Abstract

The invention provides a storage battery pack and an automobile with a top-mounted electric drive operation function. The storage battery pack is applied to the automobile with the top-mounted electric drive operation function, the automobile comprises an engine, and the engine comprises a generator. A shielding power supply and a battery module of the storage battery pack are electrically connected with the generator through a battery pack charging circuit; a management module can control the battery pack charging circuit to be switched on to charge the shielding power supply and the battery module when the engine works, and control the shielding power supply and the battery module to output power to supply power to an engine starter; when the engine stops, the shielding power supply is controlled to stop outputting the power supply, and the battery module is controlled to output the power supply to power electric equipment on the automobile; and when the engine is started, the shielding power supply and the battery module are controlled to output power to supply power to the engine starter. The storage battery pack can be used for avoiding the situation that the automobile cannot be started due to power shortage of the whole automobile storage battery pack.
