Not possible, you cannot splice charge point signals.

Please provide the parameters of your charger settings.
Please provide pictures of your setup.

Re: Zombieverter PWM setup for dummies

Write code for it, you can make it as interactive and configurable as you want. Have a look at functions/parameters that do something similar.

"easy example"
Param Output Function: CoolingFan
Param: FanTemp

So many options, for testing don't worry about it. just do it manually.

Re: Zombieverter PWM setup for dummies

First try can be just to use the PWM outputs and its parameters to get the 2hz output and then tweak the duty cycle to see if it works.

No need for any code changes to run a fixed PWM duty and frequency, if you do not configure any PWM functions

If you add it inside charger module, just like Foccci ConfigCan function, I could try it even there is no parameter for it.

Re: Nissan Leaf (and Tesla) coolant pumps

Not sure that 2hz (what the pump wants) is achievable with the fixed prescalar, I have not tried it. EDIT:your values appear to be under 16bit so it should work.

using TIM3 and modifying anything there adjust ALL pwm output frequencies. There are only two frequencies possible, one for all PWM ...

Re: Leaf Current Sensor instead of IVT-S [SOLVED]

Sure a current sensor would that. Usually that is connected to a BMS that then sends that info to the ZombieVerter.

Just reading current is not enough usually.

Also analogue sensors are quite finicky to get the readings correct and repeatable so best to reuse as much OEM hardware en software as ...

You watch any of the Damien youtube videos? The Leaf BMS is implemented in the Zombie release 2.20A.

Re: Leaf Current Sensor instead of IVT-S [SOLVED]

Not possible with the Zombie as it is not coded in.

Do you have specs on what the leaf current sensor is?

If you are talking about CCS I would expect you to have a BMS and the BMS should be measuring the current and reporting it.

Re: Using Zombie with Leaf Inverter


From firmware 2.20 you no longer need the IVT-S shunt.


Not correct.


Does the Leaf inverter already measure current internally


It does not measure current, it only measures voltage, you do not need the IVT-s to do precharge. So you can run the leaf stack without an IVT-s but you would not ...

Key to all of this really is, whre are you based and what are the legal requirements when doing a conversion.

A leaf motor and drivetrain wont fit without subframe modification. So in some countries is not legal.

Do you have a CAN log of a running Volvo with the same ECM in it?

Get a CAN log of your car now with the ECM in it and the engine not running. Then you can compare.

This is the way its coded, same in OI firmware. Believe its done to allow some back flow of power when the main relay gets dumped under fault conditions.

It is not usual practice in an EV, so can be removed at some point. Needs a bit of rework anyway.
