Re: 2012 Camry Inverter AVV50R
Zechy, have you found out anything about the DC DC booster?
kind regards.

Re: 2012 Camry Inverter AVV50R
Team work
I'll see if I can get the DCDC to work. From what I read on the forum about the Prius DCDC converter, it should not be hard. The Camry connector also has 5 pins like the Prius, only it's smaller.

Re: 2012 Camry Inverter AVV50R
This is good.. I'll try this with my gs300h inveter running gs450h motor.. I get the same (tmphs error) whenever I start the inverter.. Have a question though. My gs450h motor and inverter was removed from a 2014 model and the inverter pinout is similar to that of gs300hZechy wrote: ↑Fri Dec 30, 2022 6:08 am Good news. I made a rookie mistake - bad wiring on serial comms.
I can now spin the motors using the Camry inverter.
Initially got a HS temperature error as soon as I started the motors.

(My motor temperatures are way off. Will have take a look at some point)
I cloned Damien's branch: git clone -b DM_Work https://github.com/damienmaguire/Stm32-vcu.git
From the data I captured it looks like the water temperature is only on column 20 so I changed the code to row 472:
temp_inv_water=mth_data[20];
I modified the GS300h profile to run the Camry inverter in this bin file: stm32_vcu_AVV50R.bin

I got a new Zombieverter board with the Wemos connector. My temperatures now work!

Re: 2012 Camry Inverter AVV50R
I'm running the Camry inverter with the GS450h gearbox quite successfully. My car is not on the road yet so just short test.
I get about 185amps from the inverter on full throttle.
One design mistake is that I only have 214V nominal and the motors don't like it. They start jittering when the battery drops to around 215V. Fully charged the pack is 240V. I've ordered more cells.

Damian has showed the GS450H motors running quite smoothly at around 60V on some of his videos from memory.Zechy wrote: ↑Sun Sep 03, 2023 5:16 am I'm running the Camry inverter with the GS450h gearbox quite successfully. My car is not on the road yet so just short test.

Did the extra voltage solve the motor jitter?

I also get the odd -27.71degC temp reading. Did you get to the bottom of this?Zechy wrote: ↑Fri Dec 30, 2022 6:08 am Good news. I made a rookie mistake - bad wiring on serial comms.

Re: 2012 Camry Inverter AVV50R
To be honest I can't recall if it started working. I switched to a 300h inverter because I couldn't get the jerking to stop. But I believe now it wasn't a Camry inverter issueJacobsmess wrote: ↑Tue Feb 13, 2024 2:37 pm I also get the odd -27.71degC temp reading. Did you get to the bottom of this?
I hope to revisit the Camry in the next few months

Re: 2012 Camry Inverter AVV50R
The voltage was a misdiagnosis. The jitter didn't change. I tried a 300h inverter which did the same.Electtic skids wrote: ↑Sun Jan 07, 2024 5:28 am OEM GS450h battery pack specs: motor 1KM, system voltage 650V, battery NiMH 288V 6.5 Ah

Today I managed to get the 300h working by defining the temp_inv_water as 8bit instead of 16. (see BMW Z3 discussion)
I think it will work for the Camry. Hope to revisit it in the next few months
