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.

The invention provides in some aspects a transport system comprising a guideway with a plurality of propulsion coils disposed along a region in which one or more vehicles are to be propelled. One or more vehicles are disposed on the guideway, each including a magnetic flux source. The guideway has one or more running surfaces that support the vehicles and along which they roll or slide. Each vehicle can have a septum portion of narrowed cross-section that is coupled to one or more body portions of the vehicle. The guideway includes a diverge region that has a flipper and an extension of the running surface at a vertex of the diverge. The flipper initiates switching of vehicle direction at a diverge by exerting a laterally directed force thereon. The extension continues switching of vehicle direction at the diverge by contacting the septum. Still other aspects of the invention provide a transport system, e.g., as described above, that includes a merge region with a flipper and a broadened region of the running surface. The flipper applies a lateral force to the vehicle to alter an angle thereof as the vehicle enters the merge region, and the broadened region continues the merge by contacting the septum of the vehicle, thereby, providing further guidance or channeling for the merge. The flipper, which can be equipped for full or partial deployment, is partially deployed in order to effect alteration of the vehicle angle as the vehicle enters the merge.

Systems and methods are provided for charging a battery. The system, for example, includes, but is not limited to a first interface configured to receive a voltage from an AC voltage source, a matrix conversion module comprising a plurality of switches electrically connected to the first interface and configured to provide a charging voltage to the battery, and a controller communicatively connected to the matrix conversion module, wherein the controller is configured to: determine a voltage of the battery, determine an angle of the AC voltage source to initiate charging of the battery based upon the voltage of the battery, and control the plurality of switches to provide the charging voltage to the battery between the determined angle of the AC voltage source and a subsequent zero-crossing of the AC voltage source.

A motor drive device includes: an inverter circuit having a smoothing capacitor; a drive circuit portion which outputs an operation signal to the inverter circuit; a control portion which controls the drive circuit portion; and an operating voltage generation portion which supplies power to the drive circuit portion and the control portion by generating an operating voltage for the drive circuit portion and the control portion. The inverter circuit converts a DC voltage from a first power supply to an AC voltage and outputs the AC voltage to a multi-phase motor coil. The control portion outputs a signal to the drive circuit portion according to a command value from a high-level control device operating on power from a second power supply outputting a voltage lower than the first power supply. The operating voltage generation portion is capable of generating the operating voltage using power fed from either of the first power supply and the second power supply.

In an angular section where the output voltage from an inverter device is linearly approximated with the zero cross point as the center thereof, a PWM generator in the inverter device changes either the time interval between the centers of PWM ON pulses or the time interval between the centers of PWM OFF pulses depending on the inverter operation state. An electric vehicle is equipped with the inverter device, which drives a motor.

The present invention provides a start control system of a vehicle, including: an electronic control unit (ECU), a starter, an air conditioner, and a starting power supply. The starting power supply includes a starting battery and a battery management system (BMS). At a low-temperature environment, when receiving an ignition request signal sent by the ECU, the BMS detects the temperature of the starting battery. When the temperature is less than a preset threshold, the starting battery is connected to the air conditioner for a preset time, so that the starting battery effectively raises the temperature of the starting battery by means of discharging at a high current temporarily. The start control system of a vehicle improves an ignition capability of a vehicle in a low-temperature environment, extends a temperature range and an area of using the vehicle, and improves competitiveness of the vehicle. The present invention further provides a vehicle having the start control system of a vehicle.
