Batteries provide peak power

A Saft Lithium Battery Division product story
Edited by the Engineeringtalk editorial team Sep 10, 2007

The VL6A high-power cell is designed for civil applications that require peak power, for example in windmill blade pitch control.

Saft's VLV range of lithium ion (Li-ion) cells provide a specific power double that of typical high-power cells that are available for defence applications and hybrid electric military vehicles.

The VL6A is a high-power cell designed for civil applications that require peak power, such as windmill blade pitch control.

"Our VLV cells are already being manufactured and 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.

Saft's portfolio includes 6, 8 and 12Ah cells with a max charge voltage of 4.1V and an average voltage of 3.6 V.

Specific power exceeds 9kW/kg for two-second pulses and 12kW/kg for 100ms pulses.

The cells are capable of continuous discharge of 6kW/kg.

The very high power cells are used in battery products ranging from 28V to as high as 600V.

Saft developed the cells complete with electrical hardware and software monitoring capabilities to provide a completely safe power solution for its customers.

The cells can be used for applications including emergency power for military fighter aircraft, supplemental acceleration and braking in military hybrid electric vehicles, as well as intermediate energy storage in directed energy systems.
