Abstract: A charge station includes a controller that initiates charging of a battery of a vehicle and notifies the vehicle in response to an electrical parameter measured and reported by the vehicle not being approximately equal to a same electrical parameter measured at the charge station. The electrical parameter may be power, voltage or current.

Abstract: A vehicle having a traction battery and at least one electric machine for propelling the vehicle is provided. A high voltage DC bus electrically connects the traction battery to the electric machine. A controller monitors and commands power flow through the DC bus, the electric machine, and the battery. In response to a key-off event, the controller immediately discharges the DC bus by providing a current to the electric machines. This discharge continues until the voltage on the DC bus reaches a threshold. As the speed of the electric machine decreases towards a speed threshold, the voltage in the DC bus is maintained. Once the electric machine speed reduces past the threshold, the DC bus discharges the remaining voltage in the DC bus at a rate slower than the first immediate discharge.

Abstract: An internal permanent magnet machine has multiple rotor sections, each section having multiple rotor laminations. Permanent magnets are placed asymmetrically in lamination openings to attenuate oscillations in torque caused by harmonic components of magnetic flux. Asymmetry is achieved by placing adjacent permanent magnets or magnet sets on the rotor periphery with different rotor magnetic pole arc angles.

Abstract: A vehicle power module assembly including first and second power modules is provided. The first power module may include a first lock feature extending from a lower portion of a first minor side at a first central axis. The second power module may include a second lock feature at an upper portion of a second minor side at a second central axis. The lock features may be sized for interlock with one another to secure the power modules to one another. The first lock feature may be a loop element defining a through-hole and the second lock feature may be a wedge. The through-hole may be sized for the wedge to extend therein and to interlock the first power module and the second power module to one another. The first lock feature may be a flexible hook element and the second lock feature may be a slot.

Abstract: A controller, while parameters are indicative of electromagnetic interference exceeding a predetermined value, generates voltage reference vectors or duty cycle commands such that differences between switching times of any two phases of an inverter are always greater than a threshold, and while the parameters are indicative of the electromagnetic interference being less than the predetermined value, generates the voltage reference vectors or duty cycle commands such that the differences are sometimes greater than the threshold and other times less than the threshold.

Abstract: Systems and methods for operating an electric drive system for an electric or hybrid vehicle is described. In one example, the drive system is operated by suppling a pulsed torque current command while supplying a zero flux current command. The torque current command and the flux current command make up winding current commands for an electric machine.

Abstract: An electric drive system is actively controlled while an electrified vehicle is being towed. The inverter switches are manipulated to preclude exceeding a maximum voltage of a DC bus and also to preclude exceeding a maximum phase current magnitude. During a transition from an inverter off state to a short-circuit state, field-oriented control is utilized.
