If JLR builds its EVs like they build cars now there will still be lots of warranty work. Jules Last edited by jules on 13th Aug 2022 11:16 am. Edited 1 time in total |

Very true, after almost seven years our i3 has only ever seen the dealer for the two yearly service/inspection, nothing has needed replacing* or repairing. But of course if you wanted to “tinker” the still have conventional brakes, suspension, lights and wipers* etc, * I must admit I have replaced the front wipers once and even unblocked the washer fluid filter, myself…..not a garage. What shock horror on an EV? Regards David Lovely i6 has now gone, but not me...... Please let me know if anything in my post offends you, as I may wish to offend you again...... |

We all believe that nothing will change, and all our hard won skills will be needed forever.

Indeed it does, one of the main reasons we love the i3 is due to its purity of engineering concept, n aluminium chassis and suspension components and a carbon fibre passenger cell with all outer panels of plastic, it made for a lightweight very efficient and unique EV, the fact we also liked the odd looks made it an easier choice. I’ve also still got a few pots of grease in the shed, Girling Red Rubber grease, Moly and various grades, no grease gun anymore, which was a mistake as my new off-road mobility buggy uses grease nipples @AT1963……I get it you don’t like EVs or at very least think of them as the spawn of the devil, but does it matter very much to you if others do?

Whether you like it or not everything has a life expectancy and a vague limit, for electronics it's about 7 years MTBF, it is low due to the initial failures in the first 3 to 6 months, your electronics will probably last about 12 to 15 years as most of you with FL2's have found out, anything with an electric motor is slightly different, though washing machines and tumble dryers have extremely long lives those fitted to EV's may or may not achieve those lives, electric motors are great at constant temperatures but start throwing high currents at them then the life shortens this is due to localised heat produced due to high currents, high currents are caused by rapid acceleration and the longer you accelerate hard the more heat is produced this in turn heats the motor windings which expand and cause the windings to rub together which slowly but surely wears or cracks the insulation eventually causing the motor to short and fail.

This is how you should make an EV (its in three parts) BMW I3 Manufacturing

I would think the motor in a good EV will last basically forever. If you're using the washing machine motor as an example, then those things do last years, and they're not well made, or use expensive components, they're almost all brushed universal motors too, mass produced for a few Pence per unit, bus last years spinning upwards of 50,000 RPM, without cooling. An EV motor on the other hand isn't cheaply made, and isn't a brushed motor either. They're all pretty much 3 phase induction motors now, some use magnets, but most EV manufacturers are moving away from permanent magnets, and over to induction. A typical EV motor doesn't spin more than 20k RPM, and are liquid cooled, so shouldn't get hot in normal circumstances. If anything is going to fail on an EV, I would guess that the inverter's BJTs will fail first, as those are really highly stressed components. Hyundai Ioniq 5 Ultimate. The family car. 2009 Rimini Red SE TD4. Gone. 2006 Tonga Green i6 HSE. Gone. Audi A5 convertible, my daily driver. 1972 Hillman Avenger GT, the project. |

Interesting programme from 3 knowledgably involved engineers on EVs and the future.
