Which DC-DC are you working on? I'm helping an old auto salvage client, Nordstrom's Auto, with a couple chevy Bolts right now if that is any help?

I never figured GM as designing anything for production, merely specifying functional modules to their suppliers. OEM's do a bit of both. Specs are published to suppliers and once a design is chosen we help to ensure the design standard throughout it's production. In recent days that means coming u...

Greetings All! This week I accepted an offer from GM for inverter electrical design and can't begin to thank everyone involved here enough for providing the resources to achieve my dream job. Damien and Johannes specifically though deserve a thanks all their own as we all know much of what we have w...

I can certainly find that out but I would guess so since it is designed to push atf into bearings and is located after the radiator. I forget where I found the info but at some point I found posts talking about how bmw has a trans oil pump with the same pump core just different housings as the OEM 4...

I know some have had questions with regard to another option for oil pump and think I may have a solution. I'm currently converting my highlander hybrid to EV and it contains a cute little oil pump that is reasonable and has easy hose connections HERE I'm also converting a BMW with the full 450h tre...

Lapping the contact surface of the IGBT copper base plate and mounting surface of inverter housing would give you the best results. I believe warping of the inverter housing over time would cause the igbts to separate and any uneven heat would more than likely be the result of that and not bad therm...

Re A/C: It's probably quite easy if someone with an actual Prius can sniff that 6-pin connector. Lacking technical expertise, I'll try doing some outreach on Prius forums or something. What exactly would be the task I am asking? Let's presume the people I'm reaching out to are nerdy EEs who drive P...

Would it be possible to keep the ICE and add a 600V+ battery to the DC bus terminals? I want a full plug in hybrid out of my highlander hybrid and not be limited to what the boost converter can provide.

https://nicjam.es/projects/derptruck/part_2/ There is some good data here on using the gen 2 as a dc motor controller with the limiting factor being that the gen 2 has an output of 40kw total for a brushed DC motor with a glance at page three

Are you just looking for a 12v DC-DC that comes on with application of HVDC?

Have you checked output with a scope to see if you are getting pwm? This is one of the first steps setting up these systems since it allows you to test for inverter function without needing to fully power on. If you aren't getting pwm out then we shouldn't even be talking about any high voltage.

Leaf motor?

:D Very cool, now you can forego ordering the connectors. Why are they filled with toothpaste or something? Attempt number 2 started with connectors filled with an oil based clay which ended up melting a bit and being completely unnecessary! Im more a cast iron skillet on the stovetop guy. Same met...

Got some bad news on the rewiring front, the MGR consists of 48 poles meaning 16poles per phase and 4s4p configuration. I've designated the half dozen transaxles I currently have as engineering samples so if anyone has any recommendations for rewiring I would be happy to hack at the windings without...

I do have a confession of having more redneck hobbies in the Pew Pew realm. In the past I was heavily into casting my own projectiles and thus have significant quantities of pure-ish lead in storage. This is the setup I use to process scrap lead so it was just a matter of dropping in a few ingots an...

Guys I would like your opinions on a couple different methods of charging using high output server power supplies. 1. https://www.ebay.com/p/1641499866 Involves a 12v c7000hp 2.4kw power supply that features power factor correction, 120-240VAC input, and are easy to separate the dc ground planes to ...

I've just recorded a VERY rough measurement template, but I'll get more dimensions of the inverter and gs450h trans. I've also got a gen 1 and 2 camry inverter along with a RHD LS600HL inverter to compare against the 450h inverter as well. If you can see the rough dimensions written down, take note ...

I've used 2x IBM (ARTESYN) for 24V. Isolation important! + a signal wire. (server power supplies do not turn on by themselves) Server PSU 24v Wiring Diagram rev4.png Here is info for the IBMs https://www.rcgroups.com/forums/showthread.php?2662901-Converting-two-Artesyn-7000758-12V-42A-to-24V Normal...

Cracked it open and what a beauty!

Prius gen 2 shuts off when one of the phase currents gets too high. But not to worry, the limits are pretty darn high. Prius Gen2 shuts off at 460 amps on the high-power side, which is about as much as anyone needs. Maybe the RX400h will push 600 or 800 amps! Damien did some power testing on the Ge...

Those bus bars look much thicker than the Gen2 Prius, which is about similar in year. So I wouldn't be surprised if that's got way more current capability. Prius Gen2 is factory rated for 50Kw. MG2 in the RX400h is rated for 163hp, which translates to 120Kw. I'd say lots more power. Also looks like...

Seeing the prices are in dollars, you are in 'the states' then? Very interesting post, and thanks for sharing. We are in the states, South Dakota specifically, however shipping outside the US is still possible but will cost extra. My company is also partnered with a local university to study batter...

Hey All, I'm trying to gauge interest in cheap OEM Hybrid and EV parts and Batteries! Price Includes Shipping in Continental US, to a Hub Near YOU! Please feel free to contact me with any other specific part requests and I'll see what I can find! I have access to just about any OEM part one could ne...

What we have her is an 06 Lexus Rx400h FWD inverter. This inverter seems substantially more powerful than a prius inverter but I am far from an expert at this point. Let me know what you guys think. I would like to use the dual motor board with this inverter. What would this inverter be rated at com...

My needs for a cheap and powerful DC power supply led me to server power supplies. There is an abundance of info out there on different power supplies you can use but most of which have a rather complex and error prone process to use in a series string for higher voltages. The psu I picked is from H...
