Saft and ABB Develop Li-ion Battery System to Enhance Stability of Power Grids | Green Energy News: "Saft and ABB Develop Li-ion Battery System to Enhance Stability of Power Grids.

The high voltage battery system will provide dynamic energy storage to help respond to disruptions in the grid due to increasing penetration of renewables. The new system combines Saft's 5.2 kV battery with ABB's SVC (Static Var Compensation) Light technology for dynamic voltage control. Potential applications include industries with high short term power demands as well as utility grids fed by a high percentage of variable renewable energy sources, especially wind power.

Li-ion battery technology offers a number of important features in this application, such as excellent cycling capability, long calendar life, high energy density, very short response time, high power capability both in charge and discharge, and maintenance-free design. The battery system comprises eight individual units based on Saft's Intensium Flex modular, rack-mounted Li-ion modules. The units, rated at 646 V and 41 Ah, are connected in series to achieve a nominal voltage of 5.2 kV and the system can deliver 200 kW for an hour and 600 kW for over 15 minutes."
