Wanted: IVT-S shunt

Like topic says, looking for shunt for 1000A.

I'm in Sweden so somewhere in Europe preferably ;)

Did you do the oscillator-calibration correctly? It looks like the lights on the slaves are blinking in different frequencies.

Any preview of the design and wiring between SimpBMS -> Module -> Type-2 socket?

Price idea?

Re: Simp BMS

Oh baby. Is this fast charging in the making?! Nope, CP is for AC charging. No fast charging support planned due to hardware limits. Looks like J1772 support to me... Yes Type 1 (J1772) and Type 2 current limiting for the chargers so the EVSE remains happy. It will require a small external circuit ...

I am desperate for a converter plate and coupler solution for the Karmann Ghia/Leaf project I am working on. How did you do yours? Or did you change the transmission also?
Best wishes,

I also like your instrument display, did quick calculations on the Amps and Volts and it was around 80kW :D
Did you display the Amps and Volts gauge on a Raspberry Pi or Android? I couldn't see what the other gauges were.

Re: Voltswagen -64 "Leaf powered" Gen 1

Hi Langoo Do you find much difference or advantages / disadvantages driving the beetle with a CAN based controller compared to the other controller. I'm not particularly worried about speed or 0-60 acceleration. For example, I'm more interested in the torque when trying to climb a curb from a stati...

This is the Leaf. I have added the second gear to scale the diagram to a comparable size.

Re: 4-channel BMS with daisychain bus

I got the first 3 prototype boards from China today. Tested one and it's good. I found that I needed another gain correction in hires mode. Basically 4 correction factors for the resistor dividers and one for the internal 20x gain stage. Now the measurement is almost on par with my 34401A meter :) ...

Re: Leaf Gen 1 board

That looks very similar to the gen2 driver board. Looks like the other end of those resistors bugger off to the logic section on an inner layer. I'm sure it must show up somewhere. Why does the connector have a different pin count to the one on the controller? I attached an overview of the connecto...

Re: Leaf Gen 1 board

Damn it.. I mean thanks for checking ;) Even if it were PWM your multimeter would convert it to a voltage. So now I can either skip DC voltage which would disable meaningful precharge control or wire the remaining pins to a jumper link. Over CAN-bus do we get the DC-voltage reading so some how is t...

How far does the e-bubbla go per charge? :)
Around 70-80 km but I haven't tested it now with the CAN-BUS controlled inverter. Might be more efficient with Nissans logic board than with Paul's.
