New battery system saves space in UUV
Saft has been awarded a contract by Groupe d’Etudes Sous Marines de l’Atlantique (GESMA) to develop a rechargeable Li-ion battery system that will boost the performance and payload capacity of its Redermor experimental unmanned underwater vehicle (UUV) platform.
The new battery system – based on Saft’s VL45E Li-ion cells – will provide Redermor with up to five hours of autonomous power for its electric thrusters and onboard electronics, but occupy only half the space previously required.
Powered by a 260V battery, Redermor is a fully autonomous free swimming vehicle. It is 6m long, about 1m in diameter and weighs up to 3.2tonne. Eight electric thrusters allow Redermor to travel at up to 10 knots and at depths of 200m.
