Sirius Super Capacitor 3.55kwh 48vdc

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, along with all the inherent advantages supercapacitors have over conventional chemical batteries.

Currently only available in the 48v version with 12v and 24v arriving soon.

Fast Charging

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 Stabilizing 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.

High Efficiency

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 batteries 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.

Cycle Life

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.

Temperature Tolerance

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 to 14 days.

Expansion

These units can be paralleled to increase the total storage capacity
