Nissan Leaf Motor Bench Test Spinning the Motor - Thunderstruck VCU

[@Tech_1587]

Ben, good simple bench test! There are many things this motor could be used for.

[@patricksellhorn6518]

waoo.. nicebench test.. i like it!

[@TheAnachronist]

I love that you were able to cobble together DC power like you did with just a rectifier and 240VAC with no battery or even a capacitor. This is awesome.

[@turbo2ltr]

Nice work. Brave to use unfiltered rectified AC. I had Leaf VIN 155 back in 2011 and was probably the first that decoded most of the CAN messages. There is a CAN Messages spreadsheet out there that was based off my original spreadsheet I shared with the community. To this day I still get access requests on my original google doc..

[@lolsypussy]

Wow. Does it apply to the leaf gen 3? Where can i find it?

[@AndreR241]

Thank you for this nice presentation. I always find it a bit cute how much you Americans enjoy having a 220 V outlet. Here in Europe you have three-phase AC with 400 V in every apartment or house (3 x 230 V, 120° phase shifted, usually with at least 64 A per phase).

[@ChimeraActual]

Yeah, I'm jelious. We do have 240 to our houses, but it's "1" phase. Would have cost me ~$20,000 to get three phase. Never mind China is building good cheap VFD's.

[@MM2009]

"Here in Europe"? Nonsense. No we are not. Europe is running harmonised 230V single phase 50Hz with 10% deviation so 207-253V- by IEC. Depending on the country protected to 25A in the basement when it comes to apartments so 20A max per apartment . UK urbanised areas usually run at 248V in the socket even though it should be 230V and they only have 63A or 100A single phase (no 3 phase) per household although their grid is so outdated they still have cables remebering Elvis Prestley so 100A per house my ass when it comes to all electric transformation. In some countries old houses e.g. 1950s apartments will have 3phase for electric hobs/ovens but that's not common in modern buildings. Houses come with 3phase in many countries but not all, and depending how old some may share 3phases and max 32A per phase protected on the street so max 25A per house others are 63A or 100A protected. Other countries rich in solar farms are running over 250V as standard which is dangerous for the devices, in some places in France mains sockets are reading continuous 258V in the summer. But it's not a rule because Portugal is 220V and it's a solar Farm rich country as well. East of Europe Russia, Ukraine also 220V . 3 phase been harmonised lately as well to 400V used to it was 280V, 300V, 360V, 380V and 400V 440V depending on the country and how far you were from the local transformer.

[@fredflintstone1428]

Hey Benjamin, I've just watched this video again. It's awesome to see the engineering contained within the Leaf. I bought a used Leaf (one of the first Japanese models 2011) which has been imported to the UK and the car is amazing. My interest in Leaf's is in putting one in a boat. The electric motor conversions that many boat owners install, have really expensive outboards that are tiny compared to the Leaf's. Also the number of spare parts from used Leaf's mean that having spares available is not cost prohibitive. The Thunderstruck kit is awesome.

[@TreDeuce-qw3kv]

Replacing the Diesel auxiliary in my sailboat is also what I would like to do besides putting one in my Miata. 20-years ago we electrified a new 24-ft river launch with off the shelf parts. It was a learning curve and several expensive parts were lost before we managed to get it right. It has been cruising the river for 20-years now with only a battery pack upgrade since.

[@philippaoo]

Hi Ben, Thanks for that video again. I am watching your channel once in a while and that is so relaxing and informative - in contrast to millions of useless videos on YT. Please Go on for very very long! :)

[@markeh1971]

Hi, I like the idea of reusing an old leaf, be it an e+ offering all the parts needed. Indeed there are companies in the Uk now offering this conversion for Land Rovers series I, II, III and defenders using late 40 kWh Leafs as the donors. It’s amazing how little is needed to get it going. Would be good if you let people know how you got on. Take care M.

What a great video. I'm seriously considering using a Leaf drivetrain in my conversion.

[@BenjaminNelsonX]

You gotta get that car home first!

[@kelanbarr9646]

Leaf motors are great if you can get the batteries for a high voltage pack. Plenty of other motors+controllers to buy otherwise.

[@coolfrost6]

Impressive that the inverter accepted that kind of "Dirty DC" voltage, But a good way to illustrate the opperation. Maybe it would be a idea to add a Motor Start Capacitor, just to smoothen out the voltage a bit. But then again it was just for testing and it clearly worked.

