BEVs

I appreciate the BEV mostly because they...

It's not had a lot of discussion here, but there are two battery chemistries in common use in cars: NMC and LFP. NMC batteries are the ones used in eBikes where weight matters but they need careful looking after to get good longevity and to avoid catching fire etc. LFP batteries have lower energy density (so packs are heavier) but have better longevity and arguably less likely to catch fire. Tesla, MG and the new Citroen eC3 use LFP, most others (Nissan, Renault, Hyundai) seem to use NMC however I saw an announcement that Renault will use more LFP in future.
...
Tesla have used several different types:

Yep,I watched it last week and thought it funny that the bike burst into flames whilst being ridden rather than when being charged which is the usual source of fire on vehicles with cheap(Chinese)batteries.I wondered if it were the motor that overheated and caught fire and not the battery(?)
Most likely the battery overheated -- should've cut out when it reached a preset temp. Or some of the terminals were underrated for the current and the localized heat started the chain reaction in the batteries. Bad design probably.

My bold.
Yep there's a lot of such bad design out there,usually Chinese,though Tesla is no bench mark to look up to :roll: :wink:

GBP prices have been announced. £18K for the small battery, £19.8K for the medium battery, £21.5K for the large battery.

I hate how heavy BEVs are, and really like the new one tonne Dacia Spring (NMC battery) but suspect the battery in the eC3 will last longer, particularly if making use of rapid charging.
I agree, the Dacia will suit those with shorter journeys.

It's long been possible to buy a cheaper ICEv in a manufacturer's range and use for very long journeys without any effect on its life, or the life of its components. A friend used a Toyota Yaris for over 20 years and well over 200,000 miles - the only part it needed (other than consumables) was a £20 exhaust manifold. It was still on its original clutch when scrapped, despite two of his children having learned to drive in it, and his son having used it intensively for a couple of years. Had the body been galvanised, it would still be on the road.

Jules59 wrote: 7 Jul 2024, 10:46pm What sort of depreciation are BEV owners finding when part exchanging etc ?
Its usually the largest on-going cost in the early years of a vehicle's life.

I saw on youtube that a £75K Audi Etron (? spelling) had lost £55K in 4 years with only 35k miles on the clock.
But that may well not represent the general trend in BEV depreciation, hence my question.

At some point I'll probably have to go electric but my car is only 10 years old with only 60K miles and have been very reliable as I service it myself and so I hope it will keep going for another 10 years.
The bubble of BEV sales after £billions were printed hasn't lasted and present economic woes after such a huge amount of cash printing together with rises in energy prices have hit BEV sales hard with their high retail prices and higher insurance costs. It will be interesting to see how healthy sales are of cheaper battery cars like the Dacia Spring and other European smaller cars. BYD are reported to be intending to manufacture in Turkey to circumvent EU and UK import tariffs, as are so many TVs and washing machines for the European market.

The market for second hand battery cars will take time to stabilise as technology continues to develop, it could be higher than for engined cars due to battery life becoming more of a concern the older the vehicle grows. Until someone brings out a car which has a life of 25y-30y, who will wish to spend a five figure sum (or close) on replacing the battery in a 13 year old car?

The BMW i3 is possibly the BEV with the longest life potential with its CFRP shell and aluminium chassis, but will the electronics, wiring and connections last the course? One corroded, hidden earthing point or connector can create a nightmare of faults and diagnosis in a modern vehicle with its computerised electrical wiring.

Strangely, the large battery version of the Microlino is the most appealing since it will provide the most longevity as well as the greatest range. So that's £21.5K for a 15 KwH battery. Whereas the Silence is £16K for an 11.2 KwH battery. My problem with the Silence is the slow 1.2 KwH charging, the Microlino is 2.2 KwH charging. Silence are upping production to 20K units per year.

pushing the right joystick forward turns right, and pushing the left joystick forward turns left
could be interesting as I think tank-steered velomobiles do the opposite :shock:

Yeah,seems counter intuitive but I s'pose you'd get used to it.

I like the aerodynamics but pedalling isn't going to do much since it weighs 600kg. I'd be happier with a wheel in each corner.

Exactly my thoughts too.
