The U-Charge XP series or lithium batteries is intended for high current, high voltage applications. Developer Valence says its U-Charge Energy Storage and Management Systems are a family of 12V and 18V battery modules and accessories that have twice the run-time and nearly half the weight of similar sized lead-acid batteries. The modules are built with the firm’s lithium iron magnesium phosphate chemistry for a long cycle life and low ownership cost.
Stationary batteries provide electrical power to systems during 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.
Lithium-iron magnesium-phosphate batteries, from Valence Energy Storage Solutions, Austin, Texas, are said to offer large format back-up and UPS capability for commercial and utilities applications including:
- Back-up and UPS applications include back-up servers and data centers, remote base stations and generators, and telecoms.
- Auxiliary power units
- Hybrid generation sets
- Peak shaving
- Renewable energy back-up (solar, off/onshore wind power and tidal)
Lead acid has been the only chemistry of choice until now. With rising costs of lead, maintenance and safety concerns, the company’s lithium iron magnesium phosphate is poised as a strong candidate to replace the lead acid battery with a lighter, lower maintenance, and higher performance.
Battery features are said to include:
- Excellent float characteristics and cycle life
- Safety
- Reduced size and weight vs lead acid
- Almost zero maintenance
- Remote battery status monitoring and alarms
- No heavy metals (easier disposal at end of battery life)
Valence is receiving inquiries from multinational electric and power distribution companies looking improve capability and develop better green credentials.
