In for the read.
Have you read about graphene batteries?Agree, no way that batteries can match gas in volume or weight. But I can't help but wonder how much gas a trail rig uses sitting still and waiting.
I have. All the new battery stuff, whether graphene, carbon nanotube, air based, seem to be "just a few more years."Have you read about graphene batteries?
If it comes to fruition there will be a lot more electric cars in driveways. BUT, i dont think our grid is capable of the instantaneous draws these batteries charging will do.
Multiple articles liken them to a cross between a supercapacitor and a battery. Ive reading updates about it for a few years now.
Also in for the read.
I want to convert a classic to electric but i feel like we are in the 1980s light duty diesel era for electrics (think buick diesel)
ill agreeI have. All the new battery stuff, whether graphene, carbon nanotube, air based, seem to be "just a few more years."
I've seen some batteries that have graphene in them for sale in the last few years, but I don't think I have seen any graphene based ones yet.ill agree
I remember about 15 years back they figured out how to make diesel from shit coal, the coal nobody will use. And im gonna guess that it was too expensive on a large scale but it never came to fruition.
I have seen some small graphen batteries or hybrids on a small scale.
But i seem to remember in a article a year or so back talking about how the thought was the battery could take any shape, so you could make components like the base floor of vehicle the actually battery instead of a skid like is in most electrics now. With them being no volatile like LI are its seems like you would get a carbon fiber-esk battery...
ill agree with all that.I've seen some batteries that have graphene in them for sale in the last few years, but I don't think I have seen any graphene based ones yet.
I haven't seen anything about any shape, but it makes sense that they are trying for it. I have seen that they are trying to develop structural batteries with not much success.
Either way, this stuff is all still in the lab and is not feasible for anyone with any sort of budget.
I tested my EV Land Cruiser for the first time today. It works!
Yes, yes, and yes, lol. I thought of all this stuff believe it or not it is first gen 80kw with 2015 24kwh battery. Upgrades in the future after it actually works.The posts from yesterday got deleted, so I didn't see if you answered or not, but which leaf motor and battery pack are you using? Google tells me that the first gens came with a 110HP 210FtLbs motor and either a 24 or 30kWhr battery while the second gens had a 147HP 236 FtLbs with a 40kWhr battery or an optional 215HP motor with a 62kWhr battery pack. Also, are you using the built-in ~8:1 gear reduction on the motor, or do you have it directly coupled to the T-case? Seems like your final drive ratio is going to be too low with the differential gearing if you kept the 8:1 reduction, or too high if you removed it unless you are planning on running one of your reduction boxes in low on the street.
I assume you divorced the drivetrain from the motor because it was cheaper and easier than custom building and adapter housing and spud shaft? Where did you mount your batteries? Do you have any idea what theweight difference is from when it was gas-powered?
Also, your crossmember for your forward motor mount looks like it will be dangerously close to your driveshaft at full compression. I look forward to hearing how it performs after you've put some miles on it!

Bearings aren't "rated" for speed. It's speed vs load vs service life. Pick two.Are you concerned about the input rpm into the black box? Leaf motor is capable of 10,000 rpm, and the bearings in the crawl box are rated for 10,500rpm, but can the planetary hold that?
At 10,000 RPM then it will be going 70+ MPH which is very unlikely for more than a few seconds at a time if ever as that speed would suck the battery down in minutes. It is an experiment nothing is rated for a DIY EV conversion There are other reduction options I can check out in the future if this one gets destroyed. I figure that is still a win because it would mean that I got to drive my own EV Land Cruiser!Are you concerned about the input rpm into the black box?

Motors are the cheaper part. Batteries is where they make the money.Already posted but some more info:
Ford’s 281-HP Electric Crate Motor Costs $3,900 and You Can Buy One Now
Or you can buy two and make a powerful AWD hotrod like Ford has.www.thedrive.com
I posted in the GCC thread. How much will the supporting hardware and batteries cost? The $3900 price for the motor seems reasonable, but will the rest cost $10k more?Motors are the cheaper part. Batteries is where they make the money.
Probably $30K+ for 100 Kw*hrs.I posted in the GCC thread. How much will the supporting hardware and batteries cost? The $3900 price for the motor seems reasonable, but will the rest cost $10k more?
That’s more than I thought. It will be interesting to see what prices do as the technology because more available.Probably $30K+ for 100 Kw*hrs.
Edit: That is using lithium ion 18650s.
That's the new price if you are building your own pack. Used Chevy Volt and Tesla packs are a fair bit cheaper.That’s more than I thought. It will be interesting to see what prices do as the technology because more available.
