Displays are made by LG and BMW also use LG screens . ... what comes from where is irrelevant .....it is what is manufacturer is demanding and how much time is given to engineering and software development to figure out everything before hitting the market....inverters IGBT are made by infineon and Bosch and DC-DC converter . ...L2 onboard charger and etc..... ADAS by continental.... Huber BMS....Electric brake system by ZF ...and list goes on..... Only company that can 3d print everything and know how everything will be possible without outsourcing anything..... So what people are buying this days is brand name... so if you think you are lost already . ...what you think how much time i spend reading and learning how all this I'm supposed to figure out when it is not working ..... there is completely new things that are required to know before you can work on EV....but once you understand logic and how are they interconnected. ..it is way more easier than ICE .....
