Power Cap™ - The Long-Life Battery Alternative
Zero Emissions Developments is proud to announce it’s Behind The Meter® distributed energy solution for residential applications that incorporates the long life Power Cap™ System. The system has been designed to supply the daily energy needs of homes, day and night whether grid connected or grid independent from an on-site renewable solar PV system that is coupled with our long-life Graphene Supercapacitor system.
The Power Cap™ system that is superior to battery technology and up to 100 times the life
ZED’s Behind-The-Meter® Power Cap™ Solution Features and Benefits
ZED’s Power Cap™ system can deliver many benefits over conventional electro-chemical batteries, such as:
Expected life is over 1,000,000 cycles which equates to approximately 25 year life in normal applications;
Deep cycle discharge, long duration discharge as well as fast charge and short discharge;
The Fast Charging capabilities eliminates the Need for Large Battery Banks;
The Supercapacitor bank can be charged in a few minutes 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;
Graphene ultra-thin layers increases Energy Density over standard supercapacitors;
The proprietary algorithm-based balancing, charging and control circuit used, 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 energy storage system can be deployed at industry that contains high inductive loads.
Levellised Cost of Energy per cycle is less than one, one hundredth the cost of battery technology ($0.01 versus $0.10/kWh/Cycle);
High Efficiency, with a Depth-of-Discharge (DOD) of 99% and round-trip efficiency of 99.1%, the ZED Behind-The-Meter® system delivered and rated capacity are almost the same, allowing for a significant reduction in the number of Supercapacitors required when compared to systems utilizing chemical batteries, thereby lowering capital investment;
Cycle Life more than 100 times that of conventional battery storage, leading to Lower Cost of Ownership;
The cycle life of the energy storage system is 1 million cycles at 99% DOD with negligible capacity fade and impact of charge / discharge rates. Combined with very low maintenance requirements, ZED 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 electro-chemical batteries, the Power Cap™ can be deployed in extremely harsh environments without cooling or heating, resulting in less oversight and maintenance;
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;
These units can be paralleled to increase the total storage capacity; and
The unit is 100% recyclable at the end of its life.
