In an output control of a hybrid-type engine generator equipped with a load output demand detecting unit, a load output demand increase/decrease determination unit and an output control unit, a configuration is adopted whereby load output demand from (output required by) the load is detected, increase/decrease of the detected load output demand is determined, discharge power from the battery is added to generated power output of the engine generator unit when detected load output demand is determined to be increasing, and output of the engine generator unit is controlled so as to use some generated power output of the engine generator unit as charge power of the battery when detected load output demand is determined to be decreasing.

A system for controlling an electric machine of a vehicle includes, among other things, a controller module configured to attenuate noise from the electric machine by altering a corrective voltage in response to feedback about the noise. The corrective voltage and a fundamental voltage command are supplied to the electric machine as a combined voltage command. The corrective voltage is on a harmonic adjacent to a harmonic of the noise.

A fuel cell system mounted on a vehicle includes a fuel cell, a fuel cell control unit having a normal mode and a meeting mode in which quietness is given a higher priority than in the normal mode, as a control mode of the fuel cell, a determining unit configured to determine whether there is a request to switch the control mode to the meeting mode, and a mode switch unit configured to switch the control mode to the meeting mode when the determining unit determines that there is a request to switch the control mode to the meeting mode.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.

A motor control device includes a motor that generates torque corresponding to a current for energizing multi-phase coils, a current sensor that detects a current value of the current for energizing the multi-phase coils, and a controller that obtains a current value of a current flowing through a predetermined coil by adding an origin learning value to a signal input from the current sensor and that controls a current for energizing the predetermined coil based on the current value. The motor control device obtains, each time the origin learning value is changed by a predetermined value, an amplitude of a predetermined order in a q-axis current of the motor based on the changed origin learning value and the signal input from the current sensor, and performs correction based on the origin learning value at the time when the amplitude switches from a decreasing tendency to an increasing tendency.

Disclosed is a motor, a control method, a power system, and an electric vehicle. Each phase stator winding of the motor includes two sub-winding sets. When a traction battery needs to be heated, the two sub-winding sets of the motor store electrical energy and provide alternating currents to the traction battery through an inverter, so that the traction battery uses its internal resistance for heating. In addition, the two sub-winding sets generate opposite magnetic fields which cancel each other out, so that the strength of the magnetic field inside each phase stator winding and the air gap magnetic flux are reduced, thereby alleviating the heat generation and NVH problems of the motor.

A diagnostic system for a vehicle includes a vehicle system configured to operate the vehicle in a normal operating mode and a boosted mode. In the boosted mode, the vehicle system increases at least one of a maximum motor torque, a maximum engine torque, and a maximum battery power available to the vehicle. A wear estimation module is configured to collect wear data associated with a component of the vehicle while being operated in the boosted mode, estimate, based on the collected wear data, wear of the component caused by being operated in the boosted mode, and generate a prediction of a remaining lifetime of the component based on the estimated wear of the component.

A battery case of a battery storage device is disposed on a vehicle floor, thereby securing an interior space. A battery module of the battery storage device can be cooled by using an interior air, thereby simplifying a cooling structure and saving a manufacturing cost. In addition, the battery storage device for an electric vehicle blocks noise generated by a cooling device and an electrical component from flowing into the interior, thereby preventing the occurrence of a passenger's discomfort feeling caused by the noise.
