Applying offsets in CAN Mapping, and general CAN Mapping

Hi everyone,


I am trying to setup my motor to output certain messages on the canbus via the web interface.

For the Motor and inverter temperature, I want to apply a +40 modifier on the temperature reading. How would this be done?

Currently I am putting in the interface 1023 0 8 1 TX. Would the ...

Re: Tesla Gen 2 Charger won't charge after first setup

Ok so it sounds like I need to both terminate the bus (even though I'm not using CAN), and also put the PP pin to ground?

Do I understand that correctly?

Re: Tesla Gen 2 Charger won't charge after first setup


did you go through the common issues on the wiki? https://openinverter.org/wiki/Tesla_Model_S/X_GEN2_Charger

None of your info for the phase modules populate also there seems to be no HV connected to the charger. Please also not HV to the charger and the AC voltage being applied must happen at ...

Tesla Gen 2 Charger won't charge after first setup

I have a Gen 2 tesla Charger with the open source board in it. I am using it with a Vero BMS and their j1772 charge controller.

Since this is my first time using this charger, I set it up as simple as possible. It's in manual mode so once it receives power on the enable pin it should start ...

Re: Help! Power lost and motor shutting off.

If 900a here means dc battery amps, then I am for sure no where near that amount of current. I'm lightly accelerating when the trip happens.

Reading in the documentation it says that this number should be negative if il1 and il2 are negative. Looking at my spot values, and they are indeed negative ...

Re: Help! Power lost and motor shutting off.

Hmm, that's strange. I measured the voltage with the pedal fully pressed down to be 3.2 volts. It seems I have it set to a maximum right now of 4 volts? Also, It cuts out well before I can press it all the way down. So I would assume the motor is seeing even less voltage on the pot line.

Does that ...

Help! Power lost and motor shutting off.

Hello everyone.

I went for my first drive yesterday with a LDU. While I was driving if I pressed the throttle too far, it would immediately cut off power to the motor. It feels very abrupt and feels like hitting a speed bump. Sometimes I need to restart the car, other times I need to come to a stop ...

Re: BMW i3 LIM voltage measuring board

Hi,

I am interested in purchasing one of these boards. Do you send us a paypal link, or how would we go about paying you?
