your a bloody genius damien. I hope all is well health wise with you now. Here i go to every website possible trying to buy a cheap prius inverter!!
Great job. We've been doing this too, on the other side of the pond. We have the IPM module operating as a 8S and 16S charger for our EV packs. We will also be using the other parts from the inverter/converter for 2-3 more applications (235V DC charger, spot-welder with some of the bus bars & IGBTs, and perhaps mating an EGS002 controller on the 3-phase IGBT modules for a huge inverter). Loads of fun hacking.
And here I thought the Prius was completely useless! lol. Great stuff, especially if you have an EV you plan to upgrade to AC later on but lack the funds. Liked how the cat was completely unimpressed by all the motor running on the bench.
Yeah my cats don't like the noisy bits:) I think these Prius inverters can be very useful.
G'day Damien, your timing is perfect! I've been collecting Prius bits to convert my Suzuki Jimny to EV. So far I have the Inverter/Converter, battery cables (from traction battery to inverter), fuse/safety pull, contacters, and precharge relay/resistor. In fact, if I do this again, I would just buy a scrapped/wrecked Prius to harvest all the bits and pieces needed.
I'll be consulting with the Minister of Finance to support you on Patreon.
I'm looking forward to future hacking of the inverter, and sourcing an AC motor for the future eJimny.
Stay well and thank you for your generous sharing of your expertise and knowledge.
My pleaseure
Minister of Finance has approved Patreon support!
hi, Wow, your video was posted on my birthday last year! (at which time I was recovering from being hit by a pickup truck while riding my bicycle! ugh..)
anyway just this month Ive caught the prius bug and got my momma to buy one, and then I bought one (cheap) that had been in a minor front end collision that I am reviving (both are gen 2 mind you!)
so I have been out at this Awesome local junkyard several times this week and have been staring inverters such as these in the face repeatedly...
everyone snips the wires and pulls the inverter to get to the brake accumulator hidden behind it (a part that frequently goes bad limiting the longevity of these great cars!)
anyway yeah its inverter city out there!!!
anyway im interested in updates, I am daydreaming about a project to run a 48volt golf cart off one Huge 1.2 volt NI-FE battery cell (something like 1-2kwh)
these batteries are known to last multiple decades even when abused or neglected and that sure beats the pants off most other battery chemistries, especially for an infrequently used neighborhood runabout... thing.
I wonder if a prius inverter could be used for this project... I was thinking about a solar panel roof trickle charger, and maybe some 12 volt accessories (stereo maybe?)
lots of voltage conversions would be needed 1.2v to 48 volt with drivetrain current handling ability, solar panel voltage back down to 1.6 volts for charging, and then 1.2 to 12 volt for accessories..... errr and maybe 48 volts to 1.6 volts for regen braking....
wow that's a mouthful!
anyway anyone who may be tinkering with these please lets put our heads together maybe start a forum thread...
if I go back to the junkyard im gonna grab all the inverters and stash them somewhere safe, like in the back of a prius unlikely to be crushed anytime soon!!!
people literally have just snipped the wires and tossed the poor things in the mud!
Another great video Damien, I will send you over some pictures of the Aventador project to your e-mail to show you what we’re up to and hope that I can pick your brains at some point. Cheers Scott.
Sala Motorsport Intriguing, what are you up to doing with an Aventador? If it's an aventador ev I can see v12 people crying all the way from here.
Yes an Aventador with two performance Tesla motors, front and rear.
Sala Motorsport Sounds great, the Aventador is one of my favorite cars that I won't ever be able to afford (especially the sv, charmed me when I first saw it). Maybe a blown engine wrecked one to go full tavarish on and try to restore it someday... I should stop saddening myself and keep typing. I want to put a tesla motor in something like a "newer" 2012-ish BMW (4 cylinder not well taken care of ones are plentiful here for a nice relatively affordable shell), to have a nice hopefully economical and perhaps somewhat fast daily driver car in a country where displacement based taxing won't allow me to afford an enjoyable car. Those damn tesla motors are hard to come by and are expensive as well, for broke me atleast. What happened to the engine in the Aventador though? I can't imagine just removing that masterpiece to go electric. Sure it's a waste of gas/km, but it's still a work of art. Either way, I've subscribed to you in hopes of seeing more, as this kind of thing is right up my alley (I'm watching Damien after all) Seeing Damien involved with the build of a custom Aventador would surely be interesting. Going from hacking whatever parts he can find in a wreckers yard to that would be quite the change from the ordinary. As I said before I can already hear the purists crying. Anyway, thanks for replying and do excuse my rather lengthy response, I may have gotten carried away. Looking forward to hearing more about this project.
