24 Hour Test of a Fuel Cell System for an Autonomous Underwater Vehicle
Gilljam, Martin; Weydahl, Helge; Lian, Torleif; Johannessen, Tom Cato; Holm, Sven Ivar; Hasvold, Jon Øistein (2016)The Norwegian Defence Research Establishment (FFI) has a long experience with power sources for autonomous underwater vehicles (AUVs). FFI has designed and built a power supply system based on a water-cooled and air-supplied ... -
Comparison of thermal runaway initiation methods for a cylindrical Li-ion cell
Weydahl, Helge; Valset, Kjetil; Gilljam, Martin; Lian, Torleif; Gandrud, Knut Bjarne (2021-08-30)Li-ion batteries have become an important part of our daily life in applications as different as cell phones and electric ferries. High energy density is one of the factors for the successful market penetration of this ... -
Fuel cell systems for long-endurance autonomous underwater vehicles – challenges and benefits
Weydahl, Helge; Gilljam, Martin; Lian, Torleif; Johannessen, Tom Cato; Holm, Sven Ivar; Hasvold, Jon Øistein (2019) -
(Invited) Changes in Thermal Stability of Cyclic Aged Commercial Lithium-Ion Cells
Lian, Torleif; Vie, Preben Joakim Svela; Gilljam, Martin; Forseth, Sissel (2019)Thermal stability is one of several factors affecting the safety properties of lithium-ion cells. The thermal stability for uncycled cells is well-documented, but the effect of cyclic ageing on thermal stability is far ... -
Safety aspects of large lithium batteries
Hasvold, Øistein; Forseth, Sissel; Johannessen, Tom C.; Lian, Torleif (2007)A battery containing 294 cells in the form of 7 modules of 42 DD lithium / sulfuryl chloride cells in a 7S6P configuration exploded during in-line inspection pigging of a 30” gas pipeline in April 1999. The gas pressure ...