[@kschleic9053]

The inverter has a large DC bus capacitor built in for soaking up transients, it is probably doing a fine job of smoothing out the input voltage.

[@PedroDomingos]

My thought was exactly the same! I did know the inverter had input capacitors to average that rectified AC current

[@Tore_Lund]

That bas a Range extenderodes well for people wanting to run a generator as a Range extender, bypassing the onboard Charger completely!

[@franciscoshi1968]

The bus capacitor is very small. You really need to put a bigger capacitor. Another problem is there is nowhere for any regenerated energy to go. So if You Try to use the motor to slow down the bus voltage will go up and you could blow the inverter up.

[@BenjaminNelsonX]

The Thunderstruck VCU allows you to set a maximum regen voltage. That protects against overcharging the batteries from regenerative braking.

[@-allround-]

Love that wooden heatsink on the bridge rectifier !

[@BenjaminNelsonX]

Ha, yeah, well I figured I'd be drawing low current and wood is non-conductive. I mostly wanted to drive a screw through it to keep it from tipping over!

[@SHADOW-bg4mm]

Great video! Was wondering about this motor, i hear it all the time

[@fredflintstone1428]

Brilliant Benjamin.

[@billbitner9142]

Nice! The minimum voltage on the newer (2013-2017?) inverters is 240 volts. I just saw your next video, where you spun the motor using a lower voltage. Mine wouldn't do that, so my guess is there is a software/firmware difference between years. The nissan leaf manuals states the 240 volt low voltage error in one of their diagnostic codes. This means 72, 3.6 volts cells will run this motor, you may want the original 96. For those curious, it is possible to use an arduino or raspberry pi with a CAN module to talk with these motors.

[@billbitner9142]

The motor will also fault if over 400 volts is applied, or you regen too hard and the power supply can't absorb/use the power.

[@BenjaminNelsonX]

Hey Bill, do you have a link to a project or video showing somebody connecting to it over CAN with an Arduino or Pi? I think we'd all love to learn more about it. Also, when you say the motor will fault over 400V, do you mean the motor, the inverter, a Thunderstruck VCU, or some other original component in a Leaf? I am curious because depending on WHICH component it is, that may still mean that the MOTOR or INVERTER will run just fine over 400VDC.

[@billbitner9142]

@@BenjaminNelsonX bbitnerblogs.com/e-miata for seeing the video of me running it via a raspberry pi. www.bbitnerblogs.com/e-miata/archives/04-2020 The high voltage fault is in the inverter, so the stock inverter won't run over 400 volts unless you install openinverter /EVBMW vcu. The bus capacitors are rated for 600 volts, so probably not too much higher than 400 volts,.. ;)

[@chanakamapatuna1456]

Wow....Great work & explanation Sir...!

[@jjsantala]

Nice video series!

[@pierrec1590]

For those of us who do NOT have a 240Vac outlet in our garage, you can configure that bridge as a voltage doubler with the addition of a couple capacitors.

[@Roadstercycle]

Hi Benjamin. Look in the VCU code on a computer, you should see where they set the minimum voltage. You should be able to lower the minimum voltage for testing. That's what we do with the Damien McGuire setup for bench testing the Tesla motors on the bench. Just a thought. Great video by the way.

[@BenjaminNelsonX]

It doesn't appear that the Thunderstruck VCU has any settings in the software for a Minimum Voltage. The only references to voltage at all in the manual are in regards to precharging and regenerative braking.

[@Roadstercycle]

Ben, do you recommend keeping the OEM charger for an EV conversion? If not, is there a better charger you recommend? Thank you so much for posting this! I think my dream of an electric Porsche speedster could be made from the Leaf EV components plus the drivetrain, brake, suspension, etc.. and a Thunderstruck. What a time we live in!

Even after you let the scooter throttle go, the power were still going to the motor. Why? 13:59. In the end, you had to shut it off manually.

Hi Ben, great Chanel, would be interesting if you have to a video of the inverter and charger and how they hook up to a battery and house power charging

[@DJSekuHusky]

TIL the EM57 has remarkably similar output power to the KA24DE found in the Xterra and Frontier/ The revised EM does 148HP and 240Lb/Ft, whereas the KA does 148HP and 156Lb/Ft. The question now becomes does the added mass of batteries make it drive worse, or does the higher torque value still make it quicker?

