Saft develops batteries for spacecraft

Saft has signed a contract with Eads Space Transportation to provide all the in-flight battery systems for the next 30 Ariane 5 launch vehicles ordered by Arainespace from Eads Space Transportation. This order mostly consists of the new A5 ECA version. Saft is providing a total of 18 individual battery systems to power key elements, including the vehicle equipment bay (VEB) – often called the ‘brains’ of a launcher. Situated on top of the main cryogenic stage its computer systems provide autonomous control for all the systems required to control a flight for its duration such as Vulcain engine ignition, and separation of the boosters and the storable propellant upper stage. Power for the inertial guidance and control systems is provided by two 60V silver oxide-zinc (AgOZn) primary batteries, each comprising 39 x 14 PNS cells capable of supplying 17A for 65 minutes. Also in the VEB, four rechargeable 30V nickel-cadmium (Ni-Cd) batteries, each comprising 25 x VR1.6CE cells, power the pyrotechnic and safety systems.
