Electric Defender 90

[goingbush]

Not much gives it away ! Vienna, Austria.

55kwh of Tesla modules , 120km range ( mine uses 30kwh / 100km)

still has gearbox & transfer case, no motor / controller details

It might be sacrilege (and apologies if it is) but if I had the $$ and space to I'd EV one of these;

So an EV conversion will most likely become common place? ...what is the consensus on what it might cost for an EV conversion? And when will it become an affordable, easy option?

...We’re about to go from being concerned about all the new electrickery and it’s reliability, to nothing but ekecktrickery! What will EV reliability be like compared to ICE?

Would there be a great deal of cost difference in an EV conversion in, say, a paddock basher or at best 'toy' for short trips to town as opposed to a full blown diesel replacement use?

Electrics are ULTRA Reliable, no cooling , exhaust , alternator , etc etc . Brakes will be far more reliable and last magnitudes longer because regen does nearly all of the braking. Friction brakes only needed to come to a complete stop or hold on a hill.

The motor and controller should last several lifetimes so long as not overclocked by "performance tuners" ( Tuners are now getting upwards of 2000Nm out of Nissan Leaf motors) LiFePo4 Batteries will last upwards of 300-500,000km if you don't abuse them . Better battery tech coming along soon.


As for all the useless added on crap that manufacturers think people think they 'need' that will be the same reliability as for any modern car & then there is bound to be built in obsolescence.

[manic]

Yeah, but can you push start them when the batteries flat? [emoji39][emoji39]

The alternator is usually replaced by a dcdc charger, how much more reliable is that system - all depends

On a diesel, the fuel pump could fail. On elec the charge controller could fail.

If you put a IP rated good quality e-motor in an old landy, with a simple battery and charging system, it should be as reliable as a well maintained diesel, but with far less servicing required and cheaper to run.

But set it up like a Tesla with automatic smart internet connected everything and you are asking for trouble.

the cost difference would be in the batteries. The more range , the bigger the traction pack = higher cost.

12 months ago I paid $392 per kwh of Prismatic LiFePo4 battery storage , Todays prismatic rate is down around $300 ,

A Tesla uses about 20kwh per 100km so if you want 500km range you will need 100kwh of battery = $30,000 of battery
Obviously Tesla make their own batteries and are a LOT cheaper than Prismatic cells that I bought .

My Landy conversion gets about 30kwh per 100km , I have 28.8 kwh of battery = 96km range ( I paid $11,000 in batteries, my total conversion cost was about $22,000)

So its not cheap ( but a lot cheaper than a $45,000 LRA Chevy LS Conversion) and your not going to do it to a paddock basher, You will only do it on a car you love & will keep for the long term.

Wait a few years till theres a supply of smashed Nissan Leafs to use the Motors & batteries from. (or import them from Japan now)

There are no moving parts in a DC -DC converter no reason that wont last for ever, I bought 2 because they were so cheap but know I'll never need to replace it.

A quality A/C electric motor will last millions of km or a hundred years with zero maintenance, A well maintained diesel by definition needs regular maintenance (and repairs as necessary)



But set it up like a Tesla with automatic smart internet connected everything and you are asking for trouble.



Exactly , you don't need any of that smart rubbish in any car IMO,


The only problem I can see , and its a likely scenario , what if your charging & the power line gets hit by lightning.

Cheers GB, very helpful.

So theoretically battery tech will become much more affordable as the market increases as will electric motors...making converting vehicles to EV with a decent range a financial reality down the track.... Many spend $20k or more on upgrading components / accessorising their 4x4's now anyway.

How much does a new Nissan Leaf engine cost and what battery does that come with? ...would that be a realistic option for a non-tech minded person to have their Defender or Discovery converted EV now? Or would you wait a couple of years?

Some teslas have had the dcdc charger fail. They can run hot, need to be watercooled, and can fail. But this is an example of an overly complicated system where the dcdc can put out as much as 200amps to run all the onboard systems.

Yes, I read in the Tesla Owners Manual that when parked up you need to leave the car plugged in as the onboard electronics will deplete the 12V battery , The car wakes up & charges the 12v battery as it gets low .

The biggest fail on Teslas is the 12V Lead acid battery , Why the hell don't they use Lithium ??

I had a 12V SLA 18Ah Motorbike battery in my conversion & I worried the 50 Amp DC-DC was too much for it as it exceeded the safe Lead Acid charge rate, So replaced it with a Motobatt Lithium , about 1/4 the weight, Much better & it switches itself off if it gets below 11.4V so instead of the immobiliser drawing it down it will turn off to protect itself . The car wont turn on with a flat 12v battery but the traction pack cells will happily sit at 3.2V for years, they don't need a float charge to stay healthy.

Think Engine = ICE , Motor = Electric . I doubt you could buy a new Leaf Motor ,
Its cheaper to buy a $5000 Salvage Leaf just to Harvest the Motor & Batteries, basically throw the rest away unless you can hack the controller & CANbus,
The motor can be separated from the east west transmission and has a splined shaft that can be coupled to an existing gearbox or Transfer case .

My bad, yes motor. Ok so I figure it’s a few years off for mainstream conversions. I’m interested, just don’t have the knowledge to go down the path you have. ...maybe when it’s time to replace the 300 Tdi.
