Cockeysville, Maryland—Saft says it now manufactures the highest power lithium-ion (Li-ion) cells in the world. Their VLV series claims a specific power double that of high power cells typically available for defense applications and hybrid electric military vehicles.
"Our VLV cells are currently in use on military fighter aircraft providing emergency back-up power to operate flight controls and to start the APU," said Dr. Kamen Nechev, manager of Advanced Development, Saft Space and Defense Division. "The VL6A is an exciting addition to our portfolio of very-high-power cells and will satisfy the power demands of many emerging technologies."
The VLV includes the VL4V, VL8V, and VL12V (see www.saftbatteries.com). The new VL6A, a cell designed for civil applications that require high peak power, is suited to windmill blade pitch control.
The portfolio includes 6, 8 and 12 amp-hour cells with a maximum charge voltage of 4.1 V and an average voltage of 3.6 V. Specific power exceeds 9 kW/kg for two-second long pulses and 12 kW/kg for 100 millisecond long pulses. The cells are capable of a continuous discharge of 6 kW/kg. They are used in battery products ranging from 28 volts to as high as 600 volts.
Saft developed the cells complete with electrical hardware and software monitoring capabilities to provide a completely safe power solution for its customers. Besides their use in providing emergency power, they can be applied to supplemental acceleration and breaking systems in military hybrid electric vehicles and intermediate energy storage in directed energy systems.
