A personal watercraft includes a hull having a bottom wall and a side wall extending upwardly from the bottom wall. The bottom and side walls define an interior volume of the hull. A battery pack includes a plurality of battery modules. The battery pack is positioned within the interior volume. A flotation body is positioned within the interior volume between the battery pack and at least one of the bottom wall of the hull and the side wall of the hull.

A personal watercraft comprises a deck having coupled thereto a hull defining a bottom wall, a rear wall and a water intake extending from the bottom wall to the rear wall, and a jet propulsion system. The jet propulsion system comprises a housing coupled to the rear wall and defining an inlet to receive water from the water intake, a venturi, and an outlet to expel the water, and comprises a rim-driven motor disposed within the housing between the inlet and the venturi. The rim-driven motor defines a center axis and comprises a stator coupled to the housing, a rotor disposed radially inwardly of the stator relative to the center axis, and impeller blades coupled to the rotor and projecting towards the center axis, the rotor and the impeller blades rotatable about the center axis to draw the water via the inlet and expel the water via the outlet.

One example provides a protective cover for an electric vehicle. The protective cover includes a main body to selectively fit over a body portion of the electric vehicle, including over a charging port of the electric vehicle, and includes an opening extending through the main body, the opening located so as to be proximate to the charging port when the protective cover is installed on the electric vehicle, the opening to receive and enable a charging gun to be disposed at least partially within the protective cover and be inserted into the charging port to thereby enable charging of the electric vehicle without removal of the protective cover.

An electric recreational vehicle, has: a frame extending along a longitudinal axis; an electric motor mounted to the frame; a battery pack mounted to the frame and disposed at least partially rearward of the electric motor relative to the longitudinal axis, the battery pack including one or more battery modules operatively connected to the electric motor for supplying electrical energy to the electric motor, a battery enclosure containing the one or more battery modules, and at least one structural member located within the battery enclosure and delimiting at least one module-receiving section, the one or more battery modules located within the at least one module-receiving section; and a seat disposed over the battery pack and secured to the at least one structural member of the battery pack, a load transmission path extending between the frame and the seat through the at least one structural member of the battery pack.

One aspect provides a battery cooling pouch including a first thin film sheet defined as a first cooling fin having a first major surface to contact a battery cell, a second thin film sheet defined as a second cooling fin having a first major surface, and a panel insert of a polymeric material, wherein perimeter edges of the first and second thin film sheets are sealed to confine the panel insert between the first and second thin film sheets, the panel insert having a major surface defining coolant flow grooves exposed to the first thin film sheet to form coolant flow channels. The cooling pouch includes at least one interior seal between at least a portion of the first thin film sheet and the major surface of the panel insert to direct a coolant fluid through the coolant flow channels.

A distributed battery management system for a multi-module traction battery pack of an electric vehicle is provided. The battery management system comprises an analog-to-digital converter (ADC) integrated into a battery module of the traction battery pack of the electric vehicle, and a master controller external to the battery module and in digital data communication with the ADC. The ADC converts an analog signal indicative of a sensed voltage associated with one or more cells of the battery module into a digital signal indicative of the sensed voltage. The master controller performs a function associated with the traction battery pack of the electric vehicle based on the sensed voltage.

A jet propulsion system includes a housing and an impeller positioned within the housing interior. A nozzle is positioned at least partially downstream of the housing outlet and a deflector gate is positioned within the nozzle interior. The deflector gate has a first end, a second end and a pivot provided at the first end. The deflector gate is pivotable relative to the nozzle about a pivot axis defined by the pivot between a default position and a deflector position. The deflector gate in the default position having the second end downstream of the first end, and in the deflector position deflecting at least some of the water out of an opening of the nozzle in an upstream direction.

A jet pump housing is mountable to a hull of a personal watercraft. The jet pump housing comprises a body extending between an inlet and an outlet. The body has an inner wall delimiting an interior of the body and an outer wall. The inner wall and the outer wall are configured to be exposed to water during use of the personal watercraft. The body is shaped and sized to allow water to flow into the interior via the inlet and to expel water from the outlet. The body has one or more fluid passages positioned between the inner wall and the outer wall. The one or more fluid passages are fluidly isolated from the water and are in heat exchange relationship with the water via one or both of the inner wall and the outer wall.

Systems and methods of stopping propulsion of an electric vehicle in an emergency situation are provided. One method includes receiving a command to stop propulsion of the electric vehicle while the electric vehicle is in motion, and in response to the command, attempting to regulate an operation of an electric motor of the electric vehicle toward a no-load operating state of the electric motor while the electric vehicle is in motion. When the operation of the electric motor is outside a prescribed range of the no-load operating state after attempting to regulate the operation of the electric motor toward the no-load operating state, the method includes causing braking of the electric motor.

Systems and methods of communicating trip data to a rider of a powersport vehicle are provided. A method is performed at a server located remotely of the powersport vehicle and includes receiving the trip data from the powersport vehicle and storing the trip data in a first dataset associated with the powersport vehicle. The trip data identifying a route travelled by the rider with the powersport vehicle. After receiving an identification of the rider, the trip data is stored in a second dataset associated with the rider. The rider is granted access to the trip data stored in the second dataset.
