I would imagine if there is oil in the electric motors that is “lifetime” but test really probably 300k miles, so if you drive the car into the ground, you probably would want to service that at some point, assuming they are serviceable without destruction.
- angry_octet 20d agoThere's no oil in electric motors. The only significant oil is for the reduction gearbox, but as it doesn't change gears the wear is very low. First change will pull out some metal I'd guess, quality of machining dependent. Every 60000km/2Y, 1-2 litres. Batteries may be immersed in a high dielectric thermal fluid, which will experience some breakdown but over a long time period, more than 10Y.
- formerly_proven 20d ago> There's no oil in electric motors. Many EVs use hybrid water/oil cooling, typically water for the stator and oil mist/spray for the rotor and exposed parts of the windings.
- angry_octet 20d agoPlaying with semantics. Oil isn't lubricating anything. There is grease in the bearings and the gearbox.
- formerly_proven 20d agoI doubt there's ever been a production car that used grease in the gearbox. Not outside the 1890s, anyway.
- angry_octet 18d agoWhatever buddy.
