Thanks for sharing this control info.
I implemented it in our LIN to CAN gateway and it works like a charm.

One finding from my end (relevant for EV Conversions): It self regulates when it reaches about 50 degrees.
So perfect and safe and sufficient for a battery heater (yet not suitable as an ...

why now?

I'm not 100% sure but my theory is:
They share the same 5V rail and due to slight voltage differences in the 5V USB voltage and the Teensy 5V regulator voltage, weird currents can occur. If the USB voltage is slightly lower the Teensy will try to 'charge' the laptop but that port is not ...

Myself I think this as “as per Teensy design”.
Hence the note on the Teensy card
Years ago I learned it the hard way with my Teensy 3.6.
Not sure what exactly is happening if you don’t cut the trace but high current from the laptop for sure.

That is a Teensy thing.
Sorry to hear that happened.
You either need to cut the Vin trace on a Teensy or use a modified USB cable.

Attached you will find a photo of the control harness that is included / part of the inlet.
And yes, the lock motor is included.
I think this is the harness up to connector T16g.
Ultimately it plugs into the OBC via a coupling point. These parts I do not have but I can include a print of the ...

Shipping to Romania is 25 ex VAT.
But I can do 170 ex VAT inc shipping.
The port and the wiring that is directly attached to it is all I have.

First of all thanks to Damien for doing the hard work on finding the ID's and Alibro for the logs. Today I played around with my MG PTC heater.
It is all Damien said +:

Control is in byte 0+1 of 0x2E
Scaling = x25
Little endian So if you want 20% power you need to send decimal 500 which is hex 01F4 ...

Another round of reducing the amount of hardware 'for future projects' when I have time.
A DC/DC from an Volkswagen (ID.3 or ID.4)
Part 1EA.907.190.D
Comes with pigtails for both LV and HV and an extra control connector housing.
125 euro ex VAT + shipping (from The Netherlands)

Sold, thanks

New old stock.
Comes from the Azure dynamics Ford Transit liquidation sale.

50 euro, shipping from The Netherlands possible.
Private sale, not VAT.
Some info here https://malfunction.faed.name/2013/04/a ... oning.html

This PCB can be used to PWM control the Tesla water heater (see Wiki).
Untested, should work.
Therefore 25 euro + shipping from The Netherlands.
Private sale so VAT not applicable.

Sold

Please delete this topic. Too complex, and too much for future idea's. No longer needed.

Maybe a long shot but worth a try.
I'm looking for the outside and inside piece and bolts of the header on the Tesla Model 3 battery that accepts the HV cable for the motor.
Here is a screenshot of the outside part

Due to a customer changing plans I have an old but new AC compressor available.
It is PWM controlled.
Pinout and control scheme comes with it but that's it.
Connectors not included, but I will share part numbers of the ones that should fit.
No datasheet so not 100% sure.
Also no warranty and no ...

I'm clearing out my Tesla Gen2 OBC hardware.
I have one OBC left. It works but it has a humming noise when charging.
Tested at 7A at single phase.
Part 1014963-00-C
Comes with:
- Multiple connector kits (both control and AC and DC)
- Two logic boards new, fully assembled with connectors
- Spare SMD ...

For those using Orion BMS this might be interesting.
No longer need it as I use other BMSses these days.

Asking price = 190 euro ex VAT (VAT added depending on your country if not B2B).
Shipping from The Netherlands possible.
To the US difficult (read: expensive, UPS only) at the moment.

Sold, thanks

Still available.

Maybe you want to read my blogpost before proceeding (and/or even recommending that option).
https://www.oldvolvo.com/blog/what-caused-my-electric-car-fire/
Yes, it is possible and maybe even safe if you make 0 mistakes. But 1 mistake can have big impact (see above).
I choose that path back in 2016 ...

That is a UP28 which is a supporting pump and not powerful enough to be used as a stand alone pump.
See also my blog https://www.evcreate.com/vacuum-pump-power-brakes/
A UP30 is the smallest one suitable as stand alone (but noisy).
If you want vacuum. I ...

A boat is a different game compared to a car.
In a car at some point you will start reducing throttle because you go fast enough already and get scared.
In a boat you can (and even need to) apply (full) throttle to retain your speed. Thus there is a higher current for a longer period of time. This ...

I'm interested. In particular in the 7 kW version as it likely is portable.
Have send a message through the forum, but have not heard back yet.

Likely because the Zombiverter is better at trying to protect your cells.
In the Leaf demo you are seeing a serious undervoltage error of 2,7V.

IMG_6458.jpeg


Since the lowest voltage before load was around 3,6V this indicates the pack is really shitty. Allowing the cells to go down that low ...

Your truth, but... The Leaf system is running smoothly.

Smoothly?
A 400+ mV delta does sound like a weak pack or at least weak cell to me.

Delta 453 mV.png

But if you are seeing a voltage sag of 80V at 300V that is not good.
Then you are allowing the inverter to draw way to much current.
So ...
