We used our 25 years of experience to design and manufacture a replacement power solution in-house, replacing the NOC’s alkaline and lithium polymer batteries with new lithium thionyl chloride packs.
(PRWEB UK) 14 June 2013
Steatite Batteries has provided a reliable and durable power solution for the National Oceanography Centre’s (NOC) automatic underwater vehicles (AUVs), to help them stay underwater for longer.
Travelling to depths of 6000 metres on ocean research missions, the NOC’s earlier AUVs used alkaline and lithium polymer battery packs. However, with the increasing deployment demands for longer endurance of autosubs and underwater vehicles, the NOC required a fresh approach to power, so it turned to power system experts at Steatite Batteries.
Steatite Batteries worked with the NOC to develop a lithium primary solution that not only increased its AUVs’ endurance, meaning they could maintain limited deployment and recovery times by staying underwater for longer, but also reduced the whole life cost. The lithium primary power solution also offered a number of other benefits over the existing alkaline ones, including increased energy density, weight saving, higher stable head voltage and a better operating temperature range. These advantages will now allow the NOC to collect the maximum amount of data for extended periods at depths of 6000 metres.
Paul Edwards, Business Development Manager at Steatite Batteries, comments: “Lithium batteries are being successfully used in oceanographic applications but don’t have the endurance required for powering long-range underwater missions. We used our 25 years of experience to design and manufacture a replacement power solution in-house, replacing the NOC’s alkaline and lithium polymer batteries with new lithium thionyl chloride packs. These battery packs were tested to meet UN testing criteria part III 38.3 rev 5, clauses T1 – T5 and the finished solution comprises ten battery packs, giving 25.2 Volts DC @ 152Ah, that will be constructed into a frame inside a pressure vessel by the NOC for each AUV.”
