Audi A2 Prius Gen2 - huh again?
So here we go again. Like I might have mentioned elsewhere my friend Thomas as an infinite stack auf A2s in his back yard and we have pretty much committed to converting another one.
The USP here is that it will be almost an exact copy of the first one So we want to find out how quickly we can pull this off on a known car with most parts pre-ordered and pre-fabricated.
Some things will be different though:
- Larger batteries. 30 or 40 kWh Leaf would be an obvious choice but I'm sure there is better bang for the buck available
- Proper battery box
- CCS fast charging
I'm not super keen on opening up the gear box. I would think when the input shaft is not locked MG1 shouldn't be spinning at all. I don't want to experiment with it as performance of MG2 is good enough for cruising. Only thing I would consider is removing MG1 rotor and stator as well the planet gear rubbish for some weight saving.
So, more importantly which 400V/30kWh-ish batteries are on the market ?

This is going to be cool, though different battery might add more time for integration.
I think there's a DBC the covers the BMS master messages for the VW. It's all in German but that's not a problem for you.

Yes absolutely. If I manage to swap an MEB battery into Touran by then I could just use its 40 kWh Leaf pack which is mechanically identical.

Re: Audi A2 Prius Gen2 - huh again?
Is this the start of a dedicated Audi A2 conversion business?
The first one took months, the second one weeks and every further one only days

Re: Audi A2 Prius Gen2 - huh again?
Yeah why not The chassis can't rot and most owners are rather ecologically minded.
Arber was asking somewhere else about the TÜV battery bumper distances.
Sides: 200mm, front 420mm, rear 300mm
The way I did it in the first A2 conversion by far exceeds these distances because the battery is in the middle.

I am sure i would find space to put in much more kWh .johu wrote: ↑Thu Sep 14, 2023 3:19 pm Yeah why not The chassis can't rot and most owners are rather ecologically minded.

Say does that requirement about distances include heater, charger, DCDC and inverter components?

No, just the batteries
Thing is, the car is so aerodynamic that it doesn't need a whole lot of energy storage. I reckon carefully driven it could go 400 km with a 40 kWh (usable) battery

BMW i3 32kWH and 40kwh working with simpbms are maybe also worth a look.

Re: Audi A2 Prius Gen2 - huh again?
While I still think it would be interesting to see MG1 and MG2 working together, the weight saving of removing MG1 is interesting as well. But I'm not sure it would have much of a measureable benefit.johu wrote: ↑Thu Sep 14, 2023 7:56 am I'm not super keen on opening up the gear box.

But at least you have a comprehensive video on how to assemble the gearbox again from Weber State University on YouTube
And considering that you can get a Prius 2 gearbox for less than 250€ delivered from Lithuania or Poland, the risk is quite low.

Re: Audi A2 Prius Gen2 - huh again?
OK, OK lets not get carried away here. Myself i tried to drive slowly and carefully back in 2014 and;
a. I would immediately became road hazard as everyone wanted to overtake me;
b. there are so much hills near me that even driving slow cost about the same energy;
I recommend at least the same emotor power into the car that the dinosaur juice eater had before.
Aerodynamics is really good with some cars and A2 being a bit illogical as it is so high. However it is very light and underside is completely closed. We have seen what that would accomplish in Prius and Ioniq.
I read about Audi experimenting with some fish shape when designing A2 .
Re: Audi A2 Prius Gen2 - huh again?
I have some A2s waiting... Have not build a garage yet
sorry if i missed. what motor you will use for these? Prius Gen2? these are really cheap

Re: Audi A2 Prius Gen2 - huh again?
will we be seeing a Prius Gen 2 motor/inverter mounting kit for the Audi A2 in 2024 ?
