Patent number: 11688899Abstract: A battery pack (e.g., a battery pack for marine environments) can include a lower enclosure having an upper wall and defining a cavity, a plurality of battery cells positioned within the cavity, a radiator assembly positioned above the upper wall of the lower enclosure, a vent in the upper wall of the cavity, and/or a valve configured to selectively facilitate fluid communication between the cavity and the radiator assembly via the vent. In some embodiments, the valve is configured to open in response to increased pressure in the cavity resulting from a thermal runaway event. In some embodiments, the radiator is configured to create a tortuous path and collect flammable particulates from the thermal runaway event.Type: GrantFiled: August 20, 2019Date of Patent: June 27, 2023Assignee: Pure Watercraft, Inc.Inventors: Richard Theodore Wurden, Marc McKissack, Andrew Rebele

Patent number: 11342761Abstract: A battery fleet charging system for charging two or more battery packs simultaneously, at independently controlled charge rates. The present invention can intelligently distribute the available charge power among multiple batteries, either symmetrically or asymmetrically, as specified by a controller that specifies and regulates the charge voltage.Type: GrantFiled: October 24, 2016Date of Patent: May 24, 2022Assignee: Pure Watercraft, Inc.Inventors: Andrew H. Rebele, Kerwin Loukusa, Keith A. Mullins, Michael V. Schaefer

Patent number: 11183739Abstract: Batteries for electric marine propulsion systems, and associated systems and methods are disclosed. A representative power system includes an enclosure having a first end and a second end opposite the first end, with each of the first end second ends including and inwardly-extending portion forming a handle region and having an opening into an interior of the enclosure. The power system can further include an electrical connector carried by the inwardly-extending portion and positioned beneath the opening of the second end, and at least one battery cell positioned in the interior of the enclosure and electrically coupled to the electrical connector. The system can still further include at least one fan positioned in the interior of the enclosure along an airflow path between the opening at the first end and the opening at the second end.Type: GrantFiled: November 13, 2017Date of Patent: November 23, 2021Assignee: Pure Watercraft, Inc.Inventors: David Milroy, Joe Sullivan

Patent number: 10511121Abstract: Cable connection assemblies for marine propulsion, and associated systems and methods are disclosed. A representative connection assembly includes a multi-conductor cable having two high voltage power conductor lines, two low voltage power conductor lines, two interlock lines, and two signal lines. The assembly further includes a connector having a connector body carrying connection elements corresponding to each of the conductor lines, interlock lines, and signal lines. In further representative embodiments, one or more of the connection elements can be housed in corresponding insulating bodies. In still further representative embodiments, the assembly can be configured so that the high voltage lines are the first to mate, and the last to un-mate, which, together with the interlock loop, can reduce or eliminate the likelihood for high voltage arcing.Type: GrantFiled: November 13, 2018Date of Patent: December 17, 2019Assignee: Pure Watercraft, Inc.Inventors: David Milroy, Joe Sullivan, Kerwin M. Loukusa, Marc McKissack, Richard Wurden
