Abstract

The invention relates to the technical field of new energy automobiles, and discloses a high-voltage distribution box, a lower shell assembly thereof, a power battery system and an automobile. The lower shell assembly comprises a lower shell (10) and a pre-charging resistor (11), and a groove (12) is formed in the lower surface of a bottom wall (17) of the lower shell (10); the groove (12) is provided with a pre-charging resistor fixing structure used for fixing the pre-charging resistor (11), and the groove (12) is provided with a through hole (13) so that a connecting plug of the pre-charging resistor can be exposed out of the top surface of the lower shell (10). The layout of the lower shell of the high-voltage distribution box is more compact, the space is saved, and the layout of the high-voltage distribution box is more reasonable.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a high-voltage distribution box and its lower housing assembly, a power battery system and a vehicle. Background technique [0002] As an important power source for new energy vehicles, the power battery system provides a steady stream of driving power for new energy vehicles, and the high-voltage distribution box is the core component of the power battery system, which contains various high-voltage electrical components to distribute and control power in real time The output current of the battery system plays an important role in the safe, stable and reliable operation of the power battery system. [0003] At present, there are many high-voltage electrical components in the power battery system, and the scattered layout needs to occupy a large space of the power battery system. The high-voltage electrical components of the power battery system cannot realize module ...
