SDV utilises lithium-ion battery system from Saft
Saft Space and Defence Batteries
Lithium-ion battery system
Saft has delivered a lithium-ion battery system that offers an improvement in performance and reliability for an electrically propelled Swimmer Delivery Vehicle operated by the French Special Forces.
The Special Forces use the Swimmer Delivery Vehicle (SDV) - a small, piloted submersible craft - to transfer from an offshore point, such as a submarine, to a position close to the coast, at which point the pilots exit the vehicle and swim to land.
The replacement of the existing on-board battery system with Saft's Li-ion technology has enabled an increase in the SDV's performance in terms of maximum speed, range and autonomy, as well as reducing maintenance requirements and offering a longer service life.
For this SDV, Saft has delivered a complete package comprising the Li-ion battery and charger.
The 200V, 20kWh battery system is based on Saft's maintenance-free VL45E cylindrical cells designed specifically for regularly cycling charge/discharge applications that require a battery with a significantly reduced weight and volume.
