Battery pack integrated with vehicle body and vehicle with battery pack

Abstract

The invention discloses a battery pack fused with a vehicle body and a vehicle with the battery pack. The battery pack comprises an upper component, a lower box body, a high-low voltage assembly part and a battery module, the upper component comprises an upper cover body, a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, and the upper cover body is arranged above the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam; the lower box body is arranged on the lower portions of the transverse longitudinal beams, and the lower box body, the upper cover body and the transverse longitudinal beams define a containing cavity. The high-low voltage assembly part and the battery module are arranged in the accommodating cavity; the space is effectively utilized, a high-voltage element and a low-voltage control part in the battery are integrated, a module and a high-low-voltage assembly part are arranged in independent areas in the lower box body in a partitioned manner, and an internal low-voltage cable adopts a flexible wire bar to perform electric and signal connection on the module and the high-low-voltage assembly part, so that conformal design of internal wiring harnesses is facilitated; the safety of the battery system is improved, the weight is reduced, and the cost is saved.

Description

technical field [0001] The present invention relates to the technical field of battery packs, and in particular, to a battery pack integrated with a vehicle body and a vehicle having the same. Background technique [0002] The existing electric vehicle battery system is independent from the body, and is connected with the body by means of a battery-connecting bracket, which is not fully integrated with the body, occupies space, is heavy, and has high costs. The low-voltage wire bundle inside the battery is in the form of a cable, which is less flexible and has a large turning radius. The internal high-voltage components, low-voltage control components and the battery are mixed together, and the internal high-voltage and low-voltage copper bars and wiring harnesses intersect, resulting in a complex internal structure of the battery, which is not compact and concise, and is prone to wear risks. [0003] Electric vehicles are easy to meet low-emission and energy-saving goals, ...

Problems solved by technology

[0002] The existing electric vehicle battery system and the body are independent of each other, and are connected to the body by the battery-connected bracket, which is not fully integrated with the body, takes up space, is heavy, and costs high

The low-voltage wire harness inside the battery is in the form of a cable, which is less flexible and has a large bending radius

The internal high-voltage components, low-voltage control components and batteries are arranged in a mixed manner, and the internal high-voltage and low-voltage copper bars and wiring harnesses are intersected, resulting in a complicated internal structure of the battery, which is not compact and simple enough, and is prone to risk of wear and tear
