Power generator, using MG1 + MG2 Prius 1 or 2
Power generator, using MG1 + MG2 Prius 1 or 2
Hello,
I propose to the attention of all those interested and approved, the production of electricity using MG1 + MG2 from Toyota Prius 1 or 2.
The idea came to me trying to produce electricity using a PMG motor / generator driven by wind, water or ultimately a heat engine.
I was wondering if I could use the gearbox and the Prius converter to achieve my goal.
I understand that the Prius converter has several functions:
1. It has 2 inverters, the strongest capable of about 400A
Uses 1200 V IGBTs
2. It has a buck converter (seen from the inverter to the battery)
3. Does it have a DC / DC HV -> 12V converter that runs independently up to ~ 150V, up to 300V?
4. It has a third auxiliary inverter which also operates independently but is not yet clear
I want to use it, using a 32-pin plug with an external adapter.
Now I am asking the specialists if it is possible to adapt a new external module or reprogram one of the two that has already been done, such as: openinverter.org Brain Board Rev 3 - community edition
Toyota Prius ™ Gen2 inverter controller - community edition.
The intention is for the converter to charge the HV battery or a 12 v battery but with a large capacity of 220-500A or to produce direct three-phase or single-phase AC current, so that it can be used for home and home use.
I am waiting for your answers in this way!

Re: Power generator, using MG1 + MG2 Prius 1 or 2
Your assumptions about the inverter are correct.
So you want to attach a gen2 gearbox to the inverter. The gearbox is basically always in regen mode and is turned by some power source like a wind turbine. That generates some voltage on the DC bus, say 300V, that you then want to feed into a battery. Forget 12V, the translation ratio is too bad. Maybe 60V. Then to this battery you connect some retail inverter that makes 3-phase or 1-phase AC. That last part is not openinverter driven.
You'd need 2x Toyota Prius ™ Gen2 inverter controller because you want to use two machines. I'd suggest to not use MG1 to start out with. Then you just need one controller.
You can also buy two controllers and then use MG1 inverter to generate 1-phase output. Either directly from the power generated by MG2 or via the boost converter from your battery. 3-phase would also be possible but is not supported by software yet.

An extraordinary thing, your recommendation would be to use one or two controllers like this:

or :
https://openinverter.org/shop/index.php ... duct_id=63
Re: Power generator, using MG1 + MG2 Prius 1 or 2
I wonder if anyone tried to make a controller like: https://openinverter.org/shop/index.php ... duct_id=63,
for Toyota Prius 1?

Re: Power generator, using MG1 + MG2 Prius 1 or 2
In your video, do you use the function of: buck converter to get 240 VAC? Is the battery voltage 12 x 7.5 v per element?
What power or current does the Prius 2's Hv battery provide? 10kw..20kw or much less!
"You need 2x Toyota Prius ™ Gen2 inverter controller because you want to use two cars. I would suggest not using MG1 to get started. Then you only need one controller"
Do I understand that the hybrid system from PRIUS 2 is similar or the same as the PRIUS 1, it also has a 32-pin plug for control?
Why don't you recommend using MG1? Can't I use them in parallel or mixed MG1 / MG? 2

Re: Power generator, using MG1 + MG2 Prius 1 or 2
I was thinking of similar application to power the 3phase network. I even experimented with some switchers and GFC. It allways dropped out when buck/boost was connected directly to the grid. That got me thinking that i would have to use 3phase transformer to separate the weaves PE and N from battery negative.
But then you can play even more! How about sending single phase harmonics into toroid transformer with 3 phase secondary winding to create 120deg 3 phase ? You would need like 64A at 230Vac working to 16A at 400Vac which is not too much power for household use...
So MG1 makes dc power to battery and MG2 side makes the single phase AC output from that. Then this weave is twisted using transformer into three 120deg shifted weaves that could power your house.
It would probably not be in sync with the network because of all the transformer lag, but it could be used to supplement the NET with what we have in OEM.

"So the MG1 makes direct current to the battery, and the MG2 part makes the single-phase AC output out of it. Then this fabric is twisted using a transformer in three fabrics moved at 120 degrees that could power your home.
It probably wouldn't sync with the network because of the entire transformer gap, but it could be used to supplement the NET with what we have in OEM. "
You suggest that the output of MG2 be injected directly into a three-phase transformer, without going through the hybrid system, in the case of the boost converter.
However, I come back to the original question: What power can only MG2 develop?

Re: Power generator, using MG1 + MG2 Prius 1 or 2
Pretty sure Damien had ~300A thru it, so at a dc voltage of 220, that'd be 66kW peak I do know MG2 is rated for 50kW, so at least that.

Re: Power generator, using MG1 + MG2 Prius 1 or 2
I was thinking that only MG2 reaches 50KW ... Does MG1 also generate 10kw?
My requirement would be max 10/12 KW

Re: Power generator, using MG1 + MG2 Prius 1 or 2
Do I understand that the hybrid system in this case "boost converter" produces 220/240 v at a current of max 300 A?
Re: Power generator, using MG1 + MG2 Prius 1 or 2
Motor rating, yes, MG1 was I thought 20 or 25 kW.

What power does it generate:
the inverter on the MG1 outputs?
the inverter on the MG2 outputs?
Aren't the outputs three-phase?

Re: Power generator, using MG1 + MG2 Prius 1 or 2
The system can operate in the following ways:
1..MG1, is driven by the gearbox sprockets, generates current to charge the HV battery and also produces current at the output of the single-phase or three-phase MG2 inverter at what power ..?
2..MG2, is driven by the gearbox gears, generates current, charges the HV battery (or does not charge), and at the output of the MG1 inverter we have single-phase / three-phase current at what power ...?
3 ... MG1 and MG2, are driven by the gearbox, charge the HV battery, and from here I don't know if we stop only at the option of charging the HV batteries or do we have other additional options?
Which scenario is best suited for producing single-phase or three-phase 220/240 VAC voltages

Re: Power generator, using MG1 + MG2 Prius 1 or 2
This statement applies to all HV batteries of the PRIUS series or only to the Prius 3:
Battery backup power is up to 4.4 kW * h.

"You can also buy two controllers and then use the MG1 inverter to generate single-phase output. Either directly from the power generated by MG2 or through the battery amplifier converter. Three-phase software may also be available, but is not yet supported. "
Does your controller control both MG1 and MG2 inverters? Or just one of your choice, either MG1 or MG2, or strictly just MG2?
In this case, do you need to use 2 controllers to use both MG1 and MG2 inverters? And if so, are they used in parallel on the same 32-pin plug input?
The ultimate goal is for the MG1 to supply power by rotating it in the gearbox, to charge the HV battery, and at the same time to convert the MG2 inverter to electricity of which I do not know exactly what nature will be single phase or 3 times single phase at what frequency. ? Can a three-phase transformer be attached to the output of the MG2 inverter for galvanic separation and correct voltage adaptation?
