A vehicle-body structure may include a floor panel, a center frame disposed to be higher than and away from the floor panel, and an air-conditioning device. The air-conditioning device may include an air distribution portion that is positioned higher than a front portion of the center frame and distributes generated air-conditioned air to each portion of an occupant space, and under-feet ducts that guide air-conditioned air to a lower side. The under-feet ducts each may extend downward from the upper side of the center frame through a vehicle-width-direction outer side of the center frame.

A dual drive unit may include two motors, two power transfer mechanisms, and two output shafts. The output shafts are co-linear. The dual drive unit may include two single drive units, which may be similar to each other, coupled together at a joint, which may optionally include a clutch. A drive unit may be modular, and various components may be combined to provide power to an output shaft. For example, a drive unit may include a differential at a first interface, which may be removable, and two drive units may be coupled together at the first interface. A drive unit may have a Z configuration, wherein a motor on a first side of a vehicle powers a wheel on an opposite side of the vehicle.

Methods and systems are provided for a vehicle air duct. In one example, a system for a vehicle, includes a passage comprising an inlet at a downstream portion of a front wheel well of the vehicle and an outlet upstream of a rear wheel well of the vehicle.

Pump module, particularly for a temperature management system, and temperature management system comprising the pump module, and motor vehicle comprising the pump module or the temperature management system

The invention relates to a pump module, in particular a liquid fluid pump module for a temperature management system (100), e.g. of an electric battery-driven motor vehicle or a hybrid motor vehicle, comprising: at least one electrically driven fluid pump unit (2) which is configured and provided to supply fluid to be pumped to at least one actuatable fluid valve means (3); a control device (ECU) for actuating at least one drive motor (7) of the fluid pump unit (2), wherein the control unit (ECU) also comprises at least one electrically actuatable operating solenoid (31) for a pilot valve (20), which solenoid is configured and provided to hydraulically operate the fluid valve means (3) by means of the pilot valve (20) during normal use of the pump module (1).

Furthermore, the invention relates to a temperature management system comprising the pump module, and a motor vehicle comprising the pump module or the temperature management system.

An electric vehicle may include a battery module, a heat transfer circuit, and a ventilation system. The heat transfer circuit may include a first heat exchanger, a second heat exchanger, and a reversing valve. The first heat exchanger may be adjacent to the battery module and/or in thermal contact with the battery module. The second heat exchanger may exchange heat with an environment external to a cabin of the vehicle. The reversing valve may reverse a fluid flow direction of the heat transfer circuit. The ventilation system may force air across the first heat exchanger or the second heat exchanger and direct the air into the cabin of the vehicle.

A vehicle includes an electrical powertrain, a heater, at least one cooling loop, and a controller. The heater is configured to heat a vehicle cabin. The at least one cooling loop is configured to transport waste heat from at least one subcomponent of the electrical powertrain to the vehicle cabin. The controller is programmed to, in response to a command to heat the vehicle cabin and a command to operate in an economy mode, shut down the heater and operate the at least one cooling loop to transport the waste heat to the vehicle cabin. The controller is further programmed to, in response to the command to heat the vehicle cabin and an absence of the command to operate in the economy mode, operate the heater to heat the vehicle cabin.

A heat management system and an electric vehicle. The heat management system may be configured in the electric vehicle. A plurality of heat management requirements are generated under different conditions such as different operating conditions (such as driving and a charging request) of the electric vehicle, a current ambient temperature of the electric vehicle, a temperature of a battery pack, or a heat status (that is, a heat value) of a power assembly. Therefore, the heat management system can select different circulation manners of a coolant for different heat management requirements. The heat management system adjusts opening or closing of each valve port in the multi-path direction control valve assembly to select different circulation manners of the coolant, to reduce energy consumption and costs generated when the heat management system performs heat management on the power assembly and the battery pack.

A drive unit includes: a rotating electric machine having a rotation axis extending in a horizontal direction; a rotating electric machine case; and a power conversion device. The power conversion device is arranged on one side of the rotating electric machine in an orthogonal direction. The power conversion device includes a first connector to which a first electric power line through which electric power supplied to the rotating electric machine and electric power supplied from the rotating electric machine flow are connected. The first connector is provided on a first end side and is arranged to protrude from the power conversion device at a predetermined angle in a direction away from the rotating electric machine in the orthogonal direction, as the first connector goes away from the power conversion device in the rotation axis direction, when viewed from above.

The invention relates to a housing (1), in particular for an electric drive system for a vehicle, wherein the housing (1) is configured as a system housing and is provided for receiving a plurality of system components, and wherein the housing (1) has a housing wall (11) which is produced by way of a casting mould, and a plurality of interfaces for connecting the housing (1) to components which are situated outside or inside the housing (1) are provided in or on the housing wall (11). Furthermore, the invention relates to the use of a housing (1) as a system housing for an electric drive axle of a motor vehicle.

A method for controlling an electric vehicle driven by a plurality of electric motors including a first electric motor, in which a lubricant, which is used for lubricating the electric motors and power transmission systems therefor, is used for cooling the electric motors is provided. The method includes setting torque distributions for the plurality of electric motors on the basis of a driving force required by the electric vehicle controlling the drive of the plurality of electric motors on the basis of the set torque distributions and circulating intermittently the lubricant used for cooling the first electric motor when the torque distribution set for the first electric motor is smaller than a predetermined value which is regarded as a reference value.
