This is so cool to see, I am fascinated by how simple and practical electric motors are one 4x4s. Great work, I am super excited for the final product!
I like the. Way you. Did this convertio n.. To. Electric. And the. Way. You. Still. Retained.. The. Part. Time. For. Wheel. Drive.... From Jeremy. In. England
Thanx, have an all original DBG SIIa -65 without engine (was a V8 in it) and seriously wanting to go down this road. Most important is to make the conversion reversible though.
this is great, i would to love do this to my series 3, just curious by reducing the rpm limit on the motor does that give you longer battery time/distance per charge ?
Really good stuff ... But actually engine clutch is predefined with company to install... Where as mounted the motor what customizations that you made to install the clutch.. Please reply
Very clear explanation, thanks! Just ONE question; while the torque/rpm is limited by software, which is very understandable due to the heavy gearbox, is this method lowering the regeneration rate of the motor as well or not affected?
I thought about this setup for my 4x4 and wondered. Is it maybe not better to get the dual shaft motor, position it where the gearbox is and run the drive shafts directly from it to the rear and front diffs? Taking into account the diff gear ratios, I'm sure they are the same front and back, choosing the correct size motor, so that the peak torque and hp happen at the correct rpm, giving preferable speed and power at the right time. The only issue would be if wanted to run rear wheel drive only (I've got front free wheel / locking hubs), then you either install two smaller separate motors front and rear or find a way to disconnect the coupling on the front drive shaft to disengage front wheels when needed. Thanks for the video, looks cool.
I looked into that for my 1969 Land Rover (Series 2a). Gearing ratio doesn't work connecting directly to the differentials, even with the high 4.7:1 ratio on these old rovers. All the research I've done (and advice I've gotten from several conversion outfits) is that you want about a 9:1 overall ratio from electric motor to wheels to make a fixed gear scenario work. This allows you to start with reasonable torque and cruise at highway speeds and everything in between. I'm heading down the road of connecting a HyPer9 directly to the transfer case, which means ditching the transmission. The transfer case I have (came from a Defender) has a high and a low setting. High setting has a 1.41:1 ratio, and the low has a 3.32:1 ratio. Should cover all my needs!
Did you ever consider a 2:1 underdrive in the transfer-box and forget the clutch/gearbox yet still keep 4wd and high-low range? I'm only at the daydreaming stage with my 109 StatWag conversion but was wondering about pulling away on a hill and 8000rpm noise at 70mph. You appear to have way more resources than me so I guess you went through all these scenarios before settling on your final configuration. I'd be interested in your/anyone's thoughts.
Looking good indeed. I'm surprised you didn't jettison the transmission and drive the hi/lo range centre diff directly. Less weight, less things to go wrong and more options for locating batteries? As a guestimate, the torque would be similar to the original ICE motor in hi range and lo ranges. At worst a cog swap for the hi/lo range to get a little more torque if really required.
So what is the name of your website so anywhere part of the world one is one can order any parts one might need, Depending on the series of land rover one has got???
Good work but its sad you didn't pick a better off road vehicle with coil springs and heavy duty drive train like a cruiser or patrol. I guess a defender with patrol diffs would be the ultimate.
Let's look at viability for your desire : take a 109 County '70's model restored and converted . Is there going to be the market at the mid-hundred grand to get the doors open and employ you guys in this venture ? What's the possibility of just using a third party petrol engine ( like Morgan , TVR , Birkin and others do ) to re-birth old Series Landies and buyers won't be restricted with recharging and will have engine noise and unlimited travel ?
Theres some great petrol and diesel conversions for these - even the Holden motors they swapped out back in the 70s were an improvement. A few workshops offering ICE conversions/upgrades these days. We're booked out till the end of next year with the electric conversions.
It might build better consumer confidence if your hair wan't doing 90 in a 30 mph zone, best achieved from crossing the lead with the neutral wire with a screwdriver! Dust the motor turn in the other direction due to the Southern Hemisphere? Cheers!
