Re: Outlander VCU - Rear inverter, Charger and BMS

Question 2: I have made a really good pedal map setup for me i think. The only thing i am bothered with is fast torque transition when i am already rolling, maybe between 250rpm and 500rpm. There is a weird shaking there but then it becomes smooth as i go through the rpm. What would that be? Are th...

Re: Toyota Prius Gen 2 Inverter Controller

Hmm, no. The only thing I know about the encoder is that it's a superseal connector that goes into the far side of the motor. ...... Nothing in the spec sheet identifies the encoder other than its pinout. https://www.dynapar.com/technology/encoder_basics/quadrature_encoder/ Ok, then your best bet w...

Re: Tesla PCS DC/DC turns off during driving

Hi. I've now experienced this twice in a short time. The DC/DC turns off during driving, resulting in no charging of 12V battery and me loosing steering servo and heating in cabin. Any ideas what can cause this? Unfortunately I don't have any loggs or error messages. The DC/DC output seems to be ar...

Re: Outlander VCU - Rear inverter, Charger and BMS

Thank you for explanation. Question 1: Would tpsbins[21] mean pedal position from 0 to 3% and then 3% to 5%? Is your intention in the lower part of the throttle to be really accurate with pedal position? So if i would change your pedal map to... const int tpsbins[21] = {0, 5, 10, 12, 14, 20, 24, 28,...

Re: How to not kill a tesla drive unit

Hi Everyone, I have spent extensive time developing 3 phase inverters. ..... I will also comment IGBTs are usually quite slow. 1uS dead time is likely too short or just on the edge of what is ok. My first inverter using Fuji IGBT moduals and good gate drivers needed 2uS dead time for instance. -Arl...

Re: Toyota Prius Gen 2 Inverter Controller

What you are doing is done with IPM motor with resolver. If i understand you have ACIM and dual channel encoder. Four wires channel A, B and +12v, gnd. Inside the brain this is converted to quad encoder position but you need to input how many pulses does single channel make. You count this by puttin...

If I had a 100kWh Tesla battery pack powering two Openinverter Tesla SDUs, could I simultaneously use both units' onboard 5kW charging capability to charge the battery at ~10kW? Did you mean AC charge via the motors? I am not sure the circuit would see this any different than AC charging in paralel...

Re: Bosch Accelerator Pedal pinout?

Yes thanks I found that one also, but I dont measure resistance like that. Only 22kOhm over 2 pins, nothing on the rest. It really has a PCB with an IC in it, so it probably only works when powering the right pins with 5v Some of those pedals have partial resistance inside their casing, but the res...