Hi renyn21,
I have bought all the parts and i'm building from scratch, so i never had an engine or drive train. I have the chassis and suspension and 90% of the body and i'm just going to go from there. I'm actually a composites engineer and car designer so i'm in the process of taking a mould from the monocoque and jigs of the sub frames so that if this all works out on the Aventador test bed i will build more cars with my own design body. Fingers crossed. Scott
damian thanks , for the good work we are waiting for
thank you:)
you are amazing!
Great shtuff bai!
This seems pretty cool! Could someone tell me if this could run an industrial AC motor ? I've got 2 that I want to use in a car hopefully.
Excellent work. Could this charge and dc/dc convert on a 360v leaf pack?
oh yes :)
@@Evbmw 😀👍
sorry just posted above then saw this. Very very interested.
So this Buck Boost module, which I'm assuming does at least 100A, could be really handy for adding any voltage back as extra capacity on older low capacity EV's. So many fun possibilities!
Damien, my Zivan charger appears to have quit completely. I was charging my electric truck containing 3 strings of Leaf cells in parallel with a max pack voltage of 131. I am hoping to be able to use the Prius inverter for charging. However, I am limited to either 120V or 220V single phase AC to supply the power. Since the Prius motors are 3 phase backfeeding the battery, I am not sure how to connect to make the system work. Could you address that when you run through your testing?
Thanks for uncovering the possibilities with the Prius salvage parts.
Working on it:)
Hey Damien, Do you think that buck boost thing can be used as a high power 14v buck converter for something like audio amplifiers? 400 amps on 14v would be helpful, stacking normal dc to dc converters to compensate for the missing alternator would be expensive as hell just to keep the batteries in an EV audio install alive. I suppose one could use it to go from 300/400 volts from the traction battery to 100v that an amp uses internally, bypasing the voltage boost inside the amp and increasing efficiency, but I don't know how that might affect the sound quality, and of course that would mean just butchering a very expensive amplifier (one that would require such power I mean) giving an audio amplifier 400 amps with 14v is a hell of a lot less efficient when the higher voltage it actually needs is available in the car. Once again, that prius box could prove extremely helpful in saving alot of money for hobbyists.
If I understand correctly, providing a PWM signal to one of the phases it can drive a DC motor? For AC will it require 3 PWM signals for an AC motor? I've just used an off the shelf controller for my motorcycle but keen to learn how it works and hopefully do a car next using scrap yard parts.
I want to know is you can turn a non phev Prius into a phev using the inverter and charge the battery
I would like to put the motor and controller and even battery in to a older vehicle! How difficult is it to get it working without all the peripherals?
love the cat
How to know the capabilities of this inverter circuit? Amp and volts wise. While MG2 here is 60kW in Prius, it is 168 kW in LS600h ... I would say all Toyota's inverters are the same 😊😊.
Page 50-58 of this 95 page report has details of the inverter/converter. Apologies if this is TMI. But for those into reverse engineering and re-purposing, this is a gold mine. You can also google prius inverter teardown, there is a detail wrtie up on it. Cheers. www.osti.gov/servlets/purl/890029
So if this unit has MG1 and MG2 output are you going to link it to the Lexus drivetrain that you were testing a while ago?
given that it can take 3 phase ac and charge batteries up to 400v dc. do you think that it would be possible to give EV's like the nissan leaf 2011 24kwh a boost in charging off the 3 phase enabled or even single phase outlets. Currently my leaf can only utilise 3.6kw off the posts which could give up to 22kw or 7kw. There was a chap who sort of did this using Brusa chargers mounted underslung at the rear of the car but they were thousands whereas these as you point out are merely hundred(s) of pounds.
