An electric vehicle disclosed by the present specification, includes an inverter arranged outside frame members in a vehicle width direction, in a front compartment. An inner side of the inverter in the vehicle width direction is fixed to one of the frame members. An outer side of the inverter in the vehicle width direction is fixed to a cabin outer plate. Furthermore, a fixation strength of the inner side of the inverter is lower than a fixation strength of the outer side of the inverter.

A vehicle includes: at least one rotary electric machine; an inverter that drives the rotary electric machine; a capacitor connected between a paired electric power lines that is connected to the inverter; and a control unit. When a vehicle collision is detected, the control unit executes first control for discharging electric charges stored in the capacitor by performing a switching operation of the inverter so as to prevent a flow of a q-axis current but cause a flow of a d-axis current to the rotary electric machine. The control unit stops the first control in a specified case and executes second control for performing the switching operation of the inverter so as to reduce the current flowing through the rotary electric machine to be lower than that during execution of the first control. The control unit executes third control for shutting down the inverter after execution of the second control.

An electrically driven vehicle includes a first electrical apparatus, a second electrical apparatus, a low-voltage electrical circuit, a relay terminal block, and a high-voltage cable. The low-voltage electrical circuit is connected to the first electrical apparatus. The relay terminal block is positioned in the low-voltage electrical circuit so as to be electrically connected to the first electrical apparatus. A space is provided between the relay terminal block and the first electrical apparatus. The high-voltage cable is connected to at least one of the second electrical apparatus and the first electrical apparatus and is provided to pass through a space.

A wearable motorized device comprising a shoe bracket, which can be fastened to a shoe; wheels that are installed on the left and right sides of the shoe bracket in parallel to support the wearer's lateral skating and longitudinal walking; a driving motor for rotationally driving the wheels; and a battery pack for powering the driving motor. The wheels are not coaxially installed on the two sides of the shoe bracket to drive the wearer's longitudinal skating, but instead are installed on the two sides of the shoe bracket in parallel to drive the wearer's lateral skating; the wearer can position his/her legs apart during skating, so the skating stability is improved. Its general contour does not significantly exceed the contour of the shoe in the longitudinal direction, thus and it will not strain the wearer when ascending or descending stairs.

A vehicle includes an inverter, a first battery, a first power line, a second battery, a second power line, and a voltage converter. Ranges of use with respect to open circuit voltages of the first battery and the second battery do not overlap each other, and ranges of use with respect to closed circuit voltages of the first and the second batteries overlap each other. When a regenerative power output from the inverter to the first power line is supplied to the second power line via the voltage converter, and the second battery is charged, an ECU calculates a maximum regenerative power with respect to the regenerative power output from the inverter to the first power line based on the open circuit voltage of the first battery and controls the inverter and the voltage converter such that the regenerative power does not exceed the maximum regenerative power.

A magnetically de-coupled, separately controlled, electric machine assembly including a radial and one or more axial electric machines, each with rotors mechanically coupled to and arranged to directly drive a single shaft. Each of the electric machines are independently, but cooperatively, controlled by an inverter unit that includes one or more inverters. The axial and radial electric machines are contained in a single housing.

A dual-motor transmission therefor, comprising a first and a second electric traction motor, a first gear arrangement, a second gear arrangement, and a summation box. The first gear arrangement includes a shaft and at least a first gear and a second gear, wherein each of the first and the second gears can be selectively engaged and disengaged with the shaft via a clutch, and the first gear arrangement supplies a first torque from the first motor to the summation box. The second gear arrangement includes a shaft and at least a first gear, wherein the first gear can be engaged and disengaged with the shaft via a clutch, and the second gear arrangement supplies a second torque from the second motor to the summation box, and the summation box is configured to combine the first and second torques and to output a combined output torque.

A suspension structure for a power unit is configured to suspend a power unit including a motor, a transaxle, and a power control unit. In the suspension structure for a power unit, the transaxle is arranged in a substantially center portion in a vehicle width direction, the motor is arranged at a position on an upper side with respect to the transaxle, and on one side in the vehicle width direction, and the power control unit is arranged at a position on the upper side with respect to the transaxle, and on an opposite side of the motor. In the suspension structure for a power unit, the motor and the power control unit are suspended on a principal axis of inertia substantially parallel with an axis in the vehicle width direction.

An electric drive unit for a motor vehicle includes an electrical machine having a stator and a rotor. An inverter having a first switch unit energizes a first phase system (U, V, W) of the stator. A transmission is connected to the rotor for torque transmission. A lubricant circuit lubricates the transmission and/or cools the rotor. A first cooling circuit cools the first switch unit. A lubricant-coolant heat exchanger thermally couples the first coolant circuit and the lubricant circuit. A control device provides a dissipation-increasing operating mode for the first switch unit in order to increase a dissipation heating a coolant of the first coolant circuit. The lubricant-coolant heat exchanger transfers heat from the heated coolant to the lubricant circuit in order to reduce a viscosity of a lubricant.

A motor assembly includes a motor including a rotor that rotates about a motor axis, a transmission that transmits motive power of the motor to an axle, a housing that accommodates the motor and the transmission, and an oil pump fixed to the housing. The housing includes a tubular motor housing extending along the motor axis, and the motor housing includes a rib on a side surface facing the oil pump. The rib protrudes to a radially outer side from the side surface, and has a plate shape extending along the motor axis.
