Huawei developed the Drive ONE – three-in-one electric drive system. It includes seven major components – MCU, motor, reducer, DCDC (direct current converter), OBC (car charger), PDU (power distribution unit) and BCU (battery control unit). The AITO M5 car’s operating system is based on HarmonyOS, the same one seen in Huawei phones, tablets and IoT ecosystem. The audio system is engineered by Huawei too.
