Stationary

Stationary batteries are designed to provide electrical power to systems during instances of power outages. They are used in equipment dedicated to stabilizing voltages by eliminating irregularities in systems that generate electrical power. The batteries can hold large loads temporarily as utility power switches from one generation source to another. Hence, applications such as uninterruptible power supplies (UPS), DC power systems, emergency lighting, starter systems, security alarms, and switchgear primarily drive the market for stationary batteries.

Valence lithium iron magnesium phosphate energy storage solutions offer large format back-up and UPS solutions for commercial and utilities applications including:

Back-up / UPS applications including
- back-up servers and data centers
- remote base stations and generators
- telecoms
- switch gear
Auxiliary power units (APU)
Hybrid Gen Sets
Peak shaving
Renewable energy back-up (solar, off/onshore wind power and tidal)
Starter Units

Lead acid has been the only technology of choice up until now. With rising costs of lead, maintenance, safety concerns, size/weight issues and disposal issues, Valence lithium iron magnesium phosphate is poised as a strong candidate to replace the lead acid battery with a lighter, lower maintenance and higher performance solution.

Features of Valence lithium iron magnesium phosphate energy storage solutions include:

Excellent float characteristics and cycle life
Safety
Reduced size and weight vs lead acid
Virtually zero maintenance
Remote battery status monitoring & alarms
No heavy metals (easier disposal at end of battery life)

Valence is receiving inquiries from a range of multinational electric / power distribution companies that are looking improve functionality and develop better green credentials.

Lead Acid batteries along with flywheels, compression, pump hydro etc. have been the only option up to this point. Lithium batteries are now been recognised as a very exciting next generation technology. Lithium iron magnesium phosphate within the Lithium family LiPO4 has emerged very strongly due to its inherit safety, enhanced float characteristics and cycling capabilities. There are many advantages of lithium iron magnesium phosphate over lead acid.

Advantages of sealed lithium iron magnesium phosphate over seal lead acid	Application Benefits
Weight	Less weight to transport VRLA and Flooded LA systems EHS protocols require 2 man lifting It is 10 x more expensive to support weight off shore than onshore
Energy Density	The volumetric reduction over SLA allows for smaller battery enclosures Real Estate for large battery houses in large cities is very expensive
Maintenance Free	Eliminates quarterly checks for SOC and specific gravity measurements, and topping up
Remote Monitoring, SOC, Voltage, Current, etc.	Reduces expensive unscheduled and scheduled maintenance calls, which are particularly expensive for remote locations and offshore wind farms
Flexibility of Orientation	Stacking minimises floor space Terminals mounted on the vertical plane makes install and maintenance easier
SOC and BMS control	Currently all SLA and NiCd systems have limited SOC monitoring, and pack control capabilities
Float	Better float life than other Li Ion chemistries, comparable to current VRLA solutions
EHS & Environmental	No out gassing during charging No dangerous acids Safe handling Lowest environmental effect compared with other chemistries
Scalability	Modular approach allows scalable sizing. 200kWh–2MW