Also there is a french chap called Gilbert Trouve (aka planetaire on priuschat forum) who did amazing things with his Prius. He would definitely be interested if you got the paralleling of the inverters working because the limitation of turning a 2nd gen Prius into a good full EV is the 20ish Kw limit of the inverter.
What types a motor Prius have. PMAC or BLDC. Motor ???
ipm
@@Evbmw thanks you are my hero ... Спасибо
Is there a possibility to use the boost converter to drive the motor at higher voltage? Toyota is using this circuit to drive the motors at 650 volts..
And, is there a benefit of doing so?
HI, a frien of mine is currently selling a prius motor with inverter and hacked controller plus contractors, pedal-pot for 4000 EUR - he can even set it to your needs. you only need batteries and to mount it in the vehicle. I am bulding my own hybrid sistem with a hacked ampera controller - but his offer is quite decent, i think.
I will be pleased if you can fix som interface card so we can skip the Ev speed limit (40km/h)and make a real plugin of the Prius/highlander drive unit 😄,
so i can buy batteries and connect
regards 👍
Rickard Björling the true limitation is the mechanical system that Toyota runs. You can't increase the wheel speed unless you revved the engine as the MG1 speed is maxing out.
this is what has always bothered me. The Toyota Prius is basically the perfect power plant for just about any car audio installation or any home generation. You can also use it to drive around if you'd like.
the fact that you can use natural gas or compressed CNG with this motor makes it even more efficient and cheap to operate. if they offered a diesel option that would be basically the killer application of this motor since not only could you use it with the various diesel fuels including green diesel fuels that actually work quite well like biodiesels you could also use it on propane natural gas CNG Etc.
the other thing that's a real bonus using a Prius power plant for a generator at home is that you also have a water heater and if you use a Evans coolant on the coolant Loop you can also run the coolant at around 350 degrees and again increase efficiency.
with the introduction of hydrogen into the combustion process, you get a very clean burning Engine with that has almost no performance penalty for introducing the hydrogen or fuel economy loss. You simply get a very clean burning engine.
quite frankly the Toyota Prius is one of the best power plants ever devised. adding a low pressure turbo would only increase the volume metric efficiency of the motor and increase its performance and its gas mileage strangely as it provides a source of induction that overcomes the friction and the restrictions of pushing the air through the piping.
I'm keeping this explanation really basic for the people who are not familiar with how engines internally work or Kmart engine heads.
also if you have a small Toyota Prius motor and decided to put it on the back of your truck you also have the perfect car audio alternator. a large bonus to this is that you are now able to use the Brazilian amps that run on an extremely high voltage and can put out 160000 watts of power the bigger bonus to this is that amps like this that produces kind of power cost a little less than $800 to purchase and you already have your high voltage battery Bank ready to go.
technically you don't need a catalytic converter when you're using it as a home generator so you're also eliminating that restriction as well and you can tune the engine for absolute efficiency and with the introduction hydrogen you don't actually need the catalytic converter anymore.
I figure most people will simply hook their cars up to their home natural gas and just use it that way as it basically is an unlimited supply of fuel coming directly to your home.
most amazing thing about the hybrid Prius power plant is that imagine you having a very large RV and it is now able to not only go up Extreme Hills but with ease. using a larger battery pack you can actually add an additional motor to the rear axles and then not only do you have four wheel drive you also have a very large traction motor in the back that can push you up any steep grade with ease and with the hell of a lot of torque on tap.
the only thing that would make it even more efficient is basically to use a TDI Diesel with all the Eco mods to get the most miles per gallon out of the engine and power at the same time. Toyota already make some fantastic diesel motors and in that sense you're really on your way to basically the most efficient and most perfect power plant ever conceived.
3 years later, and I guess I will be one of the first to use these in a high power SPL style setups as its on my Bucket list.
The Toyota Prius has got to the point where you can buy an entire car for less then $2000 dollars running and driving.
Only thing is, I will be doing this outside of the USA in my new location. Might be Japan.
Damien, as this has sparked my interest, I've been doing as much reading as I can find. I'm sure you'll have probably already stumbled upon this article about paralleling the IGBTs www.nkirkby.net/derptruck-part-3-bottleneck-of-inadequate-performance-and-the-embrace-of-greater-delights/ and the 400amp overcurrent protection, maybe you have a trick up your sleeve.
I like it
