A boil-off management system for a cryotank includes a boil-off conduit which is fluidically connectable to a cryotank via a boil-off valve. The boil-off management system further includes an air feed conduit and a mixing chamber for mixing a first medium (e.g., hydrogen) flowing in through the boil-off conduit with a second medium (e.g., air and/or oxygen) flowing in through the air feed conduit. A catalytic converter is arranged downstream of the mixing chamber and an outlet downstream of the catalytic converter. At least one enrichment apparatus is provided and configured to temporarily increase the proportion of the first medium flowing in through the boil-off conduit in relation to the second medium flowing in through the air feed conduit at the catalytic converter.

A green zone exists in which traveling of a vehicle using an amount of electric power that has a greenhouse gas emission intensity greater than a regulatory limit is restricted. A server includes. I/O ports through which the emission intensity of the electric power supplied from an electric vehicle supply equipment is obtained; and a processor that associates the amount of electric power charged from the electric vehicle supply equipment to a battery with the emission intensity obtained through the I/O ports. The processor: determines, based on an amount of electric power having an emission intensity less than the regulatory limit within the amount of electric power stored in the battery, whether a vehicle should be permitted to travel in the green zone; and notifies a user of the vehicle of a determination result.

The present disclosure relates to systems and methods for managing a state of charge of a hybrid vehicle battery using an eCAT. Electrical energy is provided to a hybrid system for storage at the battery of the hybrid system. A first state of charge of the battery of the hybrid system is determined. Upon determining that the first state of charge is within a predetermined upper range, a determination is made as to whether to increase energy supplied to one or more hybrid vehicle components, the one or more hybrid vehicle components comprising at least the eCAT. At least a portion of the electrical energy is consumed at the eCAT.

A method for operating a drive system of a hybrid vehicle is provided, which comprises reserving, by a controller of the drive system of the hybrid vehicle, electrical energy stored in a traction battery of the drive system and intended for an electrical heating of a catalyst of the drive system. A controller for a drive system of a hybrid vehicle to carry out such a method is also provided.

A marine vessel, system, and process provides for reducing or eliminating fuel consumption and emissions of marine vessels. System and method for charging an electricity storage element of an energy storage system of a floating marine vessel may include applying a power source from a marine platform to an electrical power bus of the floating vessel to charge the electricity storage element. A power generator of the marine vessel configured to supply electrical power to the power bus may be configured from an ON state to an OFF state.

A powertrain control system is provided for a vertical take-off and landing aerial vehicle for urban air mobility. A powertrain of the vertical take-off and landing aerial vehicle is a hybrid type powertrain, in which the output shaft of a rotor driving motor is directly connected to a rotor, a battery is connected to the rotor driving motor to supply power thereto, and an engine and a generator are connected to a battery to charge and discharge the battery. The driving of the engine and the generator is controlled based on required power of the motor and the SOC of the battery in each flight step of the vertical take-off and landing aerial vehicle, and the SOC of the battery is constantly maintained at a predetermined level or higher.

Methods and systems are provided for limiting requested wheel torque during startup of a vehicle having an electrified powertrain. In one example, a method may include, responsive to a discharge power currently available being less than or equal to a threshold discharge power, operating the vehicle while requesting the wheel torque at a feedforward torque limit, the feedforward torque limit being based on the discharge power and a threshold vehicle speed. In this way, large shifts in wheel torque may be avoided upon startup of the vehicle, thereby reducing noise, vibration, and harshness at the electrified powertrain.

A vehicle includes a battery to which electric power supplied from electric vehicle supply equipment is charged. A green zone exists in which traveling of a vehicle using an amount of electric power that has a greenhouse gas emission intensity greater than a regulatory limit is restricted. A server includes: I/O ports through which the emission intensity of the electric power supplied from the electric vehicle supply equipment is obtained; and a processor that associates the amount of electric power charged from the electric vehicle supply equipment to the battery with the emission intensity obtained through the I/O ports. The processor: permits the vehicle to travel within the green zone using an amount of electric power having an emission intensity less than the regulatory limit within the amount of electric power stored in the battery; and notifies the vehicle of information related to that amount of electric power.
