A drive train for installation in a vehicle chassis includes a power source, two motor/generators (M/Gs), an array of batteries, and a control system for configuring the drive train to operate using only the power source, only the batteries or a combination of the power source and batteries. The control system may open or close clutches to configure the drive train with each M/G working as a motor or a generator. A M/G working as a motor may use power from the batteries to supply rotational power to drive the vehicle or operate accessories on the vehicle. A M/G working as a generator coupled to a power source generates electric power for charging the array of batteries. The vehicle, including components and subsystems, may be powered electrically from the batteries or powered from the engine.

a master electronic control unit (MECU) for controlling the plurality of batteries, wherein the master electronic control unit (MECU) is communicatively connected to each one of the battery control units (BMU1, BMU2), and wherein the master electronic control unit (MECU) is configured to provide a predefined electric interference to the traction voltage bus (2) after a signal to open the at least one contactor (A, B) of each battery (3′, 3″) has been provided, and wherein each battery control unit (BMU1, BMU2) is configured to detect the predefined electric interference, and when the predefined electric interference is detected by at least one of the battery control units (BMU1, BMU2), the at least one battery control unit (BMU1, BMU2) is further configured to issue a signal indicative of that the predefined electric interference was detected. The invention further relates to an electric energy system (1), a method and a vehicle (100).

A tractor-trailer is disclosed, with associated apparatuses. A tractor may include a tractor air duct disposed underneath a cab. The tractor air duct may extend between a front opening at a front of the tractor and a rear opening at a rear of the tractor. A trailer may include a duct system that receives airflow from the rear opening of the tractor air duct and directs the airflow to a location behind a cargo compartment. An air distributor may be disposed behind the cargo compartment. An air distributor may include a fairing with openings, so that airflow from the duct system enters a space between the cargo compartment and the fairing, and exits the openings behind the trailer.

Disclosed herein is a quick-change universal power battery for a new energy vehicle. A battery body is provided with a quick-change connection port, a recessed structure, an independent liquid temperature-control loop and a multi-connection port structure. The battery body is provided with a recessed area, and the quick-change connection port is arranged in the recessed area. A power battery system is composed of no more than eight main models of quick-change universal power batteries to achieve battery selection and replacement of most new energy vehicles, and the power battery system is combined with charging to facilitate an electrical-energy supplement of the new energy vehicle. A vehicle and a replacement station are also disclosed.

The invention relates to a method for power management of an electrically powered vehicle (100), wherein at least two loads (230, 240), including a first load (230) and at least one second load (240), are by default powered by an electric energy storage system (220) of the vehicle according to a first prioritization strategy determining how power is distributed among the at least two loads (230, 240). The method comprises detecting (101) that a pre-defined operating condition applies, and in response to said detection, activating (102) a second prioritization strategy, wherein, according to the second prioritization strategy, power distribution to the first load is prioritized over power distribution to the at least one second load.

The invention also relates to a power management control unit (210), a power system (200) and an electrically powered vehicle (300) comprising the power management control unit (210) and/or the power system (200).

A materials handling vehicle including a vehicle-side charging contact assembly coupled to a battery, a steerable drive wheel defining a drive wheel track width W, and a pair of load wheels defining a load wheel gap G between the pair of load wheels that is larger than the drive wheel track width W. A charging station includes a pair of floor-side charging contacts configured to transfer charging current to the vehicle-side charging contact assembly. The pair of floor-side charging contacts define an inner contact spacing S1 that is larger than the drive wheel track width W, and an outer contact spacing S2 that is larger than the inner contact spacing S1 and smaller than the load wheel gap G to permit passage of the steerable drive wheel between the floor-side charging contacts, followed by passage of the pair of load wheels outside of the floor-side charging contacts.

A refuse vehicle includes multiple tractive elements, a prime mover, and an independent accessory system. The prime mover is configured to generate mechanical energy to drive one or more of the tractive elements.
