Re: [FIRST DRIVE] 1998 Nissan Frontier Minitruck - LEAF 40kwh

Good job :)

One things I noticed, the vacuum pump comes on often and could use some turn-off hysteresis. How is it controlled?

Re: ID.3 and other MEB battery packs in conversions

Yes, its a remix of Toms code and tailored for 8 modules:

Re: Driving mechanical speedo from CAN

Welcome :)

An arduino can hack it. You'd not use 0-5V but rather PWM as that is more common.

When creating new threads use a descriptive title. I've changed it for you

Re: [Driving] Freelander EV With Gen1 Leaf electrics and EVBMW VCU

You could move the "negative" contactor between 48 and 49 and move positive and precharge to the end of the pack. Don't break between 41 and 42, by Murphys law this can and will go wrong

Collection of Part Numbers

Following up on a kind nudge by no one else but The Greg I created a wiki page where we can collect various part numbers for connectors, even if this creates redundancies to the existing detailed board pages.

Re: Volt Contactor Amp Draw

I have clarified this sentence in the wiki. Putting two contactors in series doesn't double their current capability and I'm sure it's not what arber meant to say. They need to be paralleled for double current capability

Re: Am I to dumb for Open Inverter

Leave out all the contactor stuff for now and connect the battery directly to have less room for errors.
FOC itself doesn't care about the voltage but udcsw and udcmin should be set to 0 for the first tests

Re: Big-Endian CAN mapping

Hmm, the bit order shouldn't be changed at all, just the byte order: word = (bptr[0] << 24) | (bptr[1] << 16) | (bptr[2] << 8) | bptr[3]; I think it should be consistent with SavvyCAN that the position now specifies the "end" of the data item. So little endian bit 0, length 16 becomes big ...

Forgot the obvious: when the inverter is in Run mode it won't save (because it interrupts the control loop). It must be in stop mode. The CAN Ui doesn't report this yet...

The latest web ui hides SWD update as it only works with additional connections. And even then it never really worked for me :(

Re: First-Time Config of FOCCI And CCS1 vehicle charging

I think the 5% PWM should start as soon as the charger is powered and you have 2k7 pull-down to PE (not PP). When you say "PP" do you mean "PE" i.e. Earth? Doesn't really make much sense to measure between CP and PP
