Very funny, Germany's cars don't use Siemens or ABB drive but buying.....Japan Hitachi!!!!!

Fantastic teardown dude. Will be watching for more.

wow interesting. Cant believe hitachi supplies audi. I dont think many japanese OEM uses hitachi as their INV suppliers

Really Informative! Thanks. Keep up your great work.

really interesting thanks for sharing

Awesome video! It would be also interesting to see the evolution of the parts "hidden" from the outsiders.

Superb, More informative. Please do more videos on Body control module, Engine control module also. Thankyou soo much for knowledge sharing.

Please open the switching module too.

Impressive

Hello fans of Mr. Ichiken and Mr. Ichiken 😀. This Hitachi inverter has already been presented by the host, but in the Japanese version. Full professionalism as usual! The three complex power transistors, or rather their configurations, are very impressive. I counted as many as 14 connections for each of them. Also the Infineon Technologies tri-core processor is very powerful. Mr. Ichiken pointed out the cooling channels and tabs that prevent the wrong assembly of power semiconductors. Like any device, it has the right to break down. I'm curious if it's worth repairing? I thought the simplest thing would be to replace the power transistors. But maybe I'm wrong. I invite fans to my new clip published on KZfaq. It presents an innovative system of functioning of the Brushless Hybrid Fast - Rotation Motor with complex coils of its own design based on the current of the sine function of two control lines. In the absence of a suitable four-phase inverter, it is powered by a frequency converter with single-phase current. Today I accelerated this mini machine to 300 Hz = 18 kRPM. Regards 😀.

Welcome to the globalized world. There are plenty of Japanese cars with SKF bearings, INA timing chains and belts, and Valeo heat exchangers. If you're impressed by a niche German hybrid using a Japanese inverter, you should research Aisin transmissions. It's all about the lowest bidder for the part specifications.

There is a few bits missing in the presentation. What is the exact input voltage for this inverter? Audi is not exactly a market leader in this field, so what sort of battery voltage do they use? Does it have a power rating? The two input capacitors should be easy to measure, what capacity are they? ESR?

Worthwhile to point out that this inverter does not use the boost-buck circuit* topology in-between the HV battery and the 3-phase drivers as Toyota does (* Boost: battery to IGBT driving motor; Buck: 3-phase rectifiers back to HV battery for charging) Also, A/C compressor's 3-phase HV motor's driver is not in this module.

Is it possible to repair the TCM of an Audi Q7? The Car was flooded with water, the TCM which is placed under the seat was submerged in water. The OBD tool shows defective TCM,

Very thorough examination. It looks complicated, thus many failure points. O-rings don't last forever. It looks expensive to replace. I think it would be more reliable to do away with the many o-rings and cooling ports. Submerse the entire unit in a dielectric. And simply use a heat pump type of cooling.

I don't like Japanese short cut of cables linked both modules it's like less caretaking .

electronics and water. will fail either way, owners prepate big money, but price will even be doubled in audi

"Promosm" 😪

Overly complicated and Overengineered
