Publication number: 20220082631Abstract: Systems and methods for accurately determining the state of health (including state of charge and relative age) of a Lithium Sulfur battery, module or cell. The invention uses an operational model of a Lithium Sulfur cell or battery to predict model parameters under a range of conditions related to state of charge and state of health. Operational models include the memory effect due to the unique chemistry of a Lithium Sulfur cell that precludes the user of other methodologies for State of health determination for Lithium Sulfur batteries. Model parameters are identified in real life applications and parameters are compared to those of the operational Lithium Sulfur model employing Kalman filtering. The output includes an estimate of state of health and other key performance indicators. Key performance indicators are compared with measured values of for example resistance to provide feedback to the estimate process in order to improve accuracy.Type: ApplicationFiled: August 18, 2021Publication date: March 17, 2022Applicant: Oxis Energy LimitedInventors: Mark Wild, Greg Offer, Monica Marinescu, Daniel Auger, Abbas Fotouhi, Geraint Minton

Patent number: 7086842Abstract: A turbocharger having a turbine wheel mounted to a seal boss at one end of a shaft and a compressor wheel mounted to the other end of the shaft. The seal boss includes an annular face angled relative to a radial plane extending through the shaft so that as the shaft rotates oil present on the annular face is projected into an oil collecting groove in a direction radially away from the shaft and axially away from an annular passage in a housing wall.Type: GrantFiled: July 31, 2003Date of Patent: August 8, 2006Assignee: Holset Engineering Company LimitedInventor: Philip Mark Wild

Publication number: 20040057847Abstract: A turbocharger comprises a turbine wheel (4) mounted to a seal boss (19) provided at one end of a shaft (8) and a compressor wheel (6) mounted to the other end of the shaft (8). The shaft (8) rotates on bearing assemblies (13,14) housed within a bearing housing (3) located between the compressor housing (7) and the turbine housing (5), the turbine wheel (4) being separated from the interior of the bearing housing by a housing wall (3a). The seal boss (19) extends through an annular passage (20) provided through the housing wall (3a) and is sealed with respect thereto by a seal ring (21). The seal boss (19) has an inboard axial end which extends into the bearing housing and has an annular face (31) forming a radial shoulder around the shaft (8). The bearing housing has an oil collecting groove (28) adjacent the bearing housing wall (3a), having an opening (2a) at least partially surrounding the shaft (8) and axially overlapping the inboard end of the seal boss (19).Type: ApplicationFiled: July 31, 2003Publication date: March 25, 2004Inventor: Philip Mark Wild
