Re: EV Conversion using prius gen 2 inverter/transaxle


It all works in principle but the light bulb limits current too much. Take it out, set fslipspnt=1 and gradually increase ampnom from 30% in 10% steps until you get movement. Then increase fslipspnt.

I will update the wiki once this is tested again.

For my own info, is the fact that this test ...

Re: EV Conversion using prius gen 2 inverter/transaxle

I would have done as per Damien and Johus FOC video - see around 30 min point and see if you get the same results.
I think 3 amp/12v is too low for your HV circuit. Use a 12v car battery if you can, along with light bulb for protection.

Re: VW GTE 3.6Kw charger 5QE 915 682 AF

I don't see any actual values in VCDS relating to the maintenance or pilot lines, and I have yet to find anything relating to them in the CAN messages. Their voltages do not seem standard either. But in a normal oem setup, either of these signals would flag a fault and cancel any charging. I'm ...

Re: VW GTE 3.6Kw charger 5QE 915 682 AF

I have the stock set-up with the flap locking mechanism and LED push buttons. If I reset to factory settings, the lock fault is erased, until I activate it again. I have a type 2 charger plug connected so normally there is no over run of the locking actuator.
I've looped the HV connectors for A/C ...

Re: VW GTE 3.6Kw charger 5QE 915 682 AF

Two other items have come to my attention that might need spoofing
1 - the PILOT control signal
2 - the MAINTENANCE plug signal

Both signals give me values between 8vdc & 10vdc if I create a short circuit using myself (resistance) between each wire & the battery positive pole. This could be a pwm ...

Re: EV Conversion using prius gen 2 inverter/transaxle

I was talking about the light bulb on your High Voltage circuit. Do you have a power source connected to your inverter, with a light bulb in series in the circuit? It is your fuse if there is a dead short -the light glows brighter the more there is a short circuit.

Re: EV Conversion using prius gen 2 inverter/transaxle

The pins 11 and 12 receive 12v via a switch to power each pin according to the direction selected. They are not connected directly to 12v. I will have to document this in the wiki.

Re: EV Conversion using prius gen 2 inverter/transaxle

That is awesome news!
The best way to help is to look at the wiki and suggest how to update it so as not to have some one else making the same mistake.
Did I understand you provided 12v to Pins 11 and 12?

It is identicle to the charge flap actuator on the GTE looms, however it has a 4 pin connector, so cutting out the original actuator on GTE loom, & fitting a plug, the actuator can be replaced ...

Re: EV Conversion using prius gen 2 inverter/transaxle

Sorry, but it seems that without connecing the adaptor board to the inverter, the DESAT error blocks Manual Mode.
So unless some one knows how to "spoof" the DESAT error, I am not able to help with further initial testing..

Thankyou @Bigpie & @manny for the final pointers ! Pins 16&17 are moved to 1&3, and on different boards.
This highlights again the need for up to date links & info "for dummies like myself". I'll put these findings with links into the wiki as it ties up with other threads.

This is where I took info.

"Hardware
The web interface has been initially designed to run on ESP32-WROOM-32E boards.
The connection to the inverter are on Pin16 (Rx line connect to inverter Tx line) and Pin17 (Tx line connect to inverter Rx line)."

So I will go and check if Esp32S3 dev are the ...

I found an original ESP8266 board. Long story. It's running 4.87R-sine on what I think is the original Web Interface.
I connected 12v to the adapter board.
Modified Udcgain & Udcofs to make the board think there is Udc - 5vdc

Re: what am I doing wrong ??? ESP32 flashing

The jumpers are soldered into the board, but I could replace them if there's a doubt.
My issue at the moment is around connection between Esp & STM.
If there is doubt about the ESP board, is there a "simple" way to say put the web interface on my arduino due and connect that to my adapter board?
