openinverter forum

Good afternoon, I bought an inverter from Honda Insight

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

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

You mean civic. No turns out there are slight difference but not massive. So the information on the Endless Sphere forum will be useful.

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 come from a separate block!!!

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 little later, after some time I will make inscriptions based on the photo, more detailed instructions, as I understand it, the inverter is from a Honda Civic, the capacitors are designed For voltages up to 600 В , but Honda insight has 450 volt capacitors , I couldn't find more detailed information on the capacities Special thanks to a good friend for providing the photo. Module IGBT For voltages of 600 and 300 А

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