GS450H gearbox with Camry inverter G9200-33171 [SOLVED]

[PetersonOctavius]

Hi there, got some updates,

i connected inverter to vcu and to the gs450h, it spins, i can enable mg1 only or mg2 only. spins both direction and everything.
i went ahead and installed everything in the car (with everything i mean the camry inverter, vcu, gs450h and also a telsa gen 2 dcdc conv).
problem is with the wheels in the air i get spins in both direction. i didnt lock the input shaft, planning on using mg2 only for now.
when i put the car on the ground i wants to move but its not moving
with mg2 only selected on the web interface, i hear the motor spinning but the car doesnt go forward or reverse. it feels like it want to but it has not enough torque. transmission slipping? idk? transmission fluid i full.
feels like something mechanical. i went ahead and ground SL1 and SL2 manually but nothing.
oil pump is installed but not connected.

any help would be really appreciated.

So you have no gear selected in the gearbox. so no drive, the output has resistance so it will free wheel the gearsets. One of the gearset needs to be held by oil pressure.

[PetersonOctavius]

In what state do the solenoids have to be?
When left unconnected it did the same thing…
That means no oil pump no torque output?

Thanks for the fast response

[robertwa]

Yes, the oil pump needs to be running to generate torque

[PetersonOctavius]

I ll go ahead and wire it up

[PetersonOctavius]

And it moves!! Many thanks tom and robert

On to the next!!
Power steering…. I have a prius power steering motor but there no space between the steering wheel an the rack to fit it… so i ll have to go the volvo way which is easier to install but noisy

The audi came with an electric vacuum pump and a vacuum sensor on the master cylinder which is great. I already found the relay and the pin to control it, but i have to find out what the sensor sends so i can control the relay.

Dcdc is already installed, just need to wire it up.

Im getting a model y battery pack. Sadly we know that the pack consist of those long modules so Im thinking of rebuilding the pack so it fits in the car.
Hopefully i can use the oem bms.
Not sure about the PCS since not all of the pcs are compatible with Damien s board

So far good!

My wife and i are expecting a little boy by the beginning of may, the plan is to get it ready by then as i wont have much time to work on the car.

[PetersonOctavius]

Happy new year all !!!

a friend of mine has a tesla model y, i think its from 2020. his battery pack would not charge anymore, due to imbalance of a cell i think.
he bought anothe full pack an replaced it. soo i bought the whole pack from him. for 2500 guilders, that s around 1375.00 usd. that s a steal if you ask me. but yeah no one on the island would know what to do with it.

sadly its a model y pack, soo long modules that wont fit in the car. i will try to rebuild the module and of course find the bad cell to remove it.
can i use the oem bms? battman? Damien's board is still in development i think. i read somewhere that you could talk or at least listen to the oem bms but i cant find the thread.

[tom91]

i will try to rebuild the module

good luck you will fail. You should have done more research before paying money for the pack that is fully glued together.

EV clinic do it but it looks like a process that needs a lot of practise

[PetersonOctavius]

went to test run today, motor spins but no torque!
my oil pump sounds different than when i had torque. now it sounds more like a humming. last time it sounded louder.
anyone knows what might be the issue?

- Mine hummed when I had a poor ground to controller
- possibly quieter now that you have put fluid in

[PetersonOctavius]

Hey Robert, im going to check my ground connection, the first tests were directly connected to the 12v battery pool. now i that i wired it to the chassis im getting the humming.

thanks

[PetersonOctavius]

Connected the oil pump directly to the 12v battery again, humming, no torque.
Also everything get very hot, everything as in pump, controller, even the cables.
First tests when i got torque were with thinner gauge cable, now running thicker cables but everything get hot

[PetersonOctavius]

Nvm… i messed up the UVW connection, pump was probably running in reverse

[PetersonOctavius]

The car came with an electric brake vacuum pump, which i want to use of course.
the pump relay needs a ground connection to run. which i found in the diagram, pin 22. tested it, the pump runs.

however, there is a brake vacuum sensor attached to the master cylinder. it has 3 pins.

according to the picture above:
pin 1 of the sensor goes to ground (not shown in the picture but i did test continuity in real life)
pin 3 goes to 5volts (D141 connection)
pin 4 goes to pin 18 on the oem ECU.

from the zombie, i connected 5v to pin 3 of the sensor and gnd to pin 1.
pin 4 i connected to GPA1 which i think is analog in, and the relay enable pin i connected to GPout3.
but i get no reading on the web interface.

did i think the sensor work too simple? so this is not a resistive sensor?
below i attached a picture of the sensor

[jrbe]

What do you see for voltage on pin 4 with a volt meter with it hooked up to 5v? Does it change if you put vacuum on it?
Might need a pull down or a pull up resistor depending on what you find.

