A combined cooling and water braking system for a vehicle comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.

A pressure vessel assembly including a pressure vessel including a cylinder part and a first side part and a second side part, the first side part and the second side part each having a dome shape and being provided at two opposite ends of the cylinder part, nozzle members respectively provided on the first side part and the second side part, and a plurality of protectors connected to the nozzle members and configured to surround a respective outer surface of the first side part or the second side part.

A refuse vehicle includes a vehicle chassis and an all-electric vehicle body on the chassis. The body includes a hopper, a refuse storage container, and a plurality of electrically powered body systems. The body systems include an electrically actuated tailgate, an electrically actuated refuse loading assembly, and an electrically actuated refuse packing assembly configured to remove refuse from the hopper and to pack said refuse in the storage container. The vehicle (e.g., vehicle body) further includes a power management module configured to regulate energy usage of the body systems and/or to record and track electrical energy usage in the body systems.

A throttle valve for adjusting the feeding of a gas to a fuel cell, which includes: a valve body, divided into a first and a second portion; a gas feeding duct obtained in the first portion; a throttle plate arranged in the feeding duct; a shaft which is rotatably mounted in the first portion and supports the throttle plate; and an actuator which is mounted in the second portion and is configured to rotate the shaft. The throttle valve further comprises a magnetic joint, which transmits the motion from the actuator to the shaft and is divided into a first half coupled to the shaft, and a second half facing the first half and coupled to the actuator. The throttle valve also includes an insulating wall which insulates the first partition, in a pneumatically sealed manner, from the second portion of the valve body and is arranged between the two halves of the magnetic joint.

A hybrid plug-in battery and hydrogen fuel engine vehicle with swappable modular hydrogen tanks and integrated with solar power generation system synergistically combines the advantages of electric vehicle, the solar powered electric vehicle, and the hydrogen fuel engine vehicle. This combination of battery electric vehicle and hydrogen fuel engine vehicle mitigates the issues of prolong charging time of battery electric vehicle and prohibitive high cost of fuel cell electric vehicle. This hybrid configuration of vehicle is able to take advantages of the electric vehicle charging station infrastructure and the hydrogen charging station infrastructure simultaneously. The introduction of the water electrolysis system into the new structure of the hybrid vehicle enables onboard hydrogen generation; has the advantage of conventional hybrid vehicle, but without using fossil fuel. The swappable hydrogen tanks comprise sensors and wireless communication electronic terminals to be shared by all vehicles.
