Li-ion battery pack, management system features 12,000 charge cycles

The Flex System is comprised of a 24 kWh Li-ion battery cabinet, power electronics and control unit. It is optimized for use in commercial environments and features a long cycle life in excess of 12,000 cycles at 100% depth of discharge. Depending on customer needs and applications, the system can be adjusted to different size and capacity settings up to 1 MWh. The system at Solar Power International, held September 14-17, 2015.

The battery pack and management system is offered for use in an array of solar power systems, and is compatible with standard 480-V, three-phase ac-inverters. It is suited for demand response programs enabling commercial end-use electric customers to reduce their electricity usage in a given time period, or shift that usage to another time period in response to a price signal, a financial incentive, an environmental condition or a reliability signal. The system provides emergency standby non-critical power while ensuring customers are able to minimize and manage their electricity costs through the peak shaving process, and participate in electricity arbitrage systems. It is supplied in a ventilated enclosure, and may be ordered with battery racks providing from 24 kWh to 1,000 kWh. This facilitates their use in stationary storage applications requiring output power from 30 kW to 1,000 kW. More information at www.varta-microbattery.com
