The present disclosure provides a system and methods for operating a power take-off unit of a vehicle from outside of a passenger cabin of the vehicle to power an auxiliary component.

An example system includes a motive application having a prime mover, a load, a driveline, and a motor/generator that couples to the driveline. The system includes a number of batteries, and a battery assembly that electrically couples the batteries to the motor/generator. The battery assembly includes a power interface positioned at a first end of the battery assembly, the power interface including a low voltage coupling and a high voltage coupling, and a service electrically interposed between the batteries and the power interface. The service disconnect in a first position couples at least one of the batteries to the first low voltage coupling and couples the batteries to the second high voltage coupling. The service disconnect in a second position de-couples the batteries from the low voltage coupling and the high voltage coupling.

Methods and systems for a vehicle transmission are provided. In one example, a vehicle transmission system includes a first planetary gear set rotationally coupled to a second planetary gear set and a first electrical machine rotationally coupled to a gear in the first planetary gear set. The vehicle transmission system further includes a second electrical machine rotationally coupled to a gear in the second planetary gear set and a first clutch configured to selectively disconnect the first and second planetary gear sets from a drive axle.

An accessory drive, including a planetary gear set with a plurality of components arranged to be concentrically disposed around a crankshaft of an internal combustion engine. The plurality of components includes: a sun gear; a planet carrier; a ring gear; and a planet gear meshed with the sun gear and the ring gear. A first component of the planetary gear set: is arranged to non-rotatably connect to a rotor of an electric motor/generator; and is arranged to connect to a power transfer component for least one accessory. A second component of the planetary gear set is arranged to non-rotatably connect to the crankshaft. For a starting mode of the accessory drive, the electric motor/generator is arranged to: rotate the first component of the planetary gear set; and rotate the second component of the planetary gear set with respect to the first component of the planetary gear set.

A vehicle transmission (1) which comprises a lubrication system and a connection for attaching a power take-off module (9) to the vehicle transmission. The lubrication system is designed to lubricate the vehicle transmission and the power take-off module (9). The lubrication system has a pressure feed (13) and a lubricant line (12) fed with lubricant from the pressure feed. By way of a first section (12A), the lubricant line (12) leads to at least one lubrication point of the vehicle transmission and, by way of a second section (12B), to a lubricant tapping point (15) of the vehicle transmission for the power take-off module. A throttle (17) and a first valve (18), connected parallel to the throttle, are arranged in the second section (12B). The first valve (18) is designed to open toward the lubricant tapping point if the lubricant pressure rises to a first pressure level.

The present disclosure discloses a power system of a new-energy vehicle and the new-energy vehicle. The power system of the new-energy vehicle includes only one driving electric motor, the power system further includes a power coupling device and an outputting device, and the outputting device includes a primary outputting device and a plurality of auxiliary outputting devices; the power coupling device is provided between the driving electric motor and the outputting device, and is configured to realize power transmission and on-off control between the driving electric motor and the outputting device; the primary outputting device is configured to provide power for travelling of the new-energy vehicle; and the auxiliary outputting devices are configured to provide power to auxiliary driving systems of the new-energy vehicle. The above technical solutions, by using the single electric motor, realize diversified outputting for the new-energy vehicle, and, by using the coupling integration technique, reduce the power sources, save the occupied space, and reduce the vehicle weight and the manufacturing cost. The technical solutions can improve the load rate of the low-speed area of the driving electric motor, thereby improving the driving efficiency. The technical solutions can effectively simplify the control logic, improve the safety of the controlling system, and realize controlling diversity.
