There are a bunch of different components in the Gen2 (and onward). There's also a 3phase inverter for the 3ph air conditioning motor too. But apparently that's on the motor itself and just power leads head over to the A/C motor. Prius Controller Disassembly -- Timestamp to the end of the Gen1 disas...

I think so. Damien hijacked it as a battery charger already IIRC.

No worries of corroded contacts or UV degraded brittle plastic. I get what you mean, but... This connector is inside a sealed box, never exposed to sunlight or moisture. Everything else in the case looks like it's brand new. I have more confidence in Toyota fabrication than my own crimping and asse...

Just went to check, it's the same plug as on the Nissan Leaf LBC. Part number housing: 1318747-1, Pins: 1123343-1 Digikey even has those in stock. $5. What's do the "pins" numbers mean? [Edited to answer: The plastic plug is one part, but it does not come with any metal connectors. You ha...

Tidbits of progress: - Arber333 helped me clarify what type of Schottky diode I need. Also, on Damien's Prius Gen2 DC board, he has a similar reverse-polarity protection diode that's rated 40V and 5A. I couldn't find anything at Digikey at either 4a or 5a, so I went with a 3a, which Arber said shoul...

Second, less important question; if I add kWh's to my battery system by increasing the Voltage as opposed to increasing Ah's will this actually give me more range or just higher performance? There is no free lunch. The way that you shuffle the battery does not add or remove the amount of battery. Y...

TL;DR - Open source philosophy, blah blah. Unrelated. This is a very interesting thread as it shows many of the implications us developers make. That's the essence of open source. In my (limited) experience: - Top tier of contributors are those that can solve the problem well. Their skills are rares...

2 - As far as I can tell it's implemented in Johannes releases.. https://openinverter.org/forum/viewtopic.php?f=7&t=382 Ahh. Well that link just leads to another link, but that link, is: https://github.com/jsphuebner/stm32-sine/releases/tag/v4.64.R Which is an undescribed directory with a half-...

Quick question, more applicable to everyone than on my personal build thread... Does anyone know what the connector(s?) inside the Gen2 inverter is(are)? I'm presuming I'm going to have to hook that up to Damien's board. Other than chopping off the plug and splicing wire-to-wire, it'd be nice to be ...

1) Digikey.ca have current stock of19,496 TO92 BC547 transistors, Part # BC547B-APMSCT-ND. Why do you say they are obsolete? No more obsolete than the STM32F103C8T6 used on a Blue Pill. Err, my mistake. The BOM lists that the BF959 is obsolete, and this is the replacement for it. The one you linked...

More dumb beginner questions. Current roadblocks: 1 - Can't figure out what parts to buy to populate the Prius board. I just lack the context of the circuit to know what to order from some of the items in the BOM, as listed above. Also, what connectors I would need to interface with the controller. ...

Three things arrived in the mail today: https://mattsawesomestuff.com/Projects/Vehicles/Opel/Opel%20EV%20123.jpg The Prius V2 board, the Blue Pill, and the ST-Link to program it. All purchased about the same time, one from overseas and the other two a day's drive away. Y'know, you try to support loc...

AwesomeMat, the bloke that removed the cables had to open the V2 to get the HV transaxle cables out of it, and they also forgot to put the 6 bolts back. Yeah, I figured that out shortly after. The case screws were only finger tight too. But, other than lying about that, seems to be undamaged. I won...

The computers arrived on Friday. Shocking. Partial faith in the postal system restored. Maybe Damien's board will show up soon too. Wanting to order parts, but, still have some of the above questions as to what to order: 1 - What transistor should I order to replace this obsolete one? 2 - I presume ...

The blue pill is based on a design which is no longer manufactured by it's creator. I doubt you'll find it on digikey or any of the major electroncs distributors. Ebay or a plethora of Chinese sites are your best bet. Oh, I see, it's an actual named thing. I presumed people here were just calling t...

1. More like N2222a GP signal transistor, though gain is different 2. Capacitor, EU type 5. Low resistance rectifier diode 6. ? The cheapest STM32 module I understand generally what the components are. My questions were more, specifically what do I buy? I (and certainly not a novice) don't have the...

Assistance needed I'm going through and making an electronics order from Digikey, using the BOM here: https://github.com/damienmaguire/Prius-Gen-2-Inverter/blob/master/PriusG2_V1_BOM.ods I do this like, once every 5 years on a project, so, I have basically no idea what I'm doing. My opinion of the ...

Purchased!

6500km away, on another continent.

Also today I purchased something from within my own province, a few hours north. It gave me a 3 week estimated delivery time. Let's see which gets here first. Should be neck and neck.

Jack Bauer wrote: ↑Sat Nov 09, 2019 7:49 amYep that's the one you need.

Whelp. Damnit. It's sold out before I could get one now.

Or was that a glitch that they never got entered into stock?

AFAIK, Damien's board there is used for development, i.e., it's not a replacement logic board. I'm not sure if I understand this correctly. Are you saying: 1 - That the board is not going to fulfill that purpose, it's just to help people reverse engineering. Or, 2 - To not expect this to be a finis...

I guess my first questions would be... What should I buy? http://evbmw.com/index.php/evbmw-webshop/toyota-bare-boards/prius-gen-2-inverter-bare-logic-board <-- Is this the correct thing I will need to purchase from Damien's website? And, has anyone built a BOM for it yet, so I can start ordering par...

Figured I should create my own thread here rather than butting in on the actual controller threads. The purpose of this thread is mainly the inverter side of things, and the electronics side of things, since the braintrust of DIY EV electronics seems to have gravitated here. I won't re-document the ...

Let me know if I should be posting this stuff in a project thread instead of here. Picked up the 2009 Gen 2 inverter. $150 CAD. https://mattsawesomestuff.com/Projects/Vehicles/Opel/Opel%20EV%20115.jpg Came with literally nothing other than the inverter itself. I asked what the hole was for and what ...

You can probably get the cables from another wrecked car. These things are everywhere. I live in the Canadian Prairies, where the oil and gas industry suckles across the land and cities of 100,000+ are 3-8 hours drive apart. No one drives a Prius. Pick N Pull only had one by mistake (a Gen 1, thoug...

I have found a 2009 Prius (Gen 2) inverter for $150. But, the shop has already pulled it and gotten rid of the vehicle, so, no cabling or wiring of any sort apparently.

How significant of an impediment is that going to be for me?
