HITACHI Inverter Teardown!! Audi e-tron. Wow it's Made in JAPAN !

Audi e-tron inverter disassembled. This inverter is quite small and has a high-density design.

When I see such thngs I sometimes wonder about how many engineers and thousands of hours have been involved. CAD/CAM, firmware developers, test engineers, materials experts, supply chain managers, project managers, endless nights at the office. All to make just one subsystem that most people who own the car will never see or think about.

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

[GLAJMAN]

Fantastic teardown dude. Will be watching for more.

[mikethemouse]

Awesome video!

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

No etron price makes more sense, that is a work of art!

[alexlo]

Very funny, Germany's cars don't use Siemens or ABB drive but

[venkateshpasupuleti]

Superb,
More informative.
Please do more videos on Body control module, Engine control module also.

Thankyou soo much for knowledge sharing.

I was hoping to see inside the power semiconductor modules

[ovpqokf]

Great video! Wondering if this inverter is used in my e-tron GT also. Hope so because it looks well made!

[EscritorioSP-up]

Looks like a perfectly repairable unit. I'm wondering if it is easy to find parts for this unit...

[ccshello]

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.

Really Informative! Thanks. Keep up your great work.

Nice work, very instructive, but i what is the specification of this inverter ?

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 YouTube. 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 😀.

So you had nothing to say about multiple seals inside of HV cavity opened to motor cavity, including push fit o-ring sealing fancy water jacket cavity with two different materials and irregular aluminium thickness? It seems to have high failure rate in just few years from introduction, as it obviously is full of reliability issues

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,

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?

[NoahHamlen]

I would've really liked to have seen the inside of the switching module. Video didn't have much novel substance without that

[drkastenbrot]

uncomfortable amount of sealing surfaces, hope it lasts

Its normal work most car company use electronic units from hitach Mitsubishi Motorola texas instruments general electric general mototors harris systems seimmens ABB sgs thomson samsung huwai TRW Ericson grunndig because they only do electronic units design and manufacturing car company only do mechanical produce parts its easy for companies to cost reduce
