Report overview

The second BEV (battery electric vehicle) from the Chinese home appliance manufacturer Xiaomi, the Xiaomi YU7, was released in June 2025.
The YU7 is available in three grades: Standard (RWD), Pro (AWD), and Max (AWD). In addition, the Xiaomi YU7 is equipped with three types of body controllers: Front, Right, and Left.
This report presents the teardown analysis of the integrated ECU(BCM FRONT, LEFT, and RIGHT) installed in the Xiaomi YU7, as well as the PCB layout analysis of the BCM FRONT unit manufactured by Continental.

Product Features

A large number of press‑fit connectors are used.
A jumper is mounted on the top side of the PCB, which is presumed to be intended for securing sufficient current‑carrying capability.
There are many resist openings on the bottom side of the PCB, and together with the thermal resin applied to the enclosure, they are presumed to be intended to improve heat dissipation efficiency
