The invention relates to a surfboard with an electric drive (2), a battery for the electric drive (2), said battery being arranged in a battery housing (3), a first recess (4) for the battery housing (3), and a handle (5) on the battery housing (3), wherein the handle (5) is designed as a D-shaped bracket handle which is pivotally mounted on opposite sides (6) of the battery housing (3) and has a locking mechanism (7) for the first recess (4).

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied from a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes a compartment including an emission source of the fuel and a first detector arranged in the compartment to detect the fuel. If the first detector detects that a concentration of the fuel in the compartment is equal to or greater than a first threshold value, a power supply to a non-explosion-proof device in the compartment is stopped.

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied by a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes at least one compartment including an emission source of the fuel, and a vent pipe through which the fuel in the compartment is released to outside of the hull. A release port of the vent pipe is located at a position higher than a cabin or a bridge provided on the hull.

A fuel cell ship includes a storage battery compartment installed with a storage battery that supplies, to a propulsion device, electric power different from electric power by a fuel cell. The storage battery compartment is provided between a deck and a ship bottom portion of a hull.

A fuel cell ship includes a fuel cell that generates electric power by an electrochemical reaction of fuel, a propulsion device that generates propulsive force on a hull by electric power supplied from the fuel cell, a fuel supply pipe through which the fuel is supplied from a fuel tank housing the fuel to the fuel cell, a duct compartment that houses a part of the fuel supply pipe, a vent pipe that communicates with the duct compartment, and a fuel filling port that serves as an inlet for filling the fuel tank with the fuel. The fuel filling port is provided in the duct compartment.

A surfboard with an electric drive (2), a battery for the electric drive (2), said battery being arranged in a battery housing (3), a first recess (4) for the battery housing (3), and a handle (5) on the battery housing (3), wherein the handle (5) is designed as a bracket handle which is mounted pivotably around a respective centre of rotation (21) at each of the handle ends on opposite sides (6) of the battery housing (3), and in each case a lug (9) protrudes from the base side of the recess below the centres of rotation (21) inside the first recess (4), and at each handle end of the bracket handle a second projection (33) is formed, which has a curved edge (34) and which rests on the lug, and a distance between a contact point of the curved edge (34) with the lug (9).

A lease management method of an electric power motion apparatus includes acquiring location information, an advancement direction and a battery state of the electric power motion apparatus; additionally adjusting the advancement direction of the electric power motion apparatus to face towards the lease station such that the electric power motion apparatus faces towards the lease station based on normal adjustment and control if the electric power motion apparatus is located outside a lease range of a lease station; and additionally controlling the electric power motion apparatus to decelerate, and additionally adjusting the advancement direction of the electric power motion apparatus to face towards the lease station such that the electric power motion apparatus advances towards the lease station based on normal adjustment and control if a remaining power amount of the electric power motion apparatus approaches a power amount for returning to the lease station.

A connector unit for a vehicle includes a connection connector to connect an external connector, and a support member to support the connection connector. The support member includes a cover attachment part attached to a vehicle cover, and a connector support to support the connection connector.

A power assembly a base assembly including a power source and a pedestal assembly. The pedestal assembly includes a head that is removably coupleable to the base assembly, a controller positioned within the head and configured to be in electrical communication with the power source when the head is coupled to the base assembly, and a receptacle assembly removably coupleable to the head and configured to be in electrical communication with the controller when the receptacle assembly is coupled to the head for supplying power to a vessel or vehicle.

A method of controlling an electric marine propulsion system configured to propel a marine vessel and powered by a power storage system includes presenting on a user interface a plurality of power mode options selectable by a user, including at least a reduced power and an emergency power mode. Upon selection of the reduced power mode by the user, at least one auxiliary devices utilizing power from the power storage system is automatically turned off and the propulsion system is controlled so as not to exceed a first speed limit. Upon selection of the emergency power mode by the user, the at least one auxiliary device utilizing power from the power storage system is turned off and the propulsion system is controlled so as not to exceed a second speed limit that is lower than the first speed limit.
