It would be interesting to see a photo

I am building a Lebowski small board with bare minimum interface pins.
My intent is to use the same board with IMA 1B210RBJ0131 and 1B300RMX0031 units. the way Romale shows here...

With small one i will need to use external current ...

the current sensors can take a bit over 300A: https://endless-sphere.com/sphere/threads/yet-another-lebowski-honda-ima-inverter-step-by-step.119952/#post-1764979

Well, it will be possible to adjust how Roman did it, add a resistor, the Honda Civic is an excellent inverter, due to the built-in ...

Ok you peaked my interest now. I have some questions...
1. Does this particular inverter stop by itself at voltage more than 240Vdc?
Yes, it stops, there is voltage protection for the Honda Insight inverter, there is no protection for the Honda Civic inverter, and it can operate up to 550 volts ...

From the entire list, only one inverter has logic, the Honda civic, the rest of the inverters take PWM from the control unit, they are easier to start, but the Honda insight, crz, jazz, fit inverters have an external current sensor, since the Honda civic current sensors are already in the inverter ...

What is the IPUA signal level when active? Is it GND level or positive?

tnx


Upua is the TX UART contact; the inverter communicates with the native control unit through it. The inverter operates and starts without it, with operating voltage up to 240 V, then it shuts off. Some guys have removed ...

VCC This voltage is 12 volts, powered by a battery, Ipua This is an error signal

There is a fee openinverter 3 version It works well with the Honda Civic inverter, the resolver pinout can be found using a tester

It's also this one: https://openinverter.org/forum/viewtopic.php?p=25763#p25763

Based on the silkscreen, OP also has a 2014-2018? HAH inverter, which is Honda's first generation PCU, documented in some depth here: https://git.laboratoryb.org/hurricos/ClaritySwap/raw/branch/master/Electricals ...

The pinout of the current sensors is ready, let's move on along the path

Thats how Toyota done the early priaiii (plural of prius) too so it seems very possible. I would mean getting control over the inverter power stage should be "relatively" straight forward once signals are identified and mapped.

Yes, I am working on it, for now we have a diagram like this, a ...

Same as the honda IMA I think. They have been reverse engineered for some time
Edit: as Tom points out


Not exactly, the Civic inverter has logic already inside the inverter, I may be wrong, but the inverters are Insight, Jazz,Fit, you can run it directly through the connector, the PWM signals ...

We continue disassembling the inverter, the top cover is held on by 4 bolts , Also disassembling current sensors

Good afternoon, I bought an inverter from Honda Insight

How the project ended

The current sensor has a pinout
Green ,Gray, pink - Signal output
White, blue, light green GND
Red, yellow, Brown VCC
I marked them in the Current sensor from inside]

Cool, another Honda, so not this one? https://openinverter.org/forum/viewtopic.php?t=3545

No, this is a Honda Accord inverter, another author has a Honda Civic inverter, But I have an inverter from a Honda Civic, Insight (Jazz and Fit), Honda Accord inverter current sensors have a power supply ...

.

Good afternoon, I'm I'm a newbie here, maybe someone will find the information on the inverter useful Honda Accord and its disassembly

In 3 Prius or Aqua

Everything has its time, at least managed to move in the project with the help of arduine, twist

Why did you decide so, I think many will be interested in the inverter honda insight, fit Due to its compactness and cheapness, and the connection is easy through the connector chip

cool, we are waiting for the article, I think a lot of people would be interested in the fit inverter and insight
