Each line is individually controllable, which means that each line supports individual programming control, which is of great significance. This is “software and hardware decoupling”, long life, maintenance-free It is precisely because of this characteristic of semiconductor devices that Tesla’s All three BCMs are fully sealed, you can’t open them without tools, that is to say, non-professionals can’t maintain them. Based on the maintenance-free characteristics of the power distribution box based on semiconductor technology, the pure electric vehicle is compared with the fuel vehicle. There is no need to replace the oil filter, etc., and the maintenance cycle is longer. Now even the fuse box is maintenance-free. Another advantage of maintenance-free is that the power distribution box does not need an “accessible design”, which is very important for vehicle design. more friendly.
