48V100K Applications

TELECOM BACKUP POWER
High-energy density enables more usable capacity in less space Maintenance-free long calendar and float life lower overall cost of ownership

WEAK-GRID WIRELESS INFRASTRUCTURE
Long cycle life, even with deep DoD cycles, and partial state of charge Fast charging during periods of grid power availability

OFF-GRID WIRELESS BASE STATIONS
• High performance over full depth-of-discharge range optimizes renewable generation integration
• Integrated intelligence allows real-time monitoring of storage systems at remote sites

OUTSIDE PLANT INFRASTRUCTURE
Reliable performance over wide operating temperature range
High-energy density for space-constrained environments

BEHIND-THE-METER ENERGY STORAGE
Flexibility across full range of available power and energy enables many use cases Ideal building block for PV integration, demand charge avoidance, backup power

Light Weight
The 48V100 K components are only one third the weight of comparable lead acid battery configurations, and consume less space

Long Life Cycle
NEC Energy Solution’s 48V100 K Kit enables up to 10X the cycle life and 5X better float/calendar life of comparable lead acid battery solutions, even at elevated temperatures. Cycle life is double that of other lithium-ion solutions.

Fast Charge Acceptance
Designs based on the 48V100 K are capable of charging up to five times faster than competing lead acid batteries, increasing battery system availability for improved backup system reliability. For remote telecom applications with limited grid connectivity, this simplifies renewable generation (such as PV solar) integration and/or reduces reliance on diesel generator support, lowering overall TCO

High Power
The 48V100 K kit enables systems with twice the power of comparable lead acid batteries, and even other lithium-ion solutions. Full energy capacity is supported even at high discharge rates and deep cycling, allowing system power requirements to be met with fewer batteries.

Reliability and Safety
The integrated BMS improves overall system reliability, safety, and longevity through cell balancing, temperature and state-of-charge reporting, and protecting against short-circuit, over-charge, and over-discharge conditions.

Imergy ESP5 energy storage platform
2.5 kW and 5 kW, 10 to 30 kWh
A Flow Battery is an energy storage device where power and energy are independent Power is derived from “Electrochemical Cells” or “Cell Stacks”
Electrolyte held in separate tanks stores the Energy
Pumps circulate electrolyte through the Cell Stacks which converts
electrochemical energy into electricity. And vice versa.
Control system manage the electrolyte circulation
Flow battery technologies are mainly distinguished by electrolyte composition
o Vanadium Redox
o Fe – Cr
o Zn – Br Picture33IDEAL FOR CRITICAL APPLICATIONS
Rapid charging, deep discharge tolerance and high capacity facilitate 24-hour power availability for mission-critical applications such as wireless telecom towers and transportation infrastructures. The ESP is also a perfect complement to renewable technology systems, including solar arrays, wind turbines, and fuel cell generators. The system architecture allows power and capacity to be specified separately, enabling tailoring of the ESP to site-specific requirements.

EASE OF INSTALLATION
Imergy’s ESP System is fully integrated and factory-tested prior to delivery, and no on-site conditioning nor commissioning cycles are required. Site preparation is limited to providing a suitable support surface.

REMOTE MONITORING, ADVANCED MANAGEMENT AND MAINTENANCE
Monitoring and maintenance go hand-in-hand with the ESP System’s built-in performance monitoring and condition-based maintenance system, providing real-time data acquisition through the integrated supervisory control and data acquisition (SCADA) system. It provides isolated digital inputs/outputs and a USB communication port for PC connection. The ICS sends the sensor data and the ESP data to remote servers through GPRS and SMS.

UNLIMITED CHARGE AND DISCHARGE CYCLES
Because the ESP stores energy in liquids and eliminates the solid-state interactions in conventional rechargeable batteries, Imergy’s ESP technology enables unlimited cycles at 100% DOD over its service life. Unlike other technologies, all the energy stored is usable with no recommended reduced operating performance, over the whole temperature range.