[@rillip3]

The wagon wheel effect makes it pretty impossible to tell in the video which way is which, given how fast it ramps up under 0 load. I'll take your word for it that it went an opposite way!

[@peterbradley4916]

Great info! This motor maybe suitable for my range rover P38 conversion (which is quite a heavy lump). I was going to fit dual Hyper 9's, but, they won't fit. This Leaf motor would be a lot cheaper.

[@_a.z]

No reservoir capacitor on the DC? Rough DC ain't good! I love the whole bodge though! Great work!

Gotta build a scooter with that motor now. Would be freaking SICK!

[@BenjaminNelsonX]

Well, it's over 100HP. The challenge with a scooter would be to fit a battery pack which is high enough voltage. My Vectrix electric super-scooter runs an AC motor and fits 18 Nissan Leaf cell modules right down the middle for a little less than 150V when charged. Search VECTRIX on this youtube channel for more on that project.

[@grillsandaxlegrease3578]

Love this material! I'm considering a Regenerative braking set-up on a running 62 Pontiac Tempest where the transmission is in the back fed by the engine speed rope drive. Perhaps a 2nd alternator/generator can add to HP keeping up with engine speed.. Just brainstorming now but is it possible to have a helper motor so to speak to the main gasoline block perhaps to offset the takeoff which is where you waste the most gas.

[@marooned-5]

Hello Benjamin! Nice work. it really helped me with my budget ev plans and a simpler and less complexed solution as compared to open source and resolve ev solutions. Could you please tell me it this could work with nissan e power inverter as well? actually i cant find leaf parts here in Pakistan as leaf has just got here but note e power are in significant number and the parts are coming in too. cant find much of the content on e power inverters but thought i should ask you if you ever came across any of those too. Thank you in advance.

Sorry, I am not familiar with e-power inverters.

[@high1voltage1rules]

GREAT VIDEO BUDDY” “BUT” You definitely need to make your wires safe! Those croc connectors you have on you bridge rectifier are only rated each at best 3Amps. And when you have full spun up this AC motor there will be a very big rush of current easy pulling 8kw or more! and your bridge rectifier will be getting warm or hot ( needs a heat sink! For constant use!)and to be Honest the dc from the Ac will be noisy and could do with smoothing! Using capacitors and a couple of inductors. There will be a lot of inductance noise through your setup as you have thin wires and investors don’t like this! If you had this going through an OSCILLOSCOPE you would see the noise coming through on the graph! This setup you have could damage your controller for the circuit. Your setup works well. But my friend you seriously need to use the correct wires and connectors being all the same!😉👍 Best of luck! Please be safe. Great video 👍👍👍👍👍THUMBS UP👍👍👍👍👍

[@neliosamch3195]

Ben, Can you connect in serie the motorcycle batteries for the 300 volts? This is very interesting for those who are waiting for a cheaper alternative to convert their diesel engine sailboat to an electric drive motor. My GTIL are working very good. The limiters do not let the inverter export excess of power, everything goes into 16S 280ah for night time and the bill is coming down a lot.

Hi Ben , new subscriber, love your videos, I dont see much on social media about using the charger from the Leaf. Doing a marine conversion and would like to use the complete Leaf system ( batteries, motor, inverter, and charger. Any Thoughts, thanks Tim.

[@BenjaminNelsonX]

Sounds like a great project! I do NOT have any experience using the Leaf charger, so I don't have any advice on that. I DO know a guy who gutted a Leaf, and used the ENTIRE motor/charger/battery, etc. etc. in a cool-looking old kit car. It seemed to work well for him, but he did get frustrated at some points because of the wiring. If you want to gut an entire Leaf, make sure to properly label EVERY wire connector so that you can more easily reuse all the parts in another project.

[@SheepShearerMike]

Do to see you are now mentally in a place you can carry on with this project Ben. Have you solved how to drive the PTO? I would think you could use the standard gearbox with double clutch, most of the time leave it in gear then use the forward and reverse switch so you don't need to clutch. Then if you do need the PTO, you will have to use the clutch as before. Also, are you going for the electric hydraulic pump?

