Abstract: An electric machine includes a rotor rotatable about a rotational axis, by which an axial direction is defined, and a stator with stator windings, a coolant distributor space and a coolant collector space. The coolant distributor space communicates fluidically with the coolant collector space to cool the stator windings with a cooling duct. The stator includes stator teeth supporting the stator windings and protruding radially inward from a stator body of the stator. A stator groove is formed between two stator teeth which has a radially outer groove zone extending radially inward away from the stator body into a radially inner groove zone, the radially inner zone width of which is smaller than the radially outer zone width, when measured along the circumferential direction, of the radially outer groove zone. At least one stator winding is embedded, for thermal coupling, into an electrically insulating plastic arranged in the stator groove.

Abstract: A vehicle system includes a high voltage battery and at least one control module configured to monitor the high voltage battery and command a visual warning in response to a disconnect event of the high voltage battery. The visual warning may be produced by a hazard light.

Abstract: A hybrid electric vehicle (HEV) and method of operation includes a thermal management system (TMS) that maintains optimal battery temperature operating ranges. The TMS includes a controller, heater, pump, and valves that control a flow rate of a convective fluid about the battery and other components. The TMS responds to battery temperature and differential signals, converting them into pump speed and heater signals utilizing a fuzzy logic multidimensional membership function (MF) that improves performance while reducing energy consumption by generating real-time, smoothed pulse width modulated (PWM) pump speed and heater signals. The MF capability requires less processing power than prior systems, which in turn enables improved response time to battery thermal and temperature rate changes during HEV operation.
