I have a prototype assembly that was designed by a company that is now defunct. The assembly was tested but never used. It's an Ashwoods IPM 200-66 paired with a custom designed gear reduction that terminates in a female spline for attaching a standard drive shaft. It's intended to be used in...

I'm moving and need to get rid of this drive unit. I'll sell if for a good price, if it can be sold quickly. It's hacked with Huebner's / Damien's control board and very easy to setup. I will include ~6 hours of phone support to answer any questions you have and help you set it up. It's...

what version winding of the motor?

I made a video demo-ing a setup for one of the drive units: https://www.youtube.com/watch?v=IKiMBfrGqYQ I still have both a front and rear unit available. Any questions, ask away!

1. Yes 2. No

Hi guys, I have a few Tesla Drive Units that I need to sell. They are both front and rear induction drive units from ~2016 MY vehicles. They're all the ~250-300hp version. I have hacked them and will offer them "ready-to-run," along with a basic wiring harness and supporting components (main...

Just ordered €242 worth. Will be very useful for when I want to make some temporary packs and reconfigure later.

Mine were glued. It's a pita and not worth the time/risk to disassemble the module.

Cells are up for it. Bondwires, contactors, connectors, couldn't tell you :-D

The gravimetric energy density is actually slightly worse then the NCR18650GA

I suspect ~.00045 ohm per group or 0.043 ohm for the whole pack. Lower then the model s. That's room temperature burst dcir. I have no sources just speculation ;-)

Based on some more speculative estimates on my part, the Model 3 pack is probably capable of more power then even the P100D pack. Perhaps as much as 650kW in short bursts.

I thought I'd share what I have learned so far of the Model 3 cells. Made by Panasonic in the USA (duh) 21700 form factor. 21mm diameter and 70mm length. 4.8Ah nominal. 3.65V nominal. Reduced cobalt and increased manganese in the cathode compared to previous generation Silicone in the anode...

Exactly. This bms cannot prevent overcharge or regen. The current will flow through the mosfet body diode. Unless they are using a relay.
