An electric motor/generator includes a stator-core enclosing a rotor-core, which are each formed from stacked annular laminates. The stator-core laminates are configured to reduce vibration, and each have teeth extending radially inward from a root of an annular stator yoke/back-iron, to a flux-cap. Each tooth is formed to have opposite, lateral-edges spaced a distance-apart that changes between the root to the flux-cap, to establish a variable tooth-stiffness and a predetermined mechanical-resonance of the tooth. The opposite lateral-edges may each be configured with either a linear or a non-linear, curved edge-profile, and to have the variable tooth-stiffness and the lateral-edge distance-apart changing or decreasing between the root and the flux-cap. Each tooth may also have an edge-profile that is different from at least one adjacent tooth, and which is configured with a variable tooth-stiffness and a predetermined mechanical resonance that is different from the at least one adjacent ...

Diese Offenbarung stellt ein System und ein Verfahren zur routenbasierten Optimierung für Batterielektrofahrzeuge bereit. Es werden ein System und ein Verfahren zum Bereitstellen von Routenführung für ein Elektrofahrzeug offenbart. Das Elektrofahrzeug kann statische Verkehrsdaten (z. B. Geschwindigkeitsbegrenzung, Verkehrsampeln, Stoppschilder) und nicht statische Verkehrsdaten (z. B. Fahrzeugunfälle, Straßensperrungen, Baustellen) verwenden, um Fahrrouten zwischen einem Ursprungsort und einem Zielort zu berechnen. Die Fahrrouten können angepasst werden, um die Umgebungstemperatur außerhalb des Elektrofahrzeugs zu berücksichtigen. Die Fahrrouten können auch angepasst werden, um interne Lasten (z. B. Klimaanlagensystem oder Heizsystem) zu berücksichtigen, die durch die Batterie mit dem Elektromotor verbraucht werden können, um das Elektrofahrzeug entlang der Fahrrouten anzutreiben. Eine Anzeigeeinheit kann eine Zielfahrroute hervorheben, welche die geringste von der Batterie verbrauchte Leistung erfordern würde.
