Homemade Electric Buggy, Ep 3: Powertrain - LiFePo4, ME1616

Homemade Electric Buggy, Ep 3: Powertrain - LiFePo4, ME1616
In this video I fit the powertrain components into the chassis of my homemade electric buggy. This buggy will be powered by a 55 kWp (72 hp) ME1616 motor from Motenergy, and a 14 kWh LiFePO4 battery pack. LiFePo4 cells are much safer than lithium ion and lithium polymer cells, and last much longer, up to 2000 cycles. Check out my blog for more details about the parts that I used and how they were installed:

[@nguyentri1996]

Im looking to build one of these as my senior design project, any advice?

[@robert5]

I am interested to know the details on how/when that clutch pack activates. Does the rear end simply free wheel until the input shaft starts turning activating the pump then the clutch pack? Reason is I would like to use this rear end in a buggy with a gas motor. If I can activate the internal clutches as needed then I don't have to run a clutch on the gas motor. - Doing some research I see the later 2013 CR-V uses an electronic activated clutch. Wonder if that would work and how harsh the clutch engagement would be. - Doing searches there is little if any info about this. Read on a forum post the 1st gen CR-V diff ratio is over 4 but can not confirm. I am also wondering if there could be a planetary reverse setup built to take the place of the pump and clutch pack. - That would result in a complete tough differential package for a gas engine buggy. I need to find out more about these CR-V diffs and how the different generations are built. - If any one knows where the gear ratio data is for each generation please reply and let me know.

[@Coolvak]

What a perfect use of gearbox also best mount for power motor , Best weight distribution. It will give you great traction and best control on your Buggy. At the end of video " what a power pack " One little suggestion , please use best sefty gear . She's going to fly on Roads🛫

[@michaeldavis4351]

Wicked!

[@nikolaichovkowsky]

Will the differential still function if the clutch is locked? or is it just being used as a means of power delivery to the wheels? Awesome project :D

[@JamesBiggar]

Thanks. It's the only way for the differential to function - if the clutch isn't pinned, the diff has a slip. I've detailed why in the video description.

[@Skiridr22]

That’s a huge controller

[@TheDavidneal48]

This is awesome, have you had any issues programming the Kelly controller? I am looking at getting one for my build with the same ME1616 but am told the controller does not come pre programmed.

[@JamesBiggar]

You can request it to be. But it's not difficult. Just follow the instructions in the Kelly manual to perform the angle identification procedure when first hooking things up (ie syncing the motor with the controller). I've never had a problem with a Kelly controller. Curtis controllers are also a good option. Just be sure to get the RIGHT controller, for sine/cosine signal, not hall.

[@HisnameisRich]

Were you not concerned by the change in force direction on the differential? (from the top rather than from the front) I am looking to do a similar project to this one and I have a good quality car limited slip diff that I want to use but was concerned about the direction of the torque.

[@JamesBiggar]

No. I can't say it's better or worse than what others have done, just that it's a simple way to achieve limited slip instead of doing what most builders do and mount a sprocket to a solid shaft and put up with the understeering at low speed. I've had 0 problems with it, just have to make sure everything lines up as close to perfect as possible because any bit of misalignment will increase wear and tear on the chain and sprocket, and it'll noisy. The shaft for this diff is supported securely with standard radial ball bearings which are designed specifically to withstand radial forces like what I'm putting it through - it's no different than the timing chain and sprockets in an engine, same principle. There's another way to get the same result but with more work, basically involves removing the gears from a small diff, replacing the ring gear with a sprocket and building a custom housing for the gears to keep them lubricated while keeping the sprocket exposed. There are a few examples on KZbin. It's more compact and I might try it later with a transmission. I've got a few mods in mind, but again, I've had no problems with it as it is.

[@HisnameisRich]

[@JamesBiggar]

Thanks! Check out Brian's kart at his XS Motorworks channel. I borrowed his idea for the diff. I think he's using the smaller ME1507 motor. I don't know of any other electric crosskart/buggies. But check out the Ghost EV TV channel too. He's building a small car using two of these motors. He was peeling the tires with just one.

If you like ICE engines look at co2 neutral fuels which is a good alternative to electric. Scientist grow algae which produce all kinds of carbon based fuels like diesel petrol and Kerosin.

[@vladomie]

An interesting location for the disc rotor 💿 What's up with that?

