A system for controlling cooling of a power electronics (PE) part of an electric vehicle includes a driving load determiner configured to estimate a weight of the vehicle and to determine a driving load level based on the estimated weight, and a PE part temperature controller configured to change a cooling start reference temperature of the PE part depending on the determined driving load level.

A control system includes a power inverter configured to convert direct current (DC) power into alternating current (AC) power, an electric motor configured to be driven using the AC power output by the power inverter, and a controller configured to control the AC power by performing switching between multi-pulse control and one-pulse control on the basis of electric power loss of the electric motor and the power inverter and noise of the electric motor, the controller being a control device configured to control the power inverter.

A road vehicle with an electric drive comprising: at least one pair of drive wheels; a reversible electric machine, which can be connected to the drive wheels; an electronic power converter, which controls the electric machine; an electric energy storage system, which is connected to the electronic power converter; first power wirings comprising at least two first electric wires, which connect the electric machine to the electronic power converter; and second power wirings comprising at least two second electric wires, which connect the electronic power converter to the storage system; and a cooling system, which is thermally coupled to at least one power wiring in order to remove heat from the power wiring.

A vehicle drive system includes: a primary drive motor and a secondary drive motor; a battery; a capacitor that is connected in-series with the battery; a first power line that supplies a total aggregate voltage of the battery and the capacitor; a second power line that supplies a battery voltage; and a third power line that supplies a cell voltage. The first power line, the second power line, and the third power line are configured such that the battery voltage is higher than the cell voltage and that the total voltage is higher than the battery voltage.

An accessory component assembly is provided that includes a frame, a first vehicle accessory, and a second vehicle accessory. The frame is configured to support vehicle accessories. The first vehicle accessory is mounted to the frame. The second vehicle accessory is mounted to the frame. The frame is configured to simultaneously couple the first vehicle accessory and the second vehicle accessory to a chassis of a vehicle such that the accessory component assembly can be functionally coupled to at least two other vehicle sub-systems.

The present invention relates to a modular vehicle system and assembly thereof comprising a preassembled Body (Cabin Module) and a preassembled Chassis (Drive Module). More particularly, the present invention relates to the modular vehicle system allowing for the docking of a Cabin Module onto a Drive Module, and wherein Drive Modules can be seamlessly interchanged during the lifespan of the Cabin Module.

A vehicle includes a vehicle body, a vehicle seat, an inverter and an inverter cover. The vehicle body defines a vehicle interior. The vehicle seat is disposed on a floor of the vehicle interior. The inverter has a housing fixed to the floor of the vehicle interior at a location underneath the vehicle seat. The inverter cover is detachably attached to the inverter housing.

An in-wheel motor includes a housing 32 that is supported by two support portions 14A and 14B on a rotation axis in an inner space of a wheel and includes a heat dissipation surface at at least one end portion thereof in a rotation axis direction, and a stator core 62 that is supported between the two support portions 14A and 14B and inside the housing 32 and has an inner peripheral surface to which a distance from the rotation axis is smaller than a distance from the rotation axis to an outer edge of the heat dissipation surface.

An intelligent power generation module includes a motor having a motor housing; a cooling water flow path; a first oil flow path extending along a circumferential direction of the motor housing such that oil flows through one end portion of the motor housing; a plurality of first injection nozzles being spaced apart from each other in a circumferential direction of the first oil flow path and configured to inject the oil into the motor housing; an oil injection housing mounted at the other end portion of the motor housing; a second oil flow path formed along a circumferential direction of the oil injection housing such that oil flows inside the housing for oil injection; and a plurality of second injection nozzles being spaced apart from each other in a circumferential direction of the second oil flow path and configured to inject the oil into the motor housing.

Provided is a vehicle capable of suppressing failure of an inverter while suppressing an increase in manufacturing cost by unitizing an engine and a motor. A drive unit as a drive source for travel of the vehicle has the engine and the motor. A torque tube is connected to a rear portion of the motor. The torque tube covers a propeller shaft that is coupled to an output shaft of the drive unit. An inverter is arranged above the torque tube. The inverter is separated from the drive unit and is separated from the torque tube. A terminal of the inverter and a terminal of the motor are connected by three wire harnesses. Each of the wire harnesses has a wire length that is longer than a linear distance connecting the terminal and the terminal by the shortest distance.
