Saft’s rechargeable Li-ion battery systems represent the most promising approach for both light weight and heavy weight (LWT and HWT) training and exercise torpedoes. Although currently slightly more expensive than secondary Ag-Zn batteries, the reusability of Li-ion batteries ensures low life-cycle costs, bringing cost-effectiveness to sea trials.

 

 

Features & Benefits

 

Saft provides a custom-made service to develop the ideal Li-ion battery system to suit a customer’s specific performance requirements for each torpedo. The battery is made up of a number of Li-ion cell modules connected in parallel to provide the required capacity; these are then connected in series to provide the required voltage. The Li-ion battery is managed by an electronic control system adapted by Saft to suit the specific torpedo application.