[@JamesBiggar]

CR-V hubs are built for drum brakes - I don't want drum brakes. This isn't much different than having one rotor on a solid axle like in other smaller karts or racing quads, it's just turned 90° and attached to the diff drive shaft. Brake rotors can't be attached to cv axles easily, not these ones anyway. One large rotor and dual calipers in a drier location will perform better than drum brakes, and they won't be in the way when it comes time to change the hub bearings. Nor will I have to remove the wheels to change the brake pads.

[@Todd_Gerhardt]

@@JamesBiggar plus u get more mechanical leverage being in front of the diff and not at the wheels

[@lasaucissemasquee4421]

Great video. Could you please explain us why you decided on LiFePO4 cells ?

[@JamesBiggar]

Thanks. Simple - they're a good balance between safety and energy density. If I run into a tree on the trail, crush the chassis and damage the battery, I don't have to worry about being trapped in a fiery inferno because LiFePo4 cells won't ignite like Li-ion and cause a runaway explosion. You could punch a screwdriver straight through one of these cells and it will just expand and maybe smoke a little, but no fire. These cells from batteryhookup.com are also sold at the best price that I've seen anywhere, and they're underrated. Most people are finding these actually have 5500-5700 mah capacity instead of 5000, but they rated them at an even 5000 just to be safe because their manufacturer says there's a +/-5% margin of error.

[@SniperSnake50BMG]

Mr James have you considered the idea of using LTO cells? They have a little bit lower energy density but the power density is INSANE. you can abuse them and even fast charge them as much as you can. I have a little pack (2.4kw) for my electric motorcycle and although it's range is lower compared to LFP or NMC always a charge of 15 or 20 mins is enough for calling it a day.

[@JamesBiggar]

Yes. But the price needs to come down A LOT before I'm willing to go broke to build a large pack with them. I can barely afford LiFePo4 as it is lol

[@kmuralikrishna1582]

Really appreciate.. waiting for your next video... But question is why such a high power motor (55kw) is required there Can't we use 3 to 5 kw motor...?

[@JamesBiggar]

Because this is not a boring commuter machine that putts along at a snail's pace on city streets. This is an off road race machine. Think of it this way - if you want to lift a heavy weight, what do you need? Muscle. If you want to lift a heavier weight, you'll need even more muscle. It's the same with motor vehicles or anything in life - you need the right force to do the work effectively. The more weight you want to move in your vehicle, the more power you need to move it or you're not going anywhere fast, if at all. 3-5kW is only ~6 hp at the most, that's barely enough for a 100 lb e-bike to climb steep hills. This machine will weigh between 750-800 lbs. 6 hp would yield a very disappointing power to weight ratio of only 0.008hp/lb. A gutless Prius has a ratio of 0.04hp/lb. It would be close to half the weight of a Prius, but only 1/4 of the power. It might as well be operated with pedals. It would feel like it's towing a bus on flat roads and it definitely won't climb any hills. With 55 kW, it has a similar power to weight ratio (0.1hp/lb) as a Tesla EV, or a stock Porsche 911. There won't be any stopping it unless it hits an immovable object. Power to weight ratio is what matters if you want to have fun with your vehicle.

[@JamesBiggar]

To answer your other question, 55 kW is the motor's peak power rating, which it can sustain for ~10 seconds. Continuous power rating is 24 kW, which it can sustain indefinitely (hence continuous vs peak power). Like an internal combustion engine, a motor can't be operated at full power indefinitely or it will overheat catastrophically. There's always a continuous and peak power rating. The controller is rated for 240 amps continuous (not 200) and 600 amps peak, ie: ~ 23 kW cont and 57.6 kW peak which it can sustain for ~ 30 seconds. This is why I chose this controller for this motor. The specs are close to matching, and the controller can be programmed to use slightly less power to protect the motor and battery from overcurrent use, which is its job. The battery has a capacity of ~12 kWh...not a power of 12 kW. You're confusing terminology here. Kilowatt and kilowatt hours are related, but different. Kw is a measure of power or force, kWh is a measure of energy, energy storage, or work. Related, but different. The cells used are rated for 5 amp hours of capacity, and can deliver 15 amps of current continuously to the motor, or 50 amps peak for 10 seconds. Connecting cells in series increases voltage, connecting in parallel increases current discharge and capacity. The battery will be arranged in a 24P30S configuration, meaning 24 cells will be connected in parallel to form one large cell to increase the storage capacity from 5 Ah to 100 Ah, and will increase the current discharge capability from 15 amps cont and 50 amps peak to 360 amps cont and 1200 amps peak, and there will be 30 groups of these large cells connected in series to increase the nominal voltage from 3.2 to 96V. Ergo, the 12 kWh battery will be capable of delivering 96 x 360 = 34.5 kW of continuous power to the motor and 115 kW peak. As mentioned previously, the controller can be programmed to limit this power so that the motor doesn't draw more current than it can safely handle. The controller can be tuned all the way down to 1 kW if needed, though that would obviously be a huge waste of power and energy. But it's better to slightly oversize equipment like the controller and battery by at least 10-20% more than the power of the motor and use the controller program to limit current to a safe level so that nothing overheats and efficiency is maximized.

