Kilowatt Labs’ supercapacitor based energy storage, Sirius, is the first supercapacitor based storage system that delivers deep cycle discharge, long duration discharge as well as fast charge / short discharge, alongwith all the inherent advantages supercapacitors have over conventional chemical batteries.
The Sirius storage system can be deployed from watts to megawatts and has a cycle life of 1 million cycles.
Eliminates the Need For Large Battery Banks
The Sirius battery can be charged in less than 30 seconds without affecting cycle life. This feature delivers significant advantages in a wide range of deployments such as in electric vehicles or utility grade frequency regulation.
An infrastructure of fast-charging stations eliminates the need for large battery banks with extended range. Fast-charging of the Sirius provides utilities with real time response capability to frequency regulation.
Current Control and Stabilising Circuit
Increases Energy Density and Operating Voltage
Sirius’ proprietary algorithm-based balancing, charging and control circuit actively balances and stabilizes the system, delivers deep cycle and long duration discharge and specific energy of 115 Wh/kg. Therefore, in addition to standard fast charge / discharge usage, the Sirius storage system can be deployed at industry voltage, in applications requiring deep cycle discharge including electric vehicles.
Lowers Capital Cost by Reducing the Number Of Batteries
With a Depth-of-Discharge (DOD) of 100% and round-trip efficiency of 99.1%, the Sirius battery’s delivered and rated capacity are almost the same, allowing for a significant reduction in the number of batteries required when compared to systems utilizing chemical batteries, thereby lowering capital investment.
Lower Cost of Ownership
The cycle life of the Sirius storage system is 1 million cycles at 100% DOD with negligible capacity fade and impact of charge / discharge rates. Combined with very low maintenance requirements, Sirius delivers power and energy at an unmatched cost per cycle.
Enables Usage in Most Environments
With a temperature tolerance range that is higher than most chemical batteries, the Sirius battery can be deployed in extremely harsh environments without cooling or heating, resulting in less oversight and maintenance.
Charge Retention Circuit
A charge retention circuit controls a small percentage of embedded Li Ion to supply current to reduce charge leakage and increase self-discharge time 2% per month.