[PetersonOctavius]

I ll check that , thanks… i did hook it up to an arduino, analog read. Gave me 195 constant with vacuum or not
Flipped the polarity of the 5v supply gave me 893

[jrbe]

An analog read of 195 of 1024 or?
If so and it doesn't change with applied vacuum, sounds like it might need a pull up resistor to 5v. You have a 100k or 47k resistor you can try when you're doing the meter / vacuum testing? If suggest trying this only if the analog value doesn't change with applied vacuum.

Reversing the power could destroy the sensor. So it might be shot.

[johu]

It looks like this sensor: viewtopic.php?p=9183&hilit=036906051G#p9183

Doesn't need any pull-up

[PetersonOctavius]

Yes indeed, that s the one i have. i ll keep on trying...hopefully i didnt break it somehow, noticed im really good at breaking stuff lately

[PetersonOctavius]

Hi there, anyone know where i can get new bearings for my gs450h oil pump?

Also i have a modely/3 bms main controller and the 4 modules that i dont think ill use. What price do those go fo? I can ship to the state

[PetersonOctavius]

While working on the battery boxes, i'm also configuring my Flying ADC Bmses.
Im using Samsung SDI battery modules from battery hookup for now.
they a 67Ah cells, they come in modules of 8s. i have 12 of those module to make 96s1p. in theory 24kWh.

they are rated at 3c ...3 x 67 = 201A peak. im not going to the track so i will limit my idc max to 100A or even less.
i just need to be able to cruise at 80kmh (not mph). not many "highways" on the island.

lucky enough, they came with temperature sensors installed. each module has 4 sensors.

my configuration will be 2x8s modules per bms board. 1 temp sensor from each module as the bms only has 2 temperature sensor inputs.
i upgraded my bms boards from 0.16 to 0.20B, to my surprise the default setting of 10000 of for temperature sensing worked right away.
i could watch my tempMin go up on savvy can as i held a light to the temperature sensor's metal tab.

i did a test drive today with the full battery pack installed, went well. i can confirm that the zombie vcu can control a camry inverter with the GS300H settings, connected to a GS450H gearbox.
but in my case, the rear differential's direction is opposite.

when i put the zombie in drive it spins the gs450h, clockwise which is normal. but my rear differential spins the wheel backwards. so in a sense fwd is reverse and reverse is fwd. i tried changing the phase cables but then MG2 wouldnt spin.
so i was okay with the idea of the reverse and fwd mixed up.
in the settings i changed throtmaxRev from the default 30 to 100.
but when i put the zombie in reverse to go forward, i get jitters. when i plot potnom and idc i realized when 30% potnom is reached, it drops to 0, idc also drops.

im running version 2.17A because with 2.20 i get weird behaviours like gearbox spinning without pressing the throttle.

[tom91]

2.17A has issues with resets triggering on GS300h gearbox that cause a judder.

You are running the GS300h? code are you sure you oil pump runs when driving?

There are very many reasons why your throttle behaves that way, you need to provide more logs and check things like error spot values.
Things like calibrate your throttle and setup all the limits propperly based on your setup.

In 2.20A the GS300h inverter currently does not work so I am surprised your Camry inverter works.

Big unkown in all of this what are the communication differences between the GS300h and Camry inverter, could be none, small or big.

[PetersonOctavius]

Yes, the oil pump starts on the inverter power trigger.
Its the loudest thing in the car right now, i don t know where to get new bearings for the pump. If i turn it off, the motor spins but the car doesnt move

My throttle is calibrated, i dont get no errors either. When in drive (the car moves in reverse) i dont get the sudden potnom drop