[@BenjaminNelsonX]

Driving the hydraulic pump is still a bit of a puzzle. If the Leaf motor had a tail-shaft, I'd just attach the stock pump there. Electric pumps draw a lot of current, and I'd need a really good-sized DC/DC converter to run that. At this point, the easiest route to go would be to use a PTO-powered hydraulic pump. I think I'm just going to get all the drive system worked out first, and THEN worry about the hydraulics.

[@BenjaminNelsonX]

I intend to re-use the original tractor transmission with the double-clutch.

[@vitaliyyavtukhovskyi5947]

Hi Ben. Why is the motor spinning at a constant speed even after the throttle returns to 0 position?? I did not expect that one... And then to stop the motor you have to turn off the power supply? Again, why doesn't it just come to a stop when throttle is released? Thanks in advance!

[@BenjaminNelsonX]

Hi Vitaliy, I still needed to fine tune the throttle settings in the software.

There's plenty of these motors available through salvage yards. You'll need some way to control the motor, which can be the Thunderstruck VCU.

[@portugal1969]

Do you think it could be run on a generator

[@2Bikemad]

Why does the motor stay running after the throttle has been fully released? The motor is obviously still being powered as the rpm was gradually increasing until you eventually switched the power off. It's as if you're demonstrating a perpetual motion machine that runs on its own once you start it spinning, but without the obligatory light bulbs and the disconnected power plug ;)

[@BenjaminNelsonX]

Looks like I need to calibrate the throttle.

[@neliosamch3195]

There isn't a flywheel or capacitors to keep it running. It must be the inertia of the motor. If the motor generate some energy it will go back to the battery. A clamp meter verify if that is possible.

[@BenjaminNelsonX]

@@neliosamch3195 Keep in mind that in this video, the motor isn't even hooked up to a battery, therefore there's no place to send the energy to perform regenerative braking.

So you get approx 338V pulsed DC (ON/OFF 120 times per sec) out of that rectifier, dangerous to play with (especially out of a 50A plug) but pretty close to the expected battery voltage. Just add smoothing capacitors if you draw more amps and the inverter gets unhappy with the pulsed input.

[@franciscoshi1968]

@@Tore_Lund you can but it will not be very effecient. The problem is that a bridge rectifier will only conduct when the input voltage is higher than the battery voltage. So that means say your battery is 300v. So when the sine wave from your inverter is below 300v no current flows when it goes above 300v then current flows into the battery but that is only for a very short percentage if the input wave. So if you have a generator you will find the voltage will sag and you will only get a fraction of the power capacity of the generator. To fix this you need to either put a very large inductor between the bridge rectifier output and the battery or you need to put a power factor corrected front end (ie a charger)

[@fredflintstone1428]

If I used the original Nissan Leaf battery along with the inverter and motor in a boat application, could I actually put charge in via the car charger while it was running? I could provide the Leaf's battery with charge from a 10kW solar panel deck via an inverter provides 240V AC (to simulate the car being plugged in at home).

[@racingfortheson]

How many amps would that motor pull when running the full car down the road?

[@BenjaminNelsonX]

Depends how hard the car is working. The motor will pull much higher current accelerating or going up a big hill than it will going downhill with the wind at your back. Looks like the Leaf e+ has a peak power of about 100kW. At 360V, that's around 280 amps. Just typical driving is going to be much lower than that.

[@tstlavceoceo7066]

I have a 2wheel drive pathfinder and thinking of incorporation a 4wd front diff and driveshaft. Do you think this hybrid setup could work with reasonable benefits.

[@BenjaminNelsonX]

A transfer case would certainly be one way to add an electric motor into a gas vehicle. "Reasonable benefits" depends exactly on what you expect. Seems like a lot of work if you are just going to get a little better fuel economy. On the other hand, if it's a plug-in hybrid, and you can drive the vehicle completely on electric for some reasonable distance, that sounds pretty good. I think that the most efficient way to build a DIY Hybrid would probably be to have a transverse-mount dedicated gas engine directly on one axle, and a dedicated EV system driving the other axle.

[@surplusstock8778]

@@BenjaminNelsonX The boat isnt equipped with sails but as its 72ft it has a large surface area for solar.I bought the boat without engines for a giveaway price.I wanted to retrofit my boat similar to the new silent 60.They use 2*50kw motors,201kw battery pack and 15Kwp of solar.At 7 knots in sunny conditions it will run off solar alone with a diesel generator for backup in bad weather.

