DAY 2, running the GS450h, oil pump off.
still running fine, no unexpected behaviors, no unexpected noises.

today on my way to work, mg2 temp climbed steadily till 53 degrees C, AC on, oil pump off.
as soon as i turned on the oil pump, 40% duty, mg2 temp drops the 51 degrees C.
i drive a couple of ...

so far so good, nothing weird happened.
as exprected Mg2 temp is running slightly higher
normally MG2 gets to around 48-50 degree C when driving, today its was sitting more around 51-52 degree C
way to go

sooo, after mechanically locking the gs450h in HIGH gear and installing it back in the car, it wouldnt spin.... i got scared, but it was due to lose contact in the resolver wiring. after fixing that, the car drove fine.

i let it charge up and the next morning i drove it to work, oil pump ...

In theory getting rid of the external oil pump all together if possible.
The oil pump provide pressure for the clutch plates, you can choose high or low gear. But the oil pump is known to fail. No oil pump means no driving
Locking the gs in high gear means no oil pump yes driving
But no changing ...

hi, its been a while, after all my oil pump issues, i ended up buying another oil pump from Gregski.
been running fine ever since, on 40%
after a couple of moths of driving, i was cruising at around 60-70kmh, i had a torque loss, mg2 spun freely. i had to restart the car and it worked fine....for 2 ...

i ll be soldering my 6x17 caps today. and fix so muxshort fets.
the caps fit nicely between the fets legs. so that would make it easier to solder

check all the down in the spot values tab. you ll see if the cells are being discharged of charged

Yes worked on that, see latest commit.

Now where do we stand?
- I run v2.1, v2.3 and v2.4 hardware on a 96S system and it has survived multiple power cycles
- Mario runs 96S with v2.2, how does that go?
- Proton runs 96S now with v2.4 modules, works?
- Octavius runs 96S with capacitor patch, no ...

on 120v ac if you pull more than 10amps AC, the voltage drops so low that the charger resets itself, and tries again.

hahahahah those are some drastic measures

nice, you just changed 9600 to 115200? no changes to the nextion display?

when i have the vcu, isa shunt, dcdc conv, tesla charger turned on my screen updates right away.
but when i add the Flying ADC bms to the equation, the screen starts to update slower but not thaatttt slow like in the video

to get decimals in nextion you have to use the float element in nextion editor

ubalance should be around 3700 3800

Inverter temp max (default derate) is 85C
i think the motor temp (tmpm) is allowed to go quite high.
you ll have to monitor the temps during your first runs

have you used VESC?
i wasnt able to find a seller of those so i could try it out.

Hey jrbe, that's quite a sketch you made there. i understood it partially, im not that good of a designer, and here on the island the machineshops couldnt fabricate something like that.

the easiest way would be indeed to use the "dead pump" , ive attached a drone esc to it, it did spin and create ...

i m trying to do something similar, but still using the original oil pump head

Turns out My oil pump is "dead".
the main reason those pumps die seems (to me) to be water getting in the brushless motor of the pump, which then kills the resolver board. without a resolver the controller will not turn the pump. that s why i could make the brushless motor spin with a sensorless ESC ...

i ordered this pump

i opened, it seems to be a brushed dc motor, runs smooth.

when connected to 12.7volts, it pulled around 3-4 Amps.

its has a bigger and a smaller hole ...

after quite some days of driving around, same oil pump problem came back.
driving...after while the pump turns of. i've been running it with a separate PWM generator, 1kHz, 16%duty

i started to think its the oil pump controller.
i ve been building drones for almost 10 years now, so i have some ESC ...

quick run i did a while ago, potnom vs speed
never went above 6k rpm
negative rpm MG2 is forward on my setup

im going to log torque now

changed the code to 12500, both lines.
went for a test drive, 124Amps at 340 volts

New code will be then:

758 htm_data[81]=(12500)&0xFF; // discharge ability of battery
759 htm_data[82]=((12500)>>8);
