Re: Porsche Boxster 986 Tesla conversion [FINISHED]

A few pictures and meandering thoughts following my recent Tesla gen 2 charger installation with V5 logic board. I have the same orientation of the charger, and I have trouble with overheating of the top module. I'm wondering if it's possible to make some air bleed or vent in the top, to get coolan...

Re: Tesla Charger Support Thread

I’ve been playing with my freshly installed charger today. You’re right, it needs the 12v a few seconds before AC. I’m going to leave mine permanently connected and work towards having the DCDC kick in when the 12v battery dips too low (also for running the water pump during charging). I have a ree...

Re: What is wrong with IGBT driver? [SOLVED]

The strange thing is that the "fault" is on POS and NEG, the driver has no common components for POS and NEG side? The only thing that is common is GND and 5V PWR. DRV_circuit.JPG The scoop capture is still picture, in real time there it's more fault noise/peaks, when i put more power to t...

Re: OpenInverter Mainboard in a Siemens Simotion?

One of the optocoupler is OUT from the IGBT driver circuit! Ok, do you know in your inverter what this output signal is used for? Not sure but I would guess some fault/desat out signal from the HV side of the IGBT driver circuit. In theory is should look something like this: figure2.png I'm wonderi...

Re: Ford Ranger Inverter board Support Thread

I do not know which battery pack and BMS to consider at this time. Highest capacity at best value ($) should be the default answer, but ease of repackaging donor batteries into the Ranger coffin is certainly a consideration as well. There is plenty of room in the coffin, off course depending on how...

Re: Ford Ranger Inverter board Support Thread

It's just no link to it when you go to the wiki.
So you have to know the exact address :?
I could fix it, but I don't want to mess up the ongoing cleanup/reorganizing.

Charger stop charging at that voltage, set it a little higher than the BMS shut off voltage.
Remember to test it, because the charger don't measure accurately.

Re: Can I use spot value "TURNS" for km trip counter?

Thanks for the info.
If I understand it correct, this would be the way to calculate it?

Wheel is 218cm (0,00218km) for one rotation
Gear ratio is 12.518:1

Code for km travel would be TURNS * ‭1.741492251158332e-4‬
Or for m travel TURNS * 0.174

- The PWM outputs (inverted logic) are clean when coming out of the main board. However, when connected to the opto-couplers on the driver board, their amplitude decreases drastically (on both ends: the signal does not decrease to 0V and is only slowly reaching 5V, see oscilloscope screenshot attac...
