unaffected by high rate of charge or discharge
  • Supercap cell projected calendar life of 45 years and cycle life of 1,000,000 cycles
  • High charge / discharge capability
  • Wide operating temperature range of supercap cells
  • No degradation of capacity and efficiency over cycle life
  • Works with standard inverters/rectifiers/regulators used with Lead Acid or Li Ion batteries
  • Non-toxic, with no risk of thermal runaway
  • Form factor similar to chemical batteries

1 Performance may vary at different temperatures and at different C-rates.

2 Max. rate of charge and discharge is provided for a standard Sirius module. This rate may vary at different temperatures and for different Sirius modules.

3 Rapid charge of storage for EV’s.

4 Rapid charge at 120C is not possible with chemical batteries.

5 On useable capacity basis.

6 Publicly available information. Manufacturer data may vary.

7 Supercap cell level.

Kilowatt Labs’ Sirius Energy Storage is enabling a meaningful transition away from fossil fuels.

*Only available in Australia

1 Alarm activated when a safety event occurs and must be rectified by the user. Deployed so that inverter/rectifier/regulator controls operating parameters of the module.

2 Module has internal safety functionality that automatically shuts down the module in the case of safety event and failure of inverter/rectifier/regulator.