How many version of motors are there ? which years should I be looking for a easy conversion ? ? Thank you

[@paulmoretto1224]

So how do you think the leaf motor + VCU compares to commercial offerings like the hyper9/warp9 type motors. More specifically, those in the DIY community looking to do EV swaps.

[@BenjaminNelsonX]

I couldn't really say, as I haven't used a Warp9. I guess a person would simply have to compare the specs on what they are looking for. One nice thing about the Leaf is that a whole Motor/Inverter/Gearbox can be had very inexpensively from a salvage yard. The Leaf setup is a good one, but in some ways it's LESS DIY friendly. For example, There are already plenty of bell housing adapters available for more standard motors like a Warp 9. Also, the shaft is splined, instead of straight with a keyway, so that's one more step for creating an adapter or coupler. Probably the best way of reusing the Leaf setup with MINIMAL custom fabrication is to keep it with the original gearbox, and install the whole thing in the back of a rear-wheel drive car. Then just use custom half-shafts from the stock Leaf gearbox to the wheels.

[@kschleic9053]

A leaf motor+controller is going to be significantly less expensive, and will have more power than a hyper9/warp9 setup. However, to get that power a leaf motor needs a significantly higher voltage then the hyper9/warp9 operate at, meaning the minimum pack size is larger. If I had to guess, the overall cost will be similar, but with a leaf setup more of your $ will be going towards batteries (range).

@@kschleic9053 I am guessing the hyper9/warp9 is going to be more diy friendly as well.

First to admit I know little about EV motors, still, I have some questions. You said it's a three phase motor. Is it a permanent magnet three phase induction motor? If so why can't you run it off a VFD? Seems simpler than turning 2 ph into DC, then back to 3 ph as long as it's not running around on the street. How many poles? Hp? Frequency range? AC Voltage? RPM? Why am I'm asking? I wonder if I can adapt it to my lathe or Bridgeport. That would be fun!

[@BenjaminNelsonX]

It is a permanent magnet AC motor and the inverter here IS a Variable Frequency Drive! I simply ran this off of AC, because I didn't have a high enough voltage battery pack at the time that I shot this video. I got the idea because a friend of mine has plenty of experience with industrial motor controllers. A number of years back, he converted a Dodge Neon to electric, using off-the-shelf industrial parts. The variable frequency drive that he used for the car could run off AC or DC. He essentially just mounted it in the car and ran it off batteries. kzbin.info/aero/PL47D94695998158F6

[@2point2]

Did you ground the 12volt (-) to the case of the inverter\motor?

[@BenjaminNelsonX]

I'd have to double-check the instructions that came with the Thunderstruck VCU. There's a number of wires on the harness, but most of them go to either 12V+ or 12V-ground, so I'm pretty sure one of the wires on there somewhere is just straight to the frame/body/casting of the motor and connected equipment.

[@elektrokinesis4150]

you really need some big capacitors on that ac feed

[@BenjaminNelsonX]

The inverter already has plenty of big capacitors inside it.

About how much torque is this thing capable of in a car?

[@neliosamch3195]

80 kW (107 hp) and 280 N⋅m (207 ft⋅lb)

[@jimchance5006]

@@neliosamch3195 that number is through the stock 8:1 gearbox correct? Is that the number at the "crank" of the motor, or at the wheels? I'm planning on coupling one of these to my stock gearbox whose transaxle x first gear is 12:1. I'm wondering about how fast that will be. (car weighs 2200 lbs with stock engine)

[@neliosamch3195]

@@jimchance5006 yes, at the gearbox. At the wheels is variable depending of sizes and wears of the tires and transaxle ratios. The term refers to the gears in the truck's differential, which is a mechanical device that links the rear axle to the driveshaft and then the engine. Technically, the number should be expressed as a ratio, such as 3.55:1, But that gear ratio would most commonly be referred to as "3.55" or simply "three fifty-five." A numerically higher axle ratio provides a mechanical advantage to send more of the engine's available torque to the tires.

It's an EM57, that's the later motor.

[@FrankGraffagnino]

where do you hook up the wires for the "motor temperature sensor"? My EM57 motor didn't come with the black wire harness unfortunately so I will need to make those connections manually :( any ideas? I'm not even sure where that sensor is located.
