Applications and Key Benefits
48V sodium nickel chloride battery,
specifically designed for telecom application
Suitable for:
- Hybrid or off-grid installation
- Installation in remote location
- Use with renewable energy (Wind / Solar)
- Frequent power outages
- Extreme temperature conditions
- Installation with very compact
space availability
Constant performance at -20° to +60°C / -4°F to 140°F
No cooling required
>2000 cycles at 80% DoD
100% maintenance free in operation
Allows remote monitoring
Specific energy 70% lighter and
30% smaller than conventional batteries
Very low total cost of ownership (TCO)
compared to other battery technologies
Very long shelf life without maintenance
Capacity to store energy indefinitely
when not connected
No outgassing and zero ambient emission
Sodium Nickel Chloride Technology
- Use of sodium and nickel as active materials, with solid
ceramic electrolyte
- Active materials contained in sealed steel sheet cells
- “hot battery” - internal operating temperature around
300°C / 572°F
- Made with 2,58 Volt cells with 140 Wh/kg /
310 Wh/Ib and 280 Wh/liter specific density
- Proven technology for energy storage and clean powering
of electric vehicles
- Zero ambient emission:
can be installed in a sealed environment
- Battery outside temperature only few degrees above
the ambient temperature
- Efficient material usage and 100% recyclable:
stainless steel, nickel, iron, salt, ceramic
- Free of toxic materials: no lead or cadmium
- RoHs compliant
- Technical Features
- Steel cell case and double stainless steel battery case
- Integrated battery monitoring system (BMS) for monitoring,
diagnostics and data logging
- User interface on front panel
- Ready for remote diagnostics and monitoring
- Compatible with any DC power supply and standard
telecom rectifiers
- Scalable with parallel operation
- No memory effect
- Typical failure mode (internal short) does not develop
violent energy release - batteries remain in operation with
slight loss of performance
- BMS diagnostics alert on anomalies and disconnect the
battery in case of serious failure
- Supplementary protection with an independent circuitry in
the event of BMS failure
- Integrated low voltage disconnect (LVD)
