Re: Transaxle Modifications

The gen 3 transaxle requires welding of the power split device as like the gen 2 the oil pump is mechanical and driven by the ice input shaft. Any reason we couldn't run a small motor on the ICE input shaft to keep the oil pump happy? Keeping the transaxle sealed has a lot of advantages especially ...

Re: Transaxle Modifications

Unless I am missing something important, the Gen 3 only needs an external modification to mobilise the ICE input shaft. It is designed and therefore already approved to run in EV mode up to 61mph using MG2 alone. There is potential to boost further with MG1. T In this video Professor Kelly suggests...

Re: EV car conversion hardware

So I need to attache them back? If you run a contactor that requires an economizer without one then you'll burn out the coil. We had the Tesla Model S/X contactors on the bench this week. I can confirm they consume ~2.5A @ 13V and get very hot. They require an economizer. IMG_20200826_150614.jpg

I've been experimenting with terminating the screens on Tesla HV cables. For the 35mm2 SDU cables I used three ferrels which had the screen braid sandwiched between them. This sandwich was gently crimped with a 95mm2 die (being careful not to damage the insulation of the central HV cable) and then h...
