IPM Settlement Check??

first i've heard of it. is that the result of a class action?

 

Take it to your bank. Ask them....
They should know, and/or could call and find out before depositing it.
And then when it doesn't clear, charge YOU!

 

Did you have a problem with the inverter and paid to have it fixed and then submitted a claim for reimbursement for the cost to have it fixed? If so, the check is legit.

Who is the check from?

 

Besides getting a check for a repaired inverter, there is an IPM check being sent out.

I searched a little and quickly found that people are getting a $350 check.


Looks like you would have had to filled out something a while back.

Not sure if owners who had the two updates, E0E and J0V would be automatically included.

This is besides anyone getting a check for a repair made to the inverter.

20 million was to be disbursed.

 

What does IPM stand for?

 

Intelligent Power Module

 

Or integrated power module, depending on where you look. It is basically a single electronic unit that combines several big IGBTs (insulated-gate bipolar transistors) along with simple driver circuits and some sensors for temperature, maybe current, etc.

A small one, as you might find in a 3 kW DC to AC inverter, looks sorta like this:



The connections to the DC power bus are the big terminals at the left, the switched power outputs are the big ones below, and the small gold connector pins in the middle are the control inputs and sensor outputs. The other face not shown in this picture is all metal, and you would bolt it down to a large heat sink to carry the heat away.

The one inside a gen 3 Prius looks like this:



You can see the big bolted power connections along the edges, and the small ribbon-cable connector for control and sensors near the middle of the board. From the pipe nipples, you can see that the Prius one even includes its own liquid coolant passages.

There isn't really much 'intelligence' to it; it just combines some big transistors and associated sensors. The intelligence will be in some ECU that is pulling the strings, like the gen 3 MG ECU that mounts above the IPM and looks like this:
