SMC/Salt Batteries for UPS
SMC/Salt Betteries Technology
Sodium Metal Chloride (SMC) or Salt batteries are the latest generation of secondary batteries developed specifically to the constraints of the heavy industrial applications.
They use metal-based cathode and molten Sodium anode toprovide exceptionally safe and reliable power backup that is enclosed in the industrial-grade steel case and equipped with integrated Battery Monitoring. Stable chemical reactions, zero maintenance and insensitivity to temperature and storageaging make them one of the best choices for Oil & Gas, Power Generation, Transmission and Distribution, Communications, Rail, Offshore and other industrial uses.
How it Works
In the discharged state, the active materials are sodium chlorideand metal powders (mainly nickel). In the charged state, they are converted to sodium and metal chlorides.
The solid state electrolyte, ß-alumina, provides fast transport of sodium ions and ensures the galvanic insulation between anode and cathode.
Cell operating temperature is around 250°C and the thermalinsulation of the battery is such that the surface temperature of the enclosure is just a few degrees above the environment.
The BMS is installed on the external front side of each module and performs the following tasks:
- Charge regulation: sets the optimal charging voltage and current
- Monitoring and diagnostic: performs constant check of correct functioning
- Electrical risks elimination: protects the user from accidental exposure to high voltage
- Battery protection: avoid abuse related risks
- Thermal management: controls the operational temperature
• Remote connection and supervision: provides periodical status of health report