@@JamesBiggar Thank you

@@JamesBiggar Really appreciates your explanation. One last question is, it seems it's an automatic gearbox, what if you use a manual gearbox. which one is better in terms of the load instead of speed.?

That's a differential, not a gearbox or transmission - all differentials work automatically except manual lock differentials. Ev's don't require transmissions, they produce more than enough torque for accelerating, unlike an ICEV. All ICEV's require transmissions of some kind.

[@JamesBiggar]

Independent suspension. If you mean shock design, ie spring rate, travel, etc., that's going to depend on a few factors like sprung and unsprung weight, control arm length, angles, etc. Search out a spring rate calculator on google and use that for designing or consult a suspension specialist when you buy your shocks - they'll set you up with the right specs to suit your cart.

A video will be uploaded covering the battery build, AFTER painting. No sense building the battery if I no where to install it yet. Patience is a virtue.

[@DaveDuzzit]

How's the luck so far with those battery hookup cells? I ordered 144 of them for a 5p24s pack for a 72v 8000w electric bike. The pack is complete on a 200A Daly BMS, and the bikes almost finished.

[@Todd_Gerhardt]

I'm curious too as I've been needing to make a pack for my drift cart. What do u use to make yours? (Tools, battery holders, ect)?

[@DaveDuzzit]

@@Todd_Gerhardt I use a 1200A spot welder with a pen probe at nearly max setting to work for .20mm pure nickel strip and 32650 cell holders (That is required for high amp draw from the pack, sometimes even 2 layers thick). Once the strips connect the cells it still is a somewhat flexible pack, so I wrap it with polyimide heat tape before cutting a large shrink wrap for the pack. Go for a Daly BMS, they are currently on Amazon at a good price.

[@JamesBiggar]

Haven't started the battery yet, just finished building a brake to bend the aluminum body panels. Once I get everything done as far as the chassis mounts and it's ready for paint, then I'll shift focus to the battery. This will be my first time using these cells, but they have a good reputation. I'm using a Daly BMS as well, 20-24P30S configuration (haven't settled on capacity yet). Using a 5000W spot welder to weld 2 layers of .2x15mm nickel strips to the cells and then solder them to thicker copper busbars running between the cells on each end of the parallel groups to carry the final current through each series connection. Kind of like what's done with cell level fusing, but without the fusing. I considered doing that as well, but figured these are a lot safer than Tesla's li-ion 18650's so if one of the cells short later I'm not too worried about the entire pack catching fire on me. It could be a really dumb decision, too lol. My luck isn't the greatest...

[@DaveDuzzit]

@@JamesBiggar I also just noticed yours have the white ring insulator up on the positive of the battery, mine came with cardboard brown. I'm hoping they didn't re-wrap some k2 cells or something for mine or something. I'll be following along to see how your cells end up!

[@JamesBiggar]

Highly unlikely, they're manufactured specifically for Batteryhookup. They do sell K2 cells, too, along with Headway, Topband, and others, but not with their company name printed on the side of them. They take a lot of pride in their family owned business and have invested a lot of time and $ into their cells and nickel fuse sheets, and make a point to call out scams when they see them (I've been following and shopping through them for a couple of years). I recommend searching out other battery builds on KZbin using these cells, or other cells that they've supplied. They have an excellent reputation.

What is the highest speed of this motor please tell me

[@JamesBiggar]

Depends on gearing, tire size, weight, etc. Motor specs alone don't determine top speed. With 22" tires and 5:1 gearing I'll achieve around 120 km/h with this vehicle. With 3:1 gearing a person could reach 160 km/h, and so on. Power is a function of speed and torque, which also means that more speed = less torque, more torque = less speed. There's a compromise, so you need to gear it for the task. Asking what the rpm and torque is would be a better question. See the description for links.

[@Reman1975]

I'd probably have just degreased the clutch pack and reassembled it with a thin coating of JB Weld on the face of each plate.
